1. EFEITO DO TEOR DE GLICEROL NO TRANSPORTE DE VAPOR D’ÁGUA ATRAVÉS DE FILMES DE TRIACETATO DE CELULOSE PRODUZIDOS A PARTIR DO APROVEITAMENTO DA PALHA DE MILHO (ZEA MAYS L.)
Glycerol is a plasticizer widely used due to its good plasticization efficiency, great availability, biocompatibility and low exudation. It is a renewable raw material that, when introduced in biodegradable films, promotes significant changes in its properties and, thus, guarantees a wide spectrum of application. In this work, corn straw was used to produce

2. Selectivity of registered pesticides for the corn crop on immature stages of Trichogramma pretiosum (Hymenoptera: Trichogrammatidae)
RESUMO Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) é parasitoide de ovos de lepidópteros praga no milho, Zea mays L. (Poaceae), no Brasil. Produtos químicos usados na agricultura podem ser tóxicos para este agente de controle biológico. O objetivo do presente estudo foi avaliar a longevidade, parasitismo e emergência de T. preti

4. Knowledge and Use of the Flora in a Quilombola Community of Northeastern Brazil
ABSTRACT An ethnobotanical survey was carried out in the Quilombola Community of Serra do Evaristo in the municipality of Baturité, Ceará state, Brazil. We interviewed 41 residents who provided information on the plants used, the types of use, the preparation methods, the purchase location of the plants and their knowledge source. One hundred and fourteen

5. Persistence of auxinic herbicides applied on pasture and toxicity for succeeding crops
ABSTRACT The aim of this work was to determine the persistence of auxinic herbicides applied on tropical pasture and toxicity for succeeding crops. The herbicides were applied in an area of dystrophic red‒yellow latosol with pasture infested of weeds. At 40, 80, and 280 days after application of herbicide, the soil samples were collected at depths of 0 to

6. CROP COEFFICIENT REGIONALIZATION FOR IRRIGATED AGRICULTURE PLANNING IN MARANHÃO STATE -BRAZIL
ABSTRACT: Irrigated agriculture has emerged as a necessary technology to achieve greater productivity, mainly by supplying the water requirements of agricultural crops in critical periods, especially for those regions where natural rainfall is insufficient to meet these requirements. The daily water consumption of crops is strongly influenced by local weathe

7. QUALITY OF SEED DISTRIBUTION AT DIFFERENT SPACES BETWEEN BASE AND INTERMEDIATE BASE
ABSTRACT The aim of this study was to analyze the influence of space between the base and intermediate base on quality of seed distribution with a horizontal seed plate. The experiment was carried out in 2012 at the Laboratory of Agricultural Mechanization of the State University of Ponta Grossa - PR, Brazil, using a sowing simulation device. The experimenta

8. Phytoextractor Potential of Cultivated Species in Industrial Area Contaminated by Lead
ABSTRACT: High growth rate is one of the criteria used for the selection of species to be used in metal phytoextraction programs. This study was carried out to characterize the growth characteristics of sunflower (Helianthus annuus L.), castor bean (Ricinus communis L.), corn (Zea mays L), and vetiver [Vetiveria zizanioides (L.) Nash] grown on a soil contami

9. Iron Availability in Tropical Soils and Iron Uptake by Plants
ABSTRACT Given the increase in crop yields and the expansion of agriculture in low fertility soils, deficiency of micronutrients, such as iron, in plants grown in tropical soils has been observed. The aim of this study was to evaluate Fe availability and Fe uptake by corn (Zea mays L.) plants in 13 different soils, at two depths. Iron was extracted by Mehlic

10. Efeito de coberturas vegetais e doses de nitrogênio em cobertura no trigo irrigado por aspersão em cerrado de baixa altitude
ABSTRACT Wheat production in the Brazilian cerrado faces major challenges, especially for not being a traditionally wheat region and the occurrence of hot and dry winters. The objective of this study was to evaluate the residual effect of the previous crops corn and Urochloa ruziziensis (R. Germ & Evrard), in single cropping and intercropping, with and witho

11. Soil attributes under different crop management systems in an Amazon Oxisols
AbstractSoil biological properties have a high potential for use in assessing the impacts of crop systems. The objective of this study is to evaluate the effects of cropping systems on the biological attributes of an oxisol in the Amazonian state of Pará. The treatments consisted of approximately 20-year-old secondary vegetation, recovered pasture, no-tilla

12. Use of organic compost produced from slaughterhouse waste as fertilizer in soybean and corn crops
Slaughterhouses generate large amounts of rumen content and its use as a fertilizer may offer an environmentally friendly strategy for its management. The effect of an organic fertilizer produced from slaughterhouse waste on the fertility of sandy and clayey soils as well as soybean yield (Glycine max L.) and corn (Zea mays L.) crops was evaluated.
