The yields of leaf protein from several short-duration crops were determined. The yields depended on species, variety, season, fertilisers and frequency of cutting. Many species responded with increased yields to fertilisers. Between 40 and 63 % protein nitrogen was extractable from cowpea and the plant produced extractable proteinatarateof 11.2kg-ha-dayduringtheinonsoonbut only4.5kg-ha-day during the winter. Good yields were also obtained from the by-product leaves of cauliflower, cabbage and knolkhol. Some varieties of wheat and Tithonia tagetijora were also found promising for leaf protein production.
