1. Growth and regrowth of tough lovegrass (Eragrostis plana Nees)
This study evaluated the morphological development of two populations of tough lovegrass during 120 days of continuous growth (Experiment I), and the regrowth of one population under the combination of cutting height (5 cm and 10 cm) and phenological stage at the first cutting (vegetative and beginning of flowering; Experiment II). In Experiment I, plants we

2. Classes de perfilhos na composição do índice de área foliar em pastos de capim-elefante
O trabalho foi conduzido de outubro de 2002 a abril de 2003, em Coronel Pacheco, MG, com o objetivo de avaliar os efeitos da altura do resíduo pós-pastejo (50 e 100 cm) sobre a radiação fotossinteticamente ativa (RFA) interceptada pelo dossel e o coeficiente de extinção luminosa; a contribuição relativa de classes de perfilhos (basais e aéreos) sobr

3. Estratégias de suplementação energética para bovinos em recria em pastagens tropicais durante as águas e seus efeitos na terminação em confinamento / Energetic supplementation strategies for growing cattle grazing tropical forages during the raining season and their effects on the feedlot finishing phase.
The objective of this study was to evaluate the effect of strategies of feeding an energetic supplement to growing cattle, grazing well managed tropical pastures during the rainy season, on the grazing animal performance, pasture stocking rate, total body weight gain per area, and on feedlot finishing phase. The treatments tested were: T1) Control: animals f

4. Respostas morfofisiológicas e produtivas de genótipos de Pennisetum purpureum Schum. de porte baixo sob lotação intermitente de ovinos na Zona da Mata de Pernambuco
The research was conducted at the Experimental Station of the Agronomic Institute of Pernambuco (IPA) located in Itambé, dry rainforest region of Pernambuco. The objective was to estimate the coefficients of repeatability, of determination (R2) and the number of measures needed to predict the real value [using principal component analysis (PCA)] to variable

5. Xaraés palisadegrass under grazing: agronomic, morphological, and physiological responses, and adapting the CROPGRO model for predicting forage growth / Capim Xaraés sob pastejo: respostas agronômicas e morfofisiológicas, e adaptação do modelo CROPGRO para a predição de crescimento
On optimization of the animal production systems using models, morphological and physiological aspects of forage plants is required. Moreover, is necessary to understand grazing effects on regrowth, and consequently, on forage mass accumulation. The objective of this research was to evaluate the morphological and physiological responses, and adapting the CRO

6. Efeito do manejo do solo com plantas de cobertura, cultivares/híbridos e nitrogênio na cultura do milho / Effect of soil management with soil cover plants, hybrids and dose of nitrogen in the productivity of corn
The corn is the main cereal produced in Brazil and its productivity is very affected by the improper use of nitrogen, which is the nutrient absorbed in larger quantities and therefore responsible for a significant share in production costs. Due to the importance of nitrogen for the corn crop becomes necessary studies to reduce the amount of nitrogen applied

7. Respostas de bovinos de corte à suplementação energética em pastos de capim-marandu submetidos a intensidades de pastejo rotativo durante o verão / Beef cattle responses to energetic supplementation on Marandu palisadegrass pastures subjected to rotational grazing with different stubble heights during the summer
Adequate grazing management and supplementation practices can increase yield and economical competitiveness of the production system. The purpose of this work was to evaluate the performance of beef cattle on Brachiaria brizantha pastures (Marandu palisadegrass) subjected to rotational grazing managed with different stubble heights (10 vs 15cm), using an ene

8. Produção de forragem de capins do gênero Panicum e modelagem de respostas produtivas e morfofisiológicas em função de variáveis climáticas. / Forage yield of Panicum grasses and modeling yield, morphological and physiological traits in response to climatic variables.
The brazilian livestock industry is based on the use of tropical pastures with high production potential which benefits from favorable environmental conditions over the year. However, the seasonal pattern of climatic conditions, mainly temperature and daylength, concentrates most of the annual forage accumulation during the spring and summer. Thus, knowing t
