Abstract:

Field experiment was conducted during 2011-12 to study the response of rice varieties on morpho-physiological and yield under two nitrogen levels 120 kg N ha-1 [N120], 60 kg N ha-1 [N60] as main treatments and twenty six rice genotypes as sub treatments. In the present investigation among the nitrogen treatments application of  120 kg N ha-1 recorded significantly higher values for morpho-physiological parameters such as number of tillers hill-1, SCMR values, photosynthetic rate and also resulted in maximum number of panicles hill-1, number of filled grains hill-1, filled grain percentage, 1000 grain weight and grain yield. Spikelet sterility and number of unfilled grains hill-1 were minimum in this treatment. Among the genotypes, MTU-1001 recorded the maximum grain yield of 5021 kg ha-1 even under application of 60 kg N ha-1. This indicated that maximum yield can be attributed to maximum SCMR values, more photosynthetic rate, more tillers and panicles, more number of grains hill-1, maximum filled grain percentage and minimum spikelet sterility.
