Abstract

An experiment was conducted during kharif season of 2017 on clay loam soils of Agricultural Research Institute, PJTSAU, Rajendranagar with an aim to find out the optimum dose and time of nitrogen application for semi-dry rice. Observations were recorded at 20 day interval from sowing viz., 20, 40 60 and 80 DAS and at harvest. At all the times of sampling growth parameters like seedling vigour index, plant height, number of tillers m-2, dry matter production, leaf area index were recorded to be highest with application of 160 kg N ha-1 25% each at sowing, 20 DAS, 40 DAS and 60 DAS compared to the other treatments. However, growth recorded with 160 kg in four equal splits was found to be on par with the growth in the treatments having 160 and 140 kg N ha-1 applied at various splits and with application of 120 kg N ha-1 N in 4 equal splits at sowing, 20, 40 and 60 DAS. Observations on growth parameters were found to be the lowest with application with of nitrogen at 120 kg ha-1 N in 3 splits with 12% at sowing, 44% at 40 DAS and 44% at 60 DAS (farmer’s practice).
