13. Influence of Phenology and Post-Harvest Processing of Vegetal Material on the Allelopathy of Annoni Grass (Eragrostis plana) Extracts
RESUMO: O estádio fenológico da planta, a quantidade e o processamento do material vegetal são fatores que podem interferir na atividade alelopática dos extratos. Este trabalho teve como objetivo testar o efeito alelopático de extratos aquosos de folhas de capim-annoni (Eragrostis plana), invasora de pastagens naturais. Doze extratos foram elaborados, r

14. Estimativa da correção do coeficiente de retorno de esgoto sanitário em habitações com sistemas de aproveitamento de água pluvial: estudo de caso da cidade de Bauru, SP
RESUMO O coeficiente de retorno (f) da rede coletora de esgoto, que apresenta quociente dado pelos volumes água/esgoto micromedidos, é empregado no projeto e na gestão do sistema de coleta de esgoto sanitário. As fontes de suprimento de água alternativas, tais como águas de reúso e de aproveitamento pluvial, não estão contempladas por f. O presente

15. Insights on Structuration of Peroxotungstic Acid in Aqueous Media
Recent studies on tungsten oxide preparation are mainly motivated by its applications in smart windows, energy harvesting and, recently, in cancer therapy. Peroxotungstic acid (PTA) is an important precursor to obtain tungsten oxide in an environmentally-friendly way, through the colloidal synthesis in aqueous media. Despite giving chemically pure products,

16. Potassium Fertilization of Eucalyptus in an Entisol in Low-Elevation Cerrado
ABSTRACT Potassium (K) is one of the most highly accumulating nutrients in Eucalyptus and, consequently, is heavily exported by the harvesting of wood. Moreover, its availability in the soil in most Brazilian plantation areas is very low, especially in the regions of the Cerrado biome, which has soils with low natural fertility and marked water deficits, imp

17. Straw removal of sugarcane from soil and its impacts on yield and industrial quality ratoons
ABSTRACT: Mechanical harvesting leaves in its wake a considerable amount of straw in the field, which can be effectively utilized to improve the soil condition and sugarcane yield. However, there is no specific information as to the quantity of straw mulch required to achieve such effects and as to whether it can be used in other sectors for bioelectricity a

18. Correlation between water activity and moisture content of Turkish flower and pine honeys
Abstract Water activity (aw) and moisture content (MC) of Turkish liquid flower and pine honeys were determined. Samples (706 flower and 257 pine) were collected during the honey harvesting seasons of 2010-2014 from 137 apiaries in locations with different climatic conditions all over the land. Up to date, this work is the first one seeking for a correlation

20. Shoot and root interference of morning glory on the initial growth of sugarcane
ABSTRACT Among weeds, morning glories comprise a very important group of climbing plants that infest sugarcane crops. The objective of this study was to evaluate the shoot and root interference of Merremia cissoides on the initial growth of sugarcane cultivar RB 966928. The experiment consisted of five treatment groups: (i) sugarcane monocropping, (ii) morni

21. QUALITY OF MECHANICAL SOYBEAN HARVESTING AT TWO TRAVEL SPEEDS
ABSTRACT: Soybean harvesting is the last operation performed in the field and therefore has high added value. Quantitative losses during this process should therefore be minimized to achieve maximum quality and increase the sustainability of the production system. The aim of the present study was to determine and characterize the quantitative losses and oper

22. INFLUENCE OF THE PLOTS FORMAT ON THE PERFORMANCE INDEX OF THE SOYBEAN COMBINE HARVESTER
ABSTRACT: The intensive mechanization during the harvest operation and success of this operation depends on several factors, one of which is the length and format of the plots. The aim of this study was to evaluate the operating performance of a soybean harvester in different geometric plots shape, using as quality indicators performance parameters by means

23. Genetic control of viviparity in common bean
ABSTRACT: In common bean (Phaseolus vulgaris) harvesting is carried out in the field. It is therefore necessary that cultivars be tolerant to viviparity, i.e., germination of grains still in the pods. Study of the percentage of germination of beans in the pods under laboratory conditions, where humidity content is high, has been proposed. Furthermore, under

24. Assessment of sugarcane harvesting residue effects on soil spectral behavior
ABSTRACT When the harvesting of sugarcane involves a mechanized process, plant residues remain on the soil surface, which makes proximal and remote sensing difficult to monitor. This study aimed to evaluate, under laboratory conditions, differences in the soil spectral behavior of surface layers Quartzipsamment and Hapludox soil classes due to increasing lev
