Abstract

The present experiment was carried out on the planting dates and forms of sulphur on chemical characteristics of 'Pusa Red' cultivar of onion (Allium cepa L.) during Rabi season of 2013-14 at three different dates, viz., 15^th November 2013, 15^th December 2013 and 15^th January 2014 and three doses of elemental sulphur and gypsum each 20, 40 and 60 kg/ha at Horticultural Research Farm of the Department of Applied Plant Science, School for Bio science and Biotechnology, Babasaheb Bhimrao Ambedkar University, Lucknow (U.P.). The experiment was laid out in Factorial Randomized Block Design with three replications. The data clearly revealed that higher TSS, ascorbic acid content in bulb were recorded in early planting (15^th November with 60 kg/ha and 40 kg/ha), respectively and significantly higher reducing sugar, non-reducing sugar and total sugars were obtained with early planting i.e., 15^th November with 20 kg/ha of elemental sulphur, while higher content of pyruvic acid was found in late planting (15^th January with 60 kg/h of elemental sulphur) of the crop.
