[online]. 2020, vol.38, n.3, pp.406-417.  Epub 08-Jun-2021. ISSN 0120-9965.  https://doi.org/10.15446/agron.colomb.v38n3.85069.

This study aimed to evaluate the efficiency with which smallholder maize farmers use their input resources such as land, labor, capital, fertilizers, herbicides, pesticides, and improved seed in maize production. The study used the multi-stage sampling technique to collect cross-sectional data from 600 smallholder maize producers from the northern, Brong-Ahafo, eastern, and central regions of Ghana. This study employed the marginal value product (MVP) to marginal factor cost (MFC) ratio (MVP/MFC) of the input resources. The results revealed an increased return to scale, meaning smallholder maize farmers in the pooled sample and the studied regions should enlarge their production scale by about 3.2%, 2.2%, 7.6%, 6.8%, and 2.8%, respectively, to maximize productivity. The results also revealed that resource inputs like fertilizer, herbicides, pesticides, improved seed, and land were underutilized. Therefore, these resources need to be increased if smallholder maize farmers in the pooled sample want to be efficient in their production. Labor and capital were over-utilized and needed to be reduced to increase efficiency in the farmers' maize production.
