1. VOLATILE COMPOUNDS IN CACHAÇAS OBTAINED FROM THREE SUGARCANE VARIETIES CULTIVATED UNDER THE MANAGEMENTS: ORGANIC, CONVENTIONAL AND WITHOUT FERTILIZATION
The volatile compounds present in cachaça can derive from the raw material used in the production of the beverage, from the fermentative process, from distillation or aging. The aim of the research was to evaluate the volatile compounds, in the cachaças from stills produced with different sugarcane varieties, under the organic and conventional managements.

2. Foliar application of molybdenum on cover crops and response of common beans in successive cultivation
ABSTRACT The effects of foliar application of Mo and use of N from cover crops (Crotalaria juncea L. and Canavalia ensiformis (L.) DC) on the performance of common beans were investigated in this study. Field experiments were carried out in a succession planting system (cover crops - common beans), and nitrate reductase activities were evaluated in the labor

3. Monitoring the content of ethyl carbamate and copper in organic and conventional cachaça
ABSTRACT: Ethyl carbamate (EC) (NH2COOCH2CH3) is found in cachaça, and its presence in the beverage is conspicuous for its toxicity. Copper, the metal of choice used in the construction of stills, is also considered a beverage contaminant and is often related to the presence of EC in beverages. The study aimed to monitor the quality of cachaça by measuring

5. Growth and nutrient accumulation in the aerial part of red Pitaya (Hylocereus sp.)
Resumo O conhecimento das quantidades de nutrientes acumulados pela pitaia nas diferentes fases de desenvolvimento permite definir as épocas em que os elementos essenciais são mais exigidos, contribuindo assim para a elaboração de programas de adubação racionais para a cultura, diminuindo os custos de produção. Objetivou-se com este trabalho avaliar

6. MORPHOLOGICAL, PRODUCTIVE, AND CHEMICAL TRAITS OF XARAÉS GRASS: NITROGEN TOPDRESSING VERSUS INOCULATION WITH DIAZOTROPHIC BACTERIA
Resumo A adubação nitrogenada em cobertura é imprescindível para a produção de forragem, mas o elevado custo dos fertilizantes estimula a busca por novas tecnologias, como o uso de bactérias diazotróficas, que podem fixar o nitrogênio atmosférico. Para avaliar o potencial dessa tecnologia em suprir a quantidade de nitrogênio requerida pelo capim-x

9. Nitrate Reductase Activity and Nitrogen and Biomass Accumulation in Sugarcane under Molybdenum and Nitrogen Fertilization
ABSTRACT Prior research on sugarcane showed increment of productivity following molybdenum (Mo) fertilization and some indication of the potential role either on nitrate reductase activity (NRA). However, this increment can depend on sugarcane variety and nitrogen (N) fertilization. This study aimed to evaluate the effect of Mo fertilization on Mo uptake, on

10. Growth and Quality of Leucochloron incuriale Seedlings Subjected to Liming and Phosphorus
ABSTRACT Leucochloron incuriale can be used in projects to restore degraded areas and for logging purpose. Soil has been used in nurseries to produce seedlings; however, most soil types in Brazil have low nutrient availability and high acidity level. The aim of the current study is to assess the effect of liming and phosphate fertilization on the growth and

11. Benchmark: Biomass Production in Eucalyptus Plantations as a Consequence of Fertilization
ABSTRACT The objective of this work was to evaluate the effects of fertilization, spatial arrangement and age on the biomass production in eucalyptus. The experiment was set up in a randomized block design with four replicates. Overall, 15 fertilizations adopted by forest companies in plots were evaluated, and two arrangements, 3.0 x 3.0 m and 6.0 x 1.5 m,

12. Initial Growth of Pinus taeda by Fertilization Response at Planting
ABSTRACT The objective of this study was to evaluate how the fertilizer composition, type and application method contribute to the initial growth of Pinus taeda applied at planting. Seedlings from an open-pollinated seed orchard of Pinus taeda were planted on a Humic Dystrudepts soil containing 15 treatments of fertilizer application at planting. Basal diam
