abstract rainwater harvesting (rwh) is one of the most effective water resources management techniques for confrontation with water shortage condition. rwh which is basically known as a traditional method, has been developed rapidly and being used widely in dryland countries throughout the world. rwh is defined as collecting and storing rainwater from nearby catchment and delivering it to plant...

Information on the effect of long-term management on soil nutrients and chemical properties is scanty. We examined the 30-year effect of tillage frequency and cropping sequence combination on dryland soil Olsen-P, K, Ca, Mg, Na, SO4-S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0-120 cm depth and annualized crop yield in the northern Great...

In the Great Plains of North America potential evaporation exceeds precipitation during most months of the year. About 75% of the annual precipitation is received from April through September, and is accompanied by high temperatures and low relative humidity. Dryland agriculture in the Great Plains has depended on wheat production in a wheat-fallow agroecosystem (one crop year followed by a fal...

there is limited knowledge about physiological and biochemical functions of bread wheat and durum wheat genotypes in response to drought stress. to study differences of drought-sensitive bread and durum wheat genotypes to drought stress, this study was conducted under two different irrigation regimes (well-watered and water-stressed treatments) under glasshouse conditions. the experiment was co...

Global crop yields are limited by water and nutrient availability. Soil mulching (with plastic or straw) reduces evaporation, modifies soil temperature and thereby affects crop yields. Reported effects of mulching are sometimes contradictory, likely due to differences in climatic conditions, soil characteristics, crop species, and also water and nitrogen (N) input levels. Here we report on a me...
