Abstract: To explore optimum composition of high yielding cultivation for local sweet-waxy maize, the influence of fertilization and planting density on main agricultural characters and yield in‘Dinuo278’were researched. The results showed that: root weight and soil bulk density was highly significant negative correlation, and highly significant positive correlation with soil porosity. Differences in leaf area reached a significant level in respective fertilization and planting density treatments. Under certain conditions of the planting density, the affect of fertilization treatments on fresh ear weight were A1 > A2 > A3. Under certain conditions of the fertilization levels, the impact of planting density on fresh ear weight was B1 > B2 > B3. Single ear weight saw a significant positive correlation with plant height, leaf area, ear length and stem diameter. Total production was significantly positively correlated with plant height and single ear weight, highly significant positive correlation with leaf area, ear length, stem diameter and no significant level with ear height and ear diameter. For‘Dinuo278’, the highest yield was got when its planting density was 49500/hm2.
