| Abstract | ||||
| This experiment was carried out during two successive crop cycles of 2009/2010 (first ratoon plant) and 2010/2011(second ratoon plant) on Williams Ziv banana (Giant Cavendish AAA subgroup) grown in sandy soil to determine the optimum water requirement under two irrigation systems (drip and minisprinkler systems). Four rates of water (7000, 8750, 10500 and 12250 m3/Fed./year) and the plants were fertilized with organic cattle at the rate of 150 m3/Fed.year. Results show that: Growth parameters of plant i.e. pseudostem height, circumference, in Dec. number of green leaves and assimilation area at bunch shooting stage significantly increased by increasing the amount of applied water. Drip irrigation gave the highest values for the two above characters compared with minisprinkler system. Time of flowering, harvesting and growth cycle of plants tended to decrease as irrigation water was increase. Drip system shortened the growth cycle duration of Williams Ziv binan. The highest yield per fed., average bunch and finger weight and fruit were achieved from Williams Ziv banana plants received of water 8750 m3/Fed./year under drip irrigation system. Water utilization efficiency (WUE) was affected with the amount of water and worked irrigation system. The better value of WUE (4.05 &3.47 Kg.fruit / one m3 water) was obtained from plants received 8750 m3/Fed./year water under drip irrigation system. Adding organic manure had a favorable results on growth might be related to the improvement on the physical, chemical and biological properties of the soil which increase the availability water and nutrients for plants. Under similar condition it is a recommend for Williams Ziv banana growers to apply of water 8750 m3/Fed./year under drip irrigation in sandy soil for the promising yield of good fruit quality, the following excretion water irrigation program could be suggested in Jan. 250 m3 water / Fed, Feb. 312.2 m3 water / Fed, Mar. 562.5 m3 water / Fed, April 750 m3 water / Fed, May 812.5 m3 water / Fed ,Jun. 937.5 m3 water / Fed , July 1125 m3 water / Fed, Aug. 1125 m3 water / Fed, Sep. 937.5 m3 water / Fed., Oct. 875 m3 water / Fed., Nov. 625 m3 water / Fed and Dec. 437.5 m3 water / Fed. | ||||
