Resumen

This manuscript aims to create large-scale calculations of agro-climatic factors from global climatic data with high granularity-climatic ERA5-Land dataset from the Copernicus Climate Change Service in particular. First, we analyze existing approaches used for agro-climatic factor calculation and formulate a frame for our calculations. Then we describe the design of our methods for calculation and visualization of certain agro-climatic factors. We then run two case studies. Firstly, the case study of Kojčice validates the uncertainty of input data by in-situ sensors. Then, the case study of the Pilsen region presents certain agro-climatic factors calculated for a representative point of the area and visualizes their time-variability in graphs. Maps represent a spatial distribution of the chosen factors for the Pilsen region. The calculated agro-climatic factors are frost dates, frost-free periods, growing degree units, heat stress units, number of growing days, number of optimal growing days, dates of fall nitrogen application, precipitation, evapotranspiration, and runoff sums together as water balance and solar radiation. The algorithms are usable anywhere in the world, especially in temperate and subtropical zones.

Resumen

In the present study, principal component analysis has been applied to agroclimatic variables for delineating India into homogeneous agroclimatic zones for kharif crops. The vaTiates chosen were soil moisture, water need of the crops, number of rainy days and radiation. Spatial variability of some of these factors has been discussed. Vector 1 and vector 2 were obtained for each of the three separate sets of the variates and plotted to obtain grid maps. Through a process of successive superimposition of these maps, agro-climatic zones have been obtained.

Resumen

In this paper a model of assessment the growth dynamics of soybean yield agro-ecological categories was proposed and a generalized characteristic of agro-climatic conditions of soya cultivation productivity in the forest-steppe zone of the Ukraine was performed. Purpose. Soybean is the most common, legume and oilseed crop of our planet. This thermopiles leguminous plant is the short-day plant of the monsoon climate. Subject of the study. Regularities of the agro-climatic conditions influence on the formation of agro-ecological levels of soybean yield. Purpose of the work is to develop a model and assess the impact of agro-climatic conditions on the soybean yield formation and modeling this influence. Methodology. The theoretical basis of the study was to use the basic model of the assessment of agro-climatic resources of crops productivity formation by A.N. Polevoy, based on H.G.Tooming concept about the maximum crop productivity. The model is based on the concepts of four levels of agro-ecological yield categories: potential yield (PY), meteorologically possible yield (MPY), actually possible yield (APY) and yield in the production (YP). Also we will consider the generalized characteristics of cultivation agro-climatic conditions: degree of favoring meteorological conditions of crop cultivation and efficiency of agro-climatic resources use. On the basis of mean annual meteorological and agro-meteorological data, as well as using information on organic and mineral fertilizers application, the formation of different agro-ecological levels of soybean yields in the Ukraine was modeled. Finding. Calculated values allowed us to estimate the dynamics of PY, MPY, APY and YP growth and the course of decadal sums of PAR during the growing season, which were calculated for forest-steppe zone of the Ukraine. The maximum value of PY, MPY, APY, YP growth and PAR sums reached in the eighth decade and are 225.7 g/m2 ∙ dec., 208.9 g/m2 ∙ dec., 126.9 g/m2 ∙ dec., 43.4 g/m2 ∙ dec. and 11.8 kJ/ cm2 ∙ dec. respectively. By the end and PAR sums of the growing season the growths and PAR sums are reducing. Calculated values allowed us to estimate the dynamics of hydrothermal regime of soybeans. Evapotranspiration (E) and evaporation (E0) have a well-defined trend. With increasing air temperature and precipitation the evapotranspiration may increase or decrease. The ratio of evapotranspiration to evaporability (E/E0) characterizes moisture availability of crops and varies from 0.83 relative units to 0.6 relative units by the end of the growing season. On the basis of calculations made the assessment of generalized characteristics of agroclimatic conditions and productivity of soybean cultivation in the forest-steppe zone of the Ukraine. The highest values of grain MPY, grain APY, grain YP observed in forest-steppe areas, the lowest values are typical for areas of Southern Steppe. The highest degree of favoring the meteorological conditions (Km) for soybean cultivation observed in Polesye, the smallest value (Km) is in Southern Steppe. The assessment of the level of agro-climatic resources use efficiency (Kakl) for soybean cultivation showed that the highest value observed in the forest-steppe areas, the lowest value is in Northern Steppe. Conclusions. Thus, using the simulation we evaluated the impact of agro-climatic conditions on the dynamics of agro-ecological yield growth levels of soybean crop and estimated agro-ecological categories of grain yield, as well as estimated degree of favoring agro-climatic conditions for the soybean cultivation in the forest-steppe areas of the Ukraine.

