Abstract
Information on phosphorus sulphur fertilizer requirements of some new sesame varieties in Semi-Arid ecological regions is deficient therefore the need to evaluate the effects of P and S has become necessary.Two sets of experiments were carried out to evaluate the effect of phosphorus and sulphur on the oil content of sesame (Sesame indicum L.). The experiment was conducted during 2009 raining season at Teaching and Research Farm, Faculty of Agriculture Bayero University Kano (110 58 and 80 25 1 E) and Jahun, Jahun Local Government of Jigawa State (120 31 N and 90 351 E). The soils of two locations were sandy loam, with 800 mm and 400 mm of rainfall at Kano and Jahun site respectively. The treatment included three sesame varieties (E8, Sudan and Yandev 55), four levels of P2 05 (0,20, 40 and 60 kg ha-1)and four levels of sulphur (0, 15, 30, and 45 kg s ha-1 ). A Randomized Complete Block Design was used and replicated three times. Result revealed that sesame variety and phosphorus fertilizer had significant effect on oil content (48.8 %) at Kano. Sulphur had significant effect on oil content at Jahun where 30 kg S ha-1 produced 49.66 % oil. Sudan variety had the highest oil content and E8 had the lowest oil content. There was interaction effect between variety, phosphorus and sulphur on oil content at Jahun. Therefore, sesame need fertilizer for good production of oil and more investigation should be carried out for confirmation.
