Response of yucca cultivation (Manihot esculenta. Grantz) to the application of mycorrhiza

Abstract

With the objective of evaluating the effectiveness of the inoculations with Arbuscular Mycorrhizal Fungus (AMF), in two yucca (Manihot esculenta. Grantz) varieties under different conditions of the Valley of Guantánamo, several experiments were developed. To achieve this, brown sialitic and fluvisol soils were chosen in correspondence with the cambisol and fluvisol ones in the classification of the Word Reference Bases. (FAO, 2006). A random block- design with four repetitions and two study factors (three towns and three nutritional variants) were used.  The AMF bungs used were Rhizophagus intraradices and Glomus cubense, according to the soil type. The quantity of commercial roots and the yield (t.ha^-1) were evaluated. The results of the experiments demonstrated that the yucca cultivation increased its yield when there were applied efficient bungs of mycorrhizal, with independence of the differences of the climatic and soil conditions of Guantánamo Valley.
