13. AERIAL AND GROUND APPLICATION OF FUNGICIDE IN CORN SECOND CROP ON DISEASES CONTROL
ABSTRACT The aim was to evaluate the diseases severity on corn second crop. The research was conducted on the agricultural year of 2013 and 2014, evaluating the application quality over the fungicide spraying. The hybrid used was PIONEER 30k75 BT HERCULEX, evaluating the diseases severity previously and after the fungicide spraying, spray deposition on the c

14. Cover Crops Effects on Soil Chemical Properties and Onion Yield
ABSTRACT Cover crops contribute to nutrient cycling and may improve soil chemical properties and, consequently, increase crop yield. The aim of this study was to evaluate cover crop residue decomposition and nutrient release, and the effects of these plants on soil chemical properties and on onion (Allium cepa L.) yield in a no-tillage system. The experiment

15. Water erosion in surface soil conditions: runoff velocity, concentration and D50 index of sediments in runoff
ABSTRACT Water erosion and contamination of water resources are influenced by concentration and diameter of sediments in runoff. This study aimed to quantify runoff velocity and concentration and the D50 index of sediments in runoff under different soil surface managements, in the following treatments: i) cropped systems: no-tilled soil covered by ryegrass (

16. Water Erosion on an Oxisol under Integrated Crop-Forest Systems in a Transitional Area between the Amazon and Cerrado Biomes
ABSTRACT Water erosion is one of the main factors driving soil degradation, which has large economic and environmental impacts. Agricultural production systems that are able to provide soil and water conservation are of crucial importance in achieving more sustainable use of natural resources, such as soil and water. The aim of this study was to evaluate soi

17. Energy balance and evapotranspiration of melon grown with plastic mulch in the Brazilian semiarid region
Melon plants (Cucumis melo L.) are grown in the state of Rio Grande do Norte (RN), the largest producer of melons in Brazil, with plastic mulch and agrotextiles. Studies of crop evapotranspiration (ET) under these conditions are required to ensure adequate irrigation. This study aimed to determine the crop coefficients (Kc) of irrigated melon plants grown wi

18. BRS Centauro - oat cultivar for ground cover and grazing
Plants and seeds of oat cultivar BRS Centauro, of the species Avena brevis Roth., are highly uniform. The crop cycle is long, the suitability as fodder excellent, and leaf production particularly high, resulting in better quality forage than that of the black oat forage controls.

19. Desempenho de cultivares de mirtileiros dos grupos rabbiteye e highbush em função da cobertura de solo
A cultura do mirtileiro está em expansäo no Brasil principalmente por seus efeitos benéficos à saúde. Devido ao fato de seu cultivo ser recente no País, a cultura ainda carece de estudos relacionados ao manejo, dentre os quais a adequada cobertura do solo. Nesse sentido, o objetivo deste trabalho foi avaliar o desenvolvimento vegetativo e produtivo de

20. Does crotalaria (Crotalaria breviflora) or pumpkin (Cucurbita moschata) inter-row cultivation in restoration plantings control invasive grasses?
Alternative methods to control invasive fodder grasses are necessary to reduce the use of herbicides in forest restoration, which has been carried out primarily in riparian zones. We sought to investigate if inter-row cultivation of crotalaria (Crotalaria breviflora DC) or pumpkin (Cucurbita moschata Duschene ex. Poir) with native tree species is an efficien

21. Estudo morfológico e hidroquímico de pequenas depressões na Nhecolândia, Pantanal, MS / Morphological and hydrochemical study of small depressions in Nhecolândia, Pantanal, MS
The southern part of the Taquari alluvial fan, called Nhecolândia, is a sub-region of the Pantanal of Mato-Grosso exhibiting a complex of round shape lakes, draining fields, forested sandy areas, small watercourses and small depressions. Former studies have shown that the sub-superficial water fluxes depend on the intensity of the flood and on the presence

22. Efeitos do uso e cobertura do solo sobre o conforto higrotérmico / Effects of the use and soil cover on the hygrothermal comfort
Given the importance of obtaining an urban design based on the microclimate and the possibility of the use of trees as a factor in mitigation of urban distress, this study evaluated the effect caused by three different spatial arrangements of urban forests and the use and occupation on soil in temperature and humidity of the environment in surroundings area.

23. Modelo dos processos de negócio para gerenciar a remanufatura / Business processes model for remanufacturing management
Remanufacture is an industrial process in which worn-out products are restored to as new condition. Although its growing attention by academy and industry, related research topics are still addressed in a fragmented way and it is difficult to embody them to companies activities. In this sense, business processes approaches can be used to analyse and integrat

24. Densidade de semeadura e consÃrcio de braquiÃria e estilosantes visando à formaÃÃo de cobertura vegetal para a cultura da soja / Seeding density and consortium of brachiaria and stylosanthes aiming at vegetation cover to the soybean crop
The tillage efficiency is directly related to the management and choice of vegetation species prior to sowing the crop. In this context, this study examined the effect of brachiaria sowing densities (Brachiaria ruziziensis) (10; 15 and 20 kg ha-1), stylosanthes (Stylosanthes macrocephala and Stylosanthes capitata) (3; 4.5 e 6 kg ha-1) and consortium of these
