13. Classificação não-supervisionada no delineamento de zonas de manejo.
RESUMO: O objetivo deste trabalho foi utilizar o método de classificação não-supervisionada (fuzzy K-means) em dados de produtividade para delineamento de zonas de manejo. O estudo foi conduzido a partir de dados georregerenciados de produtividade de grãos coletados por sensores e DGPS. Foram mapeadas três safras (milho-soja-arroz) em área de plantio

14. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

15. Avaliação do impacto da variabilidade/mudanças climáticas sobre Euschistus heros, Telenomus podisi e ferrugem asiática na soja, no Região Sul do Brasil / Risk assessment of variability/climate change on the Euschistus heros, Telenomus podisi and asian soybean rust of soybean, in the southern region of Brazil
Brazil is the second largest soybean producer, however, biotic and abiotic factors affect the crop, causing serious damage, with significant economic impact. Among these problems, Euschistus heros and asian soybean rust. For biological control of the insects, the parasitoid Telenomus podisi has been described as one of the potential agents in MIP programs. T

16. Variabilidade espacial da matéia orgânica em um latossolo vermelho-amarelo sob cafeeiro conilon
The aim of this study was to evaluate the spatial variability of total organic carbon and organic carbon of humic substances in an Oxisol under conilon coffee in plains, which were planted in different periods of time. The study was conducted in an area which belongs to Espírito Santo State Research, Technical Assistance and Rural Extension (INCAPER), locat

17. Mapping QTLs for traits associated with biological nitrogen fixation (BNF) in soybeans / Mapeamento de QTLs para caracteres relacionados com a fixação biológica de nitrogênio (FBN) em soja
Soybeans [Glycine max (L.) Merrill] is a crop with high protein content (about 40%) in the seeds. As a result, the crop demands high nitrogen (N) inputs, which can be supplied by the process of biological nitrogen fixation (BNF), through the symbiosis with bacteria of the genus Bradyrhizobium. In Brazil the BNF allows to fulfill all the demand for N; therefo

18. Metodologia para o mapeamento da cultura da soja no estado do Rio Grande do Sul utilizando imagens de sensor de moderada resolução espacial / Methodologies for mapping the soybean crop in the state of Rio Grande do Sul using images of moderate spatial resolution sensor
O aumento progressivo da demanda mundial por alimentos e a disponibilidade de vastas áreas agrícolas têm servido de estímulo e reforço para o aumento da produção agropecuária que muitas vezes, não considera a capacidade ecológica de suporte dos ambientes e as consequências sociais e econômicas de um crescimento desequilibrado. Em relação às á

19. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima

20. Sugarcane crop efficiency in the State of São Paulo between growing seasons of 1990/1991 and 2005/2006. / Eficiência da produção agrícola de cana-de-açúcar no Estado de São Paulo entre as safras 1990/1991 e 2005/2006
The sugarcane is an important resource for food and energy production with scale to help the economy of fossil fuels and the development of new guidelines for socio-economic development in sustainable basis. The State of São Paulo is a region of great potential to meet the sugarcane demand in terms of sugar, ethanol and energy, since it has a long tradition

21. Construction of cowpea genetic map using ISSR, DAF e CAPS markers / ConstruÃÃo de um mapa genÃtico para feijÃo-caupi com marcadores moleculares ISSR, DAF E CAPS
Cowpea crop is of great economical importance in Brazil being the Northeastern region the main producer. The low levels of resistance to pathogens is one of the restricting factors for the Brazilian competitiveness worldwide. One of the most important disease is caused by Cowpea severe mosaic virus - CPSMV. The control of CPSMV can be achieved whit the use o

22. Mapeamento de areas de cafe no municipio de Guaxupe/MG por meio de processamento digital de imagens Landsat / Coffee crop areas mapping in mountain relief through Principals Components Analysis
The economic importance of Brazilian coffee growing in the world market is notorious and makes up significant portion of the country s foreign trade exports. Minas Gerais stands out as the core of Brazilian coffee growing, with most of the planting areas (Coffea arabica) concentrated in the south, where it is grown in small plots widely spread throughout the

23. Environmental characterization and land-use condition of the landscape of São Félix do Araguaia municipality / Caracterização ambiental e condição do uso da terra da paisagem do município de São Félix do Araguaia MT
There is an increase need for remote sensing data and associated analysis techniques in detecting and monitoring landscape change, particularly for resource management and planning. Information derived from remote sensing spatial data landscape has often been used to assist in the formulation of policies and provide insight into land-use patterns. To underst

24. Spectral-temporal classification of orbital images to map sugarcane with pre-harvest straw burning / Classificação espectro-temporal de imagens orbitais para o mapeamento da colheita da cana-de-açúcar com queima da palha
In order to reduce the time established by law to cease the pre-harvest burning of sugarcane from 2021 to 2014, the Environmental Secretary of São Paulo State (SMA-SP) and the Sugarcane Industry Association (UNICA) signed, in June 2007, an Agro-Environmental protocol of intentions. Therefore, the monitoring of the sugarcane crop, with and without the practi
