Abstract Edaphoclimatic conditions determine variations in availability of water and nutrients, susceptibility to erosive processes and expression of the genetic potential of the cactus pear. Thus, management systems consistent with environmental specificities influence the expression of the plant's structural characteristics, its yield and the forage quality. Therefore, the aim of this study was to characterize the soils of traditional cactus pear production systems and to correlate it with the productivity and mineral and chemical composition of cladodes in agroecosystems in the semiarid region of Bahia. For that, five stratified agroecosystems were selected based on the distinction of the characteristics of soils, vegetation, relief, altimetry, typology of producers and production systems of cactus pear. The crop yield data were obtained based on the harvest of cladodes from all plants in each repetition, carried out between August and September 2017. Each of the three replications, in the 20 properties, had an average useful area of 14 m2 and an average quantity of 16 plants. For the evaluation of bromatological characteristics, at the time of collection, an average of 34 samples of cladodes were collected per repetition, with approximately 40 g each. Soils with better natural fertility, that is, with higher values of sum of exchangeable bases (SB), effective cation exchange capacity (t), cation exchange capacity at pH 7.0 (T) and base saturation index (V), do not necessarily determine better structural performance of plants compared to less fertile soils, but they influence higher productivity. Other factors associated with management and climate influenced plant structure, productivity and chemical quality of cactus pear cladodes.

巴伊亚半干旱地区农业生态系统中'Gigante'仙人掌梨的土壤属性及品质和产量

摘要 土壤环境条件决定了水和养分的可用性、对侵蚀过程的敏感性以及仙人掌梨遗传潜力的表达的变化。因此，符合环境特性的管理系统会影响植物结构特征的表达、其产量和草料质量。因此，本研究的目的是表征传统仙人掌梨生产系统的土壤，并将其与巴伊亚半干旱地区农业生态系统中枝条的生产力和矿物和化学成分相关联。为此，根据仙人掌梨的土壤、植被、地形、高度、生产者类型和生产系统特征的区别，选择了五个分层的农业生态系统。作物产量数据是根据 2017 年 8 月至 2017 年 9 月期间在每次重复中从所有植物中收获的枝叶获得的。 20 个属性中的三个重复中的每一个的平均有用面积为 14 平方米，平均数量16 株植物。为了评估溴学特征，在收集时，每次重复平均收集 34 个枝条样本，每个样本约 40 g。具有较好天然肥力的土壤，即交换碱总和 (SB)、有效阳离子交换容量 (t)、pH 7.0 时的阳离子交换容量 (T) 和碱饱和指数 (V) 的值较高，不一定决定与不太肥沃的土壤相比，植物具有更好的结构性能，但它们会影响更高的生产力。