Resumen

This article examines the dynamics of indicators of grain production productivity and climatic bonus in the context of three zones of the Tyumen region: taiga, southern and northern forest-steppe. The results of the analysis of the gross harvest of the main grain crops in the Tyumen region are presented, which characterize a volatile process characterized by sharp interannual differences. Indicators of agro-climatic bonus range within a year with a range of up to 44%. The unstable nature of the dynamics of weather conditions affecting the productivity of grain production is observed in a time series of agro-climatic bonuses related to the Tobolsk region (taiga), which has low grain yields. In the conditions of climate change, the percentage of values of agro-climatic bonus on the time horizon from one year to 35 years varies within 5.41...51,08%. The study of the dynamics of agro-climatic bonus during the period of active vegetation of grain crops (June-July) for the considered grain-producing territories of the Tyumen region is an urgent issue. The paper demonstrates the capabilities of the author’s tool, which allow an expert analyst to implement research and analysis in the form of “structured” information with the receipt of pre-forecast information and the construction of predictive models of the studied complex processes: the dynamics of indicators of agro-climatic bonus and productivity of grain production in the Tyumen region. The authors put forward a concept based on the comparison of the obtained cycles of the studied time series: the yield of grain crops in the Tyumen region and natural and climatic factors affecting them. The identified cycles of agro-climatic bonus and dynamic range of indicators of grain production productivity based on nonlinear dynamics methods can be used in both continuous and discrete analysis and forecasting.

Resumen

All categories of farmers need information to be productive. Such information is on climatic change. This research work seeks to examine climatic change information needs of agro-pastoralists in Southeast, Nigeria. The specific objectives were to ascertain agro- pastoralists ’awareness of climatic change, identity sources of information on climate change, examine areas climatic change information is needed, and to describe agro-pastoralists responses to climatic change information received. Questionnaire was used to elicit information from 120 agro pastoralists purposively selected from their various camps in 3 Southeast States of Nigeria (Imo, Abia and Enugu). Data collected were analyzed descriptively using percentages and presented in frequency tables. Results showed that all the agro pastoralists were aware of climate change as seen in their response such as occurrence of heavy, but erratic rainfall(95.5%), drought occurrence(81.68%), high temperature(64.2%), flooding(87.5%), water shortage(84.2%), crop failures(100%) among others. Sources of information on climatic change were personal experiences, (80%), fellow farmers(75.3%), Miyetti Allah(100%), Hausa radio program(100%) and many more. They need information on livestock diseases, pasture availability, safe places to go, livestock prices, passable/impassable roads, when to sell their animals. To cope, they sell their animals (90.8%), dig water holes/wells, take animals for vaccination, receive training on animal vaccination, buy veterinary drugs and many more.

Resumen

Abstract The objective of the present study was to map the agro-climatic zone for Robusta coffee crop in the Srepok River Basin. In this study, the trends of temperature and precipitation were identified using by the Mann – Kendall non-parametric test, the water deficit was calculated based on the CROPWAT model, and the agro-climatic zones for Robusta coffee crop were mapped using geographic information system (GIS). Results showed that the average annual temperature and the average annual rainfall had increasing trends. In addition, five agro-climatic zones were identified in the study area, including very appropriate, appropriate, neutral, restricted and inappropriate. Most of the territory was classified as Moderately Suitable for Robusta coffee. Suitable areas for the coffee cultivation were found in the east of the basin. Agro-climatic zoning will help managers and farmers improve crop yields effectively, avoid climate risks and maximize local advantages.

