Effect of seeding quantity and chemical fertilizer on growth and grain yield of Oats (Avena sativa L.)

Abstract

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.
