Effect of Nitrogen, Phosphorus and Potassium on Growth, Yield and Quality of Tomato Grown i in Open Condition

The experiment on effect of NPK on growth, yield and quality of tomato (Solanum lycopersicum L.) grown under open condition was conducted at Department of Horticulture, SHIATS, Allahabad, (U.P.) during Rabi season 2014-15. The seedling of cultivar undertaken for research was Hybrid GS-600 and fertilizers applied in the experiment were Urea, SSP and MOP. The experiment was laid out in RBD with 3 replications and 9 treatments. The results revealed that significantly maximum plant height (165.70 cm), number of leaves/plant (114.52) and number of fruit clusters (7.31) were produced in T7 (140:80:60 kg/ha NPK). Number of fruits/ cluster (7.30), number of fruits/plant (52.85), fruit weight (76.41g) and fruit yield/ plant (4.03 kg) and per hectare (0.952 t/ha) were recorded maximum in T5 (120:80:75 kg/ha NPK). Maximum TSS (4.29 °Brix) and shelf life (18.70 days) were recorded in T6 (120:80:90 kg/ha NPK) under Allahabad agro climatic conditions.
