A field experiment on impact of organic manures and bio - fertilizers on growth, flowering, fruiting, yield and quality of tomato (cv. Abinash-2) was conducted at Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur) in 2014-15. Four different source of nutrient supply i.e. (I) inorganic N,P, K fertilizers (100: 50: 50 kg/ha), (II) FYM @ 15 t/ha (III) Vermicompost @ 6 t/ha, and (IV) Mustard cake @ 1 t/ha along with three set of bio-fertilizers viz., (i) PSB @ 2 kg/ha, (ii) Azosperillum @ 5 kg/ha and (iii) PSB 2 kg / ha + Azosperillum 5 kg /ha were applied in 12 combinations into the soil. The experiment was laid out in Factorial Randomized Block Design. Best results in terms of fruit yield and quality was obtained with application of vermicompost @ 6 t/ha along with PSB 2 kg/ha and Azospirillum 5 kg/ha. Use of inorganic fertilizers produced significantly lower yield than the best treatment consisting of vermicompost and the two bio-fertilizers in a combination.
