Climate change represents the major challenge to Sudan agricultural production, economics and food security. Changes in temperature, rainfalls, water availability, increased outbreak of pest and diseases, land degradation, soil erosion, shrinking of grazing and cultivate areas, ongoing desertification and the other aspects of climate change have direct significant impact on agricultural product...

in order to study physiological characteristics of rainfed bread wheat genotypes, an experiment was conducted with 20 genotypes in a randomized complete block design with 4 replications under rainfed and supplementary irrigation conditions. this experiment was carried out at the dryland agricultural research institute (dari) in maragheh during 2007-2008. to determine growth indices, sampling wa...

in eastern austria, alfalfa is usually grown as a rainfed crop in crop rotations in organic farming systems, where yearto- year rainfall fluctuations cause different levels of drought stress. to identify the suitability of different alfalfa genotypes and drought tolerance indices, 18 contrasting alfalfa genotypes were evaluated under irrigated and rainfed conditions at the research station of t...

rainfed wheat is the main source of staple food for people in the developing countries. various factors contribute to and affect the production of this crop. the aim followed in the present study was to develop a model to estimate rainfed wheat grain yield as based on physico-chemical properties of the soil. therefore, wheat grain yield and soil physico-chemical properties were separately deter...

Data from runoff plots operated over a ®ve year period show that signi®cantly less overland ̄ow is generated with a seasonal no-till ridge system than with contour tillage or straight tillage systems. Seasonal no-till ridge is the optimum system for increasing the availability of water for rainfed agriculture on the dryland soils in the hilly area of Sichuan Province, China. # 2000 Published by...

This paper reviews the key constraints limiting the practice of CA in tropical rainfed agroecologies. It examines evidence from research, and from widespread indigenous practice, that indicates that successful CA systems for tropical smallholders would benefit substantially from the integration of trees. It argues that Conservation Agriculture with Trees (CAWT) addresses a number of the critica...

the main objective in production of any rainfed crop, including barley farming is to increase water productivity along with stability in the production of the rainfed crop through improvement of the agronomic management including limited single irrigation (si) and sowing date (sd). in order to determine optimal si management and limited water allocation scenarios, a field experiment was conduct...
