Yield, nutrient uptake and economics of sesame (Sesamum indicum L.) as influence by integrated nitrogen management under semiarid condition of Rajasthan

摘要

A Field experiment was conducted at S. K. N. College of Agriculture, Jobner (Rajasthan) with an objective to find out the effect of integrated nitrogen management on yield, nutrient uptake and economics of sesame The experiment consisted twelve treatments of integrated nitrogen management (Control (T_2), 100% RDN through urea (T_2), 100% RDN through FYM (T_3), 100% RDN through poultry manure (T_4), 75% RDN through urea + 25% through FYM (T_5), 75% RDN through urea + 25% through poultry manure (T_6),75% RDN through urea + 25% through FYM + Azotobacter (T_3), 75% RDN through urea + 25% through poultry manure + Azotobacter (T_8), 50% RDN through urea + 50% through FYM (T_9), 50% RDN through urea + 50% through poultry manure (T_(10)), 50% RDN through urea + 50% through FYM + Azotobacter (T_(11)), 50% RDN through urea + 50% through poultry manure + Azotobacter (T_(12)) were tested in randomized block design with three replications. Result showed that different treatments of integrated nitrogen management had significant effect on all the yield attributes (number of capsules per plant and seeds per capsule), seed, stalk, biological yield and economics of sesame. The significantly higher values of these parameters were recorded in the treatments, 50% RDN through urea + 50% through poultry manure + Azotobacter (T_(12)), is at par with 50% RDN through urea + 50% through FYM + Azotobacter (T_(11)), 75% RDN through urea + 25% through poultry manure + Azotobacter (T_8), 75% RDN through urea + 25% through FYM + Azotobacter (T_7), and significantly superior to rest of the treatments. Results further showed that net returns and B:C ratio increased significantly due to treatment 50% RDN through urea + 50% PM + Azotobacter (T_(12)) over control.
