Ramirez Pedroso Joan Arzola Batista Agrociencias Glomus rhizosphere Colonization productivity crude protein In order to evaluate the effect of arbuscular mycorrhizal inoculation on the rehabilitation of a guinea grassland ( Megathyrsus maximus cv. Likoni), an experiment was carried out on Ferralitic Red Leachate soil. A completely randomized design was used with six treatments: control, mechanical rehabilitation with plow and harrow, alone and combined with the applications of 25 t ha -1 of cattle manure and 100 kg ha -1 of N; with the mycorrhizal inoculation of the Glomus cubense species plus the application of 50 and 70 % of the doses of cattle manure and N, respectively, and with mycorrhizal inoculation plus 100 % of the doses of both fertilizers.The dry mass yield, plant height and percentage of grass area, as well as variables related to mycorrhizal functioning (frequency and intensity of colonization and spore content in the rhizosphere) and the contents of Crude protein (PB), neutral detergent fiber (FND) and organic matter digestibility (BMD) were evaluated. Inoculation with G. cubense was successfully integrated into the rehabilitation work. The greatest benefits were obtained when combined with 50 and 70 % of the dose of cattle manure and nitrogen fertilizer that, in that order, produced the greatest benefits in the recovery of uninoculated pasture. The effect of G. cubense was maintained until at least 270 days after its application. 2017 artículo científico 1819-4087 https://www.redalyc.org/articulo.oa?id=193254602004 https://www.redalyc.org/journal/1932/193254602004/ https://www.redalyc.org/journal/1932/193254602004/html/ https://www.redalyc.org/journal/1932/193254602004/193254602004.epub https://www.redalyc.org/journal/1932/193254602004/movil es http://www.redalyc.org/revista.oa?id=1932 Cultivos Tropicales application/pdf Instituto Nacional de Ciencias Agrícolas Cultivos Tropicales (Cuba) Num.4 Vol.38 |
