1. Control of Italian ryegrass and Alexandergrass in corn using different corn sowing date, pre- and post-emergent herbicides
ABSTRACT Glyphosate-resistant (GR) Italian ryegrass (LOLMU) and Alexandergrass (URPLA) are troublesome weeds in corn cropping systems in Southern Brazil. The emergence pattern of those weeds is not uniform and may change according to the season’s environmental characteristics. Also, herbicide resistance has been diminishing the success of the weed control

2. Tillering dynamics of Alexandergrass pasture under nitrogen fertilization
RESUMO Esse estudo foi conduzido para avaliar o efeito da fertilização nitrogenada no perfilhamento do Papuã (Urochloa plantaginea (Link) Hitch) pastejado por novilhas de corte em um método de lotação rotacionada. O delineamento foi inteiramente casualizado com arranjo de medidas repetidas, três níveis de nitrogênio (Zero, 150 e 300kg ha -1 ) e dua

3. Grazing height targets for Alexandergrass pastures under continuous stocking in integrated crop-livestock system
RESUMO: O objetivo deste trabalho foi identificar alturas de manejo para pastos de papuã sob lotação contínua em sistemas de integração lavoura-pecuária (ILP). Para tanto, doze pastos foram cultivados em uma área de ILP e mantidos em 10, 20, 30 ou 40 cm por meio de lotação contínua com caprinos. As seguintes variáveis foram analisadas: massa; ta

4. ESTRUTURA DO DOSSEL E COMPORTAMENTO INGESTIVO DE CAPRINOS EM PASTOS DE PAPUÃ MANEJADOS SOB LOTAÇÃO CONTÍNUA
Resumo O objetivo deste estudo foi descrever a estrutura do dossel e o comportamento ingestivo de caprinos em pastos de papuã manejados sob lotação contínua. Os tratamentos corresponderam a quatro alturas de manejo (10, 20, 30 e 40 cm) mantidas através de taxa de lotação variável. As variáveis analisadas foram: composição morfológica, massa e den

5. Leaf tissue flows and defoliation patterns of Alexandergrass grazed by heifers receiving energy supplement
ABSTRACT. The study was carried out to evaluate defoliation patterns and to quantify leaf tissue flows in Alexandergrass (Urochloa plantaginea (Link.) Hitch) grazed by beef heifers receiving whole rice bran in three levels of supplementation (0, 0.5 and 1 % of body weight). A rotational stocking grazing method and two area replications were utilized. The exp

6. Sward structure and nutritive value of Alexandergrass fertilized with nitrogen
Nesse experimento objetivou-se estudar a produção de forragem, estrutura do dossel, taxa de lotação, ganho de peso por área e o valor nutritivo da forragem aparentemente consumida por bezerras de corte em pastagem de papuã (Urochloa plantaginea (Link) Hitch) adubada com nitrogênio (N): 0; 100; 200 ou 300 kg/ha.

7. Ingestive behavior, performance and forage intake by beef heifers on tropical pasture systems
The experiment was carried out to evaluate forage intake, performance and ingestive behavior of beef heifers. Productive, structural and chemical characteristics of the pasture were also evaluated. The experimental design was completely randomized in a 3 × 2 factorial arrangement, with three pasture systems (Alexandergrass [Urochloa plantaginea Link.] with

8. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments

9. EFEITO DE FREQUÊNCIAS DE SUPLEMENTAÇÃO NO COMPORTAMENTO INGESTIVO, PADRÃO DE DESLOCAMENTO E INGESTÃO DE MATÉRIA SECA POR NOVILHAS DE CORTE / The effects of several supplementation frequencies on ingestive behavior, displacement patterns and dry matter intake by beef heifers
The dry matter intake, ingestive behavior and displacement patterns were evaluated on beef heifers exclusively on pasture or receiving oats grain daily (frequent) or from Monday to Friday (infrequent) in "Vegetative" and "Reproductive" phenological stages of Alexandergrass (Urochloa plantaginea Link.). The grazing method was continuous with a variable number

10. Productivity and reproductive performance of grazing beef heifers bred at 18 months of age
The experiment was carried out to evaluate the performance and body development of beef heifers reared from 15 to 18 months of age on Pearl millet (Pennisetum americanum), Alexandergrass pasture (Urochloa plantaginea) or native pasture invaded by Annoni-2 grass (Eragrostis plana Nees). The experimental design was completely randomized following a repeated me

11. COMPORTAMENTO INGESTIVO E CONSUMO DE FORRAGEM POR NOVILHAS DE CORTE EM SISTEMAS FORRAGEIROS DE CICLO ESTIVAL / INGESTIVE BEHAVIOUR AND FORAGE INTAKE BY BEEF HEIFERS IN TROPICAL PASTURE SYSTEMS
ABSTRACT There were evaluated forage intake, ingestive behavior, productive, structural and chemical characteristics of pasture and performance of beef heifers in coastcross (Cynodon dactylon (L.) Pers) and alexandergrass(Urochloa plantaginea Link.) receiving protein supplement or not. The grazing method utilized was continuous with variable number of animal

12. USO DE PASTAGEM DE GRAMÍNEAS DE ESTAÇÃO QUENTE NA RECRIA DE NOVILHAS DE CORTE / SUMMER GRASS PASTURES UTILIZATION FOR BEEF HEIFERS
The experiment was carried out to evaluate attributes of pastures and relazed to ingestive behavior, the animal performance and reproduction of beef heifers reared from 15 to 18 months and bred at 18/20 months of age. In observations of ingestive behavior were evaluated heifers on Pearl millet (Pennisetum americanum) and alexandergrass (Urochloa plantaginea)
