| Title : | OPTIMIZING WATER PRODUCTIVITY, YIELD AND QUALITY OF GRAPEFRUIT IRRIGATED BY BUBBLER AND SURFACE IRRIGATION UNDER KHARTOUM STATE SUDAN CONDITIONS |
| Abstract : | The experiment was carried out in the private orchards at Tayba Alhasnab area of south Khartoum State, in Sudan during 2012 and 2013 to evaluate the water productivity, yield and quality of foster grapefruit irrigated by bubbler and surface irrigation system. Irrigation interval was 5 days in bubbler irrigation system and every 7 to12 days in surface irrigation system depending on the prevailing weather conditions. The results revealed that higher yield and number of fruits was obtained on bubbler irrigation system compared to surface irrigation system. Moreover, bubbler irrigation system increased the total yield of foster grapefruit by 28% and 25%, respectively as compared to surface irrigation system. Applying irrigated water under bubbler irrigation system improved the quality parameters of foster grapefruit such as fruit diameter recorded significant differences on bubbler irrigation system compared with surface irrigation system in both years, fruit weight and peel thickness recorded significant differences (P≤0.001) between bubbler irrigation system and surface irrigation system on finger weight, but on differences in peel thickness in both years, total soluble solids of foster grapefruit irrigated by bubbler irrigation system were significantly higher (P≤ 0.001) compared with surface irrigation system in both years. However, bubbler irrigation system saved irrigation water by 68% and 71% and had highest water productivity (2.9 and 2.7 kg/m3) compared to surface irrigation system (0.67 and 0.68 kg/m3). Also highest marginal rate of return was obtained with bubbler irrigation system compared to surface irrigation. |
