Results showed that farmers were adopting technological components in a step-wise fashion. All sampled farmers adopted row planting and 83% and 58% in intermediate and highland zones, respectively, grew maize in pure stands. Sixty-five percent and 79% of the farmers in intermediate and highland zones, respectively, used inorganic fertilizers. About 36% and 51% of the sample farmers in intermediate and highland zones, respectively, grew improved maize varieties during the 1994/95 season. The hybrid variety, H614 was the most preferred variety in both zones. Ninety-four percent of the adopters purchased maize seed every year. The tobit analysis showed that intermediate zone, extension contact and livestock ownership were significant factors that affected the proportion of land allocated to improved maize varieties, while farm size, hand hoe and farming experience affected the amount of fertilizer used. The results imply the need for increased extension-farmer contacts, development of maize varieties that are tolerant/resistant to stalkborers, cutworms and MSV, as well as support of private sector and NGOs to increase their services to small-scale farmers.Collection: CIMMYT Staff Publications Collection
