Effect of Date of Sowing and Nutrient Management in Summer Sesame (Sesamum indicum L.) under South Gujarat Condition

Abstract

A field experiment entitled “Effect of date of sowing and nutrient management in summer sesame (Sesamum indicum L.) under south Gujarat condition” was carried out at College Farm, Navsari Agricultural University, Navsari during summer 2019. The experiment consisting 15 treatment combinations comprising of 3 sowing dates viz. D1: 2nd week of February, D2: 4th week of February, D3: 2nd week of March and 5 nutrient management practices viz. N1: 100% RDN, N2: 100% RDN + Sap (1%), N3: 75% RDN + Sap (1%), N4: 100% RDN + Urea (1%), N5: 75% RDN + Urea (1%) were treated in a split plot design with 4 replications. Amongst sowing dates, crop sown at 2nd week of March (D3) registered significantly higher growth attributes, yield attributes, seed yield (778 kg/ha), stalk yield (1933 kg/ha), oil yield and nutrients uptake by seed and stalk. Amongst nutrient management, crop was fertilized with 100% RDN+1% Urea (N4) observed significantly higher growth attributes, yield attributes, stalk yield (1943 kg/ha), oil yield and nutrients uptake by seed and stalk. Significantly the highest seed yield (791 kg/ha) was recorded with 100% RDN+1% Urea (N4).
