Study of changes in the herbaceous vegetation of rangeland at the Gounjel ranch, Adamawa, Cameroon ; Estudio de la evolución de la vegetación herbácea de zonas forrajeras del rancho Gounjel (Compañía pastoral), Adamaoua, Camerún ; Etude de l'évolution de la végétation herbacée des parcs à foin du ranch de Gounjel (Compagnie pastorale), Adamaoua, Cameroun
A study was carried out at the end of October 1982 to compare plots that were left fallow at different times during the rainy season and slashed during the dry season after the passage of a disc harrow, and those subject to continuous grazing (the control). Vegetation sampling was done according to the sigmatist method of Braun-Blanquet. The forage production, obtained by cutting the aerial biomass at 10 cm from the soil, was subjected to Student’s t-test. The results show that a fast (2 to 5 years) and important modification as well as true improvement in the pastoral flora (disappearance of u... Mehr ...

A study was carried out at the end of October 1982 to compare plots that were left fallow at different times during the rainy season and slashed during the dry season after the passage of a disc harrow, and those subject to continuous grazing (the control). Vegetation sampling was done according to the sigmatist method of Braun-Blanquet. The forage production, obtained by cutting the aerial biomass at 10 cm from the soil, was subjected to Student’s t-test. The results show that a fast (2 to 5 years) and important modification as well as true improvement in the pastoral flora (disappearance of unpalatable species and the appearance of good forage species) of degraded pastures can be brought about by this management system. This technique can therefore be used for the regeneration of this type of pasture. ; A fines del mes de octubre de 1982, se llevó a cabo un estudio, cuyo objetivo era el de comparar parcelas con prohibición de pastoreo en diferentes momentos de la estación lluviosa y segadas durante la estación seca, previa pulverización con discos, contra parcelas sometidas a pastoreo continuo (testigos). Los listados se efectuaron de acuerdo al método sigmástico de Braun-Blanquet. La producción forrajera, obtenida mediante la siega de la biomasa aérea a 10 cm del suelo, fue sometida al test T (Student-Fisher). Los resultados demuestran que el manejo de la parcelas ocasiona una rápida (2 a 5 años) e importante modificación, así como una mejora real de la flora pastoral de los pastizales degradados: desaparición de las especies poco o no apetitosas, aparición de buenas especies forrajeras. Por lo tanto, esta técnica puede ser utilizada para la regeneración de este tipo de pastizales. ; Une étude a été conduite, fin octobre 1982, afin de comparer des parcelles mises en défens à différentes époques pendant les saisons de pluies et fauchées pendant les saisons sèches après passage du pulvériseur à disques, à des parcelles soumises à une pâture continue (témoins). Les relevés de végétation ont été réalisés selon le ...
