Abstract

In order to investigate the effect of deficit irrigation on quantitative and qualitative characteristics of wheat (Triticum asetivum L.) Morvareed cultivar, an experiment with three main treatments including surface drip irrigation (TS), subsurface drip irrigation (TSS) and Furrow irrigation (F), and three submain treatments containing irrigation levels 50 (I1), 75 (I2) and 100 (I3) percent of the plant water requirement was carried out in the research farm of Ardebil Agricultural Research and Training Center in Moghan region during 2016-2017. The experiment was conducted as split plot based on randomized complete blocks design with three replications. The results showed that the highest 1000-grain weight, harvest index and number of tillers per unit area were obtained with 0.05 kg, 42% and 448.56 in I3 and protein content with 9.56% in I1, respectively. Also, the highest grain yield (7122.33 kg ha-1) was obtained from the TS with irrigation level of I3 (no significant difference between I3 and I1) and the highest water productivity based on grain yield with 1.81 kg m-3 was obtained from the treatment of F with I1. The lowest grain yield with 2866.67 kg ha-1 and water productivity based on grain yield with 1.05 kg m-3 were obtained from the F with irrigation levels of I1 and I3, respectively. Therefore, the surface drip (TS) with 75 percent (I2) and 100 percent (I3) of crop water requirement in conditions of water deficiency and no-water-deficiency, respectively can be considered as optimum methods to the wheat production in the Moghan region.
