Production of Cashew Rootstocks Submitted to Organic and Mineral Fertilization

The use of grafted seedlings is a cultural practice that aims at the optimization of agricultural production, and materials of organomineral added to the substrate can help in the well development. The aim of this study was to evaluate the effect of the application of increasing doses of organic and mineral material on the development of cashew rootstocks. The test was conducted in the experimental area of the Federal University of Campina Grande (UFCG), campus Pombal-PB in the period from July to September 2017. The treatments were constituted of five increasing doses of organic matter (0, 100, 200, 300 and 400 g of bovine manure) and four levels of mineral fertilizer (0, 1, 2 and 3 g of NPK). The design was in randomized blocks, distributed in factorial 5 × 4, with 4 replications. For the planting, it was used creole seeds originary of the city of Livramento do Cariri Paraibano and substrate composed by sand texture Franco sandy. At 60 days after sowing, the following variables were analyzed: plant height (cm), leaf diameter (mm), number of leaves, leaf area (cm 2 ), fresh and dry mass, leaf, stem, shoot (g), percentage of biomass (%) and quality index of seedlings. Based on the results obtained, it is concluded that the organic and mineral combination (1 g of NPK and 200 g of bovine manure) provided the greatest increases in vegetative growth characteristics and quality of rootstocks in the cashew tree.

Phenological Characterization and Productivity of the Physalis peruviana L., Cultivated in Greenhouse

The Physalis peruviana L. presents great nutritional value and economic viability, becoming an alternative for the small and medium producer and an innovation for the Brazilian horticulture. However, some information on cultivation, are still scarce. In this context, our objective is to characterizing the phenological phases and productivity of the Physalis peruviana cultivated in a greenhouse in the semiarido paraibano. This work was done in the experimental farm of the Federal University of Campina Grande, campus Pombal, Paraiba. The experiment was driven in a randomized blocks design, with five repetitions, each repetition constituted of five plants. The phenological phases were determined through the height, diameter of the stem, number of leaves, floral buttons, flowers and fruits per plant, production and productivity. The data were submitted to the variance analysis and polynomial regression. The vegetative phase of the Physalis peruviana L. is concluded in a period understood among 32 to 45 days after the transplant (DAT) and the reproductive phase extends until 161 DAT. In the conditions of the semiarid, the crop of the fruits of the Physalis peruviana L. begins to 71 DAT, with a dear productivity of approximately 2 340.95 kg ha-1.

Production of Seedlings of Yellow Passion Fruit Plant in Different Substrates and Saline Levels

In the process of production of seedlings the formulation of substrates that supply the nutritional needs and make available appropriate humidity tenor is relevant for the success and the reduction of costs of the producing with other inputs. In this perspective, it is known that alternative substrates are rich in organic matter, which possesses extenuating action for the harmful effect of the salinity. Therefore, it was aimed at to evaluate the effect of saline waters and formulations of substrates in the production of seedlings of yellow passion fruit plant. Experiment was driven in atmosphere protected in the dependences of the Federal University of Campina Grande, Pombal, Paraiba. The randomized block design was used in factorial outline 5 × 5, being five levels of salinity of the irrigation water (0.3; 1.3; 2.3; 3.3 and 4.3 dS m-1) and five substrates: S1 = soil; S2 = soil, goat manure and bovine manure (1:1:1); S3 = soil and goat manure (3:1); S4 = soil and bovine manure (3:1); S5 = soil, goat manure and bovine manure (3:0.5:0.5). To the 52 days after the sowing the growth analyses and quality of the seedlings were checked. The growth of the passion fruit plant seedlings was inhibited by the salinity in the irrigation water. However, the use of organic inputs in the formulation of the substratum lessens the harmful effect of the saline stress, being the best substratum, soil and bovid manure in the proportion 3:1.

Levantamento etnobotânico da Universidade Federal de Campina Grande, Campus Pombal

A caatinga representa um importante patrimonio brasileiro, destacando-se pela diversidade de especies. Contudo e um bioma que vem sofrendo com a degradacao ocasionada principalmente pelo processo de urbanizacao. A arborizacao, empregando especies nativas e sua identificacao em parques, pracas e ambientes educacionais modificados por esse processo, e vista como alternativa para a diminuicao da degradacao ambiental e a preservacao do bioma. Nessa perspectiva, objetivou-se realizar um levantamento etnobotânico da area urbanizada pela Universidade Federal de Campina Grande, campus Pombal. Para isso, foi realizada a quantificacao das especies, com coletas efetuadas no periodo de dezembro de 2017 a janeiro de 2018. As especies encontradas foram identificadas com auxilio do Herbario Virtual da Flora e dos Fungos – Instituto Nacional de Ciencia e Tecnologia e do Manual de Identificacao de Plantas Arboreas Nativas do Brasil. Registraram-se 567 individuos, distribuidos em 48 especies e 27 familias botânicas. Dentre estas, nim ( Azadirachta indica ), especie exotica, apresentou maior populacao, seguida por jurema ( Mimosa tenuiflora ), nativa da caatinga. A familia que mais se destacou foi Fabaceae, seguida de Meliaceae. Verifica-se que as especies exoticas predominaram sobre as nativas e que ha necessidade do correto planejamento da arborizacao na localidade.
