Résumé partiel
The experiment was established in the Horticultural Research Centre Farm, Agricultural Research Corporation, Wad Medani, Sudan during16th November 2009 and 16th October 2011. The soil used on the experimental site is silty clay loam soils with high silt content (68%). A drip irrigation system was designed and installed on an area of 2145 m2. The system was evaluated for its performance relative to the conventional surface irrigation method. Three months old planting material propagated by tissue culture was transplanted in the field on 16th of November, 2009 at spacing of 3×3 meter (1111 mother plants/ha). Three months after planting two sucker were left (2222 plants/ha) and population was maintained thereafter. Five irrigation treatments were applied under drip irrigation system. These were 40%, 60%, 80%, 100% and 120% of crop evapotranspiration (ETc). The traditional surface irrigation was used as a control. Irrigation interval in drip irrigation system was applied every other day. In surface irrigation method, irrigation scheduling was every 3 days at the beginning, then the interval was increased gradually to every 5-10 days depending on the prevailing weather conditions. The treatments were replicated four times in a randomized complete block design (RCBD) and four plants represented experimental plot. The parameters measured included plant height, plant girth, number of green leaves, leaf area, number of days from planting to shooting and harvesting, yield and yield components and total water applied. Irrigation water productivity, nutrients use efficiency and economic analyses were determined
