Abstract:
Potato yields and infestation by P. infestans are related to the supply of potassium. Potassium was applied as soil fertilisation combined with split foliar applications or only as split foliar treatments at a maximum dose of 150 kg/ha K<sub>2</sub>O in both strategies, Lord and Ditta cultivars were used. Additionally, water spraying was included as an alternative treatment in order to maintain uniform moisture in the rows of plants. Plants fertilised with foliar spraying only were more infested than plants fertilised with combined methods. The fertiliser increased the protection impact of copper treatments against P. infestans. This may suggest a possible synergistic effect in reducing the symptoms of the disease, however not always statistically significant in both cultivars. Plants sprayed with water but without soil application of fertiliser showed a statistically significantly higher infestation rate, both in Lord and Ditta cultivars, compared to plants with soil application of fertiliser but without watering.

Abstract:
An experiment was conducted to compare the effect of applying half a dose of a mineral fertiliser combined with a foliar treatment with four biostimulants and two fertilisers in relation to a full dose of a mineral fertiliser. The M.9 rootstock stoolings were sprayed four times during their growth. Each year of the experiment, the height, the diameter, the fresh weight of leaves and the leaf surface area of all stoolings were measured. The efficiency of rootstocks from one mother plant was assessed. Some parameters of physiological processes as well as the content of micro- and macronutrients in the leaves were also assessed. The research results showed that the reduced dose of the mineral fertiliser with foliar treatment did not significantly decrease the growth parameters of the M.9 rootstock stoolings. Some foliar treatments, especially Bioamino Plant and Bispeed, resulted in higher fresh weight and larger leaf area of the stoolings. The treatment with the Bioamino Plant biostimulant and two foliar fertilisers resulted in parameters of the physiological processes of stoolings that were the same as or better than those in the control plants. After the foliar application of two fertilisers, the content of macronutrients in the leaves of the stoolings was usually the same as in the control. The treatment with the biostimulants resulted in a lower content of most macronutrients in the plants (N, K and Ca). The only exception was the higher magnesium content than in the control after the treatment with all biostimulants and the same phosphorus content after the treatment with most of the biostimulants. The Aminoplant and Bispeed biostimulants increased the accumulation of iron in the leaves, whereas the Basfoliar 6-12-6 fertiliser resulted in higher zinc and copper content than in the control plants.

Abstract:
The ability to utilise foliar-applied phosphorus (P) as a strategy to increase the P status and yield of grain crops grown in dryland regions with variable climates is attractive. Several P formulations with varying pH, accompanying cations and adjuvants were tested for their effectiveness as foliar fertilisers for wheat (Triticum aestivum L.) plants, first under controlled and then under field conditions. Experiments under controlled conditions suggested that several formulations with specific chemistries offered promise with respect to wheat fertiliser-P recovery and biomass responses. These formulations were then evaluated in two field experiments, and although wheat grown at the sites showed substantive responses to soil-applied P, there was no significant grain-yield response to foliar-applied P. Following the limited responses to foliar-applied fertiliser in the field, we used an isotopic dilution technique to test the hypothesis that the variation in responses of wheat to foliar addition of P could be explained by a mechanism of substitution, whereby root P uptake is downregulated when P is taken up through the leaves, but this was proven not to be the case. We conclude that foliar P application cannot be used as a tactical fertiliser application to boost grain yield of wheat in dryland regions.

