1. Occurrence of leaf blast on white oats, Italian ryegrass and wheat in Southern Brazil
RESUMO A bacteriose da nogueira é causada por Xanthomonas arboricola pv. juglandis. Em Zavalla (Santa Fe), o cultivo da nogueira concentra-se na produção de plantas enxertadas em viveiro. O objetivo deste trabalho foi quantificar o efeito do ambiente no desenvolvimento epidêmico da bacteriose da nogueira em variedades susceptíveis e de melhor comportame

2. Validation of white oat yield estimation models using vegetation indices
ABSTRACT The use of remote sensing in agriculture presents some practical applications in crop production forecast. In this context, studies with remote sensing are scarce for crops such as white oats, which may indicate the capacity of using this technique in the crop. The aim of this study was to evaluate the accuracy in validation of white oat biomass and

3. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

4. Biomass and nitrogen accumulation in white oat (Avena sativa L.) under water deficit
ABSTRACT Knowledge on nitrogen absorption rate by crops can indicate important managements, especially the definition of rates of this nutrient and the best time for topdressing application. This study aimed to evaluate and compare the accumulation of biomass and nitrogen in white oat cultivated under severe, moderate and no water deficit. Treatments consist

5. Agronomic performance of white oats cultivated under fertigation with treated sewage effluent and definition of critical limits of Normalized Difference Vegetation Index
ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.

7. Prediction of pressure drop through packed beds of granular materials: influence of moisture reduction and air velocity
Resumo Neste estudo foi investigada a influência da umidade do sólido sobre a queda de pressão em leitos fixos de soja, cevada, lentilha e aveia. As propriedades dos grãos e do leito foram determinadas variando-se a umidade dos sólidos entre o valor de equilíbrio até 0,24 g g-1 (massa de água por massa de sólido seco). As quedas de pressão nos leit

8. Soil conservation management with cover crops: effects on critical energy levels, release and dispersion of aggregates
ABSTRACT The normalized dispersion index (NDI) and the b/a index are commonly used to express the stability of aggregates measured by ultrasound. However, few studies have used the critical energy (CE) extracted from modeling to explain the effects of soil use and management on soil aggregation. The objective of this study was to evaluate the influence of so

9. Emissions of Nitrous Oxide and Methane in a Subtropical Ferralsol Subjected to Nitrogen Fertilization and Sheep Grazing in Integrated Crop-Livestock System
ABSTRACT Brazilian agriculture contributes significantly to nitrous oxide (N2O) and methane (CH4) emissions, so the understanding of such emissions at the field is crucial for mitigation strategies. This study quantified the impact of N application and sheep grazing on the N2O and CH4 emissions from a subtropical Ferralsol under an integrated crop-livestock

10. Soil compaction in areas of maize used for silage with the application of wastewater
RESUMO Durante dois anos consecutivos, a resistência mecânica do solo à penetração (RP) foi avaliada em áreas de produção de milho segunda safra para silagem. A retirada da parte aérea do milho no processo de silagem deixa o solo exposto, sujeito à compactação, o que pode comprometer o sistema plantio direto (SPD). Neste contexto, este trabalho t

11. Winter Species Promote Phytoremediation of Soil Contaminated with Protox-Inhibiting Herbicides
RESUMO: A fitorremediação compreende uma das principais formas de descontaminação de substâncias orgânicas e inorgânicas no solo, economicamente viável e de baixo impacto ambiental. Objetivou-se com este trabalho verificar a eficiência de espécies vegetais de inverno na fitorremediação de solo contaminado com fomesafen e sulfentrazone, utilizando

12. Production of Fodder in a Treeless System and in Silvopastoral System in Central Argentina
ABSTRACT This paper aims to identify the spatial and temporal distribution of net aerial primary production (NAPP) of oats and sorghum in silvopastoral systems (SPS) and in a treeless situation (TLS), in Southern Cordoba, Argentina. The silvopastoral systems are composed of three woody cultures (Pinus elliottii, Eucalyptus viminalis and Quercus robur), and
