The drought tolerance of some 900 different strains of cowpea was evaluated in a collaborative research programme between scientists from the Japan International Research Center for Agricultural Sciences (JIRCAS) and IITA. The scientists found that the drought-tolerant strains yielded about one tonne/ha without irrigation during the dry season in the Sudan savannah. Lack of rainfall in the area often results in drought during the ripening stage of the crop, therefore the need for drought-tolerant crops. Later trials in Kano, Nigeria yielded similar results. Some accessions, found to be highly drought tolerant, produced several pods per plant 85 days after sowing. However, seed size, seed coat colour and texture were found to be inadequate and research is continuing to improve these characteristics. Iwao Watanabe/Tomio Terao Div.
