| Abstract: | In order to improve the yield of millet and use efficiency of fertilizer in semi-arid area,the effect of N fertilizer applicated at late growth stage on yield of millet and soil fertility status were studied. The results showed that the yield increased by 4. 04% than conventional fertilization, fertilization amount decreased by 15. 78% ,fertilizer inputs decreased by 8.69%. N fertilizer applicated at late growth stage had significant effect on reducing fertilizer amount,fertilizer inputs,environmental pollution and increasing the yield. |
