The present research project was executed during 2008-2009, to evaluate the effect of Zn, B (micro-nutrients) in combination with N for the tomato grown under high tunnel. Micro-nutrients were purchased from 4B Group of Fertilizers. The experiment was arranged in Completely Randomized Design (CRD) with fifteen treatments with three replications. The parameters on vegetative and reproductive response were recorded and statistically analyzed at 5 % level of significance. The treatment means were compared by DMR test. After the statistical analysis it was found that as compared to control when different dozes of micronutrients were applied by foliar method, the plants showed variations in their heights, no. of leaves, no of flowers, no of fruits, average fruit weight and yield per plant and same case in quality parameters like TSS %age, Vit. C contents and acidity %age. The treatment T14 (Navigator with Zn = 6%, B = 5%, N = 2%) indicated the maximum average values in all parameter among all other treatments revealed the nearly same results except T3 (Boll feed with B = 5%) and T5 (Sugar Mover with B = 6%) respectively.
