Timing of Nitrogen Application to Enhance Corn (Zea mays , L.) Yields in a Desert Climate

Timing of Nitrogen Application to Enhance Corn (Zea mays , L.) Yields in a Desert Climate Experiments were conducted in two consecutive years to investigate the response of two corn (Zea mays, L.) cultivars, Eperon and Challenger, to timing of N fertilizer in a desert climate. Fertilizer was applied three times (at planting, 6 weeks after sowing (6WAS) and at 9WAS) to give a seasonal total of 180 kg N ha‐1 The N treatments were Nooo (control), NLOH (60 kg N ha‐1 at planting, none at 6WAS and 120 kg N ha‐1 at 9WAS), NLLL (60 kg N ha‐1 at sowing, 6WAS and at 9WAS) and NLOH, (60 kgN ha‐1 at planting, 120 kg N ha‐1 at 6WAS and none at 9WAS). Generally, N ha‐1 was associated with the highest grain and dry matter yields. Plants in N treated plots had significantly larger number of leaves and ear leaf N contents than the control at mid‐silk. High ear leaf N was associated with high leaf area index and dry matter yield. Based on these results, it would appear that the application of 60 kg N ha‐1 at planting, followed by 120 kg N ha at 6WAS (NLHO) is the most suitable for enhancing corn yields in the desert climate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Agronomy and Crop Science Wiley

Abstract

Experiments were conducted in two consecutive years to investigate the response of two corn (Zea mays, L.) cultivars, Eperon and Challenger, to timing of N fertilizer in a desert climate. Fertilizer was applied three times (at planting, 6 weeks after sowing (6WAS) and at 9WAS) to give a seasonal total of 180 kg N ha‐1 The N treatments were Nooo (control), NLOH (60 kg N ha‐1 at planting, none at 6WAS and 120 kg N ha‐1 at 9WAS), NLLL (60 kg N ha‐1 at sowing, 6WAS and at 9WAS) and NLOH, (60 kgN ha‐1 at planting, 120 kg N ha‐1 at 6WAS and none at 9WAS). Generally, N ha‐1 was associated with the highest grain and dry matter yields. Plants in N treated plots had significantly larger number of leaves and ear leaf N contents than the control at mid‐silk. High ear leaf N was associated with high leaf area index and dry matter yield. Based on these results, it would appear that the application of 60 kg N ha‐1 at planting, followed by 120 kg N ha at 6WAS (NLHO) is the most suitable for enhancing corn yields in the desert climate.
