1. Incorporação de biomassa de fabáceas ao substrato de plantio para controle da podridão-de-escleródio (Sclerotium rolfsii) em cubiu (Solanum sessiliflorum)
RESUMO O cultivo do cubiu (Solanum sessiliflorum Dunal), no Amazonas, é limitado pela alta incidência da doença podridão-de-escleródio (Sclerotium rolfsii Sacc.) e a incorporação de material vegetal ao substrato de cultivo altera a microflora presente. O trabalho objetivou avaliar o potencial de controle da podridão-de-escleródio em cubiu por meio d

2. The Ecology and Conservation of Wild Rice, Zizania palustris L., in North America
Resumo O Arroz selvagem é uma espécie de planta enigmática da parte do centro-norte dos EUA. O arroz selvagem (Zizania palustris L.) é encontrado em muitos locais nessa região. Contudo, é uma espécie selvagem, mas ao mesmo tempo produzida de forma semi-domesticada. É uma planta enigmática porque é produzido e colhido em grandes alagados por fazend

3. Riparian forest fragments in rice fields under different management: differences on hymenopteran parasitoids diversity
Resumo Os himenópteros parasitoides são importantes agentes de controle biológico em agroecossistemas com sua diversidade variando de acordo com a heterogeneidade de habitat. Nesse sentido, o objetivo deste trabalho foi avaliar a influência da distância de áreas com fragmentos de vegetação natural das áreas de cultivo de arroz, o tipo de manejo (org

4. Performance of Flooded Rice Grown in Succession to Winter Cover Crops
ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase

5. Responses of water mite assemblages (Acari) to environmental parameters at irrigated rice cultivation fields and native lakes
ABSTRACT Many studies have revealed that water mite communities can be affected by the physical and chemical parameters of the water. The similarity between the water ‘mite assemblages in local water bodies and in irrigated rice areas can be a way to measure the water conditions, enabling an assessment of the anthropic impact in the environment. The aim of

6. Characterization of new sources of derivative starches as wall materials of essential oil by spray drying
Starch derivatives of taro (Colocasia esculenta L. Schott) and rice were characterized as wall materials of orange oil (d-limonene) by spray drying. Native starches were initially hydrolyzed with HCl and then esterified. Succinylated starches were modified using a conventional method in a slurry and were extruded; whereas, the phosphorylated starches were mo

7. Metabolic, productive and reproductive responses to postpartum short-term supplementation in primiparous beef cows
The objective of this study was to evaluate the effect of a short-term supplementation with rice bran (2 kg/cows/day) on the endocrine and metabolic profiles and hepatic gene expression, associated with the reproductive response in beef cows in grazing conditions. Thirty-eight primiparous beef cows (Hereford, Angus and Hereford × Angus) were used in a rando

8. Biological control of rice brown spot with native isolates of three Trichoderma species
Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened aga

9. Genetic variability for disease resistance in Brazilian upland rice native germplasm.
Thirty nine rice genotypes were evaluated under dryland field conditions for resistance to leaf and neck blast, brown spot, leaf scald, narrow brown leaf spot and grain discolaration in 13 test sites during a three-year period. these include 17 land races, six traditional cultivars, 11 improved breeding lines and three exotic cultivars. There was a great div

11. Rhizobia selection and nitrogen efects in the symbiosis with alfafa and birdsfoot / Seleção de rizóbios e efeito do nitrogênio na simbiose com alfafa e cornichão
Alfalfa and birdsfoot forages are important plants used during the pastures¿ hibernal period of Rio Grande do Sul, gathering desired traits such as high nutritional value, high forage production, good acceptability and digestibility. However, in Brazil, there is a lack of studies aiming the selection and characterization of Rhizobium strains in alfalfa and
