a randomized complete block design with four replications and a split plot arrangement was conducted in 2010, in order to study the effect of limited irrigation on yield and yield component of sweet corn. water levels were (100%, 80%, and 60% replacement of plant water requirement) which served as main plots. subplot was a factorial arrangement of three different sweet corn varieties (merit, ob...

the agricultural regions are running into difficulties, which are restrictive availability of water, successive appearing draughts, and overuse of ground water resources for supplemental water requirements. as a sample which is got from the farm is sent to the laboratory for testing and the laboratory works need devices. hence, conducting farm experiments are expensive and time consuming to opt...

lorestan and khorramabad province has major share in chickpea production region are the one of the largest producer of chickpea (cicer arietinum l.) in iran, chickpea with more cultivation area compare to the other plants, to estimate the chickpea water requirement. the aim of this research was to determine the crop coefficients of chickpea in a research field in lorestan agriculture faculty in...

Using modern irrigation methods such as border irrigation is one way for an optimum usage of water. Potato, for this study, was cultured in a farm located at Kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. The culture potato was the Agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. Tapes were 12 m and the...
