Nutrient content as well as uptake of summer sesame as affected by nitrogen, phosphorus and biofertilizers under South Gujarat condition

Abstract

The investigation entitled, “Nutrient content as well as nutrient uptake of summer sesame as affected by nitrogen, phosphorus and biofertilizers under south Gujarat condition” was conducted during summer season of 2016 at College Farm, Navsari Agricultural University, Navsari to study the response of summer sesame to nitrogen, phosphorus and biofertilizers. The different levels of nitrogen viz., N1: 25 kg/ha, N2: 50 kg/ha and N3: 75 kg/ha, different levels of phosphorus P1: 12.5 kg/ha, P2: 25 kg/ha and P3: 37.5 kg/ha and biofertilizers viz., B0: No inoculation and B1: Inoculation with azotobacter and phosphate solubilizing bacteria to summer sesame in eighteen treatment combinations replicated three in factorial randomized block design. Nutrient content (N, P and K) in seed and haulm was non-significant on nitrogen, phosphorus and biofertilizers. Nutrient uptake (N, P and K) by seed and haulm was significantly higher the application of N3: 75 kg/ha and P3: 37.5 kg/ha which was at par with N2: 50 kg/ha and P2: 25 kg/ha. Nutrient uptake (N and P) by seed was significantly highest the B1: Inoculation with azotobacter and PSB, While, the K uptake by seed was non-significant. Nutrient uptake (N, P and K) by haulm was non-significant to B0: No inoculation and B1: Inoculation with azotobacter and PSB.
