Abstract: In order to respond to the national control of agricultural pollution,popularize the millet cultivation techniques of spring cultivation and early maturing areas,Datong 29 as the test material was planted and the different planting densities and nitrogen fertilizers were set up to study the suitable planting density and nitrogen fertilizer in order to grasp the dynamic changes of the population structure and the efficient use of nitrogen fertilizer.The results showed that it should apply nitrogen fertilizer during the jointing period and the suitable nitrogen fertilizer was 120-135 kg/ha.The suitable planting density was 330 000-360 000 plants/ha.The yield,stem diameter,spike length,biomass,spike weight and spike grain weight showed an increase trend and then decreased with the increased of nitrogen fertilizer.The yield showed an increase trend and the stem diameter,spike length,biomass,spike weight and spike grain weight showed a decrease trend as the increased of planting density,while the plant height showed an irregular trend.The interaction effect of nitrogen fertilizer and planting density was not obvious.SPAD value showed a significant correlation with yield and nitrogen fertilizer level,while not related to the planting density.Reasonable population structure and suitable nitrogen fertilizer are the important factors in millet cultivation of early maturing area.

Key words: With nitrogen levels, Planting density, Millet, Production, Agronomic traits
