Abstract


Investigation was carried out to study the effect of different levels of nitrogen and spacing on the yield characters in roselle. A field trial was conducted in a Factorial Randomized Block Design with five levels of nitrogen (50, 100, 150, 200 and 250 kg ha-1) and three levels of row spacing (60, 90 and 120 cm). The results of the present study revealed that the spacing of 120 75 cm and nitrogen application of 250 kg ha-1 was found to be superior in improving the yield characters like number of flowers plant-1, number of fruits plant-1, yield of fresh and dry calyces plant-1, yield of fresh and dry calyces yield plot-1, yield of fresh and dry calyces ha-1, seed yield and dry matter production.
