Conteúdo: | Ireduce inadequacy of family income and enhance rural livelihoods. A Multiple Cropping Technology (MCT) of mixture of maize + groundnut + Cajanus Cajan in the same piece of field was introduced to farmers in Balungu, Gbane, Gbeogo, Sheaga and Yameriga villages in Upper East Region of Ghana. The Traditional Usual Technology involving sole maize or sole legume was the control. A total of 10 farmers per village formed the group of 50. Ridges were constructed using bullock/ camel attached to locally fabricated plough /ridger. Ridges were approximately 50 cm apart. Two seeds of maize were sown per hole at 50 cm apart, giving a total of 80,000 maize plants/ha. One groundnut seed was planted per hole at 50 cm apart with a total of 40 plants /ha. Cajanus cajan seeds were drilled lightly along at a rate of 25 kg ha-1. Maize was planted in the first ridge, groundnut in the second and Cajanus Cajan in the third ridge. The crops were repeated in the same order to cover the field. Soil samples were collected from farmers? field to a depth of 0 ? 40 cm for routine soil laboratory analysis. The soils in the villages are mostly loamy sand, strongly acid to acid in reaction, characterized by moderate organic carbon content with low nitrogen. Available phosphorus moderate with very low to low exchangeable bases, unlike yielded under TUP, yield under MCP increased in the second year. When the second year production in MCT was compared with TUP groundnut was 188 %, 180 %, 142 %, 148 % and 127 %, significantly higher in Gbane, Yameriga, Dbeogo, Balungu and Sheaga respectively. The corresponding values for maize was 402 %, 297 %, 310 %, and 148 5. Cajanus cajan is an additional crop introduced for both livestock and human with the stem used as domestic fuel wood.
