Abstract:
A field study to evaluate the effect of different combinations of NPK and micronutrients on nutritional status and quality parameters of sesame was conducted at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agriculture University, Sardarkrushinagar during summer 2019. The experiment consisted of four factors each having two levels viz., nitrogen (N1 - 50 kg N ha^-1, N2 - 75 kg N ha^-1), phosphorus (P1 - 25 kg P₂O_­5 ha^-1, P2 - 50 kg P₂O­₅ ha^-1), potassium (K0 - 0 kg K₂O ha^-1, K1 - 30 kg K₂O ha^-1) and micronutrients (M0 - 0 Kg ZnSO₄ + 0 kg FeSO₄, M1 - 10 Kg ZnSO₄ + 10 kg FeSO₄). Total sixteen treatment combinations were laid out in Randomized block design with factorial concept and replicated three times. Results revealed that application of nitrogen, phosphorus, potassium and micronutrients at higher level had a significant influence on the nutrient uptake and protein content in sesame. After harvest of crop, DTPA extractable zinc content in soil was significantly increased with the application of micronutrients over control. At the same time interaction effect between these nutrients were found to be non-significant.
