| Abstract: |
| To study the effects of different nitrogenous fertilizers on the yield and quality of broomcorn millet, Jinshu 9 was used as the material in this study. The results showed that protein content was significantly greater than CK, and starch content was significantly less than CK. The highest yield was by the treatment of PN2, with an increasing rate at 28.48%. Yield displayed a significant positive correlation with panicles and grain weight per plant, and the correlation coefficients were 0.81 and 0.62, respectively. Millet yield was significantly positive correlation with grain protein content with a correlation coefficient at 0.83, and was negatively correlated with the grain starch content with a correlation coefficient at -0.44. Under the experimental conditions, increasing the yield of broomcorn millet mainly through the increase of panicles and grain weight per plant. The level of nitrogen application at 150 kg·hm-2 was found to be optimal in this region. We can see are not all soil types are suitable for the slow-release urea. The types of sandy soil retention of fat and water ability is poor, air permeability is good, so more suitable for the ordinary urea. |