Abstract:
Abstract The aim of this study was to explore the efficiency of foliar potassium fertiliser relative to morphological, physiological and biochemical properties of hybrid long pepper (Capsicum annuum). Pepper plants were grown in a greenhouse and supplied with three sources of foliar potassium fertilisers, i.e., potassium-humate (1 g/L = 1,250 g/ha), potassium sulfate (1 g/L = 1,250 g/ha), and potassium chloride (1 g/L = 1,250 g/ha). Water served as control. The impacts of these treatments on the phytosynthetic parameters (photosynthetic rate, stomatal conductance, intercellular CO2, leaf carotenoids) and chlorophyll a and b, metabolic compounds and nitrogen, phosphorus and potassium were measured. The phytosynthetic parameters significantly improved by different foliar potassium application and the highest level of photosynthetic activity was noted in plants supplied with potassium sulfate, followed by potassium-humate and potassium chloride. Plant biomass accumulation, cholorophyll (a and b), and total yield showed larger increases in plants fertilised with potassium sulfate than those fertilised with potassium-humate; smallest increases occurred with potassium chloride. Concentrations of total sugars, carotenoids, chlorophyll (a and b), and endogenous level of nitrogen, phosphorus, and potassium contents in plants and fruits were possitively influenced by varying sources of potassium. The fruit color parameters and total soluble solid were also significantly increased with all foliar potassium treatments compared with control. Foliar application of potassium sulfate recorded the highest values and significantly increase all anatomical characters for leaf, stem and fruit of pepper plant.

Abstract:
A significant problem in the cultivation of buckwheat is its low yield, therefore, it is relevant to improve the elements of the technology for growing this crop. The purpose of the study was to establish optimal norms and terms for applying mineral fertilisers and foliar dressing with chelated microfertilisers in the forest-steppe conditions of Western Ukraine, in a zone of sufficient moisture to obtain stable and high yields of buckwheat grain. For this purpose, a two-factor experiment was conducted on the experimental fields of the Lviv National Agrarian University on dark grey podzolized light loamy soil, which included fertiliser rates: N20P20K20, P20K20+N20 (foliar dressing), N40P40K40, P40K40+N40 (foliar dressing), N60P60K60, P60K60+N60 (foliar dressing) and foliar dressing: control (without foliar dressing), Vuksal Boron 2.0 l/ha, Intermag Legumes 2.0 l/ha. Research methods: field studies – to determine the interaction of the object of research with weather factors and elements of the fertiliser system; calculation and weight – setting parameters of crop structure indicators and determining buckwheat yield; methods of mathematical statistics – dispersion, correlation, regressive and graphical display of findings. An increase in fertiliser rates from N20P20K20 to N60P60K60 provided an increase in all indicators of the buckwheat crop structure. Without foliar dressing, they reached the following values: the number of first-order branches – 1.56 pcs./plant, the number of inflorescences and flowers – 10.68 and 1,011 pcs, respectively, the number of full-size and undeveloped grains (pcs./plant) – 41.23 and 11.37, the weight of full-size grains – 1.15 g and the weight of 1,000 grains – 28.00 g. The introduction of nitrogen fertilisers in foliar dressing (at the beginning of flowering) has significant advantages over the introduction of nitrogen for pre-sowing cultivation. One of the proofs of this assumption is the increase in the number of grains, their weight, and the weight of 1,000 grains, respectively, from 35.43 pcs., 0.97 g, and 27.37 g (variant with N40P40K40) up to 37.27 pcs., 1.03 g, 27.80 g (variant with P40K40+N40). This trend is typical for all experiment designs. A positive effect of foliar dressing with microfertilisers on the elements of the crop structure was observed. The use of Vuksal Boron 2 l/ha was more effective. The maximum weight of full-size grains was in the variant P60K60+N60 (foliar dressing) + Vuksal Boron 2 l/ha – 1.21 g, while the use of Intermag Legumes 2 l/ha on a similar background of mineral fertilisers provided this indicator at the level of 1.17 g. Studies have established the positive effect of nitrogen application by foliar dressing during the beginning of flowering on the yield level, and buckwheat yield also increased with an increase in the rate of mineral fertiliser application from N20P20K20 to N60P60K60 and under the influence of foliar dressing with microfertilisers. The maximum yield indicator on average for three years of research is obtained in variant P60K60+N60 (foliar dressing) + Vuksal Boron 2.0 l/ha – 2.64 t/ha

