Objectives Broad objective To increase maize yield by reducing striga parasitism on maize by intercropping with green grams Specific objectives To evaluate the effect of intercropping maize with green grams on Striga parasitism and yields. To evaluate the effect of plant arrangement in an intercrop of green grams with maize in reduction of Striga. To determine the cost-benefit analysis associated with intercropping maize and green grams as a technology for Striga control.

Methodology Experiment site; Alupe KARI station, Busia county. Experimental design; RCBD Treatments;  Green grams planted in same hill with the maize.  One row of green grams planted between two rows of maize at 37.5cm from each maize plant.  Two rows of green grams planted between two rows of maize.

Methodology cont’  Broadcasting of green grams will be done in the maize field and thinning to coincide with the recommended green gram pure stand population plants per/ha.  Maize and green grams planted in the same hill plus one line of green grams between the maize rows  Maize alone with striga incorporated  Maize without striga.  Green grams sole crop.

Experiments in season one Determination of the effect of intercropping maize with green grams on Striga parasitism and yields. Determination of the effect of plant arrangement in an intercrop of green grams with maize in reduction of Striga. Determination of the cost-benefit analysis associated with intercropping maize and green grams as a technology for Striga control.
