The effects of N:P:K rate (200:100:150, 350:200:250 or 500:300:350 kg/ha) on the performance of 4 indeterminate tomato hybrids (Rakshita, Karnataka, Naveen and Sun 7611) were studied in a multi-span greenhouse during 2000-2001 and 2001-2002. In both years, Karnataka registered the greatest fruit diameter (6.97 and 6.98 cm), average fruit weight (83.28 and 83.88 g), fruit yield (2.85 and 3.07 kg/plant), calculated yield (8.55 and 9.21 kg/m²), juice content (58.84 and 62.43%), gross income (94.05 and 101.31 rupees/m²), net income (17.38 and 24.64 rupees/m²) and benefit:cost ratio (1.23 and 1.32), and the lowest cost of cultivation (76.67 rupees/m² in each year). Rakshita exhibited the greatest pulp content (77.46 and 78.73%), total soluble solids (6.07 and 6.27%) and shelf life (6.40 and 6.50 days). Among the fertilizer levels, N:P:K at 350:200:250 kg/ha was superior in terms of fruit diameter, average fruit weight, yield, gross income and benefit:cost ratio. The number of fruits per plant increased with the increase in the rate of NPK. The quality parameters were not significantly affected by the NPK level in both years.
