Abstract:
The field experiment on kharif sesame was conducted at College of Agriculture, Pune during kharif, 2018. The experiment was laid out in split plot design with four fertilizer levels as main plot treatments viz., (50:00:00, 50:10:10, 50:15:15 and 50:20:20NPK kg ha^-1) and four sulphur levels as subplot treatments viz., 0 kg S ha-1, 10 kg S ha-1, 20 kg S ha-1 and 30 kg S ha-1 in variety AKT-101. There were sixteen treatment combinations replicated three times. The soil was clayey in texture with pH 7.7 indicating slightly alkaline in reaction. The results revealed that significantly more seed yield (kg ha^-1) and straw yield (kg ha^-1) was recorded by sulphur level 30 kg ha^-1 than rest of the sulphur level under study. However, it was at par with sulphur 20 kg ha^-1. The fertilizer level F₄ 50:20:20 NPK kg ha^-1 have maximum straw yield plant^-1, seed yield kg ha^-1 at harvest with the same level of sulphur S₄ 30 kg ha^-1. It was revealed from the uptake of N, P and K in seed and straw was significantly influenced by different sulphur levels. Significantly higher uptake of N, P and K were recorded with application of sulphur 30 kg ha^-1 than rest of the treatments. It was revealed from the data of available nitrogen, phosphorus and potassium was significantly influenced by different fertilizer levels. The application of fertilizer dose 50:20:20 NPK kg ha^-1 recorded the lowest available nitrogen, phosphorus and potassium in soil after harvest of sesame. Application of sulphur 30 kg ha^-1 recorded the lowest available nitrogen, phosphorus and potassium in soil after harvest of sesame.
