Title

The Effect of Different Levels of Water Stress in Two Surface and Subsurface Drip Irrigation Systems on Yield and Water Productivity of Maize

Pages

  247-264

Abstract

 Modern irrigation systems are one of the most important factors affecting crop production, water consumption and productivity, but the performance of these systems requires careful consideration. For this purpose, a study on the effect of surface and subsurface drip irrigation systems with different levels of Deficit irrigation on yield, yield components, and water productivity in SC 704 maize, a factorial split design based on randomized complete block design was conducted in the field of Deputy of Soil and Water, Ministry of Agriculture (Karaj) in summer of 2018. The treatments were included %100, %75 and %50 of water requirement in each type of surface and subsurface drip irrigation. A total of 54 irrigation drips were tested. Based on the results, the interaction of stress and irrigation method for plant length was non-significant, and dry plant weight and harvest index were significant at 1% probability level and other traits at 5% probability level. The results also showed that the highest grain yield 22. 33 ton/ha and 22. 31 ton/ha, were obtained from DI=%100 IR and SDI=%100 IR treatments, respectively, which were not significantly different between these treatments. The lowest grain yield was obtained from DI=%50 IR treatment which had a 33% decrease in yield compared to non-stress treatment in surface drip irrigation. The SDI=%50 IR treatment had the highest irrigation water productivity (2. 75 kg/m3) among the other treatments. The water productivity of this treatment increased by %53. 6 compared to the non-stress treatment in subsurface irrigation.
