Abstract:

A field experiment was conducted to study the effect of different sources and graded levels of sulphur on growth, yield attributes and yield of bellary onion at National Institute for Abiotic Stress Management, Malegaon Khurd, Baramati, Pune, Maharashtra. The treatments comprised of three sources of sulphur (Elemental sulphur- Bentonite clay, Potassium schoenite and ammonium sulphate) with graded levels of sulphur viz., 0, 30, 45 and 60 kg S ha-1. The experiment was laid out in randomized block design with four replications. The recommended doses of fertilizers were applied as per the crop production guide. Growth parameters viz., plant height, number of leaves and neck size were recorded at 30, 60, 90 and 120 DAT and yield attributing parameters viz., polar diameter, equatorial diameter and bulb yield were recorded at harvest. The results showed that growth attributes viz., plant height, number of leaves, neck size and yield parameters viz., polar diameter, equatorial diameter and average weight of bulb increased significantly up to 45 kg S ha-1 and thereafter, declined in all sources of sulphur. The maximum bulb yield was obtained with the application of 45 kg S ha-1 and it was significantly superior to 30 kg S ha-1 and at par with 60 kg S ha-1 in all sources of sulphur. Among the methods of application, 45 kg S ha-1 as superior over nutripellet pack as soil application shows superiority over all other treatments.
