Integrated nitrogen management through organic resources in summer sesame (Sesamum indicum L.)

A field experiment was conducted during summer 2010 at Junagarh to study the effect of different treatments on growth parameters, yield attributes and yield. The results of the experiment revealed that application of FYM 5 t/ha + castor cake 250 kg/ha + Vermicompost 750 kg/ha (T11) appreciably recorded the maximum plant height (94.50) and number of branches/plant (3.10) at different intervals over remaining treatments. In combination of organic sources of nutrient application of FYM 5 t/ha + castor cake 250 kg/ha + Vermicompost 750 kg/ha provided significantly highest number of capsules per plant (66.33), number of seeds per capsule (73.00), seed yield (824kg /ha) and stalk yield (1604 kg/ha) of sesame. The increases with this treatment were by 32.66, 25.86, 25.55 & 30.83 percent respectively, over RDF i.e. 50 kg N + 25 kg P/ha. This treatment was also significantly enhanced oil content (51.54 %) of seed over rest of the treatments applied and was 22.71 percent higher over RDF.