Resumen

Following a drastic fall in coffee production, Côte d'Ivoire has made it a priority to revive its coffee-growing industry. This requires the development of regionalized technical itineraries adapted to climate change. To this end, agro-climatic analyzes were carried out using data from 55 rain gauge stations covering the period from 1985 to 2019. This involved cross-referencing the climatic parameters calculated, taking into account the climatic requirements of coffee trees (Robusta and Arabusta) to define homogeneous agro-climatic zones in the forest and pre-forest zones bounded by the 8th parallel north. The results show that 70.47% of the area is suitable for growing Robusta coffee, compared with 11.37% for Arabusta. The mountainous west remains generally favorable to growing both varieties of coffee. The study also updated information on the agro-climatic suitability of coffee-growing areas.

Resumen

In this study,the future simulated climatic data (temperature and rainfall) for the 21st century were downscaled using the regional climate model, viz., PRECIS model (Providing Regional Climates for Impact Studies) for different agro-climatic zones, i.e., Zone II (Ballowal Saunkhri), Zone III (Ludhiana, Amritsar, Patiala and Jalandhar) and Zone V (Bathinda) of Punjab. The corrected simulated data were then analyzed on the annual and seasonal basis to quantify the changes in maximum and minimum temperature and rainfall. The study showed that the maximum and minimum temperature and rainfall by the end of 21st century are likely to increase by 2.0 to 2.2 °C, 3.3 to 5.4 °C and 33 to 66% respectively in agro-climatic zone II; by 0.4 to 5.8 °C, 2.5 to 7.4 °C and 3 to 62% respectively in agro-climatic zone III and by 0.5 to 4.0 °C, 4.7 to 7.7 °C and 58 to 69% respectively in agro-climatic zone V at different locations of Punjab state under various scenarios of climate change. The trend analysis of these parameters revealed there is positive linear increasing trend under different scenarios in the Punjab state.

Resumen

A study was conducted to quantify agro-climatic and agro-ecological zones in north-west India using 34 years (1980-1914) weather data of twenty two agro-meteorological stations of Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh and Rajasthan. The weather data and the coordinates were converted into decimal system for each meteorological station, for spatial analysis. The map of north-west India was digitized and thermal, humidity, rainfall and moisture index and Length of growing period layers were prepared in the GIS environment using Arc GIS 10.1. These layers were combined by union operation and polygons were grouped into different zones. The moisture index and length of growing period zones were integrated with other spatial input layers of soil texture on logical manner to demarcate different agro-climatic and agro-ecological zones and sub zones. Based on texture the soils of study area were broadly characterized in five classes. North-west India was divided into ten agro-climatic zones as Z-1 to Z-10 and thirty six sub agro-ecological zones which represent homogeneity with respect to climate, growing periods and soil texture, which covers all features of abiotic crop environment. These zones helped to adjust cropping season according to moisture, temperature, vegetations and their combination regime. A shift in climatic belt was observed towards south-west as moist sub humid zone in Haryana which did not exist in old climatic map of Haryana. Itwas a new zone noticed in this state. The south-western limit of dry sub humid zone shifted about 40 km and of semi-arid zone shifted to about 60 km. The study will be very useful in the planning of farming system as well as cropping systems and may fill the gaps in ecological zonation of the area.

Resumen

This research examines the transformation of the agro-climatic conditions of the Altai region as a result of climate change. The climate of the Altai region in Russia is sharply continental and characterized by dry air and significant weather variability, both in individual seasons and years. The current study is determined by the lack of detailed area-related analytical generalizations for the territory of the Altai region over the past 30 years. Most of the published data dealing with an integrated analysis of the agro-climatic conditions in the Altai region date back to the late 1960s and early 1970s; in most cases, this data is from climate reference-books based on the generalized data from the first half of the 20th century. To make accurate forecasts and to efficiently manage agricultural production in the Altai region, area-related data on the state and dynamics of agro-climatic changes have been analysed. The results reveal that in the period between 1964 and 2017, significant climatic changes occurred in the territory of the Altai region. These climatic changes affected the growing season length, which increased due to a shift in the dates of the air temperature transition above 10 °C, to earlier dates in spring and to later dates in autumn. Furthermore, the current study also revealed that the foothills of the Altai Mountains are the most moistened parts of the region and the Kulunda lowland is the most arid part. In the Altai region, the accumulated temperatures and amounts of precipitation during the growing season increased significantly, and the values of integrated coefficients and indices that reflect the moisture supply conditions for the territory also changed significantly. Based upon the results, a schematic map of the current precipitation distribution on the Altai region’s territory has been generated. These results and this map may be used to conduct more detailed studies in the field of agro-climatology and to update the current borders of agro-climatic areas and revision of the agro-climatic zonation scheme.

