Effect of foliar application zinc and boron on vegetative growth characters of okra

Abstract

To know the effect of zinc and boron on crop growth a field experiment was conducted at vegetable research farm, College of Horticulture and Forestry, Pasighat during the rainy season of the year 2019. Two micronutrients (Zinc and Boron) in the form of zinc sulphate and borax were taken in different concentrations (0.5, 1.0 and 1.5%) and applied at 30 and 60 DAS respectively. The results indicated that among different treatments the highest plant height (141.18 cm) at final harvest, Number of nodes per plant (16.26), Inter-nodal length (8.78 cm) and Number of branches per plant (1.93) were recorded the highest with the treatment receiving Borax-1.0% (T5). The least days taken to first flowering (52.77) and fifty per cent flowering (60.13) were also recorded with the same treatment (Borax-1.0%). All the other parameters found significantly lowest under control treatment (T0).
