Low yields are a result of poor soil health, poor agronomic practices, erratic weather and other factors. Applying lime can improve soil health. One can also apply manure to improve organic matter content.
Ground application of fertiliser, complemented with appropriate foliar fertiliser address plant nutritional requirements.
Poor quality beans can be a result of drought, low nutrition, attack by pests and diseases or poor processing. Foliar fertilisation is key during drought. It helps the plant cope with biotic and abiotic stress while giving the much-needed nutrients.
