Descripción
Avaliação da cultura da mandioca (Manihot esculenta Crantz) em sistema e policultivo: Yields and survival rates will be presented for three manioc cultivars(Pao IM 226, Vinagre IM 157 and Mandioca IM 116), planted between the rows in two mixed cropping systems, which were treated by application of 30% or 100% of the recommended fertilizer dose and inoculation or not with mycorrhizal fungi spores. With regard to yield, there is no statistically significant difference between the treatments viewed in isolation. However, there are statistically significant differences between the cultivars Pao (10.6 tons/ha) and Vinagre (5.5 tons/ha) in system 2; between 100% fertilization (5.2 tons/ha) and 30% fertilization (3.7 tons/ha) in system 3, and between the Pao cultivars in systems 2 (10.6 tons/ha) and 3 (5.4 tons/ha). The resprouting rates of the cutting were considered to be low. There was no statistically significant difference in survival rates between the treatments. The yields are lower than those normally obtained in the region, i.e., 20.0 tons/ha for Pao, 14.0 tons/ha for Vinagre and 16,0 tons/ha for manioc in monoculture.
