Enhancement in growth, yield and quality of tomato (Solanum lycopersicon L.) fruits by application of integrated nutrient management in Agro-Teri region of West Bengal

The present investigation was conducted for two crop cycles during the Rabi season of 2018-19 and 2020-21 to elucidate the effect of integrated nutrient management on tomato growth, yield, quality and storage quality of fruits at field conditions under the Terai region of West Bengal at Departmental Instructional Farm, UBKV, Pundibari, Cooch Behar. It was laid out in randomized block design (RBD) with 14 treatments. The pooled analysis revealed that treatment viz., A8 (½ Recommended NPK + 50 % FYM + 30 % VC + 20 % PM), A10 (½ Recommended NPK + 50 % FYM + 30 % VC + 20 % PM + 50 % NC) and A14 (½ Recommended NPK + 50 % FYM + 30 % VC + 20 % PM + 50 % NC+ PSB) was found most effective to enhance the yield, quality and economic return with 10.66, 8.31 and 10.51 % higher estimated yield from per hectare land, respectively than inorganic nutrient management. Poultry manure and vermicompost found to have positive effects on almost all the parameters. Integrated nutrient management and bio-stimulants both found equally effective for influencing quantitative and quality parameters in open pollinated and hybrid varieties of tomato. Second experiment revealed that characters viz., truss per plant, fruit per plant, lycopene, total sugar, ascorbic acid and shelf life equally influence by variety and bio-stimulants.
