Abstract
On the poor leached sandy "rweya" soils of the lakeshore area of Bukoba yields of maize and pigeon-peas were greatly increased by the application of farmyard manure or a fertilizer mixture containing N, K and ground limestone. Potash, limestone and farmyard manure gave appreciable residual effects in the two years subsequent to application but not in the third. Production from grassland was increased by the application of sulphate of ammonia, less so by potash and ground limestone, the latter giving its largest responses in the third and fourth years. Severity of cutting greatly influenced responses to fertilizers, responses being lower at the more intensive cutting rates.