Resumen

This study estimates the impact of major climate variables (temperature and rainfall) on crops’ productivity across four agro-ecological zones of Pakistan. The crops selected were rice, wheat, maize, cotton and sugarcane. The study used panel data from 1991 to 2010 and applied panel least square techniques. The results revealed that the effect of climatic variables on crops yield varied across agro climatic zone due to differences in their climate conditions. Temperature and rainfall were the important determinants affecting crops productivity across agro climatic zones of Pakistan. Wheat productivity has been impacted more in Northern Irrigated Plain-a by average temperature and in Northern Dry Mountains by rainfall than the other zones. Rice productivity has been impacted more in Dry Mountains by average temperature and in the Indus Delta by rainfall than other zones. Sugarcane productivity has been impacted more by average temperature and rainfall in Indus Delta than zone IV. Maize productivity has been impacted more by average temperature and rainfall in Northern Dry Mountains than other zones. Finally the study recommends proper mitigative and adaptative strategies to enhance the positive and lessen the adverse impact of climate change on crops productivity across agro climatic zones of Pakistan.

Resumen

The present study makes an attempt to analyse farm level cost inefficiency of maize farming and its determinants in different agro-climatic regions of Sikkim. The primary data for the study were collected during the third and fourth quarter of 2018 from different agro-climatic regions of Sikkim. Both data envelopment and stochastic frontier analysis were used for measurement of the farm level inefficiency across different agro-climatic regions of the study area. Based on the Cobb–Douglas cost function for maize output, the article simultaneously estimated stochastic frontier cost function and examined the effect of exogenous factors on farm level cost inefficiency. The results of this study showed that, on an average, the farmer incurred cost which was 8 per cent to 72 per cent above the minimum cost defined by the best practice frontier. Further, cost inefficiency was relatively higher among the farmers in temperate agro-climatic region. Greater cost inefficiency seems to be directly associated with remoteness of farmland from input market. The study also found that the additional years of farming experience and farming in the rented plots were useful in reducing cost inefficiency.

Resumen

The paper presents the growth in foodgrain production in different agro-climatic zones of Bihar during the last 30 years (1984 to 2014). There has been growth in production of foodgrains during the period under study, however, maize and wheat recorded the steady growth during the period. Pulses production got setback in all the agro-climatic zones, particularly during 1984-94. Agro-climatic zone II had an edge over other three agro-climatic zones with respect to increase in foodgrain production mainly due to lower foodgrain production during the base year (TE 1984). Foodgrain production got a boost during 2004-14. Instability in production of all foodgrains was high, but higher instabilityin production was observed in rice and lower in wheat.The instability in foodgrain production was mainly due to frequent floods in north Bihar and droughts in south Bihar. Also, the growth and instability had positive relationship across all the zones. However, the sustainable increase in foodgrain production was made possible due to improved farmersâ€™ access to inputs and technology. All the three critical inputs (irrigation, fertilizers and HYV seeds) played a significant role in increasing foodgrain production in Bihar.

Resumen

This study sought to analyze the degree of spatial association of soil texture with agro-climatic zones and slope classes on the farmlands of the Jema watershed, in the Northwestern Highlands of Ethiopia. The agro-climatic zones (elevation zones) determine the micro-climate and biota of the study area. Thirty six soil composite samples for texture (the proportion of clay, silt and sand) analysis from four agro-climatic (elevation) zones and seven slope classes were collected. One-Way-ANOVA was employed to compute the mean variability of texture among the identified terrain classes, and linear regression was used to analyze the degree of association between texture and the terrain attributes. The measured values of sand, silt and clay in the watershed ranged from 11.4 to 43.4, 6.0 to 34.8, and 21.8 to 77.8, respectively. The One-Way-ANOVA indicated a significant (p < 0.05) soil texture variation in both slope and agro-climatic zone classes. Heavy clay, clay and clay loam were identified as the major texture classes in the lower, middle and upper parts of the watershed, respectively. The regression analysis showed that texture was more influenced by the difference in the elevation values than in slope values in the watershed. The standardized beta coefficients of slope and elevation for clay particles were 0.499 and 0.767, respectively. For sand, the regression coefficients for slope and agro-climatic zone were 0.485 and 0.812, respectively. This implies that an interactive effect of micro-climate and biota governed by elevation influenced the spatial distribution of soil texture more than slope.

