Abstract:
A field experiment was carried out during the summer season of 2018-20 at Navsari, Gujarat, to evaluate the effect of integrated nutrient management on growth, yield attributes, yields nutrient uptake and economics on sesamum. Growth and yield attributing characters were significantly higher with application of 125% RDF and remained at pat with 100% RDF. In case of different organic manurial treatments observed plant height and number of capsules per plant were observed significantly higher with bio compost @ 5 t/ha and remained at pat with spraying of 1% banana pseudostem sap at flowering and capsule formation stages. Rate of fertilizers and organic manurial treatments were found no significant differ on oil content. In case of biofertilizer, growth and yield attributes were observed non significant. Seed yield and stover yield were significantly superior with application of 125% RDF and bio compost @ 5 t/ha which remained at par with 100% RDF spraying of 1% banana pseudostem sap at flowering and capsule formation stages. Application of biofertilizers as seed treatment gave significantly highest seed yield and stover yield. Nutrient content (N, P₂O₅, K₂O) were found significantly no differ, but nutrient uptake were recorded statistically highest under 125% RDF, bio compost @ 5 t/ha and Azotobacter & PSB (10 ml each / kg seed). Net return and B:C ratio were recorded maximum under the 125% RDF, bio compost @ 5 t/ha and Azotobacter & PSB (10 ml each / kg seed).
