The effect of nitrogen (urea) and zinc applied in different doses from the soil and leaves on the development, dry matter amount and mineral content of wheat and corn plants

This study was carried out to determine the effects of nitrogen and zinc applied in different doses (0.0, 5.0, 10.0 15.0 kg N/da 0.0 2.5 ppm Zn) soil sample taken from Erzurum Atatürk University Faculty Agriculture Farm land on dry matter content mineral wheat maize. It under greenhouse conditions 96 pots (2 plants, 2 application methods, 4 doses, 3 replications). As a base fertilizer, it all before planting at P2O5/da (TSP: 44.0% P2O5) K2O/da (K2SO4: 50.0% K2O). Considering applications, Urea Zinc fertilizers were application, foliar 5 times every weeks, starting one week after germination application. 90 days sowing, plants harvested, dried, their weights determined, necessary analyzes made plant determined.
 According results obtained, more effective, highest amount height both obtained kgN/da urea Zn. Depending increase is 77.5% 80.4% corn soil. In 11.4% 30.6% corn. A similar change has also emerged height, fertilizer are taller, with an average 62.5 cm 75.5 These values 55.0 64.0 fertilizer. The higher.
