The objective of the research was to determine the effect of biochar enriched with worm humus and arbuscular mycorrhizal fungi (AMF) on growth and galling of yam plants and M. incognita reproduction. The study was developed under semi-controlled conditions in a biological isolator of the Instituto de Investigaciones de Viandas Tropicales (INIVIT), Santo Domingo, Villa Clara Province, Cuba, in 2022. A completely randomized design with seven replicates was used. The treatments consisted of different combinations of soil, biofertilizers, and biochar, with and without inoculation of a pure population of M. incognita established at the institute. The best development of yam plants was obtained in the treatment where, in the absence of M. incognita, the plants were grown in a substrate containing a mixture of biochar + humus and mycorrhizae as inoculant. It was evident that M. inognita parasitism affected the development of the cultivar 'INIVIT Ñ-2008' because of the decreases produced in plant stem length and fresh and dry matter of the foliar part. The potentialities of incorporating AMF, humus, and biochar in the production technology of D. alata were evidenced by the positive effects on plant growth and development and reduction of M. inognita galling index and reproduction on this cultivar, which was cataloged as a good host and susceptible to this nematode; results which will be corroborated in subsequent field studies.
