The embryo has onecotyledon or seed leaf in monocotyledons, two cotyledons in almost all dicotyledons and two or more in gymnosperms. Fertilisation Fertiliser application in cowpea production depends on anticipated yield and soil fertility. The inter-row and intra-row spacing depends on the type of variety of cowpea grown and the growing pattern, but generally for grain production, a plant population of 200,000 to 300,000/ha at 30 to 50cm inter-row spacing is preferred. A typical seed includes three basic parts: (1) an embryo, (2) a supply of nutrients for the embryo, and (3) a seed coat. Local prostrate varieties should be planted wider spacing of 80 cm × 40 cm.
