Abstract:
An experiment was conducted using inorganic nutrients and organic nutrients i.e. vermicompost and with their combinations in grafted tomato through integrated nutrient management practices. Experimental results revealed that the nutrient concentrations were lower at 30 DAT, increased and achieved highest at 60 DAT and decreased thereafter. But, the K concentration was low at 30 DAT and 60 DAT, increased and achieved highest at 100 DAT. Similarly, the Sulphur concentration was higher at 30 DAT and decreased there after till 100 DAT. In the INM packages the 100 % inorganic nitrogen (T₂) maintained high N, P and Mg concentration in leaf at 30 and 60 DAT and N at 100 DAT. But, 50 % inorganic nitrogen + 50 % organic nitrogen (T₄) maintained high K, Ca and S concentration at 30 and 60 DAT. where as, 75 % inorganic nitrogen + 25 % organic nitrogen (T₃) showed high P, K, Ca and S concentrations at 100 DAT. Among three types of grafted tomatoes, Grafted tomato maintained high N, P and S concentrations than others. Where as, non-grafted tomato plants maintained higher K and Ca concentration and self-grafted tomato maintained higher Mg concentrations.
