Abstract

Aim: To evaluate the nutrient use efficiency of short duration red gram varieties under site-specific nutrient management. Place and Duration of Study: The experiment was carried out in the rabi season of 2023 at an experimental farm in Karunya Institute of Technology and Sciences, Coimbatore. Experimental field was silty clay loam in texture with medium in available N (295 kg/ha), high in available P2O5 (kg /ha) and high in available K2O (285 kg/ha). Study Design: Split plot design. Methodology: The treatments consisted of three varieties in main plot namely V1- APK 1, V2- VBN 3, V3- VBN 1 and eight treatment in sub plots T1- (+NPK), T2 - N (-PK), T3 - P (-NK), T4 - K (-NP), T5 - PK (-N), T6 - NK (-P), T7 - NP (-K), and T8 - Control (-NPK). Result: Applying fertilizer as per recommended dose of nutrients without nutrient omission, resulted in increased nutrient use efficiency, agronomic efficiency, partial factor productivity and partial nutrient budget.
