15. Eficiência de roçadas no controle de Bidens pilosa e Commelina benghalensis em competição com a cultura do milho / Efficiency of clearings on the control of Bidens pilosa and Commelina benghalensis in competition with corn crop
Dentre os fatores que dificultam a expansão da área cultivada com milho orgânico destaca-se o controle das plantas daninhas. Neste sistema de cultivo são permitidos apenas os métodos de controle culturais e mecânicos, que na maioria das vezes são pouco eficientes e não adequados ao sistema de plantio direto. Neste trabalho avaliou-se a eficiência da

17. Padrões climáticos atuais e futuros de temperatura do ar na Região Sul do Brasil e seus impactos nos cultivos de pêssego e de nectarina em Santa Catarina / Current and future air temperature climatic patterns in the South Region of Brazil: the impacts on peach and nectarine production in Santa Catarina
Over the years, climate changes and their direct impacts were observed in different parts of the globe. The present study considers the main air temperature patterns, including their extreme values, in Southern Brazil and assesses their impacts on peach and nectarine production. The analysis is based on daily air temperatures recorded at weather stations dis

18. Eficiência agronômica de um fertilizante fonte de micronutrientes nas culturas da soja e milho / Eficiência agronômica de um fertilizante fonte de micronutrientes nas culturas da soja e milho / Agronomic efficiency of fertilizer fount of micronutrients in soy and corn cultures / Agronomic efficiency of fertilizer fount of micronutrients in soy and corn cultures
The present work aimed to value the agronomic efficiency of different doses of a fertilizer fount of micronutrients applied through the soil in soy culture and the residual answer in culture rotation with the corn, by the determination of chemical attributes related with the productivity. The study was performed in fields condition in a Distrofic Red Latosoi

20. Caracterização da contaminação fúngica e por micotoxinas em diferentes fases da cultura do amendoim (Arachis hypogaea L.) produzido no Rio Grande do Sul, Brasil / Characterization of fungi and mycotoxins at different stages of peanut culture (Arachis hypogaea L.) produced in Rio Grande do Sul, Brazil
Mycotoxins are secondary metabolites produce by filamentous fungi that can contaminate grains in different stages of pre and postharvest management. The objective of this study was to investigate the occurrence of fungi and mycotoxins at different maturation stages of peanut produced in different regions of south of Brazil during 2006/2007 and 2007/2008 harv

21. Sewage sludge application in cane-plant as nitrogen and phosphorus source and its environmental effects / Aplicação de lodo de esgoto em cana-planta como fonte de nitrogênio e fósforo e seu impacto ambiental
The potential agricultural use of the sewage sludge is due to their organic matter and nutrients contents, mainly nitrogen and phosphorus, the most important constituint. However, there is a lack of research to adequate the nitrogen and phosphate fertilizer doses to be applied in agricultural fields treated with this residue. Despite the evident benefits of

22. The process of natural regeneration and ecosystem restoration in former forest production areas / O processo de regeneração natural e a restauração de ecossistemas em antigas áreas de produção florestal
In Forest Companies that cultivate fast-growing forest species for industrial supply, it has been usual the existence of commercial production areas that need to be converted in protected areas with native vegetation. Nevertheless, depending on local conditions and landscape context, the natural regeneration process is not enough to guarantee the successiona

23. Manejo da irrigação do feijoeiro cultivado em plantio direto no sistema integração lavoura-pecuária / Irrigation management of no-tillage common bean crop in farming-livestock system
The water is becoming a resource more and more scarce, with growing strategic importance in the sections environmental, economical, social and political. The irrigated agriculture is responsible for considerable portion of the agricultural production, however, it is the activity that more it demands water. In the irrigated areas, one of the most important fa

24. Comportamento do fósforo frente à adubação fosfatada em latossolos com diferentes históricos de uso / Behavior of phosphorus in phosphated fertilization in Oxisols with different use histories / Comportamento do fósforo frente à adubação fosfatada em latossolos com diferentes históricos de uso / Behavior of phosphorus in phosphated fertilization in Oxisols with different use histories
O fornecimento de fósforo representa parte expressiva do custo de produção das culturas. No sistema de plantio direto (SPD) existe uma tendência de melhor aproveitamento do P, sobretudo em áreas que já vem sendo cultivadas há mais tempo. Porém, há a necessidade de definição/confirmação da melhor utilização de fertilizantes fosfatados sob SPD.
