Investigating Changes inYield and Water Productivity in Different Maize Hybrids (KSC 704 and KSC 410) Under Irrigation Management Using Strip Drip and furrow Irrigation Methods

Correct cultivar choice of corn and provide an efficient irrigation method to save water and increase production per unit area and the optimal use of water resources is very important. This study was carried out to investigating changes in yield and water productivity in different maize hybrids (KSC 704 and KSC 410) under irrigation management using strip drip and furrow Irrigation methods during two years of 2015-2016 in Jopar research station in Kerman province. The experiment was arranged in a split-plot design over randomized complete block design. The results showed that maize hybrids had significant effect on yield and its components at 1% level. The highest grain yield was observed in KSC 704 (13385 kg/ha) compared to KSC 410. The strip drip irrigation method had the highest grain yield (13376 kg/ha) compared to furrow irrigation method. The effect of interaction between irrigation method and maize hybrids showed that the strip drip irrigation method with maize hybrids, KSC 704 recorded higher yield (14128.5 kg/ha.), and an 11% increase in yield compared to maize KSC 410. Also, the lowest amount of irrigation water was 6765 m3/ha and was observed in KSC 410 under strip drip irrigation method. Strip drip irrigation method reduced water irrigation by 33.5% and 36.25% in KSC 704 and KSC 410 treatments, respectively. Also, the water productivity in the strip drip irrigation and farrow irrigation method was equal 1.84 and 0.98 kg/m3 under water storage condition. To increase water productivity and reduce irrigation water, farmers can benefit from drip irrigation due to the profitability of this irrigation method.
