Evaluation of Nutrient Balance and Nutrition use Efficiency on Red Gram (Cajanus cajan) under Various Foliar Feeding

AIM: To assess the nutrient balance and nutrient use efficiency on red gram.

Place and Duration of Study: A field experiment was carried out during Rabi season 2023-24 at Instruction farm of Karunya Institute of Technology and Sciences, Coimbatore. Experimental field was silty clay loam in texture with available N (311.0 kg ha-1), P2O5 (15.7 kg ha-1), K2O (185 kg ha-1).

Statistical Design: Randomized Block Design (RBD).

Methodology: The study consist of 8 treatment and replicated three times T1- 100% RDF + FYM 12.5 t ha-1 + 2% DAP, T2- 100% RDF + FYM 12.5t ha-1 + 2% Urea, T3- 100% RDF + FYM 12.5 t ha-1 + 40 ppm NAA spray, T4- 100% RDF + FYM 12.5 t ha-1 + 10 ppm Salicylic, T5-100% RDF + FYM 12.5 t ha-1 + 75 ppm GA3, T6- 100% RDF + FYM 12.5 t ha-1 + 5 kg TNAU Pulse wonder T7- 100% RDF + FYM 12.5 t ha-1 T8- Control.

Results: Application of 100% RDF along with 12.5 t ha-1 FYM + 5 kg ha-1 TNAU pulse wonder resulted in Maximum nutrient NPK uptake, nutrient availability and agronomic efficiency was observed.

Conclusion: Application of full dose of RDF along with FYM and TNAU pulse wonder reacted better in terms of NPK uptake, nutrient availability and agronomic efficiency when compared to other foliar treatment in the evaluation of nutrient balance and nutrient use efficiency.
