Abstract

Farmers in the Eastern Province of Zambia are faced with problems common to other parts of the tropics: increased pressure to expand food production leading to accelerated forest clearing, decrease in traditional fallow periods, increased soil erosion, and reductions in soil fertility. Of special concern are shortages of labor during their growing season, a shortage of staple foods during January through March, pest (termite) problems, and seasonal fires. Alleycropping appears able to solve some of the farmers' problems. Both on-farm and experiment station trials were initiated to screen potential agroforestry species. Perennial pigeonpea, Cajanus cajan (L.) Millsp., a species indigenous to the Province, showed particular promise. Cultivars grew over 3 m tall and produced up to 4.8 tons/ha dry matter (in 7 months after pruning) for green manure. Farmers reacted favorably to their experience with the on-farm trials. Ease of establishment and production of food (green pod and grain) make perennial pigeonpea a special agroforestry option in the Province, deserving additional research.
