Modern water management can influence the plant product in a very complex manner. Maize typically utilizes the water resources of the soil, which is also due to its extensive root stock. The optimal water requirement under the breeding time is 400-450 mm. From the point of view of maize water demand, however, the summer months are the most critical and during this period the daily water consumption varies between 4 and 6 mm. In the absence of precipitation, this amount of water should be replaced by irrigation to achieve the right quality and amount of crops. 15-20% of irrigated areas are covered by maize, which is about 20 to 25 thousand hectares. During our research, we studied the yields of maize at four nutrients level, in irrigated and not irrigated conditions. Experimental parcels size 10m x 5m. The 5 m parcel width allows you to get 6 lines with a 76 cm row spacing in each one, so this was a small parcel experiment The results clearly demonstrated that irrigation is an inevitable factor in the economical cultivation of maize, even at a vintage when it is in the most important period of maize, that is, there is an adequate amount of water in the natural precipitation at the time of flowering, but at the time of true crop training should be counted The research was carried in Szarvas, at the school experimental field of the Hungarian University of Agriculture and Life Sciences, Department of Irrigation and Melioration, in 2021.
