Effect of micronutrients on growth, flowering and yield of bitter gourd (Momordica charantia) cv. co 1

Abstract

Present investigation was carried out to study the effect of micronutrients along with magnesium on growth, flowering and yield of bitter gourd. Seven treatment combinations involving the micronutrients viz., Zn, Fe, B and Cu and magnesium were imposed with three replications in randomized block design during two seasons viz., August 2016 and January 2017. Results showed that, among the treatments, foliar application of ZnSO4+ FeSO4+ MgSO4 each @ 0.5% at 35 and 45 DAS recorded significantly maximum mean values for morphological and growth parameters like, vine length, number of nodes, total leaf area per plant, leaf area index, physiological and biochemical characters like chlorophyll content and soluble protein, reproductive characters like number of female flowers, sex ratio and fruit set percentage and yield attributes. For days taken to first female flower appearance and nodes to first female flower production, non significant results were obtained.