Abstract:
Abstract Organic soybean is presently less than 0.1% of total world production partly because of inappropriate fertiliser regime on degraded tropical soils. Therefore, two field trials were carried out during the late cropping seasons (June – November) of 2017 and 2018 to evaluate the agronomic performance of three soybean varieties: TGx 1448-2E, TGx 1835-10E and TGx 1989-9F as affected by foliar organic fertilisers: Arati Baja, Arati Nawoz, DI Grow, and soil applied organic fertiliser (Aleshinloye Grade B), and the control. The experimental design was Randomised Complete Block Design in a 3 × 5 factorial arrangement with three replications. Data were collected on yield attributes and seed yield of soybeans. Significant varietal difference (P < 0.05) in both years was recorded for number and weight of pods and seeds per plant, 100 seed weight, harvest index, and grain yield, except number of seeds per plant in 2018. Fertiliser × Variety interaction effect significantly (P < 0.05) affected above-ground plant weight and pod weight per plant in both years. On average, application of organic fertilisers resulted in grain yield (1.30–2.28 t/ha) comparable with Nigeria’s (0.97 t/ha) and Africa’s (1.37 t/ha) but lower than the world’s (2.85 t/ha) average values. The three foliar fertilisers and soil applied organic fertiliser enhanced seed yield of soybeans and are therefore recommended for soybean cultivation in the tropics.

Abstract:
Nano-fertilisers have only recently been introduced to intensify plant production, and there still remains inadequate scientific knowledge on their plant-related effects. This paper therefore compares the effects of two nano-fertilisers on common sunflower production under field conditions. The benefits arising from the foliar application of micronutrient-based zinc oxide fertiliser were compared with those from the titanium dioxide plant-growth enhancer. Both the zinc oxide (ZnO) and titanium dioxide (TiO2) were delivered by foliar application in nano-size at a concentration of 2.6 mg·L−1. The foliar-applied nanoparticles (NPs) had good crystallinity and a mean size distribution under 30 nm. There were significant differences between these two experimental treatments in the leaf surfaces’ trichomes diversity, ratio, width, and length at the flower-bud development stage. Somewhat surprisingly, our results established that the ZnO-NPs treatment induced generally better sunflower physiological responses, while the TiO2-NPs primarily affected quantitative and nutritional parameters such as oil content and changed sunflower physiology to early maturation. There were no differences detected in titanium or zinc translocation or accumulation in the fully ripe sunflower seeds compared to the experimental controls, and our positive results therefore encourage further nano-fertiliser research.

Abstract:
Reducing the amount of nitrogen (N) fertiliser applied to dairy pastures down to agronomically optimised levels would have positive economic and environmental results. The ability of commercially available optical sensors to estimate biomass yield and foliar-N uptake in pastures was investigated. Vegetative indices (Simple Ratio, SR; Water Index, WI; and Normalised Difference Vegetation Index, NDVI) from two active optical reflectance sensors (N-Sensor, Yara; and Greenseeker, Trimble) were compared with manually measured biomass and N-uptake in above-ground foliage. There were three measurements over time, from pastures that had received different N fertiliser applications rates (0, 10, 20, 40 and 80 kg N/ha). It was found that the sensors were able to detect differences in biomass and foliar N-uptake following defoliation of grazed pastures. The tested optical sensors have the potential to inform a real-time variable rate fertiliser application system. Keywords: pasture, nitrogen, optical sensors

Abstract In order to investigate the influence of biological and chemical fertilisers on morphological traits, yield and yield components of safflower (Carthamus tinctorius L.), a field experiment was conducted in Maragheh (37°23' N; 46°16' E), in north western Iran, for one year in the 2014 growing season. The effect of seven treatments was evaluated: T1 - control (no fertiliser application), T2 - seed inoculation with P biofertiliser (contains phosphate solubilising bacteria; Pantoea agglomerans strain P5 and Pseudomonas putida strain P13), T3 - seed inoculation with N biofertiliser (contains Azotobacter vinelandii strain O4), T4 - foliar application of iron chelate, T5 - soil application of complete NPK, T6: foliar application of manganese chelate, and T7 - foliar application of zinc sulphate. The result showed that although application of N biofertiliser did not have a significant effect on the evaluated traits, P biofertiliser slightly improved grain yield. However, the application of complete NPK fertiliser improved most of the traits, compared to the control and biofertiliser treatment. The best performance was obtained by foliar application of manganese chelate and zinc sulphate. The results showed that micronutrient-deficiencies have to be managed to unlock the potential yield of safflower in semiarid production systems.

