Sunflower is important oil seed crop for human being diet and sulphur plays major role in increasing the achen yield and oil content. A field study was conducted to observe the effects of sulphur on sunflower growth, oil content and yield. The sulphur rates were 0, 5, 10, 15, and 20 kg ha-1. The recomended rates of nitrogen, phosphorus and potasium were given to all plots of different treatments. The economical important plant growth parameters ; height of plant (cm), stem girth, diameter of flower disk (cm), quantity of achenes (head-1), weight of 1000 achenes, oil (%) in achene, yield (ha-1), and sulphur content (%) in plant straw were evaluated. The values among the treatments for higher plant height (161.80 cm), wide stem girth (4.80 cm), flower head diameter (15.40 cm), maximum number of achene head-1 (787), weight of 1000 achenes (50.29 g), higher grain yield ha-1 (650.33 kg), oil content % (42.20), achene yield plant-1 (39.57 g) and sulphur content % of plant straw (0.225) were recorded when sulpher rate at 20 kg ha-1 were applied to crop. These values were significantly higher compared to other S levels of 5,10 and 15 kg ha-1. The outcome of experiment had revealed that with the increasing level of S, the sunflower plant growth and yield attributes were significantly improved. The application of sulphur at 20 kg ha-1 was superior in enhancing overall growth, achene yield and oil content % of sunflower. [ABSTRACT FROM AUTHOR] |
