“…australis (F. Muell) Bahadur) and Parkia multijuga Benth, reported that shading increases reduced the number and the length of plagiotropic branches, which affects coffee plants' vegetative growth and yield. Colodetti et al (2018) report that the higher NPB produces a higher number of photosynthesizing leaves, which increases the number of photoassimilates, favoring coffee yield.…”

Abiotic stresses cause significant damage to coffee plants' development. Seeking solutions to mitigate them, studies about antiperspirant action have been intensified, for instance, kaolinite, which produces a film of particles with reflexive properties. In this context, this experiment aims to evaluate the effects of applying kaolinite doses in different colors with or without the addition of adjuvant on biometric variables during coffee plants' initial growth. The randomized block design was used with three repetitions in an incomplete factorial scheme with an additional treatment, resulting in 11 treatments and 33 plots. The first factor comprised three kaolinite doses (20, 40, and 60 g); the second factor had two kaolinite colors (white and cream), and the third factor was the absence or presence of an adjuvant, also including an additional treatment (control). The plot consisted of four seedlings of the cultivar IPR 100. It was observed that the plant height (PH), number of plagiotropic branches (NPB), leaf area index (LAI), leaf dry matter (LDM), shoot dry matter (SHDM), root dry matter (RDM), and total dry matter (TDM) presented significant differences. Regarding PH, the dose of 40 g of cream kaolinite increased 7.07 cm more than the control. For LAI, the dose of 40 g with adjuvant had a 97.65 increase. For LDM and TDM, the dose of 40 g of white kaolinite with adjuvant presented respective increases of 5.2 and 12.78 g. The application of white kaolinite with adjuvant increased SHDM by 4.52 g. For RDM, the dose of 40 g of white kaolinite with adjuvant increased 6.51 g more than the control. The dose of 40 g of white kaolinite with adjuvant had a higher effect on the biometric variables.

Currently, one of the most used practices in national coffee production is skeletal pruning, to preserve productive capacity, correct plant architecture, minimize the occurrence of diseases, among others. Also, it reduces the plants diameter, exposing the soil to climatic conditions, erosion, loss of moisture and nutrients, negatively affecting the development of coffee. The use of cover plants intercropped with coffee is presented as a technique to avoid and minimize these problems. Therefore, the objective of this research was to evaluate the effect of cover crops on the chemical and physical characteristics of the soil and the skeleton coffee tree. The experiment took place at Fazenda Boa Esperança, city of Serrania, South of Minas Gerais, from October/2017 to December/2018, in randomized blocks, composed of 8 treatments with and without cover crops. Three replicates per treatment were used, totaling 24 experimental plots, each with 14 plants, being the 10 central considered useful for evaluation. The cover crops contributed to the improvement of nutrient contents in the soil, maintained a better level of humidity and milder temperatures providing a greater development to the skeletonized coffee. They also positively influence weed control, but none could suppress all plants present in the research.

“…A elevação da densidade de plantio é considerada uma prática de manejo favorável ao desenvolvimento dos cafeeiros, pois condiciona a otimização da eficiência de utilização da luz solar e a exploração de maior volume de solo, resultando em maior capacidade de absorção de água e nutrientes (COLODETTI et al, 2018). Porém, quando os cafeeiros são cultivados em associação às árvores, recomenda-se aumentar o espaçamento entre plantas, de modo a evitar sombreamento excessivo, fato que poderia comprometer o processo fotossintético e o alongamento excessivo do ramo ortotrópico.…”

Atualmente, os serviços ambientais relativos aos sistemas agroflorestais (SAFs) estão fundamentados em aspectos qualitativos. Entretanto, para que ocorra a consolidação do pagamentos por tais serviços, os diversos fatores que condicionam os SAFs necessitam ser caracterizados. Este estudo teve comoobjetivos analisar se o estoque de biomassa individual de cafeeiros é afetado porSAFs caracterizados por manejo e arranjos distintos dos cafeeiros arábica e das grevíleas, além de verificar se haveria possibilidade de ajuste de equações alométricas para estimar a biomassa seca dos cafeeiros.O experimento foi conduzido em sistemas de cultivo de café (Coffea arabica L.) sob manejo orgânico e convencional arborizado por grevíleas (Grevillea robusta A. Cunn.), localizados nas regiões do Planalto da Conquista e Chapada Diamantina, Bahia. A partir da determinação da biomassa pelo método destrutivo da simples separação, foram estabelecidas equações de estimativa do estoque de biomassa individual dos cafeeiros. Concluiu-se que o sistema de manejo orgânico e convencional são fatores de menor impacto para o acúmulo de biomassa e carbono em relação à fatores como a densidade de cafeeiros e o arranjo das grevíleas. O menor adensamento de cafeeiros é fator que determina a superioridade dos estoques de biomassa individual.A densidade de cafeeiros e arranjo das grevíleas são fatores que determinam modelos alométricos diferenciados para a estimativa de biomassa dos cafeeiros.
