摘　　要：This study evaluates the effects of green manure, inorganic fertilizers and their combinations on the growth and yield of soybeans in the Mount Cameroon Region. The experiment involved 10 treatments which include, 5 Mg/ha green manure, 180 Kg P/ha triple superphosphate fertilizer (P), 180 Kg/ha NPK (20:10:10), 2 Mg/ha green manure + 90 kg P/ha, 3 Mg/ha green manure + 90 kg P/ha, 5 Mg/ha green manure + 90 Kg P, 2 Mg/ha green manure + 90 kg NPK/ha, 3 Mg/ha green manure + 90 kg NPK/ha, 5 Mg/ha green manure + 90 kg NPK and a control. Plant growth characters were assessed every 14 days for a period of 70 days for the late (August) and early (March) planting seasons. The results indicated that plants supplied with 5 Mg/ha green manure had the highest plant heights of 60.7 cm, and this was significantly different from the control which had the least height (52.76 cm). Stem collar diameter was significantly (p 0.001) increased with treatments in both seasons. Plants supplied with 5 Mg/ha green manure recorded the highest stover yield (10.59 Mg/ha), and this was significantly different from the control which had the least (6.64 Mg/ha). Plants supplied with 5 Mg/ha green manure had the highest days to flowering (38 days), while plants supplied with 5 Mg/ha green manure + 90 Kg NPK had the least (33 days) which was significantly different (p 0.01). The highest number of pods per plant was observed in plants supplied with 5 Mg/ha green manure (57 pods per plants), which was significantly different from the control (39 pods per plant). Plants supplied with 5 Mg/ha green manure + 90 Kg NPK recorded the highest grain yield (4.97 Mg ha^-1), while the lowest grain yield was observed in the control (2.22 Mg ha^-1). Results from this study can be used by soybeans farmers in the Mount Cameroon region to enhance productivity of this crop and thereby improving their living standards and food security in Cameroon.This study evaluates the effects of green manure, inorganic fertilizers and their combinations on the growth and yield of soybeans in the Mount Cameroon Region.
