Abstract:

Two systems of relay-intercropping muskmelons (Cucumis melo L.) with Scotch pine (Pinus sylvestris L.) Christmas trees using black plastic mulch and drip irrigation were evaluated for their potential to improve cash return. Returns ranged from a high of $26,200/ha for plastic mulch-drip irrigation and a selling price of $l.00/melon to a low of $6900/ha for bare ground-drip irrigation and a selling price of $0.40/melon. The benefit-cost index ranged from 24 to 3.4, depending on the system evaluated. Pine growth apparently was impeded by plastic mulch; however, increased yields of melons grown under plastic mulch may offset the slight decrease in pine growth.

Abstract:

Post tin mining tailings land in Bangka Belitung Islands Province has an area of around 400 000 ha. In terms of area, the land has the potential to be used as cultivated land, one of which is melon. The aims of the study is to see the effect of cow manure fertilizer and drip irrigation water volume on melon plants growth in post tin mining tailings area. This research was conducted from June to August 2018 in the tailings area of Dewi Makmur Village, Merawang District, Bangka Regency. This experimental used a completely randomized design (CRD) factorial method. The first factor was cow manure with three levels (K1 = 2.5 kg/planting hole; K2 = 5 kg / planting hole; K3 = 7.5 kg / planting hole) and the second factor was drip irrigation volume (A1 = 800 ml; A2 = 1 500 ml). The results showed that giving cow manure and water irrigatian has no significant effect on melon plant height, stem diameter and number of leaves, but the treatment 7.5 kg of cow manure and 1 500 ml water gave results that tended to be better.

Abstract:

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

Abstract:

ABSTRACT The objective of this work was to determine the water consumption and the crop coefficient of melon in a protected environment. The experiment was conducted in a greenhouse at the Technical Center of Irrigation of the State University of Maringá, in Maringá, PR. The melon hybrid used was Sunrise and the irrigations were performed daily by drip irrigation. Crop water requirement was quantified based on its evapotranspiration directly measured through constant water table lysimeters. Weather information was collected in an automatic weather station, installed inside the protected environment, which allowed to calculate the reference evapotranspiration by the Penman-Monteith method. The total water consumption of the melon crop was 295 mm, reaching maximum crop evapotranspiration of 5.16 mm d-1. The phenological stages were shorter in the initial, growth and intermediate phases, compared with the data from FAO. The determined crop coefficients were 0.87, 1.15 and 0.64 for the initial, intermediate and final stages, respectively

Abstract:

ABSTRACTDetermination of the appropriate volume of irrigation is needed in hydroponic systems. The easy and rapid method for determination of volume irrigation should be developed. The research was conducted to determine irrigation volume based on evaporation and to study their effect on melon growth and yield in hydroponic system. The irrigation water volume was determined based on evaporation (E) of the 30 cm diameter pan placed over the crop canopy, and melon (Cucumis melo L.) plant was subjected to four irrigation water levels (0.5, 1.0, 1.5, and 2.0 E) in combination with three periods of irrigation based on plant growth phase ( planting to harvesting; planting to flowering, and flowering to harvesting). At three weeks after planting, irrigation volume of 1.5 E increased plant height as much as 54% compared with irrigation volume of 0.5 E; irrigation volume of 2.0 E increased leaf number as much as 47% compared with irrigation volume of 0.5 E. Melon yield was 2.173 kg per plant by irrigation volume of 2.0 E applied during planting to flowering, increased of 98% compared with irrigation volume of 0.5 E, but it was not significant different with irrigation volume of 1.5 E applied during flowering to harvesting. It is concluded that irrigation volume for hydroponically-grown melon was as much as 1.0 time of evaporation during vegetative phase and 1.5 times of evaporation during generative phase.Keywords: evaporation, sand media, flower number, fruit diameter, fruit weight

Abstract:

Multistate and international foodborne illness outbreaks, particularly involving cantaloupe and often involving rare Salmonella spp., have increased dramatically over the past 13 years. This study assessed the sources and extent of melon rind contamination in production fields and at processing and packing facilities. In the spring of 1999, cantaloupe (Cucumis melo L. [reticulatus group] cv. Cruiser) sampled from two sites in the Rio Grande River Valley showed that postharvest-processed melon rinds often had greater plate counts of bacterial contaminants than field-fresh melons. Cantaloupe in the field had 2.5 to 3.5 log CFU g−1 rind total coliforms by aerobic plate counts, whereas washed melons had 4.0 to 5.0 log CFU g−1. In the fall of 1999, coliforms on honeydew melons (C. melo [inodorous group] cv. Honey Brew) ranged from 2.6 to 3.7 log CFU g−1 after processing, and total and fecal coliforms and enterococci never fell below 2.5 log CFU g−1. A hydrocooler at another site contaminated cantaloupe rinds with up to 3.4 log CFU g−1 total and fecal enterococci; a secondary rinse with chlorinated water incompletely removed these bacteria. Sources of coliforms and enterococci were at high levels in melon production soils, especially in furrows that were flood irrigated, in standing water at one field, and in irrigation water at both sites. At one processing facility, wash water pumped from the Rio Grande River may not have been sufficiently disinfected prior to use. Because soil, irrigation water, and process water were potential sources of bacterial contamination, monitoring and management on-farm and at processing and packing facilities should focus on water quality as an important control point for growers and packers to reduce bacterial contamination on melon rinds.

Abstract:

Hydroponic cultivation of melon plants with a fertigation system using ground water is one of the cultivation technologies that is expected to improve the quality and production of crops. Fertigation technology (fertilizer and irrigation) using autopot is an irrigation system allow to provide irrigation water by self-watering system by not using electric power so that the fertigation system is more efficient. The purpose of this study was to determine the effect of the impact of groundwater quality on the quality of melon (Cucumis melo L.) plants. The research method used is descriptive method. The quality parameters of the melon used in this study were water content, carbohydrate, protein, fat, ash, vitamin C and sweetness (% brix). The results of research on ground water quality show that the quality of ground water used is included in the category of non-polluted, which means that the water has good quality. The results showed the quality of melon has an average value of 95.19% fruit water content, 1.99% carbohydrate content, 1.37% protein content, 0.88% fat content, 0.57% ash content, vitamin C 6 , 91%, and total dissolved solids (sweetness) 9.4 0brix. The quality of the melon is classified as low quality according to SNI 7883-2013. The results of the ground water quality and the quality of the melon shows if the ground water affects the quality of the melon plants.

