Abstract: A field trial on influence of sulphur and zinc combination on growth, yield and quality of onion var. Arka Kalyan was carried out during Kharif 2015 and Kharif 2016 at Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka. The experiment was laid out as two factorial RBD involving four levels of sulphur (0, 20, 30 and 40 kg sulphur/ha) and zinc (0, 5, 10 and 10 kg zinc/ha) comprising 16 treatment combinations of sulphur and zinc including control (S0Z0). Sulphur and Zinc fertilizers were applied one month after the transplanting as per the treatment combinations. The maximum plant height (52.03, 52.59 and 52.31 cm), number of leaves (9.37, 10.72 and 10.04), leaf area (68.72, 66.69 and 67.71 cm2), leaf area index (0.46, 0.44 and 0.45), neck thickness (9.54, 10.59 and 10.06 mm) at 90 days after transplanting (DAT) and also higher bulb yield (21.70, 21.90 and 21.80 t ha-1) was recorded by S3 (RDF+40 kg S/ha). Among the zinc levels, Z3 (RDF+15 kg Zn/ha) recorded maximum plant height (48.66, 50.10 and 49.38 cm), number of leaves (7.83, 9.57 and 8.70), leaf area (56.81, 57.29 and 57.05 cm2), leaf area index (0.38, 0.38 and 0.38) and higher bulb yield (21.03, 21.30 and 21.17 t ha-1). Among the interaction effect S3Z3 (RDF + 40 kg S/ha + 15 kg Zn/ha) recorded significantly maximum leaf area (75.41, 73.77 and 74.59 cm2) and leaf area index (0.50, 0.49 and 0.50) and also registered significantly maximum bulb yield (23.22, 24.51 and 23.87 t ha-1) in 2015, 2016 and pooled data respectively.
