Abstract
The objective of the present study was to evaluate the sensitivity of yield and water productivity of wheat crop to the combined effects of applied water and N fertilizer. Field trials were conducted at the Experimental Field of Agricultural College of Aboureyhan, University of Tehran, during three irrigation seasons. The experimental design was a randomized complete block with four replicates. The main plot consisted of four levels of applied water and the sub-plot consisted of three levels of N application. The results of the statistical analysis of variance showed that there was a statistical difference among different treatments of applied water and grain yield at P