Abstract:

The effects of boron and effluent (treated sewage water) on vegetative growth, fruit yield, and boron uptake of grafted and nongrafted melons (Cucumis melo L. cv. Arava) were studied. Nongrafted melon plants and melon plants grafted onto the commercial Cucurbita maxima Duchesne × Cucurbita moschata Duchesne rootstock ‘TZ-148’ were grown in pots filled with perlite in a heated greenhouse and were irrigated with fresh water or effluent. The two irrigation waters contained boron in five concentrations ranging from 0.1 to 10.4 mg·L−1. The boron concentration in the plants increased linearly with that in the irrigation water. The highest boron concentrations were found in old leaves, the lowest in the fruit, and intermediate concentrations were noted in the roots. The boron concentrations were, in general, significantly lower in grafted than nongrafted plants, possibly because the root system of the former had higher selectivity and lower boron absorption than that of the latter. Fruit yield and dry weight accumulation in shoots and roots decreased linearly as the boron concentration in the irrigation water increased, the nongrafted plants were more sensitive than grafted ones to the boron level, and both were more sensitive under fresh water irrigation than under effluent irrigation. It is suggested that the higher boron sensitivity of the root systems of the nongrafted plants probably decreased their capability to absorb water and nutrients, which in turn sharply reduced their fruit yields.

Abstract:

Plastic mulch ground cover and drip irrigation have produced substantial increases in yield and earliness of melons. However, such practices affect water movement, and nutrient and salt distribution in the soil. Salt levels in the soil after a melon crop using drip or flood irrigation increased in bare soil but decreased where plastic mulch had been used. Apparently capillary rise of water in response to surface evaporation brought salts up into the root zone. Very little of the applied N was detectable at the end of the study. However, enhanced early vine growth due to N application where drip irrigated but not where flood irrigated indicated that flood irrigation may have caused earlier N losses. Yield responses to N regardless of irrigation method indicated that early availability may have been most important. Yield increases were found for drip vs flood irrigation, and for plastic mulch vs bare soil, both of which may have been earliness effects; but the later treatments did not get the chance to catch up due to the occurrence of vine decline.

Abstract:

ABSTRACT The use of saline water for irrigation causes severe restriction to nutritional balance, growth and production in many crops due to the effect of salts on plant and soil. The objective of this study was to investigate the response of melon (Cucumis melo L.) cultivars to various levels of irrigation water salinity on yield and fruit quality. A field experiment was conducted in a split-plot randomized block design with four replicates. The factors were five levels of irrigation water salinity (0.54, 1.48, 2.02, 3.03 and 3.90 dS m-1) in the plots and five melon cultivars (C1 - Sancho - Pele de sapo; C2 - Medellín - Pele de sapo; C3 - Mandacaru - Canary; C4 - Néctar - Galia; C5 - Sedna - Cantaloupe) in the sub-plots. According to the results, among the five genotypes studied, Sancho was the most salt-tolerant genotype, followed by Mandacaru, Medellín, Sedna and Néctar. Since irrigation water salinity did not influence the mean fruit weight, the reduction in the number of fruits was the main cause of yield reduction of the melon crop under high salinity water. The contents of total soluble solids increased under high salinity level.

Abstract:

Cropping intensification and technical, economic and environmental issues require efficient application of production factors to maintain the soil productive capacity and produce good quality fruits and vegetables. The production factors, water and NPK nutrients, are the most frequent limiting factors to higher melon yields. The objective of the present study was to identify the influence of subsurface drip irrigation and mulching in a protected environment on the water and NPK nutrients productivity in melon cropped in two soil types: sandy loam and clay. The melon crop cultivated under environmental conditions with underground drip irrigation at 0.20m depth, with mulching on sandy loam soil increased water and N, P2O5 and K use efficiency.

Abstract:

Salinity and water deficit are two major issues for agricultural development in Algeria. The Lower Cheliff plain, northwestern Algeria, is, furthermore, characterised by semi-arid Mediterranean climate, and soils with high clay content. Our study area was a 4 ha farm located in Oued Rhiou and another 1 ha farm located in Ouarizane, both upstream in the Lower Cheliff plain, and irrigated with waters of different salinities: 1.8 and 5.5 dS m-1, respectively. The plots were equipped with drip irrigation and subsurface drainage systems. Farmer’s irrigation management of artichoke and melon were observed during the respective cropping seasons from September 2010 till June 2011, and from April till July 2011. The total irrigation amounts were, respectively, 364 mm and 240 mm, while the precipitations were 367 mm and 67 mm. The soil properties were determined in the entire rooting depths down to 80 cm for artichoke and 60 cm for melon. In addition to these, irrigation water composition, and crop development parameters were used to simulate soil salinity using the SALTIRSOIL_M model. Simulations and observations of soil pH, main ion concentrations and ECe showed reasonable agreements for June 2011. Next, the irrigation schedules that would have met the water needs of both crops, while simultaneously keeping soil salinity below harmful levels were estimated using the model. For the artichoke plot, a lower irrigation rate (290 mm yr-1) could have kept water deficit and soil salinity below their respective harmful thresholds. For the melon plot, on the contrary, a higher irrigation rate (480 mm yr-1) is able to neutralise the water deficit, though not completely the salinity stress would have been adequate. Farmers’ irrigation practices in the context of the climate, water quality and soil properties of the Lower Cheliff plain can be analysed and improved with the aid of soil salinity modelling.

