|Abstract:||The present investigation was conducted during the kharif season of 1995 at the Instructional-Cum-Research Farm, Department of Horticulture, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra) with a view to find out the optimum dose of fertilizers for F1 hybrid tomato Cv. Rajashree under local conditions. The fertilizer treatments consisted of four levels (0, 200, 250 and 300 kg per hectare) of nitrogen and three levels (0, 200 and 250 kg per hectare) each of phosphorus and potassium. Thus, there were 36 treatment combinations replicated three times in Factorial Randomized Block Design. The results obtained in respect of growth, yield and fruit quality as influenced by various treatments revealed that the increase in growth with different levels of N was linear. The higher dose of nitrogen (300 kg/ha), phosphorus and potassium (250 kg/ha) each increased the growth of plant. The yield attributing characters such as number of fruits, yield of fruits per plant and mean fruit weight were significantly increased by all four levels of nitrogen. However, the maximum being at 250 kg N/ha. The maximum total yields, per plot and per hectare were obtained with 250 kg nitrogen, 250 kg phosphorus and 250 kg potassium per hectare. The maximum fruit yield was recorded when N, P and K were applied in combination at 250:250:250 kg/ha. The fruit quality parameters such as per cent TSS, per cent acidity, ascorbic acid (mg/100 g) , per cent sugars were significantly increased by nitrogen, the better quality fruits were obtained at 250 kg N/ha and 200 kg each of phosphorus and potassium per hectare. The better fruit quality was recorded when N,P and K were applied in combination at 250:200:200 kg/ha. The plant nutrient status in respect of N, P and K was increased with application of respective element but not proportionately. Tomato Cv. Rajashree F1 hybrid showed a better response to N,P and K fertilization. According to benefit : cost ratio, the optimum dose worked out was the combination of 250 kg N, 250 kg P and 250 kg K/ha under the soil and climatic conditions of Rahuri (Western Maharashtra) for F1 hybrid tomato Cv. Rajashree.|
