It was evident from a two year experiment that among the combination between vermicompost and boron, the application of minimum dose of boron (B1=10Kg/ha) with maximum dose of vermicompost (V3=20q/ha) i.e. B1V3 application reduced the number of days taken to flowering, 50% of flowering, ripening, 50% of ripening as compared to the other treatments and found superior in increasing the available N, P2O5, K2O, and Organic carbon in soil. The highest fruit yield was recorded with the combined application of 10 kg borax and 20 q vermicompost (1% N)/ha. The same treatment i.e. B1V3, was also found to be superior in increasing the better results regarding most of the parameters. Moreover the application B1V3 increased availability of N, P, K and Organic Carbon, which exerts positive effect on growth, development and yield of tomato.
• Vermicompost not only supplies essential elements to plants but also improves physico-chemical and biological properties of soil.
B deficiency is the most widespread micronutrient deficiency.
Boron improves growth, yield, quality and nutrient content of tomato. The quality of crops is also influenced due to boron and the timely application of boron helps in increasing the size of fruits as well as firmness.
