Abstract:

Two field experiments were conducted with taro (C. esculenta) in Egypt during the two successive summer seasons of 1997 and 1998 to study the effect of irrigation intervals, NPK fertilizer levels and their interactions on yield and its components. The irrigation intervals were 1/2, 1, 1 1/2 and 2 weeks and the NPK fertilizer levels were 0:0:0, 30:16:48, 60:32:72, 90:48:96 and 120:64:120 kg/feddan. Irrigation every half week intervals and/or application of 120 N+64 P2O5+120 K2O kg/feddan each alone or their combination significantly affected yield and its components, expressed as number and fresh weight of cormels, fresh weight of main corm, height and diameter of main corm, total yield per plant as well as total yield per feddan. Water use efficiency was improved by applying the highest quantity of water and the highest level of NPK.
