An experiment was conducted at Horticultural Research Farm, COH, AAU, Anand during the three consecutive years 2021-22, 2022-23 and 2023-24 on Onion cv. Gujarat Junagadh Red Onion 11. The experiment was laid out in RBD with three replications and twelve treatments viz., T₁: 100% RDF (75:60:50 NPK kg/ha), T₂: 10 t FYM + 100% RDF (75:60:50 NPK kg/ha), T₃: 100% RDF (75:60:50 NPK kg/ha) + 20 kg S, T₄: 100% RDF (75:60:50 kg/ha) + 40 kg S, T₅: 25% RDN through FYM + 75% RDF + 20 kg S, T₆: 25% RDN through FYM + 75% RDF + 40 kg S, T₇: 25% RDN through VC + 75% RDF + 20 kg S, T₈: 25% RDN through VC + 75% RDF + 40 kg S, T₉: 50% RDN through FYM + 50% RDF + 20 kg S, T₁₀: 50% RDN through FYM + 50% RDF + 40 kg S, T₁₁: 50% RDN through VC + 50% RDF + 20 kg S and T₁₂: 50% RDN through VC + 50% RDF + 40 kg S. The observations were recorded on different growth, yield and economics. The treatment T₁₂ (50% RDN through VC + 50% RDF + 40 kg S) recorded significantly, maximum bulb weight (65.54 g), bulb equatorial diameters (6.13 cm) and bulb yield (42.83 t/ha) and net return (3, 27,825 ₹/ha) on pooled basis. Whereas, No. of leaves at 45 and 60 DAP and plant height at 45 and 90 DAP were found non-significant.