Abstract:
The experiment compared the use of a dose of mineral fertilisation reduced by half in a nursery, which was replaced by foliar treatment with biostimulants and fertilisers. The control combination was a full dose of mineral fertilisation without foliar treatments. The half dose of mineral fertiliser applied into the soil decreased its acidity and salinity. At the same time, it decreased the soil content of macro- and micronutrients, except for calcium and iron. In most cases the simultaneous foliar application of the four biostimulants tested in our experiment reduced the content of macronutrients in the leaves of maiden apple trees, except for calcium. On the other hand, it increased the iron (28.2% average) and manganese (24.8% average) levels in the leaves but reduced the levels of zinc (11.8% average) and copper (25% average). The foliar application of two fertilisers increased the leaf contents of phosphorus (12% average) and calcium (9.3% average). One of the fertilisers also increased the leaf contents of potassium, magnesium, and micronutrients.

Abstract:
The effects of foliar applied urea and potassium chloride on the severity of leaf diseases of cereals were investigated in the laboratory, glasshouse and field between 1992 and 1995. Field studies with urea gave inconsistent results with respect to severity of Erysiphe graminis and consistently increased the leaf area affected by Septaria tritici. However, potassium chloride applied as a foliar spray consistently decreased the leaf area of wheat affected by E. graminis and S. trifid compared with equivalent applications of soil applied fertiliser. Disease control was achieved at early stem extension and after flag leaf emergence but yield responses were not detected. Laboratory investigations were undertaken to determine the mechanism by which foliar applied potassium chloride reduced the leaf area affected by E. graminis. The timing of application, within seven days pre or post inoculation, had no consistent effect on the efficacy of the fertiliser. Investigations using polyethylene glycol as a control showed that the percentage leaf area affected declined linearly as the osmotic potential of the solutions were increased. Light microscopy revealed that the germination of spores in solution and on treated leaves was reduced as the osmotic potential of the solutions were increased. Spores which did germinate developed normally but those on leaves treated with solutions of high osmotic potential rarely formed haustoria. This suggested a second mechanism acting inside the leaf. Multiple regression analysis of experimental data indicated that the inhibition of spore germination was the major response reducing the area of the leaf affected. Although the data were not conclusive it appeared that the increase in leaf water potential, following the foliar application of potassium chloride, was involved in the control of E. graminis.

A single field experiment was conducted near Gila Bend, Arizona in 1991 to evaluate the effects of both soil and foliar applied potassium (K) fertilizersto Upland (Gossvpium hirsutum L.) cotton to a soil testing 315 ppm K (high). Soil applied K fertilizer at rates of 0, 75,150, and 225 lbs. K₂O/acre as K₂SO₄ were broadcast and preplant incorporated before listing. Foliar applications were made in all combinations with the various soil applied K treatments and consisted of four applications of 4.6 lbs. K₂O /acre as KNO₃ (10 lbs. KNO₃ /acre) over the first fruiting cycle, by a ground applicator with approximately 25 gallons per acre as carrier. No differences among treatments were detected by any plant growth measurement taken, plant tissue analyses, lint yield or lint quality determinations which were made over this experiment. Conclusions (preliminary) based upon these results indicate that K fertilization was not warranted under the conditions characterized in this single field experiment.