Resumen

Wide range of inter-annual climatic variability and frequent occurrence of extreme climatic events in Indian context is a great concern. There is a need to assess the impact of these events on agriculture production as well suggest the agri-management options for sustenance. The appropriate region specific agro-advisory needs to be established for the farmers and other stake holders. Crop simulation models are effective tools for assessing the crops’ response to these climate related events and for suggesting suitable adaptation procedures for ensuring higher agricultural production. Remote sensing and GIS are effective tools in this regard to prepare the regional based agro-advisories, by linking with the crop simulation models and relational database layers of bio-physical and socio-economic aspects. For effective agro-advisory services, there is a need to link the other biotic and abiotic stresses for accurate estimates and generating window of suitable agri-management options. Crop simulation models can effectively integrate these stresses for crop and soil processes understanding and ultimate yield formation. In this review article, we have discussed about the inter-annual/ seasonal climatic variability and occurrence of extreme climatic events in India and demonstrated the potential of crop models viz., INFOCROP, WTGROWS, DSSAT to assess the impact of these events (also including climate change) on growth and yield of crops and cropping systems and thereby suggesting appropriate adaptation strategies for sustenance. The potential of remote sensing for crop condition assessment and regional/national yield forecast has been demonstrated. Crop simulation tools coupled with remote sensing inputs through GIS can play an important role in evolving this unique operational platform of designing weather based agro-advisory services for India.

Resumen

The study was conducted to analyse the rainfall pattern of dry farming zones of Southern Karnataka to arrive at proper date of sowing by considering parameters like threshold rainfall (20 mm), threshold dry day (2.5 mm) and threshold dry spell period (10 days) as a main defining parameters for decision making in sowing of major crops (finger millet, pigeonpea, groundnut, etc.). In all the three zones, the agro-climatic onset of cropping season was earlier as compared to meteorological onset (June 1st week) due to bimodal distribution of rainfall having its peaks in May and September month. In Central Dry Zone, Southern Dry Zone and Eastern Dry Zone, fourteenth June, thirteenth June and twentythird May were the agro-climatic onset dates (average of all stations in each zone), respectively. Station wise analysis of the rainfall revealed different agro-climatic onset dates. Ninth May in central dry zone, eighth May in eastern dry zone and fifth May in southern dry zone were the earliest onset dates. These variations in between zonal and station specific onset dates were due to spatio-temporal variations in rainfall. Therefore, advancements in sowing of crops based on the agro-climatic onset should be taken into account for betterment of crop production.

Resumen

With an increasing rate of global warming and unstable climatic conditions concerns with regards to epidemiology of plant viruses are on the rise. Studies suggest accelerating climatic changes shall severely affect the management of pest and diseases in cultivated crops. Tomato Leaf Curl Virus (TLCV) is an economically affecting viral infections of tomato (Lycopersicum esculentum). The disease causes severe yield loss and major economic impairment. The current study was therefore taken up to understand the influence of agro climatic zones on diversity of TLCV in Tomato plants. Samples of TLCV infected Tomato plants exhibiting varying symptoms were collected from seven different agro climatic zones of Gujarat followed by isolation of viral particles, molecular characterization and development of phylogenetic tree. Interestingly the molecular analysis of the isolated viral samples indicated little influence of climatic conditions on the types of TLCV infecting the tomato plants.

