| Abstract: | The planting densities and nitrogen fertilization for maize(Zea mays L.) were studied in 1991. This experiment was engaged in three different ecological conditions, including soil, climate and so on. Regression equations were established by electronic computer according to the ex- perimental results. The analysis of economical benefit with these regres- sion equation showed that higher net income can be obtained when op- timum planting density and proper nitrogen quantity are applied. |
