25. Forage yield and nitrogen nutrition dynamics of warm-season native forage genotypes under two shading levels and in full sunlight
The successful achievement of a highly productive understorey pasture in silvopastoral systems depends on the use of well-adapted forage genotypes, showing good agronomic performance and persistence under shading and grazing. In this study, the herbage dry matter yield (DMY) and nitrogen nutrition dynamics were determined in three native warm-season grasses

26. Chemical composition and photosynthetically active radiation of forage grasses under irrigation
The present study aimed to estimate the photosynthetically active radiation of tropical forage grasses in ten cutting dates, under irrigation. The following treatments were used: Brachiaria decumbens grass (Brachiaria decumbens cultivar Basilisk), Marandu grass (Brachiaria brizantha cultivar Marandu), Xaraes grass (Brachiaria brizantha, cultivar Xaraes), Mom

27. Impact of nitrogen fertilization on the forage characteristics and beef calf performance on native pasture overseeded with ryegrass
The overseeding of ryegrass (Lolium multiflorum Lam) on sub-tropical native pastures increases the availability and quality of forage in the cold season. However, soil chemical amendment and nitrogen use can affect the floristic composition, with consequences to the primary and secondary production. In a randomized complete block design with three replicatio

28. Dry matter production and nitrogen use efficiency of giant missionary grass in response to pig slurry application
This study assessed the effect of successive applications of pig slurry on the dry matter (DM) production and the nitrogen use efficiency of giant missionary grass along two years. A total of 55, 110, 165, 220 and 275 m³ of pig slurry/ha/year were applied in order to supply 100, 200, 300, 400 and 500 kg of total N/ha/year, respectively. These treatments wer

29. Rehabilitation with forage grasses of an area degraded by urban solid waste deposits
Dry matter yield and chemical composition of forage grasses harvested from an area degraded by urban solid waste deposits were evaluated. A split-plot scheme in a randomized block design with four replicates was used, with five grasses in the plots and three harvests in the subplots. The mineral content and extraction and heavy metal concentration were evalu

30. Evaluation of sodium sulfite and protein correction in analyses of fibrous compounds in tropical forages
The objective of this study was to evaluate the contents of fibrous compounds in tropical grasses and legumes according to utilization of sodium sulfite in the neutral detergent solution or using a procedure for contaminant protein correction. Samples of ten grasses and ten legumes were used. The contents of neutral detergent fiber were decreased when sodium

31. Desempenho agronômico e análise de crescimento de capins do gênero Cynodon em resposta à frequência de corte / Agronomic performance and growth analysis of Cynodon grasses in response to harvest frequency
O presente trabalho teve o objetivo geral de estudar as respostas produtivas de capins do gênero Cynodon em resposta a estratégias de corte. O experimento foi conduzido no campus da ESALQ em Piracicaba, SP. Foram avaliados três cultivares, Tifton 85 e Jiggs (estabelecidos vegetativamente) e Vaquero (propagado por sementes) submetidos a três intervalos de

32. Modificações na estrutura do dossel, comportamento ingestivo e composição da dieta de bovinos durante o rebaixamento do capim-mulato submetido a estratégias de pastejo rotativo / Modifications in sward structure, ingestive behaviour and diet composition of cattle during grazing of mulato grass subjected to strategies of rotational stocking managment
Durante o rebaixamento ocorrem modificações muito rápidas na estrutura do dossel forrageiro, fato que afeta os padrões de deslocamento, procura e ingestão de forragem, os padrões de desfolhação e seletividade e a composição da dieta consumida. Contudo, essas variações podem ser manipuladas por meio de ajustes na frequência e severidade de pastej

34. Carbonate-silicate ratio for soil correction and influence on nutrition, biomass production and quality of palisade grass
Silicates can be used as soil correctives, with the advantage of being a source of silicon, a beneficial element to the grasses. However, high concentrations of silicon in the plant would affect the digestibility of the forage. To evaluate the influence of the substitution of the calcium carbonate by calcium silicate on the nutrition, biomass production and

35. 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,