Resumen

The study attempts to show the impacts of agro tourism in environmental and climatic betterment of the state and nation. The results of this study will tell us that agro-tourism will help to improve environmental and climatic factors and also plays a great role as an additional income source for farmers and government. General public is now-a-day’s facing problem because of environmental instability and this can be cured if we consider agro tourism sector as a solution and incorporate this sector too like other tourism sector. Maharashtra was the first to understand this sectors demand and used this concept very well to improve its GDP and environment. Agro tourism help to create awareness among public about the environment by providing income source and environmental benefits both simultaneously. It creates knowledge about agriculture science. A modern style of development proposes rationalexploitation of agricultural resources together with the rediscovery of heritage both historical and naturalistic as a means to reach sustainable development. Agro tourism acts as the contact point between the tourist’s expectations of healthy environment, natural and fresh products, rediscovery of nature and best touristic services with an unforgettable experience. The study assumes the importance of environmental and climatic betterment to neutralize or reduce its harmful effects in near future. It helps to evaluate that how a sustainable development can be reached without causing damage to our environment. This synergy between agriculture and tourism capitalized on the combined benefits of development in agriculture as a primary sector and tourism as a service sector which further boost rural employment generation and environmental benefits. Thus, the paper suggests that agro-tourism has the potential for developing income opportunities and creates new ways for environmental and climatic betterment

Resumen

Long climate data information will be very useful for the sustainable agricultural sector in determining physiological processes, growth to plant productivity. The Climate Hazard Group Infrared Precipitation with Station (CHIRPS) data is used as a rainfall database for the latest Oldeman agro-climatic zone mapping in Southeast Sulawesi Province. CHIRPS data for 1981-2021 was processed using the Inverse Distance Weighted and Overlay interpolation methods through the Geographic Information System. The results showed that there were thirteen Oldeman agro-climatic zones in Southeast Sulawesi Province, namely B1 (23,71%), B2 (1,97%), B3 (0,22%), C1 (13,48%), C2 (23,21%), C3 (4,64%), D1 (7,36%), D2 (16,71%), D3 (1,28%), D4 (0,00%), E1 (2,92%), E2 (2,32%), dan E3 (2,18%). Zones B1, B2, and B3 are in the northwest, east, and southeast of the area which are very suitable for cultivating two paddy crops followed by planting various types of secondary crops (palawija) during the dry season. Zones C1, C2, and C3 which stretch from west to east are suitable for one-time planting of paddy and two crops of palawija crops. Zones D1, D2, D3, and D4 are spread from the northwest to the southwest to most areas of Muna Island and Buton Island which are suitable for one short-lived paddy planting and one paddy or palawija crop. The agro-climatic zones E (E1, E2, and E3) in the northwest and southwest are only suitable for one crop of palawija crop, depending on rain. The resulting agro-climate map can be used as a reference for cropping patterns that are suitable for the region of Southeast Sulawesi Province.

Resumen

The present study has been focused to recognize and quantify the drought condition in Bihar Agro-climatic Zone-III, which falls in the drought-prone region of Bihar. The zone covers the whole South Bihar region, comprising of seventeen districts. The drought severity assessment in the study area has been carried out by two methods i.e., the rainfall departure analysis and the probability analysis. The research work has been carried out at a grid level consisting of fifty-five grids. The analysis of work has been further evaluated district-wise and in addition the result has been interpreted for the two agro-climatic zones {zone-iii (a) and zone-iii (b)}. For decades, the area is under the influence of frequent droughts due to uneven distribution of rainfall. The grid forty-seven of Bhagalpur district having maximum drought frequency of once in 1.87 years and also faces a maximum number of sixty-two drought years in the period of 116 years, as resulted from rainfall departure method. The maximum annual rainfall departure of -82.99% was observed for the grid-32 (G-32) of Banka district, during the year 1978-79, with a return period of once in 2.7 years. The probability analysis concludes that the areas influenced by grids 37,42,45, and 47 are drought-prone (probability of 75% mean rainfall being less than 80%). The departure as well as the probability analysis indicates that the grid-47 as drought-prone. This shows the compatibility of the two methods in meteorological drought assessment in general and particularly the most drought severe condition of the grid-47.

Resumen

Abstract The objective of this paper was to compare between agro-climatic zones developed from 10-year interval of weather data from 2005-2014, 20-year interval of weather data from 1995-2014 and the zoning developed by [NORELDIN et al. 2016] using 30-year interval from 1985-2014 in the old cultivated land of Egypt in the Nile Delta and Valley. Monthly means of weather data were calculated for each year, and then monthly values for 10-year and 20-years were calculated for each governorate. Basic Irrigation scheduling model (BISm) was used to calculate reference evapotranspiration (ETo). Analysis of variance was used and the means was separated and ranked using least significant difference test (LSD0.05). Our results showed that agro-climatic zoning using 20-year values of ETo was similar to the zones developed with 30-year values of ETo, with different values of average ETo in each zone. Furthermore, using 10-year values of ETo resulted in higher values of ETo in each zone, compared to 20-year and 30-year ETo values. However, the average value of ETo over the three classifications was close to each other. Thus, depending on the availability of weather data, either zoning can be sufficient to develop agro-climatic zones.

