Weed control of maize (Zea mays L.) in university farming

Abstract

Purpose. Regarding the area of maize in Hungary, we can state that it is one of the largest crops grown in the area. Maize was grown on 1,048,070 hectares in Hungary in 2019. The purchase price depends, among other things, on the size of the sown area and the yields, but many other things can also have an impact in either a positive or negative direction. In recent years, the purchase price of maize has been around HUF 50,000/tonne. Maize is one of the heat-demanding plants that needs 500 mm of rainfall during its growing season to develop smoothly. The expected yield is significantly influenced by the type of soil grown. Meadow chernozem and brown forest soil are the most favorable for maize.
 Methods. The maize was sown on April 17, 2020. In the experimental area were selected 5 squares. A square has a floor area of 4 m2. In the research area were conducted three weed surveys. The dates were: May 18, June 22, and July 29, 2020. The following herbicides were released on 15th May: Sulcotrek (sulcotrione and terbuthylazine); Tegoplant (trisiloxane); Trend (adjuvant).
 Results. The area was harvested on 21 September by a combine harvester equipped with a corn tube breaker adapter. From an area of one hectare, 9.4 tons of crops were harvested with a moisture content of 14%.
 Conclusions. In the case of chemical weed control, it is recommended to use an agent or combination which is specifically aimed at reducing unwanted, in this case pine sorghum.
