| The objective of this experiment was to investigate the advantages of seed production of three legume crops, stalkless yard long bean, cowpea and soybean; as intercropping in new rubber plantation. Each legume crop was planted 2 rai. Soil analysis was conducted before and after planting the intercropping legumes. Growths of rubber plants with and without intercropping were monitored monthly until harvesting legume.
