• Abstract:

  This experiment aimed to evaluate the production of elite cassava genotypes (Manihot esculenta Crantz) resistant and tolerant to adverse and noteworthy factors in productivity, due to the fact that it is an important crop for small producers in Mozambique, both domestic and industrial. The elite cassava genotypes came from five African countries (Tanzania, Malawi, Kenya, Uganda and Mozambique), at the Umbeluzi Agricultural Station, in the district of Boane in the province of Maputo in the period 2015/16, where the design was used. of incomplete blocks with twenty-seven genotypes planted in seven blocks and three replications, in which each block received four treatments. The variables studied were: plant height (ALTPL) in meters, number of roots/plant (NURPL), commercial root production (PRACO), shoot biomass yield (BIOPA), tuberous root yield (RENRA), index yield (INDCO) in percent, dry matter (DM) in percent. Results of the research carried out through the RStudio statistical package, show that there were significant differences of cassava genotypes on yield, the highest being achieved with the KE01 genotype that presented 32.03t.ha-1, followed by the UG01 genotypes (29.25t. ha-1), UG05 (25.56t.ha-1), KE05 (24.69t.ha-1), MW04 (24.42t.ha-1), MW03 (24.09t.ha-1), UG04 (22.80t.ha-1), TZ08 (21.68t.ha-1), KE04 (19.80t.ha-1), UG02 (19.75t.ha-1) and MZ123 (18t.ha-1 ). The average dry matter among the genotypes studied ranged from 21.89% (UG03) to 33.09% (MZ125); the harvest index of the evaluated genotypes ranged from 4.96% (KE03) to 39.83% (KE01).