Abstract:

The shortage of good quality water in semiarid zones necessitates the use of saline water for irrigation. In order to simulate the usage of brackish irrigation water in greenhouse melon (Cucumis melo L. cv. Galia) culture in perlite, plants were supplied with nutrient solutions containing 0 (control), 20, 40, and 60 mm NaCl applied at four different times. Treatments were applied during early vegetative growth [14 days after transplanting (DAT)], beginning of flowering (37 DAT), beginning of fruit set (56 DAT), and beginning of fruit ripening (71 DAT). All vegetative and fruit yield parameters were significantly reduced when salinization was started 14 DAT. This inhibitory effect of salinity was progressively lessened when salinity was imposed at later dates. This suggests that the response of melons to salinity depends on the duration of exposure to saline water. Salinity treatments increased fruit reducing sugars, acidity, and total soluble solids. Fruit yield reduction at each salinization time was correlated with salinity levels, but there was some evidence of a nutrient imbalance, since leaf concentrations of N-NO3, and especially K, were low at higher salinities. These results indicate that brackish waters can be used for growing melon with minimum yield losses if concentration and duration of exposure are carefully monitored.

Abstract:

A field study was conducted in south Texas in the spring 1990 to determine the effects of ground cover, planting method and drip irrigation rates on cantaloupe growth, yield and quality. Transplanting vs. direct seeding enhanced early vine growth with earlier yields, although direct seeding later caught up resulting in comparable final cumulative yields. Black polyethylene mulch also improved earliness but at the loser irrigation rate total yields were reduced due to deflection of rainfall by the mulch. Irrigation at .1, .3, .5, .7 and .9 times pan evaporation had little effect on final cumulative yields with exception to the .1 and .3 rates. Melon sugar content was highest for transplants with direct seeded melons becoming comparable only at mid to final harvest. The combined practices of transplanting and black polyethylene mulch resulted in a 14 day earliness advantage over the treatments that were direct seeded on bare soil although final yields were unaffected. No appreciable increase in soil salinity were found as a result of drip irrigation usage.

Abstract:

It was to aimed it to investigate effects of various saline water use strategies on melon production and quality of two cultivars (Cucumis melo L., Sancho - C1 and Medellín - C2. The plants were irrigated with water of low (S1 = 0.61 dS m-1) and high (S2 = 4.78 dS m-1) salinity levels, during each crop stage: S1S1S2S2 - T1; S2S1S2S2 - T2; S2S2S1S2 - T3. The 1st, 2nd, 3rd and 4th terms of these sequences correspond to initial growth, flowering, fruit ripening and harvest phenological stages, respectively. Additionally, there was irrigation rotation during all cycle, with water S1 during two days followed by S2 for one day (S1 2 dias + S2 1 dia - T4) and irrigation with non-salt water S2 during all cycle - T5. Moreover, we used as control, the irrigation water at 3.2 dS m-1 resulting from water mixture of S1 and S2 - T6 (farm used irrigation management). The experiment was carried out in Pedra Preta Farm, in Mossoró, RN, using an entire randomized block statistical design in a 6x2 subdivided plot scheme with four replications. Saline water irrigation at initial growth stage reduces leaf area and shoot dry phytomass of Sancho and Medellín melon cultivars. The irrigation by T4 provided the highest phytomass production of fruits at 48 DAS, reducing in 33% of good quality water in irrigation.

Abstract:

ABSTRACT The melon is an outstanding fruit crop in Brazil, mainly in the Northeast region due to favorable conditions for cultivation. Water salinity affects the growth and production of several species, but there is tolerance among cultivars of the same species. The objective of this study was to evaluate the growth and gas exchange in melon seedlings subjected to water salinity. Experiment was carried out in a greenhouse belonging to the Center of Sciences and Agri-Food Technology, Federal University of Campina Grande, Pombal, PB, Brazil, from September to October 2016. The experimental design was a randomized complete block design in a 6 x 5 factorial scheme, with four replicates, for six cultivars of melon (Natal, Solares, Goldex, Iracema, Mandacaru and Amarelo Ouro) and five irrigation water salinity levels with the following electrical conductivities: 0.3, 1.1, 1.9, 2.7 and 3.5 dS m-1. Each experimental unit consisted of a polypropylene container with a volume capacity of 0.350 dm3, which contained soil + Basaplant® commercial substrate at a ratio of 2:1. At 25 days after sowing, the plants were evaluated for growth, gas exchange and dry mass accumulation. Increased salinity of irrigation water inhibits the growth, dry mass accumulation and physiological processes of melon cultivars. The cultivar Natal showed to be more tolerant, while the cultivars Solares, Goldex, Iracema and Mandacaru were moderately sensitive and the cultivar Amarelo Ouro was more sensitive to the salinity of irrigation water.

Abstract:

ABSTRACT The leafminer [Liriomyza sativae (Diptera: Agromyzidae)] is one of the main pests of melon crop (Cucumis melo) in the states of Rio Grande do Norte and Ceará. Thus, adopting strategies to control this destructive insect is essential. The aim of this study was to evaluate the effect of aqueous neem seed extract, applied to soil via irrigation, on leafminer larvae, in the melon crop. An experiment was conducted in greenhouse, in completely randomized design, consisting of five treatments (four doses of aqueous neem seed extract: 1; 3; 5 and 10 g/100 mL) and the control consisting only of distilled water and 10 replicates (melon plants). The treatments were applied in a single dose, via soil irrigation. In the first stage of the evaluation, 24 hours after application, the number of dead larvae per plant was counted. In the second step, pupal mortality was recorded. The total mortality was also calculated considering the number of larvae and the number of emerged adults. We verified that, increasing the concentration of aqueous neem seed extract, an increase in the larval and pupal mortality of the leafminer in melon crop was noticed. The concentration 10 g/100 mL presented the best results, resulting in 36.4% of larval mortality, 96.5% of pupal mortality and 96.8% of total mortality.

