Autor: Abigael Otinga Nekesa, Beatrice A. Were, J.R. Okalebo, Janet Kemuma Ogega

Publikováno v: Turkish Journal of Agriculture: Food Science and Technology, Vol 6, Iss 2, Pp 195-198 (2018)

Food insecurity in Sub - Saharan Africa (SSA) is on the rise due to soil fertility depletion and in Kenya, Nitrogen (N) is one of the widely deficient nutrients. Biological nitrogen fixation (BNF) can replenish N into the soil system. A study was car

Survival and Soil Nutrient Changes During 5 Years of Growth of 16 Faidherbia albida Provenances in Semi-Arid Baringo District, Kenya

Autor: S. Gudu, J.R. Okalebo, O. G. Dangasuk

Publikováno v: Innovations as Key to the Green Revolution in Africa ISBN: 9789048125418

Farmers throughout Africa for improving soil fertility and crop yields have long used Faidherbia albida. Increase in yield from crops grown below the trees has been attributed to increased nutrients. Sixteen provenances of F. albida were planted in a
