Abstract: The present investigations were undertaken at Tomato Improvement Scheme, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri (Maharashtra) with a view to work out optimum dose of graded fertilizers and number of sprays at different intervals for tomato hybrid. The experiment was laid out in Factorial Randomized Block Design with 27 treatment combinations comprising three graded fertilizers (19:19:19, 30:10:10 and 7:7:42) and number of sprays at different intervals (3 sprays at 30 days, 4 sprays at 25 days and 5 sprays at 20 days) and three fertilizer levels (4 g/lit, 5 g/lit and 6 g/lit). Results revealed that, fertilizer formulation significantly influenced plant growth, fruit yield and quality parameters. Fertilizer formulation 30:10:10 required minimum days to 50 per cent flowering and recorded maximum number of branches per plant, polar and equatorial diameter of fruit. The yield contributing parameters such as average weight of fruit and yield per plant were significantly increased by 30:10:10. The fruit quality parameters such as TSS and acidity (%) were significantly influenced by the treatment. Maximum acidity percentage was observed in formulation 30:10:10, however, maximum TSS was recorded in the formulation 19:19:19. Similarly, factor number of sprays at different intervals significantly influenced plant growth and fruit characters. Growth contributing characters (days to 50% flowering, height and number of branches/plant), fruit characters (size, volume and weight of fruit) and yield contributing characters were significantly highest at 5 sprays at 20 days interval. Fertilizer dose significantly influenced plant growth and fruit characters. Growth contributing characters (days to 50% flowering and height of plant) were significantly superior at fertilizer dose @ 5 g/lit. However, number of branches per plant were highest at 6 g/lit fertilizer dose. Number of fruits per plant, yield per plant as well as per hectare increased significantly with increase in dose of fertilizer. The fruit quality parameters such as TSS (%) and acidity (%) increased with increase in fertilizer dose. The per cent incidence of leaf miner and fruit borer was noticed maximum at lower fertilizer dose. Significant interaction effects of both the factors i.e. fertilizer formulation and number of sprays at different intervals were also observed on growth and quality parameters of tomato. The highest yield per plant and per hectare was recorded at A2B3 i.e. 30:10:10 and 5 sprays at 20 days interval (879.90 q/ha) followed by A1B3 i.e. 19:19:19 and 5 sprays at 20 days interval (784.40 q/ha). Similarly, significant interaction effects of number of sprays at different intervals and fertilizer dose were also observed on growth, yield and quality parameters of tomato. The treatment combination B3C3 i.e. 5 sprays at 20 days interval and 6 g/lit. fertilizer dose was significantly superior in respect of height, number of branches, polar and equatorial diameter, average weight of fruit, yield per plot and yield per hectare. The interactions of factor fertilizer dose and formulation had significant influence on plant growth, fruit yield and quality parameters. The highest fruit yield per hectare was recorded at C1A2 i.e. 4 g/lit of 30:10:10 fertilizer formulation (796.85 q/aha) followed by C3A2 i.e. 6 g/lit. and 30:10:10 (778.33 q/ha). Similarly, significant interaction effects of fertilizer formulation, number of sprays at different intervals and fertilizer doses were also observed on growth, yield and quality parameters of tomato. The highest yield per hectare recorded by treatment combination A1B3C3 i.e. 19:19:19, five sprays at 20 days interval of 6 g/lit. fertilizer dose (917.50 q/ha). Thus, it is concluded that, newly developed tomato hybrid RTH-2 by MPKV, Rahuri show better erformance in respect of yield when applied with graded fertilizer formulation 19:19:19, 5 sprays at 20 days interval with 6 g/lit. (A2B3C3) by foliar means in addition to the recommended dose.
