| To investigate the effect of different levels of N-fertilizer in diverse-content irrigation and drought-stress on yield and yield components of various hybrids of corn, an experiment has been conducted for two years (2016-2017) as split plot based on a randomized complete block design with four replications at Natural Resource and Agricultural Research Station, Kermanshah Province, Western Iran located in West Eslamabad (63 km west of Kermanshah). The amount of water-requirement has been assigned as main plots in three levels including 100%, 80% and 60% of water-requirement as perfect, moderate- and extreme-stress levels, respectively. Different levels of N-fertilizer (in the form of urea) were determined based on results of soil-experiment consisting of suggested-amount equal to 170 Kg N ha-1, 30% higher than the suggested-amount (221 Kg N ha-1), 30% lower than the suggested-amount (119 Kg N ha-1), as well as corn hybrids (ksc260, ksc500, ksc703) were dedicated as subplots. In normal states, increasing N-fertilizer level of 119 Kg N ha-1 to 221 Kg N ha-1 improved these attributes, however, imposing drought-stress declined. While in stress-drought accompanied with increasing N-fertilizer from 119 Kg N ha-1 to 170 Kg N ha-1 improved these attributes. Meanwhile, the N-fertilizer effect has not been so important. The grain yield of ksc730 hybrid was higher than the others in the normal and moderate-stress, while reaction to N-fertilizer by ksc260 hybrid was better and led to more enhanced yield in the extreme drought-stress particularly accompanied via applying 221 Kg N ha-1. | ||
