D.A. Webb.) is a crop of great economic and food relevance in various regions of the world, especially in Mediterranean climate regions. In Brazil, despite its global importance, commercial almond tree cultivation has not yet been registered. The objective of this study was to carry out the preliminary improvement of the almond tree, through investigations that characterize the crop and assess its behavior in tropical conditions in the north of Espírito Santo, with a focus on the adaptation and performance of plants propagated by different methods. The work is structured into four chapters that address different perspectives of this research. Chapter 1 presents a bibliometric analysis of the scientific production on almond tree cultivation, using the Scopus platform to identify research trends, leading producing countries, and the areas of greatest scientific focus. The analysis of 1,160 articles published between 2003 and 2023 revealed the predominance of publications from Spain, the United States, Iran, Italy, and Turkey. The keyword analysis revealed key themes, including genetics, breeding, and water stress. The bibliometric analysis proved to be an effective quantitative tool for understanding the status of scientific research related to almond tree cultivation, providing insights and references for research in the field. In Chapter 2, the adaptation of the almond tree to the tropical climate was evaluated through different propagation methods: seminiferous 1 (almond xi seedlings obtained from seeds), seminiferous 2 (seedlings obtained from seeds with lateral branches removed), and grafting (branches from seminiferous 2 grafted onto the 'Okinawa' rootstock). The results showed that plants propagated by grafting presented better survival rates, height, and stem diameter, highlighting that the use of the 'Okinawa' rootstock was effective in adapting the almond tree to the tropical climate. Chapter 3 addressed the modeling of the leaf area of the '70' almond tree clone, aiming to understand the plant's physiological performance. Twelve mathematical equations (linear, quadratic, power, and exponential) were adjusted and compared to estimate the leaf area based on the leaf dimensions: length (L), width (W), and the product of length and width (LW), using the R software. The quadratic equation, based on the product of length and width, presented the best fit, validated by the root mean square error (RMSE) and mean absolute error (MAE) closest to zero, and the Willmott agreement index (d) closest to one, with the equation given by LAE = 0.0865 + 0.6517LW + 0.0015LW². In Chapter 4, the genetic diversity of almond trees in the northern Espírito Santo was evaluated, considering the effects of vegetative propagation through cloning and seed propagation on plant development and disease resistance. A total of 226 individuals were analyzed, including 64 cloned and 162 seed derived plants. Variables such as the number of shoots, the number of shoots above 100 cm, height, stem diameter, and the incidence and severity of the "bullet hole" disease were measured. Genetic parameters estimated included environmental variance, experimental coefficient of variation, phenotypic variance, genetic variance, broad-sense heritability, genetic coefficient of variation, and variation index. The analysis allowed for the identification of genotypes with greater size and lower disease susceptibility, highlighting their suitability for propagation and use in breeding programs. Through pre-breeding studies, the viability of almond cultivation and its adaptation to the tropical climate of northern Espírito Santo was confirmed, particularly with the use of the ‘Okinawa’ rootstock. These results represent an initial step in the selection of adapted genotypes, paving the way for future research of almond cultivation in Brazil

The occurrence of spontaneous plants and/or weeds in agricultural crops is notorious. Among the herbicides used to control these plants, glyphosate is the active ingredient, one of the main non-selective herbicides used to control weeds in coffee plants. The objective of the first chapter was to use the bibliometric review as it is a planned method, which makes it possible to collect, select and critically analyze the studies. A search was carried out on the Scopus platform with the terms in English: “control*”, weeds*, drift* and glyphosate*. From these records can be obtained between 1992 and 2022, they were selected and analyzed by the VOSviewer software. Highlighting Brazil, the country that publishes the most regarding the researched terms, this is due to the fact of its great worldwide representation in coffee production. The objective of the second chapter was to evaluate which tip and which application rate are favorable for the parameters, density, coverage, DMV, and droplet deposition. The experiment was carried out at the Experimental Farm of the Centro Universitário Norte do Espírito Santo, at the Federal University of Espírito Santo, in a randomized block design with treatments distributed in a 3 x 3 factorial scheme, with three spray nozzles and three application rates, four replicates per treatment. The BD11002 tip, when used at any application rate, resulted in very thick drops, not being a good option, as it had a high flow rate of the syrup. The JDF06 tip, regardless of the application rate, provided better distribution of the product on the target, therefore, being the best option for application

This pest can cause severe production losses, making it a priority for the development of alternative management strategies. Vegetable oils, derived from plant secondary metabolites, exhibit properties that can induce mortality in various organisms, making them promising for pest control, although their effectiveness is limited by volatilization and degradation under field conditions. This study investigated the efficacy of garlic, soursop, and neem vegetable oils, as well as the major compound D-Limonene, both individually and in combination, as well as in emulsified formulations containing all these compounds, for controlling N. elegantalis. Laboratory bioassays were conducted with eggs and first-instar larvae of N. elegantalis, using 2% dilutions in a 0.05% Tween® 80 PS solution. Additionally, emulsions at 15% and 20% concentrations were tested under greenhouse conditions. Mortality rates of eggs and first-instar larvae subjected to spraying were evaluated. The results indicated insecticidal efficacy, with emulsified formulations standing out due to their increased stability and persistence, promoting larval mortality above 50% in greenhouse conditions. The combination of vegetable oils and the major compound proved to be a promising approach for integrated pest management, reducing reliance on synthetic chemical insecticides and promoting more sustainable agricultural practices

The infection caused by PYMoV (Piper yellow mottle virus) in crops and the aggressiveness of the symptoms have a direct influence on the losses that are potentiated when seedlings are affected. Although viruses can be asymptomatic, they can be identified mainly by the symptoms of mosaic, whitening of the veins, and fruit reduction. Methods that help in early and reliable detection can have direct benefits to growers. The objective of this work was to evaluate the occurrence of PYMoV in commercial black pepper nursery plants using the PCR technique. Plant tissues from 77 plants (symptomatic and asymptomatic) were collected from a nursery in the region of Jaguaré-ES. After extraction of total DNA, the samples were submitted to PCR reaction with specific primers to detect part of the viral genome. Only 5 plants (6.5%) tested positive for the presence of the virus, indicating a low incidence of the virus in the evaluated nursery. Among the plants analyzed there were cases in which visual symptomatology was confirmed by PCR, cases in which the negative PCR indicated that the plant was not contaminated or that the symptom observed would be indicative, for example, of a possible nutritional deficiency. We conclude that the PCR technique was efficient for the molecular identification of PYMoV in the samples evaluated. Work of this nature can bring direct benefits to producers, contributing to minimize years and losses to nurserymen and black pepper producers
