تأثیرکم آبیاری متناوب بر عملکرد و بهره‌وری آب در ذرت دانه‌ای سینگل کراس-704

 Study and application of modern methods of deficit irrigation on cultivation and production of agricultural plants in order to save water consumption is one of research priorities of agriculture. In this respect for inspecting the effect of intermittent deficit irrigation on yield and water productivity in maize SC-704 a research titled randomized complete block design with 4 irrigation treatment and 3 replications was carried out in 2013 at research farm of Aburaihan College –university of Tehran in Pakdasht city. The results of variance analysis showed that intermittent deficit irrigation had significant effect on characteristics of dry weight of plant, grain yield and water productivity and also for reaching more water productivity and grain yield, there is no need of full irrigation, and through intermittent irrigation with one period of full irrigation and the next round with 85 % of full irrigation until the full growth of the plant (treatment B), maximum yield could be reached.