Abstract:

Fruit cracking affects many types of crops and is a major problem since the breakage of the surface of the fruit produces high economic losses. Numerous studies have looked at different ways to prevent this, mainly in melon, but with a low success rate. In this work, a standardisation of the induction of cracking is proposed that involves changes in the irrigation pattern (high conductivity or double irrigation). The prevention of the appearance of cracking was carried out through different foliar mineral treatments. The incidence of cracking was studied in relation to gas exchange variables and the concentrations of minerals in tissues. Our results show a more pronounced increase in cracking with double irrigation. Multiple elements were found to be associated with cracking such as B, Ca, K, Mg, Mn, Na, P, and Zn. Furthermore, foliar application of different microelements (B, Cu, Fe, Mn, Mo, and Zn) decreased the melon cracking incidence, thus assigning to the appropriate combination of these elements a crucial role in cracking amelioration.

Abstract:

The objective of this study was to evaluate the effect of different irrigation blades on the presence and absence of biofertilizer on the agronomic performance of the ‘Cantaloupe’ melon in the Paraíba backwoods. The work was conducted under field conditions in the Agroecology Sector, belonging to the State University of Paraíba (UEPB), Campus IV. The experimental design was a randomized block using four irrigation blades (60, 80, 100 and 120% - ET0, (mm day-1)) with presence and absence of biofertilizer replicated six times. The following variables were evaluated: main branch length, leaf area, number of leaves, phytomass aerial part, pulp diameter, soluble solids, bark diameter, number of seeds per fruit, seed weight per fruit and weight of 100 seeds. The irrigation blade of 120% of ET0 promoted greater growth and development since biofertilizer application provided a greater number of seeds per fruit and weight of 100 seeds, there was no interaction between the factors studied in both variables evaluated in the Cantaloupe melon.

Abstract:

The modern techniques of water supply through irrigation can substantially reduce water waste, which contributes to attend the enlarging water demand. The objective of this work was to study the influence of subsurface drip irrigation and mulching over melon yield and quality characteristics, in a sandy soil (Typic Hapludox). The experimental design was blocks at random, with four replications. Treatments were displayed in a 2 x 3 factorial (with and without mulching x surface and 0.20 and 0.40 depth subsurface drip irrigation). Mulching using double-sided silver/black film increased fruit average mass, plant production, yield, daily growth rate for plant height and crown diameter, fruit distal diameter, and pulp thickness. The subsurface drip irrigation at 0.20 m depth resulted in larger fruit average mass, plant production, and yield than surface and 0.40 m depth drip irrigation.

Abstract:

Relevance. In recent years, the price of seeds for melons and gourds of foreign selection has reoriented many agricultural producers to use seeds of domestic varieties. To provide agricultural producers with the required amount of seeds with high sowing rates, it is necessary to apply new technological methods that will allow using the biological potential of varieties and growing commercial volumes of seeds.Material and methods. The research was carried out at the selection and experimental site of the vegetable growing department in the "Federal Scientific Rice Centre " in 2017-2018. The object of research is a new promising variety of watermelon Yubilyar, and two early-ripening varieties of melon Tamanskay and Strelchanka. Sowing terms: spring – from mid-April to the end of the first decade of May, summer – the first and second decades of July. Summer sowing with drip irrigation. When harvesting melon and watermelon fruits, the selection intensity is 90% to obtain reproductive seeds RS-1.Results. It has been established that due to the climatic conditions of the Krasnodar Territory and the varietal characteristics of the melon varieties Tamanskaya, Strelchanka and the watermelon Yubilyar, a short growing season and a neutral reaction to changes in the length of the day, you can get two harvests of seeds in one season using summer sowing. It was noted that low air humidity prevented damage to plants by peronospora, anthracnose and powdery mildew, practically eliminating the need for protective measures. The selected ripe fruits for the selection of seeds by morphological characteristics corresponded to varietal characteristics. It has been established that the seed productivity of melon during summer sowing is higher due to better pollination. From one hectare received up to 97-138 kg of seeds. The use of ripening made it possible to carry out a one-time collection of watermelon and melon fruits.

ABSTRACT The objective of this study was to analyze technically and economically the irrigated ‘Gália’ melon (Hybrid Nectar), cultivated in greenhouse with and without using plastic mulch covering on the soil. Simultaneously, two experiments were conducted using a completely randomized design (CRD), in which melon plants were submitted to five water availability levels, defined by 50, 75, 100, 125, and 150% of crop evapotranspiration, with four replicates. The difference between experiments were only about the soil covering with plastic mulch: with (CC) or without (SC) plastic mulch. The economically optimal irrigation depths were 208.83 and 186.88 mm, resulting in yields of 50.85 and 44.51 t ha-1 for the experiments with and without mulching, respectively. The results showing the economically optimal irrigation depths were very close to those that produced the highest yield.

Abstract:

The melon crop is normally developed in semiarid regions, where water resources are limited. This scarcity of water is a strong stressor on the crops, and requires the supplementation of existing water supplies with poor quality water, especially saline water. This can impede the growth and production of plants; however, the use of tolerant genotypes may minimize this problem. Thus, a greenhouse experiment was developed at the Federal University of Campina Grande - UFCG, Pombal Campus, Paraiba State, Brazil, in order to study the emergence, initial growth, and tolerance of melon cultivars irrigated with waters of different salt content. We studied three melon cultivars (Gaúcho Redondo, Gaúcho Casca de Carvalho and Halles Best Jumbo) irrigated with five levels of saline water (0.6; 1.2; 1.8; 2.4; and 3.0 dS m-1), arranged in a 3 x 5 factorial scheme, with the treatments distributed in a randomized block design with four replications. The plants seeds were monitored for 30 days after sowing, and at 30 days the growth and salinity tolerance index was evaluated. Cultivar Halles Best Jumbo was the most tolerant to saline water during initial stage of growth, while the Gaucho Redondo was more sensitive to salinity. It was found that saline waters up to 1.8 dS m-1 were suitable for irrigation of melon plants round Gaucho and waters up to 2.4 dS m-1 could be used for irrigation of Gaucho Casca de Carvalho and Halles Best Jumbo crops during the initial growth phase.

