Abstract:
Tomato (Solanum lycopersicon) is one of the widely grown vegetable and most important food crops in India. It is rich in minerals, essential amino acids, sugars, dietary fibres, vitamins and organic acids. It is well responsive to fertilizer application and reported to be heavy feeders of nutrients. Supply of balanced nutrients can increase the yield, fruit quality and taste of tomato fruit. A pot experiment was conducted using integrated nutrient management practices in grafted tomato during 2017-2018. The experimental results revealed that the treatment 100% inorganic nitrogen showed highest Nitrogen and potassium recovery and use efficiency compared to 100% organic nitrogen and combination of inorganic and inorganic treatments, whereas combination of organic and inorganic nutrients showed highest phosphorus recovery and use efficiency. The grafted tomato maintained the mean recovery of N, P and K of 66.7, 27.1 and 100.4 per cent compared to 27.1, 11.1 and 50.4 per cent with non-grafted tomato and 21.7, 9.2 and 44.3 per cent with self-grafted tomato respectively. And the mean nutrient use efficiency of N, P and K was 18.2, 37.6 and 30 g dry fruit per g of N, P and K applied compared to 3.92, 28.7 and 6.6 with non-grafted tomato and 2.7, 27.8 and 3.6 with self-grafted tomato respectively. Relative agronomic efficiency of the present study showed that the completely inorganic nitrogen performed better than completely organic nitrogen or any other combinations of organic with inorganic.
