Tipos de adubação para a videira 'BRS - violeta' cultivada em latossolo vermelho no sudoeste do Paraná

The vineyard culture, in the Southwest of Paraná, has faced an evolution in recently years. However, some technical barriers has contained the expression of its full potential. Among which, the lack of scientific and technical support about the fertilization management and the fertility maintenance of production fields, is the most worrying. This fact, allied with the raising on the consumers demand for ecological correct products, are the motivations for the present study, whose main objective was to evaluate the effects of different fertilizer formulations, based on alternative nutrient sources, on grapevine yield and grape fruit quality, aiming at the improvement of those parameters and the maintenance of soil fertility. To achieve this goal, an experiment has been evaluated since 2008, at the experimental area of the Federal Technological University of Paraná, Campus Pato Branco, where ten treatments were being tested, combining or isolating shale derivates from other alternative nutrient sources. Those are the treatments: T1: Gafsa Rock Phosphate (GRP) + K2SO4; T2: GRP + RPB (Rock Powder Bioland®); T3: GRP + K2SO4 + LH (Laying Hen Litter); T4: GRP+ RPB + LH; T5: GRP + K2SO4 + MBR (Matrix Shale 3); T6: GRP + RPB + MBR; T7: GRP + K2SO4 + MBR + LH; T8: GRP + RPB + LH + MBR; T9: TSP (Triple Superphosphate) + Urea + KCl and T10: absolute control. The usage of fertilization, specially the alternative fertilization, improved soil fertility characteristics and also the yield on the last two evaluated harvests. The potassium sulfate improved the potassium availability on soil, while improved yield on the last three harvests. The MBR improved the phosphorus availability, improved post-harvest conservation and improved the yield on the last evaluated harvest.

A inserção da educação ambiental não formal no processo de implantação de saneamento ambiental na comunidade rural Colonia Mergulhão, São José dos Pinhais - PR

One of the biggest environmental problems of the population is the lack of sewage treatment, especially in rural communities and low-income. The development of technologies for efficient, low-cost sanitation need to be developed to meet the disadvantaged people of this basic service. This work was the implementation proposal of a technology called constructed wetlands, also known as Wastewater Treatment Plant for Roots Zone - ETEZR. The objective was to develop a non- formal environmental education proposal for redevelopment, using outreach methods for residents and deployment of this technology ETEZR in the rural community of Cologne Grebe in Sao Jose dos Pinhais - PR. With technical support from the Paranaense Technical Assistance and Rural Extension Institute -EMATER and the Federal Technological University of Paraná - UTFPR, 5 ETEZR were deployed in the colony through three theoretical and practical workshops, which involved total 67 people from the community 5 technicians EMATER and 13 of the Municipal Town Hall. Após4 months of implementation were carried out two collections of raw wastewater and treated to analyze physical, chemical and biological parameters. The results evaluated by chemical parameters BOD, COD, phosphorus, ammonia nitrogen comparing raw and treated sewage, demonstrate that ETEZR are effective in the treatment of sewage. 5 Seasons minimum and maximum efficiency between the basic parameters analyzed were 52.2 to 95.5% for BOD; 47 to 94.5% for COD; 21.5 to 96% phosphorus; 30-98% for ammonia nitrogen. Oils and greases, and a series of solid also achieved a significant reduction in their values when comparing the raw sewage and treated sewage, and biological parameters evaluated by means of coliforms showed a reduction of 80 to 99%. With the implementation of environmental education process aimed sanitation was possible to evaluate the perception of the population to accept the environmental sanitation technology using the ETEZR, understand the needs and sanitation concepts for the community. This research evaluated the development of the methodology applied by the non-formal environmental education in order to provide subsidies for rural sanitation plan process for the municipality.
