Abstract
The effects of mineral, organic and biofertilizers on tomato plants “Castle Rock cv” were studied at Kaha Vegetable Research Station, Horticultural Research Institute during the two successive summer seasons of 1997 and 1998. Data included plant contents from N, P, K, fruit yield and its components and the physical and chemical fruit characters. Organic manure with biofertilizers resulted in significant increases in N, P contents of tomato plants as compared with the control (100 NPK recommended) followed by the 25 % and 50 % of the recommended mineral fertilizers. Chicken manure at 15 m3 / fed plus biofertilizers significantly increased early and total yield comparing with 100 % NPK mineral fertilizer.
                Fruit dry matter %, reduced and total sugars contents, N, P content of fruits were increased by applying chicken manure plus biofertilizers followed by  25 % and 50 % from the recommended minerals plus biofertilizers. Thus, it can be recommended that, the 15 m3 / fed chicken manure plus biofertilizers produced high total yield with the best quality of tomato fruits. Similar positive results were acheived by using 25 % and 50 % from the recommended NPK plus biofertilizers.
