This study aimed to investigate the influence of different sites of cacao (Theobroma cacao L.) cultivartion, represented by different soils and cropping systems, on biometrics attributes of pods and beans. The 12 study sites are in the cacao region of Bahia, Brazil, in the humid zone. The variation and the statistical differences between the means of these attributes clearly indicate the influence of genotype and environment interaction. Attributes pod wet biomass, beans with mucilage wet biomass and number of beans were positively correlated with the cultivation sites represented by Argisol Red-Yellow Eutrophic cambisolic and Argisol Red-Yellow Dystrophic Cohesive abrupt soils. The highest values of length and dry weight of dry cacao beans correspond to Argisol Red-Yellow Eutrophic cambisolic. The dystrophic soils are related to lower dry weight values of cacao beans. The selection of cacao cropping sites by biometric attributes also highlighted the Argisol Red-Yellow Eutrophic cambisolic and Argisol Red-Yellow Dystrophic Cohesive abrupt soils. Understanding the variability of cacao biometric attributes emphasizes the importance of using technologies for achieving sustainable production of cacao with quality

The experiment evaluated the growth and quality of rootstocks and grafted seedlings using cacao seeds of natural pollination, of the clone TSH-1188 and controlled pollination (TSH-1188 x CCN-10). Assays were carried to compare rootstock and grafted plants. The experimental design was completely randomized with the treatments formed by seed origin, one plant per plot and 30 replications. Pre-germinated seeds were planted in plastic tubes of 800 cm3 filled with substrate and after 90 days the plants were evaluated in plant length (CP) and stem diameter (DC). After 90 days were cut and evaluated: dry biomass of roots (BSR), stems (BSC), leaves (BSF), shoot (BSA), total (BST) and Dickson Quality Index (DQI). For grafting, 30 plants were separated by type of pollination and grafting with the clone BN-34. At 30, 45, 60, 75 and 90 days after grafting were evaluated for plant length (CPT; grafting and rootstock), trunk diameter (DMG) and number of leaves in the grafted stem (NFE). The evaluation of the second assay was performed 90 days after grafting where the plants were assessed for height and diameter, and then cut off to get BST, BSR and IQD. The results showed that seedlings from seeds of controlled pollination showed greater biometric uniformity expressed by IQD, in rootstocks as well as grafting plants with the BN-34 clone
