Abstract

Afield experiment had been carried out in autumn -2006 to study the effect of irrigation depth and foliar nutrition application of Zinc on some growth for the spicies Zea mays L.var IPA 5012. A factorial experiment was applied according to Randomized Complete Block Design with three replicates .The experiment included two treatments namely; irrigation (I) with two levels (I1 and I2). The I1 treatment received enough irrigation in germination and maturing stags which equal (130 and 150) mm respectively, but received deficient irrigation in vegetation and flowering stags which equal (180 and 140) mm respectively. The I2 treatment received deficient irrigation in germination and maturing stags which equal (65 and 95) mm respectively, but received enough irrigation in vegetation and flowering stags which equal (225 and 215) mm rspectively. The second treatment namely Zinc spraying (Zn) which contents three levels (Zn0, Zn1 and Zn2). The Zn0 treatment, is the control (sprayed with water only). The Zn1 treatment in which the plant sprayed three times with 50 mg Zn/ L, and the Zn2 in which plant sprayed three times with 100 mg Zinc/ L.
The results showed: that I2 treatment gave the highest growth indicators particularly net weight seed/ ear, weight of one seed and wet weight of plant which shows (15.6, 4 and 12)% increament continuously comparing with I1 treatment. While The Zn1 treatment gave the highest level for net weight seed/ ear, wet weight of plant ,number of seeds in one line and leaf width. The increasing percent were (6.7, 2.3), (16.9, 10.8), (6.7, 1.5), (5.9, 5.0)% in comparesing with Zn0 and Zn2 treatments, continuously. Also Zn2 treatment showed a significant increament in ear length. The increasing percent was 6.8% in comparing with Zn0. I2Zn1 achieved a significant increament in the average of net weight seeds/ ear, and weight of one seed. Also interaction of Zn1 with I1 and I2 showed a significant increament in the average of seeds number in one line and leaf width.
