Item Avaliação da biomassa de plantas de cebola cv. 1205 e cv. Serengeti em solos conducentes à nematose tratados com produtos biológicos(2019) Soares, Maurício Meira; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/3614090907577987The onion Allium cepa highlights-like vegetable important socioeconomic for the country, the predominance of culture medium, small producers and the family nature, generating about 250 thousand direct jobs in production. How the culture has its phytopatological problems, the decision has been made for the economics made from the production of the largest production in production. In order to control the problems, the tests are being studied and the biological control of the main focus is the use of nematological bacteria and fungi that promote the protection of the roots of the growth, besides promoting an increase in the biomass of the plants. The use of the microorganisms may have had an important relation with the potential of soil management, cleaning of the ecosystem of systems and the suppressive. The objective of this study was to evaluate the biomass of hybrid 1205 and Serengeti crop plants grown on soils with three biological products. Three bioproducts will be tested: product 1 containing bacteria: Bacillus pumilus 1.0x10¹¹ (endospores / L), Bacillus subtilis1.0x10¹¹ (endospores / L) and Bacillus amyloliquefaciens 1.0x10¹¹ (endospores / L), Product 2 have the bacteria Azospirillum sp. 1.0x109 (UFC / dose), Pseudomonas sp. 1.0x109 (CFU / dose), Rhizobium sp. 1.0x109 (CFU / dose) and the fungus Saccharomyces sp. 1.0x109 (CFU / dose) and product 3 is a base of Bacillus subtilis1.0x10¹¹ (CFU / g) and Bacillus licheniformis 1.0x10¹¹ (CFU / g). After 60 days, morphological variables were identified as buyer of aerial and root parts, diameter of pseudocaule and bulb, weight of fresh matter and dry material and finally determined the index of galls formed not root system. The results obtained showed that the biomass concentrations between the plants cultivated in soils and with the bioproducts were concluded in comparison with the biomass among the hybrid cultivars of onion cv. 1205 and cv. Serengeti.Item Avaliação da biomassa de plantas de goiabeira cv. paluma tratadas com produtos biológicos em solos conducentes à Meloidogyne spp(2019) Souza, Daniel Ericles dos Anjos; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/5706869625614564; http://lattes.cnpq.br/1272248073820183The cultivation of guava (Psidium guajavaL.) is widespread throughout the world, [being a kind of reality with high economic and market potential, which, with this, still presents great possibilities of expansion around the world.]In Brazil, São Paulo and Pernambuco lead production, accounting for 36.3% and 31%, accounting for 67.3% of national production. However,diseases in guavain Brazil directly influence the productivityof this culture. Among the diseases, meloidoginose is one of the main causes of damage to guava producers. In this context, the work was evaluated as the aerial biomass problem and root portion of guava seedlings of cv. Paloma for two soil conditions leading to the three biological products. Soils were grown in areas of guiding guava in nematodes under two management, soil 1 with remnant characteristics and soil 2 in full culture, deposited in 10 L volume vessels that are projected with three products formulated with Bacilluspumilus, B. subtilis, B. amyloliquefaciens, Azospirillum sp., Pseudomonas sp., Rhizobium sp., Saccharomyces sp., B. licheniformis. With the end of the 90 days, with the measurement of the first planes, the fresh mass and the dry and dry mass, the diameter of the stem, pair of leaves, number of leaves and number of branches. The experiment was carried out without a randomized complete block design (DBC) with eighttreatments and four replications where the treatments, arranged in a factorial scheme 4 x 2. The results were those biological products tested in this experiment, not having as parameter the biomass differences in question relation to the two types of cultivated soils.Item Qualidade sanitária de sementes de capim buffel (Cenchrus ciliaris l.) comercializadas nos municípios de Afogados da Ingazeira, Flores e Calumbi no Sertão do Pajeú(2022-05-23) Araujo, Rafael Pereira de; Albuquerque, Neilza Reis Castro de; http://lattes.cnpq.br/5706869625614564; Não localizadoThe seed is the main disseminator of diseases and the lack of knowledge of the sanitary state of the lot can bring several losses in the establishment of the crop. For buffel grass there is a scarcity of works that inform the sanitary quality of plots sold in Sertão do Pajeú. Thus, the objective was to evaluate the phytosanitary quality of Cenchrus ciliaris seeds commercialized in Sertão do Pajeú. The grass buffel seeds were acquired from the trade and directly from the producer in three municipalities in the region. The batches of seeds sold at home farming were acquired from the municipalities of Afogados da Ingazeira and Flores, harvested in the 2021 crop, the seeds purchased directly with the product came from the municipality of Calumbi, harvested in the 2022 crop, from each municipality it was obtained a batch containing 1 kg of seed, followed by a sanity and germination test. To evaluate the health of the seeds, the filter paper method was used. A total of 200 seeds were used from each randomly chosen lot and arranged in a completely randomized design. Prior to the test, the seeds were disinfected in sodium hypochlorite solution (1.5%) for 2 minutes and 30 seconds in 70% alcohol, the 200 seeds were divided into 10 petri dishes containing a sterile and moistened filter paper (20 seeds / board). The seeds were incubated for eight days at room temperature and under alternating light (12h light/12h dark). At eight days of incubation, they were analyzed for fungal incidence through visual analysis and plating, germination with counting the number of germinable seedlings. The data obtained on fungal incidence and germination were transformed into √(x+0.01), the means of the lots were statistically compared by the Scott-Knott test at 5% probability by the SISVAR program. It was observed that the seeds sold in the municipalities of Afogados da Ingazeira and Flores presented fungal contaminants. The batch from Calubim did not show the presence of contaminants, the presence of bacteria was also observed in the test performed. In the batch of seeds of Afogados da Ingazeira the genera Fusarium, Penicillium, Mucor and Trichoderma were detected in high incidence, for the batch from the municipality of Flores the genera Penicillium and Alternaria were detected in high incidence. The fungal incidence was higher in the batch of Afogados da Ingazeira with 50% of the seeds contaminated. Regarding germination, there was no significant difference at 0.5% probability by the ScottKnott test for three cities studied.
