Title: Effect of Water Quantities and Weeding on The Vegetative Growth and Yield of Sunflower (Helianthus annuus L)
Author: Betek, Samia Gaffar Mohamed
Abstract: The effect of three water quantities (400 mm, 500mm, 600mm) and three hand weedings on vegetative growth and yield of sunflower (hybrid Hysun 33), was investigated in season 2000/2001, in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat. The results showed that water quantity has no significant effect on plant height, number of leaves per plant, shoot dry weight, relative turgidity, number and weight of seeds per plant, 1000 seed weight, harvest index, percentage of empty seeds , nor on the final yield. However, increased water quantity significantly increased stem and disc diameter, leaf area index and oil percentage. Weeding did not affect plant height, number of leaves per plant, number of seeds per plant, 1000seed weight, harvest index, percentage of empty seeds, oil percentage, nor the final yield. However, weeding significantly affected stem diameter, shoot dry weight, relative turgidity, leaf area index and weight of seeds per plant
