Abstract
Abstract The field experiment carried out in Al-Muthanna University research station was located at Northeastern of Al-Muthanna province (9 km from the city center) during the winterseason 2014 –2015. To study the effect of four levels of nitrogen three rates of seeds in oat (Avena sativa L.), the treatments were arranged in spilt plot depending on Randomized Complete Block Design (RCBD) with three replications. (Main –plot) was levels of nitrogen (0, 60, 120, 180) kg N. h-1, while (sub-plot) was rates of seeds (100 ,120 ,140) kg h-1. The results showed a significant superiority in the level of fertilizer 180 kg N h-1on the yield traits paniclesm-2 and biological yield (439.0 panicle m-2, 26.73 ton.h-1) respectively, While the 120 kg N h-1 significantly was affected on number of grains/ panicle and seeds yield (73.76 grain/ panicle, 4.732 ton h-1) respectively, there sults showed that rates sowing pointed to superiority the treatment of140 kg seeds h-1andproduced the highest averages ofpaniclesm-2, number of grains/ panicle and biological yield and seeds yield (411.8 panicle m-2, 71.52 grain/ panicle , 4.74 ton. h-1, 27.43 ton. h-1) respectively, While the 120 kg h-1 significantly was affected on 1000 grain (40.07 g), The results of interactions between fertilizer levels and rates sowing significant in all traits.
