Effect of integrated nutrient management on uptake and yield of tomato (Lycopersican esculentum L.) and availability of nutrients in soil

A field experiment was conducted during kharif 2010. The N (24.76, 46.97, 103.76 kg ha⁻¹), P (2.86, 6.18, 17.40 kg ha⁻¹) and K (13.80, 31.20, 61.82 kg ha⁻¹) uptakes by tomato crop at vegetative, flowering and harvest stages respectively, were highest in 75% RDN through fertilizers + 25% RDN through Vermicompost. The fruit yield (84.97 q ha⁻¹) of tomato was highest in 75% RDN through fertilizers + 25% RDN through Vermicompost. The highest available nitrogen of 284.3 and 269.5 kg ha⁻¹ were found at vegetative stage and flowering in 75% RDN through fertilizers + 25% RDN through Vermicompost. The highest available P₂O₅ (48.3, 43.4 and 42.4 kg ha⁻¹) and K₂O (358.6, 350.7 and 332.9 kg ha⁻¹) were recorded in 50% RDN through Vermicompost + 50% RDN through Poultry manure at vegetative, flowering and harvest stage of the crop, respectively.
