-The 'Roxo de Valinhos' fig is one of the most widely grown varieties in the world, however, there are still few studies on the phenology and yield of fig trees, especially in semi-arid regions. This study evaluated the phenology and yield aspects of the 'Roxo de Valinhos' fig cultivar in Western Potiguar. The experiment was carried out from July to December 2015 in the didactic orchard of the Federal Rural University of the Semi-Arid, UFERSA. The following phenological aspects were analyzed: pruning at the beginning of budding, emergence and maturity of the first fruit, beginning of harvest, length and diameter of branches, number of fruits per branch, length and diameter of fruits, absolute growth rate, yield per plant, number of fruits per plant, and fruit weight. We used descriptive statistics; for quantitative and qualitative characteristics, we used regression analysis and means test, through Tukey´s test at 5% probability. FENOLOGIA E PRODUÇÃO DA FIGUEIRA CV. ROXO DE VALINHOS NO OESTE POTIGUARRESUMO -A figueira 'Roxo de Valinhos' é uma das variedades mais cultivadas no mundo, no entanto, ainda existem poucos estudos sobre a fenologia e produção de figueiras, especialmente em regiões semi-áridas. Este estudo avaliou os aspectos fenológicos e produtivos da cultivar de figueira 'Roxo de Valinhos' no Oeste Potiguar. O experimento foi realizado de julho a dezembro de 2015 no pomar didático da Universidade Federal Rural do Semi-Árido, UFERSA. Os seguintes aspectos fenológicos foram analisados: poda do início ao brotamento, emergência e maturação do primeiro fruto, início da colheita, comprimento e diâmetro dos ramos, número de frutos por ramo, comprimento e diâmetro dos frutos, taxa de crescimento absoluto, rendimento por planta, número de frutos por planta e peso do fruto. Utilizamos estatística descritiva; Para as características quantitativas e qualitativas, utilizou-se análise de regressão e teste de médias, através do teste de Tukey a 5% de probabilidade. As figueiras mostraram boa adaptabilidade às regiões semi-áridas e precocidade quando comparadas às figueiras das regiões temperadas, em todos os estádios fenológicos; A cultivar estudada apresentou resultados promissores para o cultivo nesta região.

Despite the many advantages of pineapple plants offered by micropropagation, there is difficulty in rooting and slowness in the growth of seedlings, requiring a long period of acclimatization in the greenhouses. The aim of this study was to evaluate organic sources and water retention polymers used for pineapple cultivar seedlings during the acclimatization phase. The experimental design was randomized blocks in a 2 × 2 × 3 factorial design. Bovine and goat manures were the organic sources that provided the greatest increases in growth characteristics for both cultivars. Goat manure was the organic sources that provided the greatest increases in growth characteristics for both cultivars. Provid seedlings with 20 leaves, height of 19.4 cm, diameter of the rosette of 26.03 mm and 23.1 cm of length of the root system at 270 days to "Vitória". For "Imperial" the goat manure promoted seedlings with 20 leaves and height of 27.8 cm in 220 days. Bovine manure provided greater nutritional gains to seedlings. The use of the hydrogel did not favor the growth of shoots. However, it resulted to the increase in root dry mass when incorporated into the manure for both cultivars. The "Imperial" cultivar had a higher macronutrient intake on seedlings' leaves than the "Vitória" cultivar at 270 days of acclimatization.

Armazenamento e qualidade pós-colheita de frutos de figueira cv. Roxo de Valinhos no Oeste Potiguar Storage and quality of fig tree cv. Purple of Valinhos fruit post-harvest in West Rio Grande do Norte RESUMO: Os frutos de figueira apresentam uma vida útil relativamente curta, em virtude de sua frágil estrutura e seu elevado metabolismo, o que exige enormes cuidados em seu armazenamento. Objetivou-se com este trabalho avaliar os atributos físico-químicos nos diferentes tempos de armazenamento na conservação pós-colheita de figueira cv. Roxo de Valinhos. Utilizou-se delineamento experimental inteiramente casualizado, em esquema fatorial 5 x 3 (5 tempos de armazenamento: 0, 4, 8, 12, 16 dias; e 3 pontos de colheita: 50, 75 e 100% maduros), com quatro repetições e 8 frutos por tratamento. Os figos foram armazenados em câmara fria, em temperatura de 10 ± 2°C e 80-90% de umidade relativa. Estes fatores se mostraram como uma eficiente alternativa para manter a qualidade dos frutos por até 4 dias para as características de massa fresca e vitamina C, enquanto o teor de sólidos solúveis (°Brix) teve seus melhores valores aos 16 dias de armazenamento. O estádio de maturação III obteve maior comprimento e diâmetro, bem como menor perda de massa fresca e firmeza dos frutos.

Aims: Fig plants produce fruits in branches of the year, which grow after emission of buds from the leaf armpits. And the lopping system is one of the most common practices among the green fig farmers to increase production. Thus, the present work aimed to improve the physical, chemical and productive characteristics of fig trees in the semiarid region of Brazil. Study Design: A complete randomized block design was used in a 3x2 factorial scheme (three pruning intensities: 5, 10 and 15 cm in length; and two lopping systems: with and without lopping), constituting six treatments with four replicates. Each experimental plot consisted of five plants, but only the three central plants were used. Place and Duration of Study: The experiment was conducted in the didactic orchard of the Federal Rural University of Semiarid (UFERSA), Mossoró, RN. Methodology: The treatments were: 5 cm pruning without lopping; 5 cm pruning with lopping; 10 cm pruning without lopping; 10 cm pruning with lopping; 15 cm pruning without lopping; 15 cm pruning with lopping. The following variables were analyzed: fruit weight (g), fruit length (cm), fruit diameter (cm), pulp firmness (N), soluble solids content (ºBrix), titratable acidity (%), vitamin C content (mg ascorbic acid 100 g-1 pulp), fruit yield (number of fruits plant-1 and kg plant-1). Data were submitted to analysis of variance by the F test at 5% probability and means were grouped using the Tukey test at 5% probability. The analysis was performed using R software version 3.5.2. Conclusion: Pruning intensity 10 cm in length and the use of lopping system influenced the physical, chemical and productive characteristics of fig plants in the Brazilian semiarid region.

Fig production and quality are associated with the number of branches per plant and may vary among regions according to the climatic conditions and crop management. In this work, we studied the influence of the number of branches per plant on the production and fruit quality of 'Roxo de Valinhos' figs under semiarid conditions. The experiment was carried out at the didactic orchard of Federal Rural University of Semiarid (UFERSA), Mossoró city, Rio Grande do Norte state, Brazil. Fig plants were grown with 6, 12, 18, or 30 branches in a completely randomized block design with four replicates and four plants per plot. Plants without thinning were also cultivated as controls. The number of fruits per plant, productivity, fruit length, fruit diameter, and fruit weight were evaluated. Additionally, fruit firmness, titratable acidity (TA), soluble solids content (SS), maturation index (SSC/TA), and vitamin C content were analyzed. The results showed that plants cultivated with 12, 18, and 24 branches produced fruits with higher weight, more fruits per branch, and more fruits per plant and thus were more productive. Additionally, fruits showed a high vitamin C content and maturation index
