abstract in order to evaluate the effects of different depths of irrigation by sprinkler irrigation system on water use efficiency (wue) of new early maize cultivar ksc302, an experiments was carried out in karj during 2006 and 2007. experimental design was split plot based on randomized complete blocks with three replications. main plots were three irrigation levels: 75%, 100% and 125% etc (es...
Film mulch has gradually been popularized to increase water availability to crops for improving and stabilizing agricultural production in the semiarid areas of Northwest China. To find more sustainable and economic film mulch methods for alleviating drought stress in semiarid region, it is necessary to test optimum planting methods in same cultivation conditions. A field experiment was conduct...
Shortage of irrigation water is a major problem constraining in agricultural production in arid and semi-arid regions. Deficit irrigation is one way to cope with water scarcity and increase water use efficiency. Determining the optimum applied water based on economic analysis is a major key to the deficit irrigation strategy. In this study, the required equations were derived to determine the o...
the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
To study the effect of cycocel, nitrogen and planting density on nitrogen (N) content, remobilization and use efficiency of Esfahan 14 safflower cultivar, a field experiment was carried out as a factorial split-plot based on randomized complete blocks design with three replications at Research Farm of College of Agriculture, Yasouj University, in summer of 2010. Main plots were the factorial ...
Salinity and water stress reduces the ability of plant to take up water and decrease growth rate, photosynthesis rate (An) and stomatal conductance (gs) of plants. In this study, effects of deficit irrigation with different salinity levels and planting method (in-furrow and on-ridge) as strategies for coping with water and salinity stress on physiologic properties of rapeseed was investigat...
