Soya Beans as a Potentially Valuable Crop for Agricultural Diversification in Central Uganda
(1970) Rubaihayo P. R.; . Leakey c. L. A
Auckland [1, 2, 3,4] has previously described a successful selection and breeding programme for soya beans at Nachingwea, Tanzania,which led to the release of new cultivars considered to be well adapted to areas from 5-100 S. latitude and altitudes of less than 3,000 ft. His cultivars also proved to be well suited in the similar latitude and altitude conditions in the Solomon Islands, and his programme is probably the most successful soya bean breeding programme yet carried out in latitudes of 10° or less. Mean experimental yields of the most productive new cultivars over four or five-year periods were of the order of 1,980 kg/ha. The highest yield recorded was 3,040 kg./ha. from HLS 219 at 3,800 ft. above sea level and 10° 50' S. Weiss [5] and Gray [6] have described trials of some soya bean cultivars in western Kenya where the Kenya Government have for some years been interested in developing commercial cultivation of the crop. Weiss was only able to obtain 15 cultivars for trial and failed to obtain any yields over 1,680 kg/ha. except by the application in one trial of t oz. of the growth substance triiodobenzoic acid per acre. Gray using 12 in. row spacing and the cultivar "Belgian Congo" attained encouraging yields of about 2,300 kg/ha. at Kisii in 1965 .
