Title: Effect of Water Quantities and Spacing on Growth and Yield of Groundnut (Arachis hypogaea L.)
Author: Elsadig Ali Mohammed Hamouda
Abstract: A study was carried out for one year in the field to investigate the effects of four water quantities, applied at a fixed interval (7 days) and two levels of spacing, on the growth and yield of groundnut cultivar Wad Medani. A second objective was to determine the efficiency of water use (amount of water use produced one unite of dry matter ). Increased water quantities increased the attributes of vegetative and reproductive growth such as plant height, shoot dry weight, leaf area index, relative turgidity, number of pods per plant, 100-seed weight, final yield and water use efficiency. Number of leaves per plant, number of primary branches per plant, number of seeds/ pod and shelling percentage were not affected by water quantities. Reduced spacing increased both vegetative and reproductive growth such as plant height, shoot dry weight, leaf area index, relative turgidity of leaves, number of pods / plant, 100- seed weight and final yield. Both shoot dry weight, number of seeds/ pod and shelling percentage were not affected by spacing. The yield components(particularly number of pods/ plant, and 100-seed weight) and final yield were mostly affected by both water quantities and spacing.
