Abstract:
The purpose of the present experiment was to evaluate the effects of fertigation levels and foliar application of micronutrients during the year of 2021. An experiment was conducted in Factorial Randomized Block Design (FRBD) comprising of two factors- fertigation levels (F₁-125%, F₂-100%, F₃-75% of RDF NPK kg ha^-1) and foliar application (M₀ – Water spray, M₁ – Boric acid, M₂ – ZnSO₄, M₃ – FeSO₄) having twelve treatment combinations in three replications. Results showed that, among all treatment combinations (F₁M₁) i.e. 125% RDF (250:125:125 kg/ha NPK) through fertigation and foliar application of boric acid (0.1%) treatment combination was recorded significantly maximum mean values for growth and yield parameters like, vine length, number of branches at all growth stages, leaf area, number of male flowers, number of female flowers, fruit set and significantly minimum values recorded for days to first male flower appears, days to first female flower appears, sex ratio, node at which first female flower appears and yield parameters viz. number of pickings, number of fruits per vine, fruit length, fruit diameter, average fruit weight, fruit yield per vine, fruit yield per plot and yield per ha. Treatment combinations (F₁M₃) i.e. 125% RDF (250:125:125 kg/ha NPK) through fertigation and foliar application of ZnSO₄ (0.5%) gave the maximum value for chlorophyll index of leaves.
