Lettuce (Lactuca sativa L.) belong to Asteraceae (Compositae) family and is considered one of the most important vegetable crops in Brazil, despite climatic differences and consumption habits. Lettuce crops is preferably carried out in mild climate, however, it presents a wide adaptation to different climatic conditions, with successive crops possibility in the same year. In Brazil, mini lettuce is a growing and promising market niche, which has attracted interest from some producers, consumers and restaurants. The aim of this study was to evaluate fifteen lettuce cultivars (Barlach, Cousteau, Excite, Klee, Sartre, Triplex, Xandra, Bruma, Escarcha, Jonction, Kiribati, Mondai, Rosaine, Rouxai and Tudela), in spring season, in Recife municipality, PE, Brazil, to determine whether cultivars are suitable for crop large-scale production in one of the warmer season of region. The experiment was carried out in the months of September to November using a randomized complete block design with 15 cultivars and five replicates. The characteristics germination percentage, number of leaves, diameter and height plant (cm), commercial fresh mass (g) and early elongation of floral stem susceptibility were evaluated. The germination of cultivars evaluated didn’t present significant difference at 5% probability level of tukey test. The data indicate that lettuce cultivars of Rosaine (cos), Kiribati (oak leaf), Jonction and Triplex (crisp), Sartre (butter head), and Escarcha and Bruma (iceberg) were the highest productivity in their respective commercial groups. None of the cultivars evaluated present elongation of floral stem lettuce precocious.

The melon crop (Cucumis melo L.) belongs to the Cucurbitaceae family, being considered a tropical fruit of high commercial value, appreciated for its peculiar characteristics and great popularity in the world; currently, is one of the freshest fruits most exported by Brazil. Due to new large areas cultivated with melon, often without adequate technical guidance, the occurrence of problems in cultivation has increased, causing major problems for the crop, as diseases, nematodes and soil salinization, sometimes limiting cultivation. These problems generated the need to search for alternatives to melon cultivation. One of the alternatives found was the use of grafting, by the use of tolerant or pathogen resistant rootstocks and adverse environmental conditions. Studies on the behavior, compatibility, productivity, resistance and / or tolerance of rootstocks and grafts, as well as evaluations of rootstock species under different environmental conditions are fundamental for the choice of suitable rootstock, combining resistance and productivity. Therefore, the objective of this work is to evaluate four genotypes of Cucurbitaceae family (Aodai, Verde Comprido, Xingó Jacarezinho and Maranhão) that can be used as grafted rootstocks. The experiment was conducted in the city of Recife / PE, from September to October 2018, using a completely randomized design. The genotype that provided the higher survival rate was the Aodai cucumber, which presented about 85% of survival. The genotype Verde Comprido cucumber presented 72% of glue. The pumpkin genotypes Xingó Jacarezinho and Maranhão presented values of 60% and 53%, respectively, with the Maranhão genotype presenting the lowest percentage survival value.

The culture of the okra (Abelmoschus esculentus L.) is an annual fruit, shrub, erect and stem semilenhoso, originating from the region of Ethiopia, in the horn of Africa. In Brazil, there are excellent climatic conditions for its cultivation, especially in the Northeast and Southeast regions, where it is a popular culture, mainly by small and medium producers, the objective of this work was to evaluate the behavior of the okra handled under different types of pruning training, and under different types of soil cover. The work was carried out in the didactic garden of the Department of Agronomy of the Federal Rural University of Pernambuco, from April 2018 to August 2018. The design was a randomized complete block design in the factorial scheme (3 x 4), with 4 replications. (plastic film, uncoated and mulch) and four types of driving pruning (plastic film, without cover and mulch), and the type of pruning (apical pruning, lateral pruning up to 20 cm, pruning lateral to 40 cm and without pruning). The number of fruits per plant, fruit yield, mean length (cm), mean diameter (cm) and mean fruit mass (g) were evaluated. The treatment of lateral pruning up to 40 cm over plastic covering effect was the one that presented the highest number of fruits per plant, resulting in the treatment that provided higher final yield. The mean length, mean diameter and mean weight of fruits did not differ between treatments, as these parameters are intrinsically related to the way the harvest is made, and the age of the fruit when harvested.
