3. DETERMINATION OF XARAÉS GRASS QUALITY SUBMITTED TO IRRIGATION WATER LEVELS AND NITROGEN AND POTASSIUM DOSES
ABSTRACT In the correct pasture management, nutritional factors such as nitrogen and potassium fertilization play an important role in the forage production and quality. The aim was to evaluate the effects of the application of water levels, nitrogen and potassium doses in the Xaraés grass in the south of the State of Tocantins. For this, Xaraés grass was

4. Avaliação de métodos para análise de nitrogênio amoniacal em fluido ruminal e de óxido crômico em amostras de fezes de bovinos / Evaluation of methods for analyses of ammonia nitrogen in rumen fluid and chromium in cattle feces
This dissertation was based on two different experiments. The first one was conducted to evaluate the accuracy of two different methods in measuring the ammonia nitrogen (N-NH3) concentration in rumen fluid: a catalyzed indophenol colorimetric reaction (CICR) and the Kjeldahl distillation (KD). Five buffered standard solutions containing volatile fatty acids

5. Root system characteristics of Marandu palisadegrass supplied with nitrogen and magnesium rates
The development of root system of forage grasses is influenced by the supply of mineral nutrients. The experiment was carried out in a greenhouse in Piracicaba, São Paulo State, with the objective of evaluating the effect of nitrogen and magnesium rates on dry mass yield, total length and surface, specific length and surface, and concentrations of nitrogen,

6. Productive, nutritional and metabolic characteristics of marandu palisadegrass grown with nitrogen and magnesium rates / Características produtivas, nutricionais e metabólicas do capim-marandu submetido a doses de nitrogênio e magnésio
Productive, nutritional and metabolic characteristics of the forage plants may be changed by the nitrogen and magnesium availability. The objective was to study the effects of nitrogen and magnesium rates on marandu palisadegrass growth, by evaluating the shoot and root yield, leaf and root concentrations of nutrients and leaf concentration of inorganic form

7. Suprimento de nitrogênio e de potássio e características morfogênicas, nutricionais e produtivas do capim-Marandu / Nitrogen and potassium supply and the morphogenetic, nutritional and productive characteristics of Marandu palisadegrass
Nitrogen and potassium are essentials for plant development, are extracted by plants in high amounts and their availabilities may change the morphogenetic, productive and nutritional characteristics of plants. The objectives of this research were: a) to assess fertilization with nitrogen and potassium rates on morphogenetic and shoot and root dry matter prod

8. Doses de nitrogênio e de enxofre para a recuperação de pastagem com capim-braquiária: atributos de parte aérea, raízes e fertilidade do solo / Nitrogen and sulfur rates for a Signal grass pasture recovery: forage aboveground and roots, and soil fertility attributes
Fertilizer application has been essential to pastures establishment, maintenance and recovery, whereas sulfur supply may be inadequate for grasses receiving high nitrogen rates. The objectives were to study the effects of combined nitrogen and sulfur rates in a degrading Signal grass (Brachiaria decumbens) pasture, by evaluating productive, morphological, ph

9. Effects of Different Levels and Combinations of Nitrogen and Potassium Content in the Seed Oil of Castor bean (Ricinus communis L.) irrigated with sewage and raw water treaty. / Efeitos dos Diferentes NÃveis e CombinaÃÃes de NitrogÃnio e PotÃssio no Teor de Ãleo da Semente da Mamona (ricinus communis l.) Irrigada com Esgoto SanitÃrio tratado e Ãgua bruta.
A mamoneira (Ricinus communi Linn) Ã uma planta bem adaptada Ãs condiÃÃes de semi-aridez, sendo considerada um grande potencial econÃmico para a RegiÃo Nordeste. A irrigaÃÃo com esgoto domÃstico tratado Ã, tambÃm, considerada uma alternativa para as regiÃes com escassez hÃdrica, devido ser uma fonte de Ãgua para essas regiÃes, alÃm de proporc