Abstract:
The effects of two applications of foliar sprays made from kelp (Macrocystis intearifolia Bory) on growth of beans (Phaseolus vulgaris L.) under three moisture regimes were investigated. Date of kelp harvest had little effect on plants grown in water excess or deficit conditions, although means for kelp collected in spring tended to be higher. On soils maintained near field capacity, spray made from kelp collected in July resulted in increases in some bean yield components beyond the effects of kelp collected in spring or fall. The effect of storage of liquefied kelp at room temperature was also investigated and found to be soil moisture dependent. Leaf and root weights of plants grown in field capacity and dry soil respectively were lower for plants treated with kelp aged for 118 days compared to plants treated with kelp stored for longer or shorter durations. In wet soil conditions, the effect of sprays on plant height was reduced by storage of the liquefied kelp. Kelp extracts were fractionated by solvent partition. The butanolic fraction was shown to increase significantly many yield variables under wet soil conditions. This fraction had cytokinin-like activity in two bioassay systems, and contained substances co-eluting with isopentenyl adenine and zeatin in column, thin layer, and gas-liquid chromatography systems. Non-significant increases for some plant yield components resulting from application of unfractionated kelp paralleled these increases. A kelp fraction with undefined constituents increased some yield variables of plants grown in field capacity soil, as did a fraction with auxin and gibberellin-like activities in bioassay. The presence of inhibitors in the kelp was indicated by significantly lower pod yields under dry soil conditions, and a reduction in cytokinin-like bioassay activity when increasing amounts of kelp were assayed. The possibility that phytohormone deficits resulting from root stress are ameliorated by some components of the kelp spray is discussed.

Abstract:
Soybean (Glycine max L. Merrill) is a new cash crop for north central and northwestern North Dakota producers. Soils and climate in these new soybean areas differ from those regions where the current fertilizer recommendations were based. Northcentral and northwestern North Dakota is more undulating, drier, cooler, and has differencing soils than eastern North Dakota and Minnesota. A three-year study to evaluate soybean best management practices was conducted during the 2016 to 2018 growing seasons. Each year, the study consisted of two sites and 12 treatments. By design, one site was on acidic (pH < 6) soil while the other was on alkaline (pH > 7.3) soil. Both site treatments were: untreated check, inoculated with rhizobia (B. japonicum L.), broadcast urea (55 kg ha-1), broadcast MAP (monoammonium phosphate, 11-52-0) (110 kg ha-1), in-furrow 10-34-0 (28 L ha-1), in-furrow 6-24-6 (28 L ha-1), foliar 3-18-18 (28 L ha-1) at V5 and R2 growth stages, and foliar 3-18-18 (28 L ha-1) with sulfate (1.1 kg ha-1) at V5 and R2. The acidic sites alone included two treatments of sugar beet (Beta vulgaris L.) waste lime (4.4 Mg ha-1 and 8.8 Mg ha-1). The alkaline sites alone received treatments of iron ortho-ortho-EDDHA (1.8% Fe) (7.1 L ha-1), and sodium (naked- without Fe) ortho-ortho-EDDHA (7.1 L ha-1). Treatments did not impact soybean yield, protein content or oil content at the 95% significance level. Sugar beet waste lime surface applied at planting at rates of 4.4 Mg ha-1 and 8.8 Mg ha-1 increased soil pH to a depth of 10 cm over the course of the growing season.

Abstract:
High-input management practices are often heavily marketed to producers to increase soybean [Glycine max (L) Merr.] yield in already high-yielding environments. Field research was conducted in three locations within 6 states (Arkansas, Iowa, Kentucky, Louisiana, Michigan, and Minnesota) in 2009 to determine the effect of seed treatment, inoculant, foliar fungicide, additional soil fertility beyond state recommendations, foliar fertilizer, increased population over state recommendations, and narrow row spacing on yield. The high-input system (combination of the management practices) yielded higher than standard-input system (University recommended management practices) in only 8 of the 18 locations. Narrow rows, in both the high and standard-input systems, only increased yield in 4 locations. Inoculant did not increase yield at any location. Foliar fertilizer application and seed treatment increased yield in one location each. The additional soil fertility and fungicide application increased yield in two locations each. The increased population increased yields in 3 of the 18 locations; while an additional fungicide application at R5 only increased yield in 1 location. Foliar fertilizers at rates above commercial use did not increase soybean yield in Kentucky in 2008 or 2009. High-input production practices were largely unsuccessful at increasing soybean yield in these studies.

