The fruit growing activity is of great importance for Brazilian agribusiness as the country is the third largest fruit producer in the world. Despite this notability, the fruit market presents obstacles especially related to international trade. Thus, the present study sought to determine the positioning and evolution of Brazil in the international fresh fruit market. Data used in the research were obtained from the Food and Agriculture Organization of the United Nations (FAO) (1986 to 2017) and the World Bank (2018), using metrics of export flow, quantity and income of countries related to the main fruits exported by Brazil in the first quarter of 2020. Data were manipulated, transformed into figures and graphs for better visualization of information. The Brazilian position in the in the ranking of fresh fruit exports was not very dynamic during the evaluation period, being dependent on the demand from high-income European countries.

Barueiro (Dipteryx alata Vog.), a fruit tree native to the Brazilian cerrado, has aroused the interest of producers and consumers due to its almond highly appraised and valued by local markets. To obtain quality barueiro seedlings, balanced fertilization is required, with special attention to the supply of phosphorus and nitrogen, essential for seedling growth and establishment in the field. The aim of this study was to evaluate the growth of barueiro seedlings produced with different phosphate and nitrogen concentrations in Nova Xavantina – MT. The experiment was conducted at the seedling nursery of the Mato Grosso State University (UNEMAT), Campus of Nova Xavantina - MT, from December 2017 to April 2018. The experimental design was randomized blocks (DBC), in a 5 × 2 factorial scheme, corresponding to 5 phosphorus concentrations and 2 nitrogen concentrations, with 10 treatments, 4 blocks and 10 plants per plot, totalizing 400 seedlings. The applied concentrations were 0, 150, 300, 450 and 600 mg kg-1 P2O5 and 0 and 250 mg kg-1 N. The following variables were evaluated: plant height, plant stem diameter, number of leaves, number of leaflets, fresh and shoot and root dry mass and Dickson’s Quality Index. Significant interaction between phosphorus and nitrogen concentrations for all traits evaluated was observed, except for root dry mass. The greatest growth of barueiro seedlings was obtained when the highest phosphorus concentration (600 mg kg-1de P2O5) was used, associated to nitrogen fertilization of 250 mg kg-1. There was no isolated effect of phosphate fertilization on the growth of barueiro seedlings without nitrogen application.

Brazilian fruit farming stands out as a strategic activity for the country’s economy, food security and sustainable development. With a wide diversity of tropical, subtropical and temperate species, Brazil has consolidated itself as the world’s third largest fruit producer, with an annual production of 43 milliontons and a Gross Production Value (GPV) of R$ 75 billion in 2023, benefiting from favorable climate conditions, vast territorial extension and abundant natural resources. The objective of this study is to present an updated overview of Brazilian fruit farming, highlighting its economic, social and environmental relevance, in addition to discussing the challenges and opportunities for strengthening the sector. Oranges lead Brazilian fruit production, followed by bananas, açaí,grapes and pineapples. The sector supplies the domestic market with fresh and processed fruits, and stands out in exports, mainly of mango, melon, papaya, grapes,lemons and limes, reaching demanding markets in Europe, North America and Asia.These are the result of investments in technology, sustainable management and innovation. Despite its success, the sector faces challenges such as climatechange, pests, low adoption of technologies in some regions, irregularities inproduction, limitations in transportation infrastructure and high tax revenue. Nevertheless, Brazilian fruit farming plays an essential role in generating jobs, income and sustainable development, consolidating Brazil as one of the biggest players in global agribusiness.

Brazilian banana farming is one of the most important agricultural activities in the national scenario and can be highly productive and economically profitable for producers who invest in technology. The objective of this work was to compare the economic viability of two different fertilization managements in the cultivation system of 1st -cycle ‘Prata Anã’ Gorutuba bananas. The conventional fertilization treatment (CM), adopted by the producer (control), was compared with the alternative treatment: conventional management + 3 soil conditioners + 1 biostimulant (CM + 3SC + 1B). The four products selected for the alternative treatment were oyster shell limestone, Celtonite, Lithothamnium calcareum and Acadian. The application of the four products in the CM + 3SC + 1B treatment provided satisfactory results on crop performance, mainly due to the increase of 4.032 tons ha-1. The CM+3CS+1B alternative management was more economically viable than CM, as the total operational cost (1st + 2nd year) of the alternative management was 6.71% higher compared to the conventional management; however, the alternative treatment productivity was 28.08% higher. The cost to produce one ton of bananas was R$ 2.456,91 in the conventional treatment and R$ 2.047,07 in the alternative treatment, which represents a 16.68% reduction in the average cost, indicating the economic feasibility of this treatment.

Pesquisas sugerem que o raleio químico, com concentrações adequadas de fitorreguladores, deve ser utilizado por mais de um ano, a fim de melhorar a qualidade de tangerinas 'Ponkan'. Diante do exposto, o raleio químico foi aplicado por dois anos, neste estudo, com o objetivo de avaliar as características físico-químicas de tangerinas 'Ponkan' (Citrus reticulata Blanco). A avaliação foi realizada em pomar de tangerineiras com doze anos de idade, enxertadas sobre limoeiro 'Cravo' (Citrus limonia Osbeck), no espaçamento de 6,0 m entre as linhas e de 3,0 m entre as plantas. As plantas foram pulverizadas com quatro concentrações de Ethephon (200 mg L-1; 400 mg L-1; 600 mg L-1; e 800 mg L-1), após o período de queda fisiológica das frutas, quando estas estavam no estádio de desenvolvimento entre 25,0 mm e 30,0 mm de diâmetro transversal, em janeiro de 2009 e janeiro de 2010. Plantas sem pulverização foram utilizadas como controle. O delineamento experimental foi em blocos casualizados, com quatro blocos e quatro plantas por parcela. Houve interação entre as concentrações de Ethephon e os anos de aplicação do raleio para percentual de raleio, número de frutas, massa, diâmetro transversal e longitudinal, teores de sólidos solúveis, acidez titulável, ratio e açúcares totais. Não foi observada influência das concentrações de Ethephon para o rendimento de suco. A regularidade do raleio químico, com a aplicação de Ethephon, aumentou a massa, diâmetro transversal e longitudinal, sólidos solúveis e ratio das tangerinas 'Ponkan'.
