Evaluation de la productivité énergétique de parcours camelins, wilaya d’Ouargla, Algérie

摘要

In order to evaluate the energy productivity of the camel's rangelands, we used the Chehma equations (2008) to estimate the aerial phytomass of perennial species. The measurements were taken at El Alia rangelands, Ouargla (South-East of Algeria), during the spring in 2 stations and 6 sub-stations in each. The results showed that there were 14 forage species spread over 10 botanical families mainly Amaranthaceae = Chenopodiaceae (35.7%). The phytomass produced varies according to species and stations, with an average of 2458 kg / MS / ha. The total energy productivity of the course was 1125 UFL / ha and 1077 UFV / ha ; Salsola tetragona showed the best values (322 UFL and 290 UFV). So, in the Saharan environment, the energy productivity of rangelands remains appreciable. This gives it an important pastoral interest.
