Response of low land rice to different levels of NPK

Abstract

Fertilizer affects the plant growth and development and is necessary for obtaining maximum crop productivity. However, attainment of maximum nutrient use efficiency is dependent on application of major crop nutrient at proper dose further which varies with variation in genotype. A field experiment was carried out at Rajendra agricultural university farm, Bihar, Pusa to assess influence of various NPK levels (40:20:10, 80:40:20 and 120:60:40 kgha-1) on growth, development and yield of four low land Rice varieties (RAU 720-45-42, RAU 83-500, RAU716-420-31 and Radha). The results revealed that the growth, development and yield attributing characters increased significantly with increase in levels of NPK. Best result observed for NPK level 120:60:40 kg/ha which was found significantly superior. So for good growth and yield the use of appropriate doses of fertilizer will significantly improve the field of low land rice.
