abstract: Predicted warmer climates are likely to negatively affect production systems and expose smallholder
farmers in sub-Saharan Africa, whose adaptive capacity is limited mainly due to poverty, to food
insecurity. We studied the performance of selected varieties representing short, medium and long duration
growth periods of four crops (maize (Zea mays L.), sorghum (Sorghum bicolor L.), groundnut (Arachis
hypogaea L.) and cowpea (Vigna unguiculata L.) at two pairs (wet and dry) of 2050s climate analogue sites.
Climate analogues, based on 30 years metereological data, were identified in smallholder areas of
Zimbabwe. The sites were Kadoma (722 mm annual mean rainfall; 21.8oC annual mean temperature) which
was the higher-temperature analogue site for Mazowe (842 mm annual mean rainfall; 18.2oC annual mean
temperature) for wetter areas, and Chiredzi (541 mm annual mean rainfall; 21.3oC annual mean
temperature) which was the higher-temperature analogue site for Matobo (567 mm annual mean rainfall:
18.4oC annual mean temperature) for drier areas. First season (2011/12) results showed that for the wetter
pair, maize and groundnut grain yields were significantly higher at the cooler site (Mazowe). Sorghum
yields were not significantly different between the sites and there was no grain yield for cowpea at the
cooler site due to a fungal disease. Varietal yield differences were only significantly higher (P<0.05) at the
cooler site for groundnut where the short duration variety had the highest yield (3809 kg/ha) and the
medium duration variety the lowest yield (1420 kg/ha), compared with 140-355 kg/ha at the hotter site
where growth was poor for all varieties. For the drier sites, maize, sorghum and cowpea grain yields were
higher at the cooler site (Matobo) compared with the hotter sites (Chiredzi) but varietal differences were
not significant. Results for the second season (2012/13) will be presented.