A field trial was conducted at Yuma, Arizona to examine the effect of foliar boron application on fruit yield and quality of Citrus sinensis and C. limon. Boron was applied to 5 year old Citrus sinensis cv. Hamlin and C. limon cv. Rosenberger Lisbon trees at 5 different concentrations (0 ppm, 500 ppm, 1000 ppm, 2000 ppm, 3000 ppm) either before flowering or after flowering. At harvest, fruit yield and quality, and boron concentrations were determined. Foliar application appeared to increase leaf boron concentration (r= 0.50, p= 0.004). Fruit set was increased in Hamlin trees receiving bloom and post bloom applications of boron at the 1000 ppm level. Boron applications had no significant effect on lemon yield in these studies. This fruit set increase in Hamlin accounted for a 35% increase in overall yield relative to control trees. However, there was no significant difference in fruit weight, fruit pH, titratable acidity, peel thickness, juice volume, or soluble solid content of the fruits among treatments. Previous studies indicate that boron influenced in vivo and in vitro pollen germination in many crops. A plausible explanation for increased fruit yield may be that the applied boron was transported to the flowers where it exerted its influence of increased fruit set through an effect on pollen viability and/or pollen tube growth. However, clearly boron supplementation must be performed judiciously to avoid fruit drop from over -application of the element.

Abstract:
The paper investigates the effect of nitrogen fertilisers on the amount of photosynthetic pigments in winter wheat leaves. The research was carried out in the period between 2012 and 2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of investigation: winter wheat cultivars ‘Zentos’ and ‘Ada’. Granular superphosphate (P60) and potassium chloride (K60) fertilisers were spread during sowing, while amonium nitrate (N60) was used in tillering time (BBCH 23–25), after the vegetative growth had resumed. Additionally, the plants were treated with foliar fertiliser urea solution: N30, N40 at booting stage (BBCH 34–36) and N15, N30 at milk ripening stage (BBCH 71–74). After the analysis of the data, it was established that additional fertilization with N30 and N40 fertiliser application rates at later stages of plant development stimulated the accumulation of photosynthetic pigments and prolonged the period of active photosynthesis. Irrespective of treatment with nitrogen fertilisers, genetic properties of the cultivar also had influence on the accumulation of the pigments. Wheat cultivar ‘Zentos’ tended to accumulate larger amounts of pigments. The highest amounts of pigments were found at the beginning of milk ripening stage before additional treatment with N15, N30 fertiliser application rates.

Abstract:
Experiments involving a winter wheat (Triticum aestivum L.) variety ‘Širvinta 1’ were conducted at the Experimental Station of the Aleksandras Stulginskis University during the period 2006–2009 in limnoglacional silty loam on morainne clay loam Cal(ca)ri-Endohypogleyic Luvisol. Winter crops were grown on the background of N150P90K90 mineral fertilization and were additionally foliar-fertilized with amide nitrogen fertilizer, containing different concentrations of amino acids (0.5 %–3.0 %), at a winter wheat booting, heading and milk maturity stages. Experimental evidence showed that solutions with different amino acids concentrations applied for winter wheat fertilization at booting, heading and milk maturity stages increased plant photosynthetic indicators. Chlorophyll a to b ratio in winter wheat leaves significantly increased having applied 0.5–2.5 % amino acids solutions at booting and at milk maturity stages. Plants fertilized with amino acids solutions at booting stage had a possibility to form larger assimilating leaf area. Winter wheat grain yield significantly increased (0.27–0.4 t ha-1) under the effect of amino acids. The highest yield increases were obtained having applied amino acids at booting and heading growth stages. The statistical data analysis (xextr.) evidenced that the highest yield and its quality would be attained with foliar feeding of winter wheat with amino acids fertilizers: at booting stage with 2.4 %, at heading stage with 1.47 %, and milk maturity stage with 1.39 % amino acids solution.

