Title: Determining elements of variety-specific maize production technology
Abstract: In order to enchance the adaptability and yield stability of maize, the effect of nutrient supply and plant density on yield was studied on a calcareous meadow soil in Hajduboszormeny. The effect of these crop rotation and planting time and grain moisture at harvesting time is also influenced by the close correlation between ecological and biological factors.The yield of maize in monoculture crop rotation decreased by 1-3 t ha -1 in each dry year during our experiment. The fore crop determined the doses of fertilizers mainly influenced the doses of nitrogen. In triculture (peas – wheat – maize) crop rotation (after wheat fore crop) The optimum N-dose was 50-60 kg ha -1 , and in monoculture the optimum N-doses increased to 100-120 kg ha -1 . In monoculture crop rotation the soil fertility and the microbiological activity of soil is decreased. At early planting time the grain moistures wereless by 5-12 % lower compared to the late planting time. A 10 thousand plants ha -1 change in stock density can increase yield by 1.5-2.0 t ha -1 .
