Yield Response of Tomato under Different Combination of Manures and Fertilizers

An experiment was carried out on yield response of tomato (Lycopersicon esculentum Mill.) under different combination of manures and fertilizers at Hogladanga village under the Batiaghata upazila of Khulna district during November, 2013 to March, 2014. Thee xperiment was set up in a Randomized Complete Block Design(RCBD) with three replications. The experiment consisted of seven treatments. The treatments were T 1 = Recommended doses of NPK (Urea @ 350 kg ha-1 , TSP @ 250 kg ha-1 , MoP 300 kg ha-1 , respectively), T 2 = cowdung @10 t ha-1 , T 3 = vermicompost @ 10 t ha-1 , T 4 = Trichoderma compost @10 t ha-1 , T 5 = 50 % cowdung + 50 % recommended doses of fertilizer, T 6 = 50 % vermicompost + 50 % recommended doses of fertilizer and T 7 = 50 % Trichoderma compost + 50 % recommended doses of fertilizer. The response on growth and physio-morphological characteristics, yield attributes and yield of tomato were positively and significantly influenced by the application of vermicompost with recommended d o se of NPK and also Trichoderma compost with the recommended dose of NPK. In most cases T 6 (50 % vermicompost + 50 % recommended doses of fertilizer) treatment performed better. However, the maximum yield of tomato(78.02t ha-1)was obtained from the treatmentreceiving50 % vermicompost + 50 % recommended doses of fertilizer and the lowest yield of tomato (42.36 t ha-1) was obtained from treatment T 2 (cowdung @10 t ha-1). The highest benefit cost ratio (BCR) of tomato (3.15) was obtained from application of 50 % vermicompost + 50% recommended doses of fertilizer due to higher yield and market value. So, 50 % vermicompost + 50% recommended doses of fertilizer treatment (T 6) was proved more profitable and sustainable for cultivation of tomato obtaining better yield.