Resumen

Vascular streak dieback (VSD) is one of the main diseases on cocoa. This disease can produce a heavy damage in susceptible plants. Agro-climatic condition influences the VSD disease severity level. A study on the relationship between agro-climatic condition and VSD disease severity was conducted in eight locations which were selected based on difference in agro-climatic conditions including altitude, rainfall, number of wet, and dry months. Randomized complete block design was used consisting of eight agro-climatic conditions as treatments which consisted of 200 trees samples, and scored for VSD intensity. A study was also conducted on the response of cocoa clones with different level of resistance at different altitude at Kendeng Lembu, Jatirono, Sungai Lembu, Banjarsari, and Sumber Asin Plantations. A split plot design was applied consisting of two factors. The first factor was location including Pager Gunung (highland) and Besaran (lowland). The second factor was clone resistance with two levels: PA 191 (resistant) and BL 703 (susceptible). VSD scores and stomatal characteristics (stomata number, stomata diameter, and stomata aperture) were determined. The results of experiment showed that VSD scoring differed significantly between the eight agro-climatic conditions. The highest VSD score occurred in the lowland (Gereng Rejo, Banjarsari Plantation, 38 m asl.), where the average annual rainfall was 2161 mm, with five dry months. Cocoa trees in Sumber Asin (580 m asl.), with the average annual rainfall of 2302 mm and 8.5 wet months/3.5 dry months were mostly free of VSD disease. Altitude was positively correlated with rainfall, and negatively correlated with VSD severity. Number of wet months was negatively correlated with VSD severity. Conversely, number of dry months was positively correlated with VSD. The result indicated that genotype, environment, or their interaction did not significantly affect number and aperture of stomata. Although stomatal diameter was significantly affected by environment, genotypes or their interaction with environment did not influence this character.

Resumen

Aim: To gain maximum crop production from a unit area, soil health is one of the major components. It is determined based on the nutritional availability and other parameters like pH, EC, organic carbon, etc. The reports on soil nutrients help farmers in fertilizer application to optimize the yields. The values of these parameters vary from region, soil type, agro-climatic zones, crop, etc. To maintain soil fertility application of organic source of fertilizer such as, FYM plays an important role. It is not only a good source of nutrients but also increases water-holding capacity, soil organic matter, soil physical properties, etc. The study was conducted with an objective to assess nutrient status of soil and FYM from various agro-climatic regions of Maharashtra. Methodology: Maharashtra state is divided into nine different agro-climatic regions. The study was conducted to understand the region-wise variability in the nutritional composition of both soil and FYM in Maharashtra during the year 2020-21. Samples of soils and dried FYM were collected from farmer’s fields from five agro-climatic regions of Maharashtra i.e., Western Maharashtra, Northern Maharashtra, Marathwada, Vidharbha, and Konkan. The samples were analyzed for various parameters at BAL-Chemical laboratory, BAIF Central Research Station, Urulikanchan. Results: The analysis reports of soil samples revealed that soils of the Western Maharashtra region showed maximum values for N, Fe, Mn, Cu, and Zn whereas, soil samples from the Vidharbha region were having high values for P and K content as compared to other regions. The soil samples from the Konkan region showed low nutrients availability than other regions. The soil pH of different agro-climatic regions ranged from 6.3 to 9.0. Similarly, FYM samples of the Western Maharashtra region showed maximum values for N, P, K, Fe, Mn, and Zn content whereas, samples of the Marathwada region were comparatively low in all nutrients and organic carbon content. PCA biplot of macro and micro elements of soil and FYM nutrients revealed geographical/spatial structuring based on nutrient content.

