Effect of Sulfur Levels on Two Sesame (Sesamum indicum L.) Varieties under Climatic Conditions of Pakistan

Abstract

Present study was carried out at Agronomic Research Area, University of Agriculture Faisalabad during summer season, 2011 to determine the best variety and optimum sulfur level to get higher yield of sesame crop. The experiment was laid out in randomized complete block design (RCBD) with factorial arrangement. The experiment comprised of; two varieties, (TH-6, T-89) and six sulfur levels (0, 10, 20, 30, 40 and 50 kg ha-1). It has been observed that the variety TH-6 was more responsive to the sulfur application than the variety T-89. The collected data showed that variety V1 (TH-6) gave significantly maximum number of seeds plant-1, number of capsules plant-1, 1000-seed weight, seed yield, oil content and protein content. Similarly, the sulfur level S6 (when 50 kg sulfur was applied) gave significantly maximum plant height, number of capsules per plant, number of seeds per capsules, 1000-seed weight, seed yield, and oil content of sesame. For obtaining higher yield and good nutritional value, sulfur fertilizer should apply at the rate of 50 kg ha-1 and the variety TH-6 should grow under the irrigated condition of Faisalabad.
