Description A pigeonpea fallow-maize crop rotation trial was carried out over a period of 4 seasons in western
Kenya. The trial compared six high altitude long duration pigeonpea varieties i.e. ICEAP 00020,
ICEAP 00040, ICEAP 00048, ICEAP 00053, ICP 9145 and ICP 13076 and a medium duration
variety i.e. ICP 13211 for productivity, post fallow maize crop yield and financial returns
indicators. Long duration pigeonpea varieties take 140-180 days to mature while medium duration
varieties take >200 days to mature. Continuous maize cropping acted as a control. Depending on
the variety, pigeonpea grain yield ranged between 1.3 and 1.9 t ha-1. Post fallow maize grain yield
from each of pigeonpea variety plot was approximately 3 fold higher than yield from continuous
maize plots. The medium duration pigeonpea plots yielded significantly higher maize grain than
the long duration (ICEAP 00053, ICEAP 00040) pigeonpea variety plots. Relative to the control,
incremental returns to land were highest for medium duration pigeonpea fallow plots (619
USD ha-1) and lowest for ICEAP 00040 fallow plots (305 USD ha-1). We estimated that by
selecting an appropriate pigeonpea variety for a fallow-maize rotation system, a household could
produce sufficient food for consumption and remain with a surplus of approximately 2.8 tons for
sale. For widespread adoption of pigeonpea based technologies in western Kenya, there is a need
for policy improvement on issues related to improved seed production systems, cost of fertilizers,
extension services, and market for the end products.
