this research was conducted at torogh agricultural research station in khorasan-e razavi province to determine the impact of irrigation cutoff at different growth stages and percentage of water use on the yield and water use efficiency (wue) of wheat cultivars using sprinkler irrigation. the study was done from 2006-2008. the experimental design was a randomized complete block design with a str...

The most important factor affecting the yield of agricultural crops is formation an optimal water regime in active soil layer. One main methods carrying out such works sprinkling, since it closest to process natural precipitation. At same time, existing sprinklers do not provide watering lands that meets agro-technological requirements due design features and specifics landscape on which they a...
