The research work was carried out to analyse the effects of different organic fertilizers on the growth and yield of tomato plants. Tomato plants were raised and grown in the green house with different combinations of organic fertilizers (cow dung, ground nut cake, biomeal and bone meal). The vegetative growth parameter, reproductive/yield parameters were recorded. Quantitative estimation of photosynthetic pigments and major primary metabolites like protein and sugar were also carried out. From the results of this experiment, it was concluded that the different organic fertilizers showed different effects on the growth and yield of tomato plants. Moreover, among the different organic fertilizers used, cow dung fertilizer was found to be the most suitable fertilizer for tomato which was evident from the results obtained in the project work.
