Résumé
An experiment to study the effect of season and shrub-grass combinations on the fodder quality of Leucaena (Leucaena leucocephala), Calliandra (Calliandra calothyrsus) and Napier grass (Pennisetum purpureum) was established at Maseno, western Kenya.The species were managed as hedgerows on field bunds in a randomized complete block design with seven treatments and four replications. Fresh and dry leafy biomass assessments, and sample collection were done at two-month harvesting intervals for 18 months. Percent dry matter was determined by oven-drying approximately 500 g of fresh samples at 60 0 C for 48-72 hours. Dried samples were ground to pass a 1 mm sieve and analysed for N (used for crude protein estimation), P, Ca, K, Mg, Zn, Cu and ADF (acid detergent fibre). Statistical analysis was done using SAS 6.04 at ex = 0.05 significance level. Napier grass was highest in fresh and dry biomass productivity. Biomass productivity, however, dropped significantly in the second year. Biomass productivity of shrubs was lower, but was maintained at similar levels throughout the study period. Leucaena was highest in crude protein, Ca and Cu, but lowest in Zn and ADF. Calliandra was highest in K and Mg, but was lowest in crude protein, Ca, P and Cu. Except in the leucaenaNapier grass mixture, where differences were not significant, establishment in shrubgrass combinations caused significant increases
