South America is considered as the centre of origin of tomato. It was introduced in Indian subcontinent by the Europeans. India is a prime country in vegetable production by occupying the second position next to China and the production level of tomato in the country is next to potato. The production of tomato in India is about 18 million tones from an area of 0.8 million hectares (NHB). The well ripe tomato (per 100 g of edible portion) contains water (94.1%), energy (23 calories), calcium (1.0 g), magnesium (7.0 mg), vitamin A (1000 IU), ascorbic acid (22 mg), thiamin (0.09 mg), riboflavin (0.03 mg) and niacin (0.8 mg). Various nutrients play an important role in enhancing the yield and quality of tomato fruits. Essential macro nutrient (N, P and K) and some micro nutrient such as (B, Cu and Zn) are very important for enzymatic reactions within plant body such as synthesis International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 05 (2019) Journal homepage: http://www.ijcmas.com The experiment was conducted in Horticulture Garden of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur (U.P.) during the year 2016-2017. The experiment was carried out in Factorial Randomized Block Design with sixteen treatments. The treatments were comprised of combination of four levels of both the micronutrients i.e., Boron (0 %, 0.2 %, 0.3 % and 0.4 %) and Zinc (0 %, 0.4 %, 0.5 % and 0.6 %). Overall, there were sixteen treatment combinations randomly allotted to different plots. Maximum plant height was observed with the application of treatment combination Zn3B0 (98.94 cm) at final harvesting followed by Zn3B3 (98.92 cm) and Zn3B2 (98.87 cm). The results showed that the use of Zn and B at specific concentration in the interactive treatment Zn 3 B 3 ) considerably increased total yield up to 520.22q/ha Keywords Boron, Zinc, Micronutrients, Tomato, Fruit yield Accepted: 12 April 2019 Available Online: 10 May 2019 Article Info
