Effect of varieties and nutrient levels on seed yield, oil yield and total nutrient uptake of sesame (Sesamum indicum L.)

Abstract

The experiment was conducted at Research Cum Instructional Farm of IGKV, Raipur, Chhattisgarh, The crop was sown during Kharif season of 2019. The soil condition of experimental field was clay in texture (vertisols). The experiment was laid out in strip plot design with treatments viz. vertical strips consisted three sesame varieties (V1: TKG-22, V2: TKG-308 and V3: JTS-8) and horizontal strip consisted four nutrient levels (N1: 75% RDF, N2: 100% RDF, N3: 125% RDF and N4:150% RDF) with 12 treatment combinations and replicated thrice. The recommended dose of fertilizer (RDF) is 30:30:20:20 N, P2O5, K2O and S kg ha-1, respectively. Result revealed that among the varieties significantly maximum number of capsules plant-1, seeds capsule-1, test weight, seed yield, stover yield, oil content and oil yield were found in variety JTS-8, which was at par with TKG-22 with respect to seeds capsule-1 and stover yield, it was also at par with TKG-308 with respect to oil content. Above parameters were found minimum(except test weight) in variety TKG-308, maximum N, P, S uptake was found in variety JTS-8 and minimum was found in variety TKG-308, while maximum K uptake was found in variety TKG-22 and minimum in JTS-8. In case of nutrient levels highest number of capsules plant-1, seeds capsule-1, test weight, seed yield, stover yield, oil content, oil yield and nutrient uptake (N, P, K and S) were observed with the application of 150% RDF, which was at par with 125% RDF with respect to number of seeds capsule-1, seed yield, stover yield, oil yield. The data from interaction effect of varieties and nutrient levels, the maximum seed yield was obtained with the combination of JTS-8 (V3) + 150% RDF (N4).
