Maximizing yield and water use efficiency of wheat crop using drip irrigation systems

Rapid urbanization and industrialization have increased the pressure on limited existing fresh water to meet the growing needs for food production. To immediate responses to this challenge is the efficient use of irrigation technology. Drip irrigation methods may play an important role in efficient use of water but there is still limited information on their use on wheat crops. An experiment was conducted in Split-split plot design to evaluate the effects of irrigation method under different lateral and emitter spacing on wheat yield, and irrigation water use efficiency (IWUE). The irrigation methods investigated were surface drip, subsurface drip and check basin irrigation. The highest wheat yield (64.31 qha-1 ) and IWUE (1.58 q/ha-cm) was obtained using treatment combination surface drip irrigation and 60 cm lateral spacing with 20 cm emitter spacing and the lowest yield of wheat crop (31.46 qha-1 ) and irrigation water use efficiency (0.52 q/hacm) was obtained using check basin irrigation method. In subsurface drip irrigation highest yield and IWUE in wheat yield production (50.70 qha-1 and 1.25 q/ha-cm) in 60 cm lateral spacing with 20 cm emitter spacing. Using surface drip irrigation with 60 cm lateral spacing with 20 cm emitter spacing can save 32.96 % of irrigation water with increasing yield of wheat crop. | Maximizing yield and water use efficiency of wheat crop using drip irrigation systems
