Abstract

Obvious is the fact that globally the climate is changing. Solar energy and water availability are the key factors affecting agricultural productivity in Subtropical Africa. In this paper is presented the global radiation for Owerri, Nigeria (latitude 5.48oN, longitude 7.03oE) between 1985-1997 which has a mean annual value of 76.17 W/m2 per day. With appropriate crop specie selection and management, food production, including poultry output can be boosted in this high solar radiation area. The introduction of solar egg incubator, solar manure dryer and brooder has been strongly advocated.
