1. Essential oils in the control of Colletotrichum gloeosporioides f. Sp. cepae in onion seeds
RESUMO A antracnose causada pelo fungo Colletotrichum gloeosporioides f. sp. cepae é umas das principais doenças na cultura da cebola. A principal estratégia de controle deste fungo é o controle químico com fungicida sendo esta técnica utilizada na maior parte dos cultivos. Atualmente vem sendo estudados métodos de controle de doenças que sejam menos

2. Nitrous Oxide Emissions in No-Tillage Onion ( Allium cepa L.) Crops Are Increased by Oilseed Radish Cover Crop and Poultry Manure Application
ABSTRACT The use of cover crops and poultry manure (PM) is an alternative to reduce the use of synthetic inputs and can contribute to the nutrient cycling in onions ( Allium cepa L.) grown under a no-tillage system. However, this management practice may contribute to an increase in N2O emissions to the atmosphere. The aims of this study were to evaluate the

3. Chemical Properties in Macroaggregates of a Humic Dystrudept Cultivated with Onion under No-Till and Conventional Tillage Systems
ABSTRACT Nutrients present in soil aggregates are essential for maintaining the productive capacity of agroecosystems and environmental quality. The aim of this study was to evaluate the chemical properties of macroaggregates of a Humic Dystrudept cultivated with onions under a no-till vegetable system (NTVS) compared to the conventional tillage system (CTS)

4. Release of Phosphorus Forms from Cover Crop Residues in Agroecological No-Till Onion Production
ABSTRACT Cover crops grown alone or in association can take up different amounts of phosphorus (P) from the soil and accumulate it in different P-forms in plant tissue. Cover crop residues with a higher content of readily decomposed forms may release P more quickly for the next onion crop. The aim of this study was to evaluate the release of P forms from res

5. 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

6. Influence of Fusarium spp. isolate and inoculum density on resistance screening tests in onion
Fusarium basal rot (FBR), which is caused predominantly by Fusarium oxysporum and F. proliferatum, is the main limiting factor of onion crops. Resistant cultivars obtained in other countries do not behave as such in Argentina crop fields. The cultivars Antártica-INTA, Grano de Oro-Seminis, Valcatorce-INTA and TW-2007 (reported as tolerant) were tested with

7. As relações sociais de produção e a produção do espaço agrário em São José do Norte
O objetivo deste trabalho é o de analisar as causas que impossibilitam o avanço da agricultura de racionalidade capitalista, representado pelo cultivo do arroz, sobre o sistema de produção não tipicamente capitalista, representado pelo cultivo de cebolas. Por esta razão, estudam-se as causas do isolamento do município de São José do Norte ¿ Brasil.
