Arrière-effet du Stylosanthes guianensis sur la production et la composition chimique de Brachiaria ruziziensis en Adamaoua, Cameroun

Studies carried out at the Wakwa Animal Research Station showed that mineral fertilizers significantly improved the forage production of pastures. However, given their cost, availability problems and the poor economic means of livestock farmers, the adoption of this practice is not easy to extend in the field. In this light, other methods of cropping that can increase forage production were envisaged. Stylosanthes guianensis (Aubl.) S.w, cultivar FAO 46004 and Brachiaria ruziziensis Germain and Evrard association were performed in two plots. Results of the cultivation of Brachiaria ruziziensis on a plot which had been seeded two years earlier with Stylosanthes guianensis revealed a 20 percent increase in the yield of Brachiaria ruziziensis. No significant (P more than 0.05) difference was observed in the proximate analysis of the forages from the two plots. This practice, although not a substitute for fertilization, might lead to a reduction in the quantity of fertilizers to supply
