Conteúdo: | The pattern  of leaf growth and death was followed in stands of cowpeagrown in the field at Ibadan, Nigeria. Temperature affected this pattern. Leaf area index increased quicker and leaf  death  started sooner during warm seasons. Individual leaves died while pods at the same nods were filling. The rate of leaf appearance increased  with temperature and the duration of expansion of individual leaves decreased so thata constant number of leaves were expanding at one time. The mean rate of expansion of individual  leaves increased with temperature proportionately more than the duration decreased, hence final leaf size  increased with temperature. Base temperature for leaf appearance  and leaf expansion were 16 and 20oC respectively.
