Role of watersupply in monoculture maize (Zea mays L.) production

The effects of agricultural management factors and the various yield component on the yield results of maize were studied in a 24 year old monoculture maize long-term experiment. We concluded that the application of greater fertilizer doses leaded to yield surplus. Irrigation had an extremely moderate yield increasing effect at every irrigation treatment due to very favourable water supply. Our scientific results showed that if we applied higher doses of fertilizers than the nutrient- and water supply of maize increased. Among the yield components the corn cob lenght, the corn cob weight and the thousand grain weight influenced the yields.
