Economic analysis of combining inorganic fertilizer and improved seed with other complementary interventions has proved to be profitable. For instance, Lunduka and Kelly (2012) found that addition of the organic and inorganic fertilizer and intercropping with legumes increases net profit per hectare. Intercropping maize with pigeon peas also provides high net returns when combined with inorganic fertilizers. For example, fertilizing maize under a pigeon peas intercrop had the highest profit of US$ 305/ha which was about US$ 100 more than sole maize crop in in Tanzania, and intercropping maize with half the recommended fertilizer rate gave almost similar profit margins to sole maize with full fertilization (US$ 232/ha and US$ 231/ha respectively). In Kenya, trials indicated combining manure with inorganic fertilizer on maize gave an additional profit of US$ 180/hectare relative to applying sole fertilizer.
