Response growth and productivity of cultivars wheat (Triticum aestivum L.) to fertilization by nano and mineral nitrogen

Abstract

The field experiment was carried out at the Agricultural Research Station of Basra University, College of Agriculture in the north of Basra governorate center during the winter season of 2020/2021 to study the response of growth and yield of three cultivars of wheat (IPA99, BANGIL, and JAAD) to nitrogen fertilization from urea exporters at four levels (0, 60, 120, 80) kg ha-1, and Nano-fertilizer at three levels (0, 15, 30) l ha-1. The experiment was applied by randomized complete blocks design (R.C.B.D) by the method of global experiments with three replications. The study results showed that there was no significant difference in all growth components and the yield between two sources of nitrogen fertilizer (urea and Nano) used in the experiment. The cultivars differed significantly in the studied characteristics. JAAD cultivar outperformed the two cultivars, IPA99 and BANGIL, in recording the highest averages of plant dry weight and nitrogen absorbed for all stages of growth, weight of 1000 grains, and grain yield. The increase in nitrogen fertilization level for urea and Nano sources led to an increase in all studied traits.
