Autor(es): VIAL, P. S.; ALBERTO, N. J.; CHEQUETTO, E.; GRÉLLA, W. C.; MAGEVSKI, L. da S.; CARRAFA, M. P.; SCHMILDT, E R.; GONÇALVES JÚNOR, D. H.; PARTELLI, F. L. Descrição: This study evaluated the morphological development of 23 Coffea canephora clones in Espírito Santo to identify materials with superior vigor and quality for commercial and breeding purposes. Seedlings from cuttings were arranged in a completely randomized design with ten replicates and assessed at the commercial dispatch stage. Shoot and root growth, biomass, leaf area (LA), Dickson Quality Index (DQI), structural ratios (shoot/root ratio, SRR; height/diameter ratio, HDR), and anatomical traits were measured. Data were analyzed using analysis of variance with Scott Knott clustering, Pearson correlation, and Principal Component Analysis (PCA). Significant variability was observed among clones. Clones 88, VR3, 8, and LB33 showed the highest stem diameter (SD), total dry mass (TDM), LA, and DQI, with balanced shoot and root development. Leaf area correlated strongly with SD, number of leaves (NL), biomass, and DQI, confirming its role as a seedling quality indicator. PCA identified two groups: a high-performance group with greater vigor and biomass, and a lower-performance group including clones 7, MR04, and VR4. The convergence of methods confirms the robustness of the results. Overall, clones 88, VR3, 8, and LB33 demonstrate superior agronomic potential at the seedling stage, offering promising options for nurseries, growers, and clonal selection programs.

Autor(es): BARRAQUI, N. S. G.; RODRIGUES, P. F. A.; AMARAL, A. G. G.; CÂMARA, M. P. S.; VENTURA, J. A.; FRANÇA, H. S. Descrição: Schinus terebinthifolia, a plant which is widely distributed throughout South America, is commonly known as pink pepper or Brazilian peppertree. Its essential oil has demonstrated antioxidant, wound-healing, antibacterial and antifungal properties. To enhance its antifungal potential, nanoemulsions of S. terebinthifolia essential oil were prepared to assess their antifungal effect on Colletotrichum plurivorum, the causal agent of anthracnose in papaya. To achieve this, in vitro assays were evaluated to determine the minimum inhibitory concentration (MIC) of the nanoemulsion using 96-well microplates and petri dishes. Subsequently, the most effective concentrations were tested in vivo on papaya fruits under both preventive and curative conditions. The in vitro results indicated that the S. terebinthifolia essential oil nanoemulsion inhibited the growth of C. plurivorum. In vivo evaluations on papaya fruits inoculated with C. plurivorum revealed that the nanoemulsion reduced both lesion size and disease incidence, demonstrating preventive and curative effects. The use of S. terebinthifolia essential oil nanoemulsions proved to be an innovative and effective post-harvest strategy for the control of papaya anthracnose at concentrations of 0.13% and 0.26%, showing promising results for the management of C. plurivorum infections.

Autor(es): SILVERIO, T. C.; REIS, G. A. dos; BINDA, F. F.; DESTÉFANI, W. C.; POLEZ, F. R.; FREITAS, I. L. de J.; XAVIER, G. R. Descrição: Bio-inputs have become vital in agriculture, helping to boost productivity, improve soil health, reduce greenhouse gases, and lower production costs. This systematic review summarizes the evidence on using bio-inputs in black pepper (Piper nigrum L.) cultivation, focusing specifically on the live stake system with Gliricidia sepium. Fourteen primary studies (1985 2025) were included after searching five scientific databases following PRISMA 2020 guidelines. The evidence shows that Azospirillum can cut mineral nitrogen fertilization by up to 25% without affecting yield. Bacillus and Trichoderma are key in controlling soil-borne pathogens, while live stakes with Gliricidia sepium lowered establishment costs by about 27% while keeping crop productivity steady. However, important gaps still exist, such as the lack of standardized protocols, unclear optimal doses, and few studies on Ascophyllum nodosum in P. nigrum. The conclusion is that combining bio-inputs with the live stake system offers a sustainable option for black pepper farming, reducing reliance on chemicals and promoting low-impact farming practices. O uso de bioinsumos tem se tornado essencial na agricultura, contribuindo para a elevação da produtividade e da qualidade do solo, para a mitigação de gases de efeito estufa e, sobretudo, para a redução dos custos de produção. Esta revisão sistemática sintetiza evidências sobre o uso de bioinsumos no cultivo da pimenta-do-reino (Piper nigrum L.), com ênfase no sistema de tutor vivo com Gliricidia sepium. Foram incluídos 14 estudos primários (1985 2025) após uma busca em cinco bases de dados científicas, seguindo as diretrizes PRISMA 2020. As evidências reunidas mostram que Azospirillum permitiu reduzir a adubação nitrogenada mineral em até 25% sem queda na produtividade. Bacillus e Trichoderma destacaram-se no controle de patógenos do solo, enquanto o tutor vivo com Gliricídia sepium reduziu os custos de implantação em cerca de 27%, mantendo o rendimento da cultura. Ainda assim, persistem lacunas importantes, como a ausência de protocolos padronizados, a definição de doses adequadas e a falta de estudos com Ascophyllum nodosum em P. nigrum. Conclui-se que a integração de bioinsumos ao sistema de tutor vivo constitui uma alternativa sustentável para a pipericultura, com potencial para reduzir a dependência de insumos químicos e consolidar práticas agrícolas de baixo impacto ambiental.

Autor(es): FERREIRA, T. R.; OLIVEIRA, V. de S.; JESUS, J. M. de; ALVES, F. C.; POLONINI, G. T.; BRANDÃO, C. T. F.; FONSECA, L. F.; ARAÚJO, E. L.; ARANTES, L. de O.; SANTANA, E. N. de.; FALQUETO, A. R.; SCHMILDT, E. R.; DOUSSEAU-ARANTES, S. Descrição: Water deficit is one of the main limiting factors in agricultural production, affecting the growth and photosynthetic performance of plants. The aim of this study was to evaluate the effects of foliar applications of melatonin, A. nodosum and L. calcareum on black pepper, Bragantina , subjected to three cycles of water deficit, on physiological performance, carbohydrate allocation and vegetative growth. The results showed that the applied solutions contributed to the recovery of damage caused by water stress. The first cycle of water deficit affected the electron transfer quantum yield, resulting in the reduction of φP0 and PIABS. However, the damage to the photosynthetic apparatus was recovered in subsequent cycles. Water stress reduced chlorophyll indices, possibly as a strategy tominimize photo-oxidative damage. Plants treated with melatonin and L. calcareum maintained a stable leaf expansion rate and showed greater water recovery, standing out in the second and third cycles of water deficit.
