Evapotranspiration (ET) is a vital component in land-atmosphere interactions. In drylands, over 90% of annual rainfall evaporates. The Nile Basin in Africa is about 42% dryland in a region experiencing rapid population growth and development. The relationship of ET with climate, vegetation and land cover in the basin during 2002–2011 is analyzed using thermal-based Simplified Surface Energy Bal...

In most rainfed production areas in Iran, where wheat fallow is common, crop yield and resource sustainability could be improved by changing to more diverse crop rotation. It seems necessary to identify crop cultivars suitable for such diversification. This study was aimed to determine responses of two common bean (Phaseolus vulgaris L.) cultivars with different growth habits (Sayyad as an inde...

The present experiment was conducted in two environments viz. irrigated and rainfed, with three replications randomized block design at Research Area of Cotton Section, Department Genetics & Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana) during Kharif 2021-22. Fifty elite desi cotton (Gossypium arboreum L.) genotypes were grown as experimental materi...

Abstract This study quantifies the impacts of climate change on yields and corresponding economic losses in six relevant crops that account for 65% harvested area Mexico are highly terms consumption value. The results show crop could decrease considerably during this century, especially rainfed management system. Under a high-emission scenario, large reductions expected by end century both irri...

Land evaluation procedure given by FAO for soil site suitability for various land utilization types for rainfed agriculture has been used to assess the land suitability for khasi mandarin orange and pineapple in East Khasi Hills District of Meghalaya. The database on soil and land use/land cover was generated from IRS-P6 remote sensing satellite data, soil survey and laboratory analysis of soil...

in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...

Yield gap analysis provides an essential framework to prioritize research and policy efforts to reduce yield constraints. To identify options for increasing chickpea yield, the SSM-chickpea model was parameterized and evaluated. The model was applied to analyze seed yield at both potential and water limited production levels and subsequently to find the yield gap for nine different locatio...

Little attention has been paid to the diagnosis of deficiencies of micronutrients such as zinc (Zn) and boron (B) and secondary nutrient such as sulphur (S) in rainfed systems. We evaluated Zn, B and S status of 1617 farmers’ fields in 14 districts of the semi-arid tropical India. Results showed that most of the soil samples were low to medium in organic carbon contents. Results also revealed t...