Resumen

This study describes the Vegetation Condition Index in the near-real-time with help of SPOT based Normalized Difference Vegetation Index (NDVI) for Agro climatic-region of India and gave the development pattern in last six year (2002-2007) over the study area of India using decadal time data set from SPOT satellite sensor for 2002-2007 time periods. The each Agro-climatic region of study, 1°x1° degree in area, part of India agro-climate regions, has been taken for analysis using remote sensing and Geographical Information System (RS and GIS)methods, SPOT satellite sensor NDVI data, and from processed data set (geo-referenced data set), cut out 1°x1° degree of area by preparing a layers representing Agro-climatic region of India as base mapping units (BMU),The results indicated that NDVI index is only water stress over vegetation while VCI is an appropriate index for vegetation pattern monitoring over study area. As satellite observations provide better spatial and temporal coverage, the VCI based system will provide efficient tools for management of the improvement of agricultural planning. This system will serve as a prototype in the other parts of the world where ground observations are limited or not available.

Resumen

Influence of agro-climatic factors on the development of common soybean diseases The article presents the results of the study of the influence of agro-climatic factors on the development of major soybean diseases (varieties Anthracite, Sprytna and Perlyna) during 2016-2019 in terms of commercial crops. The dominance of the pathogens Alternaria, Fusarium, Septoria and bacterial burns among the crops was determined. The connection between the development and spread of soybean diseases and hydrothermal environmental conditions was studied. Keywords: soybean, alternariosis, septoria, fusarium wilt, bacterial burns, disease development, disease prevalence.

Resumen

An important element of climate change is to assess changes in agro-climatic growing conditions of crops and the impact of these changes on their performance. Agriculture is the most vulnerable sector of Ukraine's economy to fluctuations and climate change. Given the inertial nature of agriculture and the dependence of the efficiency on the weather, now need to make timely and adequate solutions to complex problems caused by climate change. Due to the expected increase in air temperature of the Northern Hemisphere food security Ukraine will largely depend on how effectively adapting agriculture to future climate change. This includes advance assessment of the impact of the expected climate change on agro-climatic conditions for growing crops. Potatoes - perennial, herbaceous, plant, but in nature is treated as an annual plant, so that the life cycle, beginning with germination and ending with the formation of bubbles and the formation of mature tubers, is one growing season. Potato is one of the most important crops grown and diversified use in almost all parts of our country. But the main focus areas of potatoes in Polesie and Forest-steppe. We consider the relative performance of the photosynthetic productivity of potato and agro-climatic conditions for growing potatoes for the period 1986 to 2005, and expected their changes calculated by the climate change scenarios A1B and A2 for the period 2011 to 2050 in Eastern and Western Forest-Steppe. We consider the agrometeorological and agro-climatic conditions in which there may be a maximum performance of potato.

Resumen

The climatic data of 32 stations of Uttarkahand and adjoining region were collected and the thematic layers of climatic parameters, annual average temperature and precipitation were generated using the spatial analyst Extension of ARC-View. The grid interpolation was applied to generate the surface of annual average temperature and later it was rectified with Digital Elevation Model (DEM) prepared with ASTER data and employing environmental lapse rate (0.65oC / 100 m). Decision Tree Classifier (DTC) embedded in ENVI image processing software was used for agroclimatic zonation of Uttarakhand by considering climatic parameters of annual average temperature and precipitation. During the process of zonation, the temperature map of Uttarakhand was divided into four thermal regimes 1) <00C, 2) 00C - 100C, 3) 100C - 200C and 4) >200C, thereafter, boundaries of the precipitation distribution (in three regimes 1) < 800 mm, 2) 800-1400 mm, and 3) > 1400 mm) in the state have been overlaid on temperature regimes, which divided entire state of Uttarakhand into twelve Agro-climatic zones.

Resumen

<p>Afghanistan grows wheat on about 2.5 million hectares with an average annual production of about five million tonnes. The local research and development efforts make use of country wide research results to recommend varieties and other technologies. Afghanistan has wide ranging climatic variability and its wheat acreage therefore needs to be delineated into wheat climatic zones. A set of 10 different types of wheat varieties were scored for average number of days to 50% flowering (ADF) at 10 locations to delineate Afghan wheat acreage into homogeneous wheat climatic zones based on ADF values. The results obtained hinted at creating eastern, northern, south western and a highland zone for conducting research and recommending wheat technologies.</p>
