13. Nutritional aspects of potato plants for seed tuber production in protected condition / Aspectos nutricionais da batateira para produção de tubérculo-semente em ambiente protegido
In spite of its importance and the great number of studies on the potato (Solanum tuberosum L.) crop, in the tropical conditions the existing researches on mineral nutrition of the potato plant grown for seed tuber production, in field and in protected conditions, are scarce. The seed tuber production in protected conditions, as the system used by IAC (São

14. Balanço de nitrogênio e enxofre no sistema solo-cana-de-açúcar no ciclo de cana-planta / Nitrogen and sulfur balance in the soil-sugarcane system during the plant cane cycle
This works objective was to evaluate the use and distribution of nitrogen and sulfur added to the soil as fertilizers in the soil-sugarcane system (plant cane), using the stable isotopes 15N and 34S. The study also aimed to evaluate the contribution of nitrogen mineralized from sugar cane crop residues labeled with 15N and incorporated into the soil, in a co

15. Growth and mineral nutrition of soybean due to P, S, K, Ca and Mg excess in nutrient solution / Crescimento e nutrição mineral da soja submetida a excesso de P, S, K, Ca e Mg em solução nutritiva
Um sistema de cultivo eficiente depende do correto manejo da nutrição das plantas. Desordens nutricionais podem ser induzidas por manejo da fertilização inadequada e excessiva, dentre elas toxidez e deficiência induzida de um nutriente por outro. Com o objetivo de avaliar o comportamento da soja cultivar CD-208 ao excesso de cinco macronutrientes em sol

16. Sulfur-containing aminoacids, digestible lysine and threonine for light commercial layers at peak production. / AminoÃcidos sulfurados, lisina e treonina digestÃveis para poedeiras comerciais leves em pico de produÃÃo
Three experimental trials were accomplished with the objective of evaluating the effects of the nutritional levels of total sulfur-containing aminoacids, digestible lysine and threonine on performance, internal and external quality and yield in the processing of eggs of white layers at peak production. 1080 layers of the Hy-Line â W36 strain were utilized,

17. Produção e nutrição mineral do capim-Tanzânia com variável disponibilidade de nitrogênio e cálcio / Tanzânia grass production and mineral nutrition related to the availability of nitrogen and calcium
Tanzânia grass may depend on calcium availability as nitrogen is changed in the substrate. The objective was to evaluate the changes in physiological, nutritional and productive parameters of this grass, when combined rates of nitrogen and calcium were supplied, and search for calcium deficiency related to the supply of this nutrient in the nutrient solutio

19. Crude protein reduction, digestible amino acids digestible lisine ratios and lysine levels in diets for Nile tilapia fingerlings / Redução de proteína bruta, relações aminoácidos digestíveis com a lisina digestível e níveis de lisina digestível em rações para alevinos de tilápia do Nilo
The current study was aimed at evaluate the effect of dietary crude protein reduction with amino acids supplementation and determine the requirements of methionine plus cytine, threonine and lysine, based on the ideal protein concept, in diets for reverted Nile tilapia fingerlings (Oreochromis niloticus), of the thailand line. Four trials were carried out at

24. Role of reduced sulfur compounds in nutrition of Propionibacterium acnes.
In a study of the nutritional requirements of Propionibacterium acnes, acid hydrolyzed casein was shown to be the preferred nitrogen source in a glycerol-salts medium. Of 22 individual amino acids tested, only cysteine supported growth in the glycerol-salts medium. This indicated a requirement not only for amino nitrogen but also for reduced sulfur. In the p
