Abstract:
A field experiment was carried out during summer 2021 in field no. B1 at wetland farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore to find out the influence of foliar nutrients on yield and yield attributes of green gram. The experiment field was geographically located in western agro climatic zone of Tamil Nadu at 11ºN latitude and 77ºE longitude and at an altitude of 426.7 meters above the Mean Sea Level (MSL). The texture of the experimental site was clay loam. The experiment was laid out in randomized block design replicated thrice. The treatment consists of T₁: 2% DAP at peak flowering and pod initiation stage. T₂: 2% 19:19:19 at peak flowering and pod initiation stage. T₃: 1% FFW + 1% EAA + 40 ppm NAA + 1% Coconut water at peak flowering and pod initiation stage. T₄: 2% FFW + 2% EAA + 40 ppm NAA + 2% Coconut water at peak flowering and pod initiation stage. T₅: 1% MAP + 0.5% KCl + 0.5% FeSO₄ + 0.5% ZnSO₄ + 0.5% CaCl₂ + 40 ppm NAA at peak flowering and pod initiation stage. T₆: 2% MAP + 1% KCl + 1% FeSO₄ + 1% ZnSO₄ + 1% CaCl₂ + 40 ppm NAA at peak flowering and pod initiation stage. T₇: Control (Water spray + pulse wonder). T₈: Absolute control. The results revealed foliar application of (T₆) - 2% MAP + 1% KCl + 1% FeSO₄ + 1% ZnSO₄ + 1% CaCl₂ + 40 ppm NAA at peak flowering and pod formation stage recorded higher yield and pod setting percentage and it was 24.70% yield increase over absolute control and which was on par with foliar application of (T₄) - 2% Fermented fish waste + 2% Egg amino acid + 2% coconut water + 40 ppm NAA.
