Micronutrient study (Zn and B) in okra was carried out at Vegetable Farm of P.G. College, Ghazipur, Uttar Pradesh. Treatment comprised of two foliar spray of Zn (50 and 100 ppm) and Boron (25 and 50 ppm) solely or in their combinations. Thus, a total of 9 treatments including control (water spray) were replicated thrice. Micronutrient sprays were done twice at 30 and 45 days after sowing.The highest values for plant height (66.50cm),total drymatter production (51.30 g), root area (234.34 cm2) and root length density (1486.87 cm/cm3),fruits/plant (24.33), fruit yield (38.22 g/ plant or 102.56 q/ha) were recorded for combination spray of Zn(50ppm) + B(25ppm). This treatment registered 23.18% higher fruit yield over control.
