The seed rate for the African nightshade (Managu) is 50g per acre. ensure you purchase only certified seeds planting can be done by preparing a nursery bed first or simply planting directly on a well prepared field. Nursery preparation: Loosen the nursery soil and apply well-decomposed manure or DAP, making sure that the manure is well incorporated into the soil. Make drills that are 10 to 20 centimeters apart, where you will then sow the seeds and cover them lightly with soil. You may also choose to raise the nursery bed to aid in loosening the soil. The size of the nursery bed will depend on the amount of African nightshade you want to plant.

Regulars farm practices of the nursery bed which include watering once daily especially at the evenings, weeding and thinning continues. The African Nightshade seedlings will be ready for transplanting 30 days after seeding or when they have 5 to 6 true leaves and a height of between 10 to 15 centimeters.

The land where the vegetable is to be transplanted should be ready , fertile and free from weeds if the area is not that fertile, Phosphorus fertilizer should be applied in the form of DSP at the rate of 75 kgs per acre.

Irrigation: this is done by application of water to the plants mainly in the evening to ensure frequent and adequate moisture supply to the managu vegetable although this vegetable is drought resistant its important to grow with enough moisture to increase productivity

Weeding: this is done by uprooting unwanted plants that grows with the African nightshade to ensure that pest and diseases are prevented and also competition for nutrients with plants are reduced and discouraged.

collards, cabbages, broccoli are the best intercropping partners for African Nightshade. Research in Egerton University, Kenya has shown that intercropping crops from the nightshade family increase the leaf yield of kales (Sukuma Wiki). 



Aphids are a major pest, causing leaves to curl and become unattractive to customers. Aphids feed by sucking plant sap. Small aphid populations may be relatively harmless, but heavily infested plants usually have wrinkled leaves, stunted growth and deformed pods. Plants, in particular young plants, may dry out and die under heavy aphid attack. Heavy attack on older plants may cause crop loss by decreasing flower and seed production. Damage may also reduce seed viability.


The plant’s leaves and growth tips are susceptible to mites (very small, sucking arthropods) that result in twisted growth and low productivity. Generally, spider mites feeding may cause reduction in plant growth, flowering, number and length of berries, and number of seeds per berry. Damage is most severe when mites attack young plants. Mite damage may be particularly severe during the dry season.


Leaf spots of early blight are circular, up to 1 cm in brown, and often show a circular pattern which distinguishes this disease from other leaf spots. Early blight thrives best under warm wet conditions. Leaf spots first appear on the oldest leaves and progress upward on the plant. Entire plant could be defoliated and killed.

Alternatively, the managu crop can be harvested late in the afternoon and placed on banana leaves. These should be tied in small bundles. The flowers should be removed before the crop is taken to market. Water these bundles sparingly to retain freshness of the crop. This method of harvesting is the most preferred as it gives the farmer continual produce for 3 to 4 months. Remove the flowers regularly to ensure the managu plant continues to produce more leaves, instead of focusing its resources on developing the fruits.
