The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...

Questions as to whether public investment in international agricultural research is a ‘Good Thing’ or not may best be addressed using two arguments: (1) justifications based on whether or not past investments have yielded substantial benefits to societies and the resource-poor; and (2) that future investments need to be made as effectively and efficiently as possible, which means they must be t...

low cereal and legumes yields and their rwp index are mainly due to poor distribution of rainfall and poor agronomic management practices. rainfed barley yield and rain water productivity (rwp, defined as rainfed grain yield divided by the total crop season annual rainfall water) in the dry farming are considerable by topography and latitude. yield data, rainfall, altitude and latitude of 182 p...

Understanding the relationships between climatic variables and soil physical and chemical properties with crop yields on large scales is critical for evaluating crop productivity to make better assessments of local and regional food security, policy, land and water resource allocation, and management decisions. In this study, ordinary least squares (OLS) regression models were developed to pred...