Abstract:

Excess of boron and salinity in soil and irrigation water can limit the production of melons (Cucumis melo). A greenhouse study was conducted in order to compare the responses of grafted and non-grafted melon plants to combinations of high levels of boron and salinity. Boron levels were 0.25, 0.8, 2.5, 5.0, 10.0 mg·L-1 and salinity levels were 1.8 and 4.6 dS·m-1. Foliar injury caused by boron was more severe in the non-grafted than in the grafted plants. Likewise, boron accumulation in leaf tissue from non-grafted plants was higher than in grafted plants. High salinity led to decreased boron accumulation in the leaves. Fruit yield was decreased only at a boron concentration of 10 mg·L-1, and the decrease in grafted plants was smaller than that in non-grafted plants. A negative correlation was found between boron accumulation in leaves and fruit yield. The results showed that melon plants grafted on Cucurbita rootstock are more tolerant than non-grafted ones to high boron concentrations, and this can probably be explained by the decrease in boron accumulation caused by the rootstock.

Abstract:

Nitrogen (N) is an important nutrient for melon (Cucumis melo L.) production. However there is scanty information about the amount necessary to maintain an appropriate balance between growth and yield. Melon vegetative organs must develop sufficiently to intercept light and accumulate water and nutrients but it is also important to obtain a large reproductive-vegetative dry weight ratio to maximize the fruit yield. We evaluated the influence of different N amounts on the growth, production of dry matter and fruit yield of a melon 'Piel de sapo' type. A three-year field experiment was carried out from May to September. Melons were subjected to an irrigation depth of 100% crop evapotranspiration and to 11 N fertilization rates, ranging 11 to 393 kg ha-1 in the three years. The dry matter production of leaves and stems increased as the N amount increased. The dry matter of the whole plant was affected similarly, while the fruit dry matter decreased as the N amount was increased above 112, 93 and 95 kg ha-1, in 2005, 2006 and 2007, respectively. The maximum Leaf Area Index (LAI), 3.1, was obtained at 393 kg ha-1 of N. The lowest N supply reduced the fruit yield by 21%, while the highest increased the vegetative growth, LAI and Leaf Area Duration (LAD), but reduced yield by 24% relative to the N93 treatment. Excessive applications of N increase vegetative growth at the expense of reproductive growth. For this melon type, rates about 90-100 kg ha-1 of N are sufficient for adequate plant growth, development and maximum production. To obtain fruit yield close to the maximum, the leaf N concentration at the end of the crop cycle should be higher than 19.5 g kg-1.

Abstract:

In Mossoró-RN, which is part of the semi-arid region of Brazil, a large part of the country’s melon production is concentrated, whose great potential is currently limited by water quality due to salt concentration. Therefore, the objective of this work was to investigate the use of saline nutritive solutions in the irrigation of greenhouse melon (Cucumis melo L. cv. Néctar) culture in coconut fiber. The experiment was carried out using a randomized block design with a 5 x 2 factorial arrangement, with four replications, where the treatments consisted of nutritivesolutions with five salinity levels (1.25 - control, 1.43, 1.86; 2.96 and 4.86 dS m-1) and for two different times to evaluate fruit quality parameters (at harvest and after 12 days of storage). Increasing the salinity in the nutrient solution reduces fruits’ mean weight, while total yield is only reduced with EC above 3.5 dS m-1. Fruit length anddiameter and peel and pulp thickness, SS and pH, decrease when submitted to nutrient solution with EC above 3.8 dS m-1. The peel and pulp thickness, pulp internal cavity, firmness, SS, pH, TA and fruit SS/TA ratio were influenced by the storage period.

Abstract:

In the Caborca area, water scarcity is the main problem for the farmers, because of the depletion of the aquifer. This is the main reason why they are focusing on orchards and vegetables. Melon is the vegetable annual crop more extensively grown in this area and is furrow-irrigated with 120 cm of water. But, because of the scarcity of water, it is necessary to use drip irrigation. The objective of this study was to validate in a commercial field (15 ha) the effects of drip irrigation system on the water use, yield, and quality of two honeydew melon varieties (green flesh and orange flesh) in the Caborca area. Our results indicate that, with 50 cm of water applied, yields were 2146 to 2802 boxes/ha for green flesh and orange flesh, respectively. The predominant sizes were 4s and 5s with 25% and 38% for green flesh, and 5s and 6s with 42% and 36% for orange flesh. These sizes are the best for the exportation market.

Abstract:

ABSTRACT The use of fertigation as a means of supplying the nutritional needs of crops is a technique widely used among producers. However, it is necessary to improve this technique due, mainly, to the risks of contamination of natural resources. Thus, the objective was to study the productivity and leaf contents of melon nutrients and soil fertility, which presents a high concentration of potassium, when fertigated with doses of nitrogen and potassium in the irrigation water. Five treatments were arranged in randomized blocks with six repetitions. Treatments consisted of combinations of concentrations, in mg L-1, of nitrogen (N) and potassium (K) applied in irrigation water (0-0), (50-0), (50-54), (0-54) and (100-108). The leaf concentrations of nutrients of melon were evaluated at 35 days after planting, and fruit yield and soil fertility at harvest time. The melon cultivated in soil with a high level of K and basal application of 18 kg ha-1 of N in the foundation did not increase production, when fertirrigated with nitrogen and potassium. Although the contents of K, Fe and B varied between the doses of N and K applied, the plants did not have nutritional deficiency. Fertilizer applications in increasing doses contribute to the accumulation of salts in the soil, increasing the risk of salinization.

