| Abstract: | Based on literature and investigative trial results, major factors influencing alfalfa seed yield include ecological environment, population density, phosphate fertilizer, trace element fertilizer, soil moisture, pollination, growth regulators, insect pests, weeds, and time of harvest. During the growing course, factors including density, soil moisture, and pollination are particularly important. |
