Companion Planting with Onions

Onions repel or distract pests like aphids and carrot flies and should be planted with crops except beans, lentils, peas, and parsley. Companion planting onions with other crops can benefit both plants by keeping pests away. Intercropping legumes with grains like sorghum in zai pits increases food production by 250% and improves soil nitrogen. Farmers in Africa are using companion planting with weeds like napier grass and desmodium to trap pests and increase maize yields by 60-70%.