Abstract:
In 2013 and 2014, field experiments involving winter wheat were conducted at Aleksandras Stulginskis University’s Experimental Station on a medium-textured Cal(ca)ri-Epihypogleyic Luvisol. N150P90K120 were applied as the main fertilizers. Additionally, a foliar fertilizer including amide nitrogen, sulphur and magnesium (MgO concentrations ranging from 0.25 % to 2.5 %), (further referred to as magnesium fertilizer), was sprayed at the tillering and booting stages of winter wheat. It was found that magnesium fertilizer foliar-applied at the end of tillering and booting stages tended to increase chlorophyll a and b contents in winter wheat leaves. Chlorophyll a content in leaves significantly increased when the solution with 2.5 % concentration of magnesium had been applied at tillering and when 0.5, 1.0 and 2.5 % concentrations of the solution had been applied at booting stages. Chlorophyll b content in winter wheat leaves was significantly affected by the solutions with 0.5, 1.0 and 2.5 % magnesium concentrations at tillering and by the solutions with 0.5, 1.0, 1.5, 2.0 and 2.5 % magnesium concentrations at booting stages. The highest increase in dry matter content was recorded when 2.5 % MgO solution had been applied at booting stage. A statistically significant correlation was established between the MgO concentrations applied at tillering (r = 0.905*) and booting (r = 0.863*) stages and nitrogen content in winter wheat dry matter.

Abstract:
The article deals with the effect of nitrogen fertilizer on the yield of different cultivars of winter wheat. Field experiments were conducted in 2011–2013 at the Experimental Station of Aleksandras Stulginskis University in carbonate shallow gleyic leached soil, (Calc(ar)i-Epihypogleyic Luvisol). The object of the investigation was winter wheat cultivars ‘Zentos’ and ‘Ada’. In sowing time the wheat was treated with granular superphosphate (P60) and potassium chloride (K60), and in spring, after the vegetative growth had resumed, in tillering time (BBCH 23–15) with ammonium nitrate (N60). Additionally, foliar fertilizer urea solution was used: N30, N40 at booting stage (BBCH 34–36) and N15, N30 at milk ripening stage (BBCH 71–74). It has been established that application of nitrogen fertilizer at booting and milk ripening stages increased the yield of wheat cultivars ‘Zentos’ and ‘Ada’ (0.06–1.74 and 0.41–1.74 t ha–1). The correlation and regression analysis confirmed that wheat grain yield statistically significantly correlated with nitrogen fertilizer application rates. The correlative relationships were very strong (r = 0.983 and r = 0.987). Irrespective of additional fertilization, genetic properties of the cultivars also had influence on the yield.

Abstract:
The long term goal of this research project was to improve control efficiency of Alternaria diseases while reducing fungicide use, by integration of chemical and non-chemical factors. Non-chemical factors were genotype resistance, age-related resistance and fertilizers. The Specific objectives were: 1) To quantify changes in resistance among genotypes and over time in terms of disease development and specific phases of the disease cycle; 2) To quantify the effects of fertilizers applied to the foliage alone, or in combination with a fungicide, on disease development; 3) To quantify the relative contribution of genotype resistance, age-related resistance and fungicide type to the reduction of disease development; 4) To develop a strategy for integration of chemical and non-chemical factors which will achieve optimal disease suppression. The influence of physiological age of cotton plants and of the individual leaves, on disease incidence and on the rate of lesion expansion of A. macrospora was examined on leaves sampled from the field. Both parameters increased with the physiological age of individual leaves but were not affected by the age of the whole plant. The hypothesis that enrichment of the foliage with nitrogen and potassium may enhance host resistance to Alternaria and thus reduce disease severity, was examined for potato and tomato (A. solani ) and for cotton (A. macrospora ). Under controlled environment conditions, application of urea or KNO3 resulted in some reduction in disease development; however, foliar application of both nutrients (8-10 sprays in total) did not affect Alternaria severity in the field. Systemic fungicides against Alternaria (e.g. , tebuconazole and difenoconazole) are more effective than the commonly used protectant fungicides (e.g. mancozeb and chlorothalonil). Concepts for the integration of genotype resistance, age-related resistances and fungicide for the suppression of Alternaria diseases were developed and evaluated. It was found that reduction in host resistance, with age and among genotypes, can be compensated for by adjusting the intensity of fungicide applications, i.e. by increasing the frequency of sprays and by spraying systemic fungicides towards the end of the season. In, moderately resistant cultivars protection can be achieved by spraying at longer intervals than susceptible cultivars. The concepts for integration were evaluated in field trials for cotton, potatoes and tomatoes. By following these concepts it was possible to save up to five sprays out of 8-10 in a growing season.
