Response of rice genotypes to levels of nitrogen in lowland

Growth and yield of low land rice genotypes differed significantly due to application of different levels of N, P and K. Uptake was remarkably improved with 120 kg N ha⁻¹. Application of incremental doses of N significantly improved the yield attributes resulting in higher grain and straw yield. Genotype IET-16983 was found significantly superior to other rice genotypes except Radha and IET 15848 in increasing the growth and yield attributes. IET-16983 recorded the maximum grains (3.77 t ha⁻¹) and straw (5.30 t ha⁻¹) yield along with improvement in N, P and K uptake.
