abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...

research on crop response to deficit irrigation is important to reduce agriculture water use in areas where water is limited resource. using drought resistant landraces with irrigation scheduling based on phenological stages in semi-arid and arid regions may provide an opportunity to optimize irrigation efficiency and water savings in these regions. in order to evaluate of yield and yield compo...

A limited irrigation study involving four cropping systems and evaluating crop rotations was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The were two annual (continuous corn continuous grain sorghum) 2-year (corn-grain sorghum corn-winter wheat). In 2020, yields similar for all rotations, although averaged across past 8 years, greater following wheat than cor...

In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...

Improving water conservation efforts for golf course turf is a constant industry goal. While creeping bentgrass (Agrostis stolonifera L.; CBG) the preferred fairway species throughout most of cool-humid regions, requirements alternative cool-season with better acute drought tolerance at mowing heights (e.g., <0.5 inch) are not well documented. A 2-yr field study compared two irrigation strategi...
