13. SPATIAL VARIABILITY OF IRRIGATED COMMON BEAN YIELD CORRELATED WITH THE FERTILITY OF A SANDY SOIL
ABSTRACT The common bean is widely cultivated in Brazil. In the 2016–2017 growing season, an experiment was carried out in a Typic Quartzipsamment (or Neossolo Quartzarênico) soil in the municipality of Cassilândia, MS, Brazil, with the aim of characterizing specific aspects of soil management, using a linear and spatial correlation between the irrigated

14. Tillage systems and cover plants change organic fractions of phosphorus in oxisol of eastern Amazonia
ABSTRACT Due to the large extent of degraded areas in the Amazon, the use of conservation systems is very important to contain the advance of the agricultural frontier, and may favor the availability of nutrients such as phosphorus (P). This study evaluated effect of tillage systems on and cover plants distribution of organic P fractions (Po) in oxisol under

15. SIMULATING CROP YIELD, SOIL NITROGEN, AND ORGANIC CARBON IN NO-TILLAGE CROP SEQUENCES IN A SUBTROPICAL CLIMATE IN BRAZIL
ABSTRACT Brazil stands out worldwide for its high grain production in areas of direct sowing. The objective of this study was to simulate and assess the relationship of soil organic carbon content and nitrogen, crop yield, and biomass of two crop sequences under the no-tillage system in a subtropical region of São Paulo, Brazil, using CSM-CROPGRO-Soybean an

16. SOYBEAN AGRONOMIC PERFORMANCE AND SOIL PHYSICAL ATTRIBUTES UNDER TRACTOR TRAFFIC INTENSITIES
ABSTRACT Machinery traffic intensification has been recurrent in intensive agriculture in annual crops, which may lead to structural soil degradation and, consequently, a reduction of its productive capacity. Therefore, this study aimed to assess the influence of tractor traffic intensification on soil physical attributes and soybean yield components. The st

18. Effects of Reduced and Conventional Tillage on Weed Communities: Results of a Long-Term Experiment in Southwestern Spain
RESUMO: Uma desvantagem importante na adoção de técnicas de cultivo mínimo (MT) e plantio direto (NT) é o deslocamento de plantas daninhas frequentemente observado, promovendo espécies adaptadas e, com isso, um controle de plantas daninhas mais precário. Essas mudanças só podem ser detectadas com experimentos de longo prazo, e os resultados podem di

19. Conservation Agriculture in Trouble? Estimating the Economic Impact of an Eventual Glyphosate Prohibition in Spain
RESUMO: O controle de plantas daninhas é um aspecto crucial em muitos sistemas de agricultura de conservação, uma vez que os custos e a economia de tempo de evitar o plantio direto estão intimamente ligados ao uso de herbicidas eficazes e ecologicamente corretos. Isso levou ao uso difundido de glifosato em fazendas administradas sob agricultura de conser

20. Interference of Volunteer Corn from Different Origins and Emergence Time on Soybean Yield and Stress Metabolism
RESUMO: A ocorrência de milho voluntário em soja é favorecida pelo cultivo de milho tolerante ao glyphosate antecedendo a soja e pelo sistema de semeadura direta. A interferência de milho voluntário causa significativas perdas no rendimento de grãos de soja. Os níveis de perdas no rendimento da cultura variam com a densidade do milho voluntário, orig

21. Maize cropping systems and response of common bean in succession subjected to nitrogen fertilization1
RESUMO A sucessão de feijoeiro com culturas consorciadas, no sistema plantio direto, é benéfica, sobretudo na busca por sustentabilidade. Além da produção de palhada, o consórcio de culturas pode fornecer nitrogênio (N) ao feijoeiro em sucessão, diminuindo o uso de adubo mineral, que é poluente e tem custo elevado. Objetivou-se avaliar a resposta �

22. Soil physical properties and soil organic carbon content in northeast Brazil: long-term tillage systems effects
ABSTRACT Concerns about the negative effects of agriculture on soil physical quality and soil organic carbon (SOC) pools have spurred on the adoption of conservation tillage systems in tropical regions. This study aimed to evaluate the long-term impacts (16th year) of conventional (CT), minimum (MT) and no-tillage (NT) practices and different cover crops (su

23. SOIL PHYSICAL ATTRIBUTES BEFORE AND AFTER MANAGEMENT UNDER SOWING FORWARD SPEED
ABSTRACT The soil management system affects physical attributes, and the forward sowing speed can increase or decrease its results. Thus, this work aimed to evaluate management systems before and after soil mobilisation and forward sowing speed on soil physical attributes. Thus, an experiment was conduct in a completely randomized block design with four repl

24. Chiseling and gypsum application affecting soil physical attributes, root growth and soybean yield
RESUMO O objetivo desse estudo foi avaliar o efeito da escarificação e da gessagem em atributos físicos do solo, crescimento de raízes e produtividade de grãos de soja. O experimento foi conduzido em Londrina, PR, em delineamento de blocos completos casualizados, com seis repetições. O solo da área experimental foi classificado como Latossolo Vermelh
