Abstract
Sulphur has become one of the major limiting nutrients in increasing the production of oilseed crops including safflower. To study the response of safflower to levels and sources of sulphur, an experiment was carried out from 1995-96 to 2006-07 at eight locations representing different agro-ecological regions of India. The soils were clay Chromusterts at Tandur, Phaltan, Parbhani and Indore, Typic Chromusterts at Annigeri, Vertic Ustochrepts at Solapur and Arnej and Typic Haplusterts at Akola. The treatments comprised of combinations of three levels of sulphur (15, 30 and 45 kg/ha) and four sources of sulphur [ammonium sulphate (AS), single super phosphate (SSP), elemental sulphur and gypsum] along with a control (no sulphur) replicated 3 times in randomized block design. The pooled analysis of seed yield data indicated that, at Akola, there was significant response upto 45 kg S/ha and SSP was the best source. At Annigeri, the crop responded significantly up to 30 kg S/ha and SSP was the best source. However, at Solapur, safflower responded upto 45 kg S/ha with SSP as the ideal source. At Indore, the response was significant upto 30 kg S/ha and SSP and elemental sulphur were equally effective. At Parbhani, safflower responded upto 30 kg S/ha and elemental sulphur was the best. At Arnej, safflower responded significantly upto 45 kg S/ha and AS was the best source. The response up to 45 kg S/ha was noticed at Tandur while at Phaltan, it was limited upto 15 kg/ha and SSP was the best source at both locations. The study clearly showed significant response of safflower to sulphur application and the magnitude of response and source of sulphur depended on the available soil sulphur status and soil type respectively.
