Abstract
Onion is one of the commercial vegetable crops of India. Sulphur has been recognised as an important nutrient for higher yield and quality of onion bulbs. Keeping this in view, a field experiment was conducted at AINRP on Onion and Garlic, College of Horticulture, OUAT during rabi, 2010-11 to study the effect of sources and levels of sulphur on growth, yield and bulb quality in onion. The treatment consists of two sources of sulphur and four levels of sulphur by adopting Factorial RBD with three replications. The results on vegetative growth (plant height, number of leavesplant-1 and neck thickness), yield attributing parameters (bulb weight, equatorial and polar diameter), total bulb yield, Physiological Losses of Weight (PLW) and Total Soluble Solid (TSS) revealed significant variations among the levels of sulphur in onion. However, no significant variations were recorded between the sources of sulphur in onion, except bulb weight. Gypsum recorded higher plant height, neck thickness, average bulb weight, polar diameter, total bulb yield and TSS than elemental sulphur. Gypsum as a source of sulphur also reduces the production of doubles and bolter along with better shelf life of onion by reducing PLW, rotting and sprouting. Among the levels of sulphur, irrespective of sources, sulphur @ 30 kg ha-1 recorded significantly higher plant height (54.51 cm), number of leavesplant-1 (14.80), polar diameter (5.17 cm), equatorial diameter (5.17 cm), average bulb weight (60.83 g) , total bulb yield (211.23 q ha-1) and TSS (11.90%) than other levels. However, statistically parity was observed with application of sulphur @15 and 30 kg ha-1 for above mentioned parameters. Application of sulphur @ 30 kg ha-1 in form of gypsum may be recommended in onion crop for obtaining higher bulb yield having better keeping quality.
