Choosing suitable intercrops prior to pruning Sesbania hedgerows in an alley configuration
- 55 Downloads
In the northern Rwandan Highlands, farming is intensive due to unavailability of land. A study was conducted to choose suitable intercrops with Sesbania for alley cropping prior to cutback of the shrub, a practice that would enable farmers to continuously crop their fields. Potato, pole bean, dwarf bean and maize were tested in 4-m alleys. The study concludes that pole bean is most appropriate while maize is the least preferred intercrop for a 6-month-old Sesbania. Yield losses of intercrops were attributed principally to shading by Sesbania hedges, but competition for nutrients and soil space as well as disease incidence are also possible.
