A field experiment was carried out to study the effect of foliar application of micronutrients on growth and yield of tomato (Megha) during 2005-06 and 2006-07 at the All India Co- Ordinated Vegetable Improvement Project (AICVIP) in the University of Agricultural Sciences, Dharwad. The results based on two years mean revealed that out of nine different treatments, the application of boric acid @ of 100ppm resulted in maximum number of primary branches (18.30), yield per plant (2.07kg) and fruit yield (30.50 t/ha). Followed by best treatment was the mixture of micronutrients (Bo, Zn, Mn and Fe@ 100ppm and Mo@ 50ppm) recording fruit yield of 27.98 t/ha and differed significantly from the control as well as other treatments. The maximum benefit ratio of 1.80 was obtained with application of boron recording Rs 97,850 /ha of net returns followed by mixture of micronutrients (1.74) recording  Rs 88,900 /ha net returns compared to control (1.40) which recorded minimum net returns of Rs 53,250 /ha.
