| dc.description.abstract | A field experiment was conducted to study the response of transplanted onion to sulphur and zinc nutrition during summer season of 2015 at farmer’s field in Vijayapura district (Zone-3). The treatments comprised combinations of four sulphur levels and three zinc levels along with a RPP, RDF and farmer’s practice (control). Totally fourteen treatment combinations were tested using randomized complete block design with three replications. The results on growth parameters, yield attributing parameters (bulb weight, bulb diameter and bulb index), bulb yield, quality parameters (TSS, bulb grading and bulb dry matter), nutrient uptake and status of available nutrient content in soil revealed significant variations among sulphur and zinc levels in onion. Among the treatment combinations, the treatment which received, RPP + 40 kg sulphur ha-1 + 10 kg zinc ha-1 has recorded significantly higher plant height, leaf area plant-1, dry matter accumulation in leaf, bulb and total dry matter accumulation at different growth stages (at 30, 60, 90 DAT and at harvest), bulb weight plant-1 (110.07 g), bulb diameter (41.90 mm), bulb index (1.91) and bulb yield (406.23 q ha-1) when compared with control. The quality parameters viz., TSS (13.89 %), A, B, C grade bulbs and lowest unmarketable bulbs, higher bulb dry matter were superior over control treatment. The uptake of N, P2O5, K2O, S and Zn as well available nutrient content of S and lower availability of N and P (at harvest ) in soil were recorded significantly higher values over control. The significantly higher net returns (` 4,43,019 ha-1) and B:C (3.58) were noticed with the treatment which received RPP + 40 kg sulphur ha-1 + 10 kg zinc ha-1 as compared to control. | en_US |
