| Abstract | ||
| Two field experiments were conducted at Al-Oha Wheat State Farm, Department of Agriculture and Livestock, Al-Ain, United Arab Emirates, during two successive seasons of 1996/1997 and 1997/1998 to study the effect of four seeding rates (90, 120, 150 and 180 kg seeds / ha) as well as four nitrogen levels (80, 120, 160 and 200 kg N / ha) on the productivity of the most popular wheat cultivar in the region, i.e. Mexipak 65. The result obtained could be summarized as follows: 1- Varying seeding rate did not affect the grain yield in both seasons. 2- All the characters in this study were not affected by the different seeding rate except number of spikes / m2, number of grains / spike and spike weight in the second season when the lowest seed rate i.e. 90 kg seeds / ha. gave the highest number of grains / spike and the heaviest spike grain weight and the lowest number of spikes / m2. 3- The effect of nitrogen was pronounced spike length, number of spikelets / spike, flag leaf area, plant height, number of spikes / m2, number of grains / spike and spike grain weight were favourably influenced by the increase of nitrogen level. However, 1000-grain weight decreased only in the second season when the level of nitrogen increased more than 120 kg N / ha. 4- Grain yield significantly increased by increasing nitrogen level up to 160 kg and 200 kg N / ha. in the first and second seasons, respectively. | ||
