Title: Effect of Time of Nitrogen Application on Growth and Yield of Two Wheat (Triticum Aestivum) Cultivars
Author: Ali, Ibrahim Elsadig Ibrahim Mohammed
Abstract: A field experiment was conducted during 2004/2005 season at the Experimental Farm, Faculty of Agriculture at Shambat, to study the effect of time of N application on the growth, yield and yield components of two wheat )T. aestivum) cultivars. Four nitrogen treatments were applied as follows: T1: received no nitrogen (Control). T2: received 95.24 Kg N/ha dose at sowing. T3: received 95.24 Kg N/ha dose at flowering. T4: received 95.24 Kg N/ha dose split into two equal halves one half at sowing and the other at flowering. The cultivars used were Wadi ElNeil and Condor. The results showed that the time of nitrogen application significantly affected plant height; number of tillers per plant; number of leaves per plant; leaf area index; flag leaf area and shoot/root ratio. Similarly, the number of spikes per plant; number of spikelets per spike; number of seeds per spike; 1000-seeds weight; grain yield per plant; total grain yield; straw yield and harvest index were significantly affected by time of N application. In this regard, application of N either as full dose at sowing or split into equal halves at sowing and at flowering resulted in better wheat growth and yield. In conclusion, early application of N was found to be crucial for wheat growth and yield and the cultivar Wadi Elneil outperformed cultivar Condor in all growth and yield characters.
