Fertilidade do solo, composição mineral e produção do quiabeiro sob lâminas de ...
Bertino, Antonio Michael PereiraThe okra is a vegetable that has been gaining expression in the Northeast region, but the information on irrigation management and organic fertilization is still infrequent in the literature, therefore, research in this sense must be developed. In this direction an experiment was developed to evaluate the productive performance of the okra and the chemical attributes of the soil as a function of irrigation slid...
Variabilidade espacial da resistência à penetração em solo cultivado com cana-d...
Silva, Josévaldo RibeiroThe cultivation of sugarcane (Saccharum oficcinarum L.) is one of the main activities of the primary sector in the northeast of Brazil. This crop always received high advances in technology, thus the harvesting way changed, being realized in the mechanized way. Despite the benefits of the mechanized harvesting, an intense trafficability of the sugarcane harvesters, can cause compaction by eminently changing the...
Variabilidade espacial da resistência a penetração em solo sob diferentes condi...
Souza, Maíra da CunhaAn inherent characteristic of soils is its heterogeneity; however, plantings, especially the mechanized ones such as perfomed in the sugarcane crop, tend to cause changes that increase even more the variability in the physical attributes of the soil. Based on that, the objective of this study was to evaluate the spatial variability of the resistance to penetration in soil under sugarcane cultivation in the micr...
Estados alternativos de equilíbrio em dois lagos rasos da bacia hidrográfica do...
Alves, Rafael Machado de AraújoThe shallow lakes are susceptible to multiple impacts ecosystems, including eutrophication, often artificial, linked to population and industrial growth disorderly. The work has as i) objectives to characterize the relationship of land use and land cover with the clear waters of states and turbid in two lakes in Mamanguape Basin and ii) evaluate the effects (direct and indirect) of the abiotic variables on perc...
Decomposição e mineralização de nutrientes de fitomassa recalcitrante em função...
Lima, Lúcia de OliveiraFor green manure meets the demand for nutrients, the consortium culture, there is the need for the decomposition and release of nutrients from plant residues added to the soil occur in synchronism with the nutrient absorption curve of commercial interest culture. The objective of this study was to evaluate the chemical characteristics of difficult to decompose materials and study the effect of N and P, and the ...
Crescimento, teores foliares e taxa relativa de absorção de N, P e K em Moringa...
Souza, Francisco Marto deThe objective of this study was to evaluate the growth, mass production, foliar contents and relative absorption rate of N, P and K in Moringa oleifera Lam. Fertilized with four doses of chicken bed (0.0, 40.0, 80.0 and 120.0 g dm-3) and two particle sizes (1 and 4 mm). The experiment was conducted in a randomized complete block design with four replicates. The experimental unit consisted of four seedlings, pro...
Óleos essenciais no manejo da mancha marrom de alternaria em tangerineira "DANCY"
Porcino, Mirelly MiguelBrazil is considered the fifth highest producer of tangerines in the world. However, its production has been decreasing due to the attack of diseases, especially the brown spot of alternaria, which has as its causal agent the Alternaria alternata (Fr: Fr) Keissler f. sp. Citri that causes serious economic problems in the culture. In the management of, alternative products are used as the essential oils. This wo...
Qualidade fisiológica e anatomia do tegumento de sementes de Erythrina velutina...
Bezerra, Ana CarolinaErythrina velutina Willd. (Fabaceae), is a native Caatinga species and has its establishment hampered by the occurrence of integument dormancy in the seeds. Thus, as the main form of propagation is sexually, which makes it essential to know the physical, physiological and anatomical aspects of its seeds. The objective of this study was to evaluate the effect of environmental variation in different regions of Pa...
Monitoramento e investigação ecoepidemiológica da contaminação por Staphylococc...
Leon, Candice Maria Cardoso Gomes deThe present study had as objective to monitor the contamination buy Staphylococcus spp. in small-scale milk processing plants in Cariri of Paraiba through a quantitative microbiological analysis and by genotyping of the isolates by REP-PCR method (Repetitive Extragenic Palindromic Sequences). For both, considering the flow chart of processing of pasteurized goat milk in plants, sampling of raw and pasteurized m...
Avaliação das alterações morfométricas e tempo de exposição glandular em cães c...
Brito, Maria Caroline PereiraThird eyelid gland protrusion is a condition of uncertain etiology, common in young dogs. It is believed that inflammation and weakening of the connective tissue that anatomically fixes the lacrimal gland to the periorbital tissues occurs, exposing it and triggering pathological changes in the glandular tissue, which will consequently interfere in the tear film production. The purpose of the study was to correl...
