| Abstract | ||
| A field experiment was carried out during the winter agricultural season 2019-2020 at two location (Al-Hamdaniya, Talkef) to study the effect of nitrogen fertilizer, its application dates, and polymer gel on the growth traits of bread wheat (Triticum aestivum L),cultivar Talafar (3), and the RCBD was used. According to the split plots system and with three replications, the experiment included two factors, the first factor, levels of nitrogen fertilizer and its addition times, which are five levels :{ (zero as control treatment), (40 kg N /h: 1/2 when planting +1/2 beginning of Tillers), (40 kg N /h: 1/3 when planting +2/3 beginning of Tillers),(80 kgN /h: 1/2 when planting +1/2 beginning of Tillers) , (80 kg N /h : 1/3 when planting +2/3 beginning of Tillers)} and the second-factor polymer gel in four levels (0, 80, 160 and 240 kg /h) occupied coefficients The nitrogen fertilizer and the application of the main plots in the main plots experiment. The polymer gel levels occupied the sub plots . The results indicate that the levels of nitrogen fertilizer and the dates of its addition achieved a significant increase in most of the growth traits and for both locations, as well as the levels of polymer gel led to a significant increase in most of the growth traits, two study location, and The significant interaction response got all the growth traits except for the number of days until the beginning of flowering for the AL-Hamdaniya location and C.G.R for the Talkef location. | ||
