A study was conducted at Hi-Tech Unit, Department of Horticulture, Rajasthan College of Agriculture, MPUAT, Udaipur to evaluate the effect of different nutrient sources in tomato under Naturally Ventilated Polyhouse. The study comprises eight treatment combinations with four replications under completely randomized design. The present investigation was undertaken with a view to work out the costs and returns from polyhouse grown tomato under low cost naturally ventilated polyhouse conditions. Polyhouse cultivation of tomato is emerging as specialized production technology to overcome biotic and abiotic stresses during off-season and also ensure round the year production of tomato. Application with 50 per cent organic and 50 per cent inorganic fertilizers was found best in terms of economic feasibility in tomato as it produced the highest gross return (Rs. 266200.00/1000 m2 area), net return (Rs. 188420.00) and net return per rupee investment (2.42) and was also found to be superior in terms of good quality produce. These results suggested that the optimum production and net return can be obtained with the integrated application of 50 per cent organic and 50 per cent inorganic fertilizers.
