Abstract:
A field experiment was conducted out at Shabaa Research station, General Agricultural research community, Damascus to study fertilizer application methods and doses of Zn (soil application: 4 & 8 kg Zn/ha, and foliar application: 2 & 4 mg Zn/l) on some properties of the physical, chemical and fertility soil, as well as the cropping characteristics of the yellow corn variety Ghouta 82, such as the length of the ear, the number of rows in the ear, the number of grains in the row, the number of grains in the corn, the weight of a hundred grains and the grain yield. The results showed no significant differences in most soil characteristics at flowering stage, but significant differences were found at maturity stage. Zn concentration in plant tissue significantly increased when added Zn by all types and doses comparing with control. High doses of fertilizer treatments had superiority over control and had highest values for crop traits, yield components and grain yield. The foliar application was better than soil application in production traits, and the foliar application treatment by (4 mg Zn/l) had highest Zn concentration in plant tissue (59.76 ppm, plant high (177.0 cm), weight of 100 kernel (25.9 gr) and grain yield (556.3 kg/ha).
