Abstract


Drip irrigation is one of the most efficient methods of water use for crop production. Family drip systems are suitable for small land areas ranging from 10-2000 m2 to irrigate horticultural crops. The system is a complete drip irrigation unit. It operates by gravity from a tank placed one meter high. It is a closed pipe-gravity system, and solid seasonal installation, for growing vegetables, flowers and other horticultural crops on flat or minor slope land. This experiment was established to evaluate a family drip system in comparison with surface irrigation for onion production under north Kassala conditions (Talkouk Locality). The results indicated that family drip system saved irrigation water by 67% and 59%, and increased the total yield of onion by 43% and 34% in sites one and two, respectively, as compared to local surface irrigation. The highest irrigation water productivity (2.98 and 2.73 kg/m3) was obtained under family drip system and the lowest values were 1.25 and 1.28 kg/m3 under surface irrigation in sites one and two, respectively. Moreover, the family drip system scored higher net return and benefit cost ratio compared to the surface irrigation system.