Abstract. The author proves that organic fertilizers, unlike the mineral ones, are capable of increasing yields over several years; they do not harm the environment and do not pollute the melon crop fields with nitrates. It has been clarified that their introduction is one of the most effective methods of humus conservation and soil fertility enhancement, which means obtaining fuller yields of high-quality melons and gourds. The NIIMESH researchers have developed a combined unit for local application of organic fertilizers for melons and gourds. (Research purpose) Conducting theoretical studies on the substantiation of the configuration of the working tools of a combined unit for local application of organic fertilizers. (Materials and methods) The author has conducted theoretical studies using methods of analytical geometry and theoretical mechanics. (Results and discussion) Analytical dependences have been obtained to determine transverse distances between furrow shapers used for applying organic fertilizers and making an irrigation groove, as well as longitudinal distances between the tractor's rear wheels and the furrow shapers applying organic fertilizers, between the furrow shapers and the fertilizer spreader, and between the fertilizer spreader and the furrow shaper making an irrigation furrow. (Conclusions) It has been determined that transverse distance between the working tools that make furrows for applying organic fertilizers should range between 0.9 and 1.3 metre, transverse distance between the working tools making an irrigation furrow and a furrow for the application of organic fertilizers is 0.45-0.65 metre. The optimal values of longitudinal distances have been found as well: between the tractor's rear wheels and the working tools making furrows for applying fertilizers – no less than 0.21 metre, between the tip of working tools and the fertilizer spreader – no less than 1.5 metre, and between the fertilizer spreader center and the tip of working tools making an irrigation furrow – at least 0.74 metre.

Entretanto, os países importadores requerem um fruto de alta qualidade. A restrição hídrica na fase final do ciclo do meloeiro pode contribuir para o aumento da qualidade dos frutos atualmente produzidos, pois deve possibilitar um aumento no teor de sacarose dos mesmos. O presente trabalho teve como objetivo estudar os efeitos produtivos e qualitativos da restrição hídrica na fase final do ciclo do meloeiro, procurando-se identificar os melhores momentos e intensidades da redução da lâmina de irrigação. O experimento foi conduzido na Estação Experimental da EMBRAPA, em Paraipaba, CE. O delineamento experimental usado foi o de blocos ao acaso, com parcelas subdivididas. Os tratamentos consistiram da combinação de 4 diferentes momentos de redução hídrica (aos 51, 55, 59 e 63 dias após a germinação - DAG) com 4 diferentes intensidades de redução (100, 66, 33 e 0%), perfazendo um total de 16 tratamentos. O momento em que se iniciou a redução hídrica, bem como a intensidade da mesma, não proporcionaram diferenças estatísticas nas seguintes variáveis: produtividade, firmeza de polpa, classificação dos frutos e espessura da polpa. O teor de sólidos solúveis foi alterado significativamente com relação à intensidade da redução hídrica. UNITERMOS: Cucumis melo, estresse hídrico, fruticultura irrigada.

MELON FRUIT PRODUCTION AND QUALITY UNDER HYDRIC REDUCTION 2 ABSTRACT Melon is one of the most important high cash crops ofNortheastern Brazil. About 30% of the region’s production is exported, and then superior quality fruits are required. Most melon growers stop irrigation a few days before harvest in order to improve fruit sugar content. The objective of this study was to evaluate the effects of the water deficit in the last yield stage and fruit quality in order to identify when and how much irrigation depths should be reduced. The experiment was carried out in a 32 by22 marea, in the Vale do Curu Experimental Station, which belongs toEmbrapaTropicalAgroindustryResearchCenter. A split-plot randomized block design was used. Four different irrigation reduction times (at 51, 55, 59, and 63 days after germination), and four irrigation reduction intensities (100%, 66%, 33%, and 0%) were tested, totalizing 16 treatments. The results showed that the onset of irrigation reduction time and reduction intensity did not affect melon yield, pulp consistency, fruit size, and pulp thickness. The fruit brix was significantly affected by irrigation reduction intensity. KEYWORDS: Cucumis melo, water deficit, irrigated fruit production

Abstract:

Among the problems faced by the melon crop in the state of Rio Grande do Norte, northeastern Brazil, the effect of water and soil salinity is considered one of the key factors to limit fruit production and quality. The aim of this work was to study the effects of using irrigation waters with different salinity levels on yield and quality of fruits of the yellow melon hybrid Mandacaru. A randomized complete block design was used with five treatments (irrigation water salt concentrations: 0.54, 1.48, 2.02, 3.03, 3.9 dS m-1) and four replications. The effects of these concentrations were evaluated through, number of marketable fruits per plant, marketable and total fruit yield, average marketable fruit mass, soluble solids content and pulp firmness. Increment in water salinity level negatively influenced crop yield. The 3.9 dS m-1 salinity level caused yield losses of 20.31%, due to the reduction of fruit number per plant. The highest soluble solid content and the highest pulp firmness values were estimated to occur at salinity levels 2.09 and 3.5 dS m-1, respectively.

Four cover crops {alfalfa (Medicago sativa L. `Kansas Common'), hairy vetch (Vicia villosa Roth), Austrian winter pea [Pisum sativum subsp. arvense (L.) Poir], and winter wheat (Triticum aestivum L. `Tam 107')}, alone and in combination with feedlot beef manure at 5 t·ha–1 were evaluated for 2 years to determine whether sufficient N could be supplied solely by winter cover cropping and manure application to produce high-quality muskmelons (Cucumis melo L. `Magnum 45') in an intensive production system using plastic mulch and drip irrigation. Among the legumes, hairy vetch produced the most biomass (8.9 t·ha–1) and accumulated the most N (247 kg·ha–1). Winter wheat produced more biomass (9.8 t·ha–1) than any of the legumes but accumulated the least N (87 kg·ha–1). Melon yields produced using legume cover crops alone were similar to those receiving synthetic N fertilizer at 70 or 100 kg·ha–1. Melons produced on plots with cover crops combined with beef manure did not differ significantly in yield from those produced on plots with only cover crops. Legume cover crops alone, used with plastic mulch and drip irrigation, provided sufficient N for the production of high-quality muskmelons.

