Abstract

Maize (Zea Mays L.) is the most represented agricultural crop in the territory of the Republic of Croatia. Achieving high yields and good grain quality is possible if agricultural production is adapted to climatic conditions and the needs of the cultivated crop. The aim of the work was to determine the elements of maize irrigation in the area of Orahovica ( Croatia), depending on climatic factors such as: precipitation, air temperature, wind, relative humidity and insolation, and the sowing dates. By analyzing data of the 2011-2021 year period, the need for maize irrigation was determined. In average years in terms of maize production, the irrigation norm is 132 mm, and in dry years 268 mm. The irrigation norm of post corn is 98,9 mm in dry years. The available water and maize yield are proportionally changing values, which means that the lack of precipitation negatively affects the yield and vice versa. In order to avoid a reduced yield due to abiotic stress caused by drought, it is necessary to implement the agrotechnical measure of irrigation. In addition to ensuring a sufficient amount of water for the development of maize, irrigation can also extend the sowing dates
