Resumo: Maize and bean crops are very important for about 60 to 70% of the population in Angola, being used both for food and as cash-crops. The number of local cultivars is large but productivities of both crops are very small. Final yields depend on the success of crop establishment, which is largely controlled by temperature and water. The aim of this work is to study the combined influence of temperature and soil water on the germination, emergence and early leaf production of local varieties of maize (catete, matuba and SAM3) and beans (catarina, calongupa, ervilha, manteiga e sondeyombwa). Germination and emergence were studied under controlled conditions on a thermal gradient plate. Early leaf production was studied in the field in two types of ferralitic soils, in Chianga (Angola). Thermal-times required for germination, emergence and leaf production were determined and the influence of soil water and soil type was evaluated, together with measures of the spread of germination and emergence. The success of establishment of the varieties is discussed comparatively
