Abstract


Citrus is an important cash crop in the Sudan. In addition, it is one of the major sources of human diet due to its high nutritive value, especially vitamin C (Bedri, 1984). Its cultivation is native to tropical and subtropical regions. Total area of citrus in Sudan is estimated as 45654 ha (National Horticulture Administration, 2013). Irrigation is one of the most important factors in producing a good yield of quality citrus. Poor irrigation and water stress significantly depress root elongation and reduce fruit number, size and weight (Saeed et al., 1990). Bubbler irrigation is a combination of surface and drip irrigation that needs a small basin, because the discharge is too high, about 50 to 225 liters per hour to infiltrate. It is usually used for orchard and big trees (Ismail, 2002). Ibrahim et al. (2012) reported that bubbler irrigation gave the highest values of growth parameters, while the basin irrigation gave the lowest values of date palm. Research on proper water management on fruit trees is very little in the Sudan. Hence, studies on design, implementation and management of water application methods for citrus and other fruits are highly needed. The objective of this research work was to evaluate the water productivity, yield and quality of foster grapefruit irrigated by bubbler and surface irrigation under Khartoum State conditions.
