Productivity of Sesame (Sesamum indicum L.) as Influenced by Ratios and Levels of Nitrogen and Phosphorus During Summer

摘要

Field experiment was conducted during summer season 2013 to know the productivity of sesame (Sesamum indicum L.) to ratios and levels of nitrogen and phosphorus during summer. The treatment receiving N/P fertilizer ratio of 1.60 with the split application of nitrogen resulted in significantly higher seed, stalk yield and harvest index (2037,4339 kg ha 1 and 32.04 respectively) over treatment receiving N/P fertilizer ratio of 1.60 without split application of nitrogen and other treatments. Further itwas observed that the split application of nitrogen in the treatments which received other N/P fertilizer ratios (0.78,2.80,2.40 and 2.00) also increased the seed yield of sesame over the basal application only.
