Description
Brachiaria grass is an important tropical forage of African origin with desirable attributes of agricultural and environmental significance. Brachiaria has been extensively cultivated as a pasture across the tropics except in its endemic provenance of Africa. In 2013, a collaborative research program was initiated in Kenya and Rwanda with the aim of improving the availability of quality livestock feeds adapted to drought and low fertility soils using Brachiaria. The outcomes sought were increased livestock productivity leading to improved farmer income and the development of seed production opportunities. The program has identified five preferred cultivars, and four of them are currently being evaluated on-farm by over 2000 small-holder farmers in Kenya and Rwanda for livestock productivity. Preliminary milk production data has shown a 15 to 40% increase in milk production in Kenya and an average increase of 36% in Rwanda. The substitution of Napier grass by Brachiaria in the feed has increased average daily body weight gain of cattle by 205g during a 12 week period. Kenyan farmers reported increased on-farm forage availability by three months after Brachiaria introduction. The program has also worked to determine the role of endophytes and plant associated microbes for the improvement of biomass production and adaptation of Brachiaria to biotic and abiotic stresses. A diverse group of fungi and bacteria were isolated, identified and characterized, and the role of these microbes on plant growth and plant pathogen suppression is being investigated. This paper discusses the rationale for selecting Brachiaria as potential forage for eastern Africa and highlights current achievements, and identifies areas for future research.
