Agricultural intensification has increased crop yields, but at high economic and environmental cost. Harnessing ecosystem services of naturally occurring organisms is a cheaper but under-appreciated approach, because the functional roles of organisms are not linked to crop yields, especially outside the northern temperate zone. Ecosystem services in soil come from earthworms in these cooler and...

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...

this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...

this study was performed to investigate the photosynthetic partitioning pattern of materials to aerial parts of bread wheat in dryland conditions. it was as well to study its relationship with bread wheat resistance and grain yield in drought conditions. seven genotypes including two cultivars (azar2, sardari) and five lines were investigated in a field experiment through a randomized complete ...

the effects of planting date and single irrigation (si) allocation scenarios on increasing and stability of yield were investigated to determine the total water productivity and economical water productivity (wpe), for rainfed wheat at dryland agricultural research institute in maragheh, iran, during 2000-2004. the treatments included three sowing dates (early, normal and late), four allocation...

Response of Physiological and Biochemical Characteristics Aseman Wheat Cultivar to Foliar Application Zinc Iron Micronutrient in Dryland Conditions

Grain β-glucan content is the most important attribute for barley (Hordeum vulgare L.) varieties destined for the human food market. This trait is important because of the blood glucose and cholesterol-reducing properties of β-glucans. High levels of grain protein content, test weight, and seed size and endosperm color may also add value. Seed yield potential, in part, determines the economic f...
