| A field experiment conducted at farmer field, Basra-Qurna, during 2016-2017 growing season to study the effect of seed rates 80, 100, and 120 kg.h-1. Besides fertilizes application (120 kg N.h-1), nitrogen and phosphorus combination (120 kg N.h-1 + 30 kg P.h-1), NPK (120 kg N.h-1 + 30 kg P.h-1 + 40 kg K.h-1) and their combinations on growth and grain yield of oats. Results showed that 120 Kg.h-1sowing rate gave plant high and flag leaf area, Panicle number in the square meter, grain number in panicle, grain yield , as they were (118.45 cm, 238.67 Panicle.m-2, 71.88 grain.panicle-1, 5,67 Ton.h-1), respectively. NPK (120 kg N.h-1 + 30 kg P.h-1 + 40 kg K.h-1) treatment showed the highest, as compared to others in terms of plant height, area of flag leaf, panicle number in the square meter, grain number in panicle, 1000 grain weight, and grain yield. These values were (131.11 cm, 282.78 panicle.m-2, 84.33 grain.panicle-1, 28.96 g, 6.13 Ton.h-1) respectively. Combination 120 kg.h-1 and NPK (120 kg N.h-1 + 30 kg P.h-1 + 40 kg K.h-1) recorded the highest panicle number in square meter, grain number in panicle and grain yield, as they were 300.00 Panicle.m-2, 84.72 grain.panicle-1, and 6.13 ton.h-1, respectively.
