Abstract

Four irrigation systems, (surface drip, subsurface drip, sprinkler, and leaky pipe) and two methods of fertilizers application (fertigation and broadcasting) were selected in order to determine the proper irriga­tion and fertilization systems for irrigating vegetable crop in new re­claimed land. Crop growth, water use efficiency, and N use efficiency were considered for systems comparisons. Pea was cultivated as an indi­cator plant. Applying N fertilizer through the selected irrigation systems (surface and subsurface drip, sprinkler and leaky pipe) was more efficient than fertilizer broadcasting. Highly significant increase in stem length, branches and pods number per plant, crop yield, and both water and N use efficiency were obtained by fertigated Pea plants. There was a slight increase (statistically not significant) in stem length, branches number per plant, crop yield and both water and N use efficiency under surface drip more than in both sub-surface drip, sprink­lers and leaky pipe.
