Intercropping Napier Grass with Maize Controls Destructive Stem Borer

by Kenya Farmers

Growing using crops with push and pull method is a costless practice that can save farmers from cereals loses to pests yearly.

Napier grass for instance, can protect maize crop against this pest. Napier grass is a repellent crop.

Stem-borers would lay eggs on Napier grass, but they will not develop to larvae. Planting one line of Napier grass also repels moths, a development stage of stem-borer, from the field.

Napier and other desmodium plants also inhibit growth of striga weed, which attacks maize and other crops like rice. A farmer should clear and harrow land to a fine tilt before the onset of rains.

Demarcate the land into plots and plant three rows of Napier grass along the border at a spacing of about 75cm by 75cm.

Desmodium should be alternated with maize in rows. At a spacing of 75cm by 30cm, maize should have a one meter margin away from the inner row of the Napier grass.

Early weeding enables push-pull plot protection-probably when maize is three and five weeks old.

Maize being a heavy nitrogen feeder, the leguminous desmodium would fix the element into the soil. The highly nutritious crop will also be utilized as fodder for animals just like Napier grass
