2. Impact of agro-farming activities on microbial diversity of acidic red soils in a Camellia Oleifera Forest
ABSTRACT The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, r

3. Metabolism of carbohydrates in Estilosantes cv. Campo Grande under different systems of cultivation and nitrogen fertilization
ABSTRACT. The objective of this study was to verify the activity of invertases in Estilosantes under the influence of cultivation systems and nitrogen fertilization in two seasons. The experiment was conducted in the Xaraés area, where Estilosantes was planted according to a 2 x 2 factorial scheme with two cultivation systems (monoculture and mixed pasture)

5. Evaluation of soybean breeding lineages to new sources of root-knot nematode resistance
RESUMO No Brasil, as perdas causadas pelos nematoides aumentaram nas áreas produtoras à medida que a cultura da soja se expande. Portanto, este trabalho teve como objetivo desenvolver uma nova cultivar de soja não geneticamente modificada que combinasse características como resistência a nematoides, maturação precoce, alta produtividade de grãos e al

6. Response of elephant grass to grazing under an organic production system
RESUMO O objetivo desta pesquisa foi avaliar o capim elefante nos sistemas orgânico e convencional. No sistema orgânico, combinaram-se espécies com períodos de crescimento complementares; o capim elefante foi plantado em linhas com 3,0 m de distância entrelinhas; entre as fileiras de capim elefante, durante o período hibernal, foi semeando o azevém e

7. Seasonal abundance of Henosepilachna vigintioctopunctata (Fab.) on Solanum melongena L. and natural occurrence of its two hymenopteran parasitoids
ABSTRACT The 28-spotted hadda beetle Henosepilachna vigintioctopunctata Fab. (Coleoptera: Coccinellidae) is a poly-phagous pest, commonly infesting solanacious crops including brinjal, Solanum melongena L. Upon its severe infestation on brinjal, it causes considerable damage to the foliage and also to the calyx of fruits. The studies were made to record the

8. Avaliação do metabolismo primário da região cambial e casca de Eucalyptus grandis / Evaluation of the primary metabolism of Eucalyptus grandis cambial region and bark
Eucalyptus genus is the most widely planted hardwood crop in the world because of its superior growth, broad adaptability and multipurpose wood properties. In today\ s \"new carbon economy\", eucalypts are receiving attention as fast-growing, short-rotation, renewable biomass crop for energy production. In spite of its economical importance, little informati

9. Influence of row spacing reduction on maize grain yield in regions with a short summer.
The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in t

10. Consórcio de milho com adubos verdes e manejo da adubação nitrogenada no cultivo de feijão em sucessão no sistema integração lavoura-pecuária no cerrado / Nitrogen fertilization management in bean cultivated after maize-legumes intercropping in the Crop-Livestock Integration system in Brazilian Savannah
Ten experiments were performed involving common beans and maize intercropped with legumes and/or Brachiaria brizantha, in the summer crops of 2008/2009, 2009 winter and summer of 2009/2010 in two municipalities in the Goiás (GO) state, Brazil. In Ipameri- GO, the area was planted with soybeans for several years and corn associated with B. brizantha in crop

11. Weeds supression and agronomic characteristics of corn crop under leguminous residues in no-tillage system / SupressÃo de plantas invasoras e caracterÃsticas agronÃmicas da cultura do milho sob resÃduos culturais e leguminosas em sistema plantio direto
The use of cover crops on no-tillage system can add several advantages, such as controlling the weeds population. The leguminous species also carry out biological nitrogen fixation, increase nutrients to the soil and bring other benefits. Therefore, this research aimed at testing the leguminous, dwarf mucuna beans, dwarf pigeon pea and stylosanthes on seedli
