“The result indicated that application of 100% RDF+Zn+Fe (N: P: K-20: 30: 15 kg ha−1 + ZnSO4 5 kg ha−1 + FeSO4 5 kg ha−1) recorded significantly highest plant height (34.18 cm), dry matter (10.31 g plant−1), leaf area index (2.216), number of pods (32.38 plant-1), number of seeds (6.88 pod−1), seed yield (870 kg ha−1), straw yield (1843 kg ha−1), biological yield (2713 kg ha−1), harvest index (32.10%), gross return ( 50975), net return (34930 ha−1) and B-C ratio (3.18), respectively over rest of the treatments but it was at par with 100% RDF, 50% RDF+50% RDN through FYM and FYM 4t ha−1.”