Abstract:

The objective of this work was to evaluate physiological and biochemical responses of Pele de sapo melon to different irrigation depths (ID) and bioestimulant rates (BTM) to improve its production efficiency. The experiment was conducted in an experimental field in Juazeiro, BA, Brazil. A randomized block design in split split-plot arrangement was used, with four ID (60, 80, 100, and 120% of crop evapotranspiration – ETc) in the plots; five (BTM) (Stimulate® at 0, 0.6, 1.2, 2.4, and 4.8 L ha-1 applied via irrigation system during the flowering stage and after the fruiting stage) in the subplots; and two crop seasons (hot season, 23 to 39 °C; and cold season, 15 to 30 °C) in the sub-subplots. The plants were under daily drip irrigation and spacing of 2.0 × 0.3 m. The variables evaluated were: gas exchange, water use efficiency, chlorophyll a and b, relative water, sugar, and amino acid contents, and fruit yield. The results showed that the ID of 60% ETc resulted in water deficit, denoted by increases in solute concentrations, whereas the ID of 80% and 100% resulted in plants with good performance for biochemical, physiological, and production parameters in both crop seasons. The hot season, ID of 120% ETc, and BTM of 2.4 L ha-1 are recommended for Pele de sapo melon crops, since they result in the best physiological responses and fruit yields.

Abstract:

The current scenario of increased water scarcity is due to climate change and directly affects food production. It is thus necessary to develop strategies to mitigate the impacts of low water availability. Therefore, the goal of the present study is to evaluate the physiological behaviour of melon cultivars under water stress. The experiment was conducted in a protected environment in the experimental Submedium region of the São Francisco River Valley in the period ranging from October to December. In this study, we used the melon cultivars 'Amarelo' and 'Piel de Sapo'. The experiment was conducted in a randomized block design with three replicates that were subdivided into plots, where the plots were comprised of four irrigation rates (50, 75, 100, and 125% of crop evapotranspiration – CET), subplots were comprised of the two melon cultivars, and sub-subplots were comprised of samplings for physiological analyses (15, 30, and 45 days after transplanting). The parameters evaluated were stomatal conductance, transpiration, net photosynthesis, relationship CI/CA, and accumulated dry matter. Water stress reduced the stomatal conductance, transpiration, net photosynthesis, CI/CA, and accumulated dry matter. 'Piel de Sapo' showed a higher photosynthetic adjustment than 'Amarelo' melon due to the gas exchange behaviour of the former, and it was, therefore, more tolerant to water stress.

Abstract:

Brazilian Northeast region emerges as both producer and exporter relevant of cantaloupe melon to several countries; however, this region is vulnerable to salinization problems due to it is inserted in a semi-arid area. This study aimed to evaluate the biometrics, physiological, production and quality of new cantaloupe melon hybrids cultivated with different saline waters under semi-arid conditions. The experiment was conducted using a drip irrigation system in a split-plot randomized design. The plot was different irrigation water electrical conductivity (ECw) levels: 0.5, 2.0, 3.5, and 5.0 dS m-1, while the subplot was two new cantaloupe melon hybrids: Zielo and SV1044. Plant biometrics (stems and leaves analysis), plant physiology (solutes accumulation and gas exchange in leaves), fruit production (number, weight, and yield), and fruit quality (physical and chemical analysis) were investigated. Stem length, leaf numbers, leaf area, and shoot dry mass decreased when ECw increased from 0.5 to 5.0 dS m-1. Also, there was an increase of Na and Cl concentration and reduction of K concentration in leaves due to ECw increase. Gas exchange reduction, losses in fruit numbers, weight, yield, and in quality were observed with the ECw increase. It is possible to conclude that the ECw increase salinizes the soil and increases Na and Cl concentration in plants causing reduction in gas exchange, in growth, and in fruit production and quality. However, the response of cultivated hybrids regarding salinity may be different, as in our study that the Zielo hybrid was less affected by the increase in ECw.

O experimento foi conduzido na área experimental do Departamento de Engenharia da Universidade Federal de Lavras, Lavras/MG. A cultivar utilizada foi a Vereda, variedade Inodorus, e a irrigação da cultura foi por gotejamento sendo aplicada quatro lâminas, com turno de rega de dois dias. A evapotranspiração da cultura (ETc) foi calculada com base na evaporação do tanque classe A reduzido (ECA) a as lâminas líquidas (LL) aplicadas foram equivalentes a 0,5.LL, 0,75.LL, 1,0.LL e 1,25.LL. Cada parcela foi composta de 3 linhas com oito plantas por linha. Foi considerado planta útil as seis plantas da linha central de cada tratamento. As características avaliadas foram a altura de planta e diâmetro do caule, o peso médio, o diâmetro longitudinal e transversal dos frutos colhidos das plantas úteis de cada tratamento. O peso médio e os diâmetros longitudinal e transversal dos frutos não foram influenciados significativamente pelas lâminas aplicadas, entretanto apresentou tamanho abaixo do exigido pelo mercado. A altura e o diâmetro do caule tendem a ser maior na lâmina de irrigação equivalente a 0,75LL. UNITERMOS: lâmina de irrigação, Cucumis melo L., peso de fruto, LIMA, E.

GROWTH AND PRODUCTION OF MELON CULTIVATED IN GREENHOUSE UNDER DRIP IRRIGATION 2 ABSTRACT The objective of this study was to evaluate the effect of different irrigation depths on melon growing in greenhouse. The experiment was conducted in an experimental area of the Engineering Departament of the Universidade Federal de Lavras, Lavras/MG. Melon (Cucumis melo L., var. Inodorus, cv. Vereda) was drip irrigated, in a two-day interval, with four different depths. Crop evapotranspiration (ETc) was calculated with a reduced class A pan evaporimeter (ECA). Irrigation depths were input using four different fractions of the net depth (LL): 0.5.LL, 0.75 LL, 1.0.LL and 1.25.LL. Each irrigation treatment was applied to three plants rows, each one containing 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: plant height, stem diameter measures, average weight and fruit longidutinal and transversal diameters. Average weight and fruit longidutinal and transversal diameters were not significantly affected by irrigation depth; however, they presented smaller size than the one demanded by the market. Plant height average and stem diameter average measurements showed tendency to be higher on the irrigation depth equivalent to 0.75.LL. KEYWORDS: irrigation depth, Cucumis melo L., fruit weigth.

