“…Tree litter can release phytotoxic exudates into the soil, restricting germination (Rawat et al, 2017) and growth vigor of surrounding plants (Garima and Devi, 2017). Limonoids (De Leo et al, 2018;Zhang et al, 2019) and several phenolic compounds (Samaradivakara et al, 2016;Tandon and Sand, 2016) predominate among metabolites of Australian red cedar. Limonoids extracted from several species belonging to the family Meliaceae have phytotoxic properties that inhibit germination of many crops, such as maize, common bean, gourd, and lettuce (Parmar et al, 2019).…”

Agroforestry systems are important forms of sustainable farming, providing several ecosystem services. However, characterization and management of factors such as thermal and light heterogeneity, as well as interactions between trees and coffee plants, are determinants for achieving the desired sustainability. This study aimed to verify whether different distances between Coffea arabica L. and Australian red cedar can change soil and microclimate characteristics and how they alter morphological and physiological attributes of coffee plants over the rainy season and a prolonged drought period (veranico) in Summer. The trial was carried out in the municipality of Barra do Choça, in an area with Australian red cedar trees (Toona ciliata M. Roem), distributed in two hedges, spaced 19.8 × 3 m apart, in a northeast-southwest direction, and coffee plants var. Catucaí Vermelho (3.3 × 0.5 m). Treatments were defined by the distance between the coffee plants and the first row of the Australian red cedar hedge (3.3 m, T1; 6.6 m, T2; 9.9 m, T3; 13.2 m, T4; 16.4 m, T5). Morphology and physiology of coffee plants, soil temperature, incident light on coffee plants, and the allelopathic potential of Australian red cedar leaf extracts were assessed in the wet and dry season of the 2016–2017 Summer. Temperatures fluctuated less in experimental units close to the hedge. The reduced growth of coffee plants close to the hedges was related to self-shading associated with light restriction by the trees. The experiment showed the allelopathic potential of Australian red cedar leaves.
