Abstract

A field experiment on faba bean (Vicia Faba) was conducted at Abu-Rawash Experimental Station, Giza. Treatments were three irriga­tion intervals (4, 6 and 8 days) with sewage water and three concen­trations of zinc (0 , 0.4 and 0.8%) as zinc sulphate. Crop production showed a high response by using sewage wa­ter for irrigation. Both straw and seed of faba bean were significantly increased by decreasing the intervals between irrigations, i. e. the yield took the following order : 4 >6 > 8 day. In addition, irrigation on every 4 days and 0.04% Zn SO4 solution gave the best yield of faba bean (1.908 tons seed/feddan and 8.860 tons straw/feddan). This clarifies that the moisture content of sandy soils is the most impor­tant factor for their productivity.