A.MELON PRODUCTION USING A HYDROPHYLIC POLYMER UNDER DIFFERENT IRRIGATION FREQUENCY AND GREENHOUSE CONDITIONS 2 ABSTRACT The use of soil conditioners represents an alternative to increase the water holding capacity of sandy soils. This research aimed to evaluate the effect of a hydrophilic polymer at different irrigation frequencies on melon production. The melon (Cucumis melo L.) var. Gold Mine was grown on a sandy soil (Quartzpsament) in 3 kg-pots under greenhouse conditions. The experiment was carried out in a 4 x 3 randomized block factorial design. Treatments with commercial hydrophilic polymer at 0, 2, 4 and 8 g per kg of soil were used. The irrigation frequency was 3 daily irrigations and then at 1-day and 2-day intervals. Results showed that adequate level of hydrophilic polymer ranged from 5 to 6 g per kg of soil, and the use of this level allowed a 1-day irrigation interval.

Abstract:

California melon (Cucumis melo) growers commonly apply calcium (Ca) fertilizers during fruit development to increase fruit firmness and improve storage life. Drip-irrigated field trials were conducted in central California in 2005 and 2006 to evaluate the efficacy of this practice on honeydew (C. melo Inodorus group) and muskmelon (C. melo Reticulatus group). In the 2005 honeydew trial, three weekly applications of 10 lb/acre Ca from calcium nitrate (CN), calcium thiosulfate (CTS), or calcium chloride (CC) were injected into the irrigation system during early melon development. In the 2006 muskmelon trial, two applications of 15 lb/acre Ca from CTS or CC were made early, or two applications of CC late, in melon development. The effect of these Ca fertigation treatments on fruit yield, soluble solids concentration, flesh firmness, and Ca concentration were compared with an untreated control receiving no Ca fertigation. Calcium fertigation had no effect on marketable yield, quality, or Ca concentration of honeydew or muskmelon fruit regardless of application timing or Ca source applied. Loss of firmness during either 2 weeks (honeydew) or 1 week (muskmelon) of postharvest storage was unrelated to Ca fertigation treatment and was not correlated with Ca concentration in fruit tissue. We conclude that under conditions representative of the California melon industry, Ca fertigation at typical application rates is ineffective in improving honeydew or muskmelon yield or fruit quality.

Abstract:

Ten “mini” or personal size seedless watermelons were evaluated at three locations: north and central Mississippi and in central Alabama. `Betsy', `Bobbie', `Demi-Sweet', `Extazy', `Mini Yellow', `Petite Treat', `Solitaire', `Valdoria', `Vanessa', and `Wonder' were the cultivars trialed. Seedlings were started, in a greenhouse, four weeks before planting. All locations used drip irrigation and black plastic mulch and were fertilized according to soil testing lab recommendations. A personal size diploid (seeded) variety, `Jenny', was used as the pollinator. One pollinator was planted, and interspaced evenly, for every three triploid plants. Four harvests were made at each location on 7-day intervals. Yields reported are based on 2,074 triploid plants per acre and 1,037 pollinizer plants per acre. Only the triploid yield reported. Plant spacing was 14 ft2 per plant. For total yield (lb/acre) the cultivars `Petite Treat' (27,210), `Valdoria' (25,700), and `Demi-Sweet' (26,400) were among the top producers at each location. `Mini Yellow' was a top producer at all locations averaging 22,480 lb/acre. For total yield (fruit/acre) the cultivars `Valdoria' (3,380), `Petite Treat' (3,470), `Bobbie' (3,470), `Betsy' (3,380), and `Vanessa' (2,740), were among the top producers at each location. For total yield (lb/fruit) `Betsy' (6.9), `Wonder' (6.7), and `Vanessa' (6.1) had the overall lowest individual fruit weights. `Demi-Sweet' had the highest individual fruit weight in central Alabama (10.0) and north Mississippi (8.8). One problem observed was that a number of melons among cultivars were above or below size class. Also determining melon ripeness was a challenge. Melon quality was good. The soluble solids concentration (sweetness) of all melons was excellent. `Demi-Sweet' had the highest incidence of hollowheart. `Wonder' and `Extazy' had no incidences of hollowheart at any location. Rind thickness had no significant differences, however in both locations measured `Mini Yellow' had the thinnest rind. Rind necrosis was not encountered.

Abstract:

Melon is one of the most demanding cucurbits regarding fertilization, requiring knowledge of soils, crop nutritional requirements, time of application, and nutrient use efficiency for proper fertilization. Developing support systems for decision-making for fertilization that considers these variables in nutrient requirement and supply is necessary. The objective of this study was parameterization of a fertilizer recommendation system for melon (Ferticalc-melon) based on nutritional balance. To estimate fertilizer recommendation, the system considers the requirement subsystem (REQ), which includes the demand for nutrients by the plant, and the supply subsystem (SUP), which corresponds to the supply of nutrients through the soil and irrigation water. After determining the REQtotal and SUPtotal, the system calculates the nutrient balances for N, P, K, Ca, Mg, and S, recommending fertilizer application if the balance is negative (SUP < REQ), but not if the balance is positive or zero (SUP ≥ REQ). Simulations were made for different melon types (Yellow, Cantaloupe, Galia and Piel-de-sapo), with expected yield of 45 t ha-1. The system estimated that Galia type was the least demanding in P, while Piel-de-sapo was the most demanding. Cantaloupe was the least demanding for N and Ca, while the Yellow type required less K, Mg, and S. As compared to other fertilizer recommendation methods adopted in Brazil, the Ferticalc system was more dynamic and flexible. Although the system has shown satisfactory results, it needs to be evaluated under field conditions to improve its recommendations.
