The variability of climate demands the use of a variety of agronomic strategies and crop choices. Traditional drought tolerant cereal crops such as sorghum and millets are often chosen when drought seasons are anticipated. However, there are certain crops, originating elsewhere, that could help the smallholder farmers increase diversity of crops that can be grown in changed climates. Trials were conducted to test a basket of known and introduced climate smart crops in the field. The cereal crops tested were maize, sorghum, pearl and finger millet, and legumes: tepary bean (Phaseolus acutifolias), cowpea (Vigna unguiculata), Bambara nut (Vigna subterranea), groundnut (Arachis hypogaea) and pigeon pea (Cajanus cajan. A second experiment was conducted to determine the effects of inorganic fertilizer and rhizobium inoculation on the growth and grain yield of field grown tepary bean. Both experiments were laid out in a randomized complete block design with three replications. Due to drought conditions during the growing season, cereal crops could not produce grain yield, as there was no grain filling. Despite this, cereal biomass was 5t ha-1 for maize, followed by sorghum (1.3t ha-1) and millet (1.2t ha-1). Legume crops produced grain with cowpea yielding 568.1kg ha-1 of grain, followed by tepary bean (245.9kg ha-1) and common bean (227kg ha-1). This is important for food, nutrition and health security of smallholder communities. Tepary bean inoculated with rhizobium and had fertilizer applied produced higher grain yield than those without fertilizer or rhizobium inoculant (P£0.05). In conclusion, resource poor farmers, affected by drought effects of climate change, can adopt both cereals and legumes climate smart crops, in order to create food and nutritional security. This is crucial for food and nutritional security of vulnerable households affected by climate change and variability.
