The influence of NPK fertilizer on yield of alfalfa seed was observed in the mountainous area of southern Ningxia. The results showed that the seed yield was highest in processing of nitrogen 24 kg/hm2,phosphorus 90 kg/hm2,no potassium fertilizer and fertilizer in branch period seed . The average seed yield was 483.58 kg/hm2 and 3.57% ~ 20.8% higher than of the check. The results also indicated that the processing combination was optimal combination of NPK fertilizer under the conditions of alfalfa test.
