JOAO, José P; MUTUNDA, Moniz P; TAILA, Amílcar F  and  RIVERA ESPINOSA, Ramón. Potentiality of arbuscular mycorrhizal inoculants applied to cassava crop (Manihot esculenta Crantz) in Kibala, Angola. cultrop [online]. 2016, vol.37, n.2, pp. 33-36. ISSN 1819-4087.

Considering the existence of arbuscular mycorrhizal inoculants applied at low quantities to cassava crop (Manihot esculenta Crantz) and the high mycorrhizal dependence as well as the significance of this crop in Angola, it is essential to evaluate the effectiveness of such products in this country, as a way to obtain an efficient mycorrhizal symbiosis and its benefits on cassava plantations. An experiment was conducted on a Rhodic Distric Ferralsol, in order to appraise the effect of Funneliformis mosseae strain INCAM-2 compared with a control treatment, in a randomized block design with four repetitions and 32 plants per plot. The trial was carried out in a Kibala producers’ farm, South Kwanza province, using Calohendo variety. The inoculant was applied at planting time by coating both propagule tips at the dose of 11, 6 kg ha^-1. The application of F. mosseae provided significant increases (P<0,001) in every variable tested, achieving more vigorous and taller plants, their height raising about 21 %, whereas edible root yields rose from 14, 4 mg ha^-1 in the control to 33, 6 mg ha^-1 in the inoculated treatment and mycorrhizal spores improved eight times at harvest time, indicating the effectiveness of F. mosseae under these edaphic conditions. These results prove the potentiality of applying such mycorrhizal products to cassava crop in Angola
