Effect of sources and doses of Sulphur on yield attributes, yield and quality of Linseed (Linum usitatissimum L.)

Abstract

A field experiment was conducted during rabi season of 2016-17 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (U.P.) to study the effect of different sources and doses of sulphur on yield, yield attributes and quality of Linseed ( Linum usitatissimum L.). The experiment consisted of ten treatment combinations comprising of three sources of sulphur (gypsum, Single Super phosphate and Ammonium sulphate) and four doses of sulphur (0, 20, 40 and 60 kg S ha-1). The experiment was laid out in Randomized Block Design each replicated thrice. The result showed that ammonium sulphate @ 40 kg ha-1 recorded maximum number of capsule plant-1 (124.73), seed capsule-1 (8.93) seed yield (1262.33 kg ha-1), stover yield (2830.40 kg ha-1), harvest index (30.81 %), test weight (5.94 g) and oil content (39.46 %), Each successive increase in the level of sulphur up to 40 kg ha-1 significantly increased the number of capsule plant-1, seeds capsules-1, seed yield, stover yield, harvest index, test weight and oil content. Among the sources of sulphur, ammonium sulphate, being at par with gypsum, proved significantly superior to other sources for number of capsule plant-1, seed capsules-1, seed yield, stover yield, harvest index, test weight and oil content.
