Treatments included planting patterns with 5 levels (sole roselle, 75% roselle+ 25% cowpea, 50% roselle+ 50% cowpea, 25% roselle+ 75% cowpea and sole cowpea). Results showed that planting ratios with cowpea had significant effects on plant height, stem diameter, lateral branch and number of bolls per plant of roselle. The effect of planting ratio with roselle was significant on number of pods per plant, number of seeds per pod and 1000-seed weight of cowpea. The maximum of plant height (182.75 cm) and lateral branches (84.3) of roselle were achieved in planting ratio of 75% roselle+ 25% cowpea respectively. Also, the highest 1000-seed weight and number of pods per plant were obtained in sole cropping. The maximum LER (1.65) was computed in planting ratio of 75% cowpea+ 25% roselle. This means that seed yield in intercropping improved up to 65% as compared with sole cropping. According to LER obtained, it can be stated that planting ratio of 75% cowpea+ 25% roselle can be significantly increase economic income and agricultural land productivity.
