Majority of farmers growing legumes use and recycle seeds from informal sources for the next crop. The quality of such seeds is unknown and usually leads to accumulation of pest, diseases and reduced yields. This study was carried out to determine production practices and quality of soybean seeds obtained from informal sources in Busia County. A survey was conducted to collect information on source of soybean seeds, production and post-harvest handling practices. Seed samples were collected from farmers, local market and agro-dealers. The seeds were evaluated for purity, seed coat damage, germination, vigour and fungal infection. Majority (48%) of farmers in Busia County used farm saved seeds, 29% and 23% used seeds from community based organizations and local markets, respectively. Most of the farmers (92%) used inappropriate threshing techniques like beating with sticks and about 80% of the farmers did not treat seed either before storage or during planting. Majority (68%) stored soybean for three months only. Seeds from informal sources had low purity, higher seed coat damage and infection as compared to certified seeds. The physical purity of seeds from the informal sources did not meet the recommended standard of 98% however their germination was comparable to 75% germination standard. Farmers therefore, should be advised to adopt use of certified seeds and appropriate handling techniques. Keywords: Soybean, seed source, seed quality, seed production practices

Rapeseed meals (RSM), B. campestris L. (cv. Span), derived from a pooled seed source processed in three different Canadian pre-press solvent-extraction processing plants were compared with RSM derived from B. campestris Canadian seed and a B. napus RSM derived from European seed, the latter two meals being processed in The Netherlands. Amino acid, glucosinolate and proximate analyses were conducted. Feeding experiments with mice revealed no differences in weight gains, feed intakes, digestibility of energy or protein, efficiency of feed utilization or protein quality among the three samples of Canadian-processed Span RSM, and the responses equalled those obtained with soybean meal. RSM processed in The Netherlands and derived from Canadian seed equalled the Canadian-processed Span RSM except for a significantly (P = 0.05) lower digestibility of protein. The Netherlands-processed B. napus RSM proved to be inferior and resulted in slower growth and lower protein digestibility. Swine fed the same five RSM samples in typical swine rations but at lower levels of RSM (7.5 and 15.0%) than those (9.1 and 10.1; 19.9 and 22.5; and 30.9 and 34.9%) in the mouse tests showed a reduction in daily gain (P = 0.05) for 15% RSM compared to 7.5% and a tendency for the B. napus RSM from The Netherlands to be inferior (P > 0.05). It is suggested that differences in myrosinase inactivation during processing, the higher oxazolidinethione content characteristic of B. napus RSM, and possible overheating during the toasting phase of RSM production were responsible for the differences observed.
