Abstract: Brazil has coffee growing as one of the main economic activities of its agribusiness, however, climate change imposes serious challenges on farmers to maintain agricultural production levels in the future, so afforestation becomes essential as a means of protection against extreme effects. of the environment. The objective of this study was to verify whether the different distances between coffee and cedar can change the morpho-physiological characteristics of the coffee tree. The experiment was carried out in the municipality of Barra do Choça -BA, on a private property, in an area composed of Australian cedar trees (Toona ciliatta M. Roem) arranged in two subsequent rows, with a spacing of 19.8 × 3 m, and arabica coffee var. Red Catucaí (3.3 × 0.5 m). The treatments were defined by the distance of the coffee trees in relation to the first row of the cedar row (T1: 3.3 m; T2: 6.6 m; T3: 9.9 m; T4: 13.2 m and T5: 16.5 m m). In August/2021, height, number of plagiotropic branches, stem diameter and SPAD index of coffee were carried out. The distance from the analyzed row affects the morphology of the coffee trees, promoting an increase in the height of the coffee tree and smallest stem diameter. Light restriction provides an increase in chlorophyll concentrations in coffee trees located close to cedar rows.
