Onion is one of the important vegetable/ spice crop. In view of global economic scenario, India is the second largest producer of onion in the world next only to China and accounts for 16 per cent of the world area and 12 per cent of the total production of onion in the world. An attempt has been made in this study to find out the economics of storage and profitability of storage methods. In all, 96 onion growers, 32 each of small, medium and large size groups were randomly selected from Shevgaon and Pathardi tehsils of Ahmednagar district. The data pertained to the reference year 2011-2012. Percentage of loss during storage period of onion was more in traditional type storage structure as compared to improved or bottom ventilated storage structure. Storage cost of onion was also more for the traditional type storage structures particularly due to high storages losses. Per quintal net price realized was more for stored onion as compared to un stored onion in all the market. Storage cost of onion was also more for the traditional type storage structures particularly due to high storages losses. Per quintal net price realized was more for stored onion as compared to un stored onion in all the market. In study area there were four onion storage structures and considering all, improved type of storage structure was most adopted by the farmers because it is well ventilated with less storage losses.

Investigation was carried out during the year 2011-2012. Fifty Kharif tomato cultivators were selected from Chakur, Gharni, Wadwal, Mohanl and Kadmoli villages of Latur district for the present study. The techniques like mean, percentage, ratio and cost concept of Cost-A, Cost-B and Cost-C were used to analyze the data. The results revealed that per hectare gross returns from Kharif tomato was found to be Rs. 102099.43 net profit was Rs. 26309.71. The output-input ratio was 1.35. The per quintal cost of production in tomato was Rs. 332.60.

Investigation was carried out during the year 2013-14. About 96 Bt-cotton growers were randomly selected from twelve villages of two tehsils of beed district of Maharashtra. Cross sectional data were collected from Bt-cotton grower with the help of pretested schedule by personal interview method. The techniques like mean, percentage, ratio and cost concept of Cost-A, Cost-B and Cost-C were used to analyze the data. The results revealed that per hectare cost of cultivation of Bt-cotton was Rs. 67137.76. Among individual items of expenditure, the share of rental value of land was 31.85 per cent followed by hired human labour (13.79 %), bullock labour (9.21), irrigation (8.17%), seed (7.51%), fertilizers (6.19%), family human labour (5.64 %), manure (5.45%), plant protection (3.75%), machine labour (2.15 %), respectively. Per hectare gross returns and net profit was Rs. 129111.85 and Rs. 61974.09, respectively. Output-input ratio was 1.92.

The paper has reported the difference of yield, market prices and returns of organic tomato production with that of inorganic production in Kolar district. The study revealed that per ha average yield of tomatoes on organic farm (203.76q) was comparatively lower than that of inorganic farm (217.5q). The average per kg market price of organic tomatoes (Rs. 15.28) was found to be higher than that of inorganic tomatoes (Rs. 13.65). The output: input ratio was also higher on organic farms (3.12) compared to inorganic farms (2.76).
