Optimizing Yield and Nutrients Content in Tomato by Vermicompost Application under Greenhouse Conditions

Optimizing yield and nutrients content in crop production is the high time demand of arable farming. Vermicompost furnishes one of the most promising alternatives to costly chemical fertilizer. Therefore, a greenhouse experiment was conducted at NARC, Islamabad, to investigate the effect of different levels of vermicompost [having C/N=15/1 and 14 Plant Growth Promoting Rhizobacter ia (PGPR)] on growth, yield and nutrients content in hybrid tomato (National Tunnel To-mato-04-08) under greenhouse conditions during Rabi 2015. The data revealed that different rates (0.5 t∙ha-1, 1 t∙ha-1, 1.5 t ∙ha-1 and 2 t∙ha-1) of vermicompost produced varied and significant (P < 0.05) effect on the vegetative growth parameters (shoot length, root length, dry shoot weight and dry root weight), yield parameters (number of fruits per treatment and total yield) recorded at physiological maturity.
