1. CARACTERÍSTICAS ESTRUTURAIS E PRODUTIVAS EM HÍBRIDOS INTRAESPECÍFICOS E INTERESPECÍFICOS DE CAPIM-ELEFANTE
Resumo Objetivou-se avaliar a estrutura e a produção de forragem em híbridos de capim-elefante manejados sob corte. Utilizaram-se como tratamentos 24 clones de capim-elefante provenientes da Embrapa Gado de Leite e o Cameroom como testemunha. Os capins foram cortados rentes ao solo, a cada 60 dias. Os parâmetros avaliados foram: produção e teor de mat�

3. Morphological and structural characteristics of Urochloa decumbens Stapf. deferred pasture grazed by heifers under two periods of protein-energy supplementation
ABSTRACT. The aim of this study was to evaluate the morphological and structural characteristics of deferred Urochloa decumbens Stapf. ‘Basilisk’ grazed by Nellore heifers under two periods of protein and energy supplementation (PES). The experiment was carried out from Jun 21 to Nov 15, 2016, under a completely randomized design and two PES periods (55

4. Structural characteristics and forage mass of Tifton 85 pastures managed under three post-grazing residual leaf areas
The experiment was carried out on Cynodon spp cv. Tifton 85 pastures grazed by sheep under rotational stocking, with the objective of evaluating the structural characteristics as well as the forage mass of the pastures subjected to three grazing intensities in successive cycles. Treatments were composed of three residual leaf area indices (rLAI; 2.4; 1.6 and

5. Características estruturais de gramíneas e desempenho animal em pastagens sob lotação intermitente e adubação nitrogenada no agreste semiárido de Pernambuco. / Structural characteristics of grasses and animal performance on pasture under rotational stocking and fertilization in semiarid region of Pernambuco agreste.
No Agreste de Pernambuco, apesar de muitas espécies forrageiras serem utilizadas na formação das pastagens, tais como o capim-pangolão (Digitaria pentzi Stent.), capim-corrente [Urochloa mosambicensis (Hackel) Dandy] e o capim-de-raiz (Chloris orthonoton Doell), há carência de estudos sobre as respostas no crescimento e produtivas destas plantas quando

6. 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

7. Adaptation of the C4 grass Panicum maximum to defoliation is related to plasticity of N uptake, mobilisation and allocation patterns
Dry mass production and persistence of Panicum maximum pastures depends on nitrogen supply. Defoliation influences N uptake and allocation patterns yet its effects on plasticity of N dynamics in P. maximum have not been investigated. Stable isotopes of N (15N) were used in order to test the hypothesis that defoliation in terms of proportion of the leaf area

8. Forage mass and structure of piatã grass deferred at different heights and variable periods
The objective of this study was to determine the deferment period and the most adequate initial sward height of Brachiaria brizantha cv. Piatã for deferment in the region of Viçosa, Minas Gerais. For so, the following characteristics were evaluated: masses and bulk density of forage and its morphological components, light interception by the sward, leaf ar

9. Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure
The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels. Two levels of nitrogen (75 and 150 kg/ha) and one control without fertilization associated to three initi

10. Frequencies and intensities of defoliation in Aruana Guineagrass swards: accumulation and morphological composition of forage
The objective of this study was to assess the accumulation and morphological composition of forage in Aruana Guineagrass (Panicum maximum cv. Aruana) swards subjected to intermittent stocking with sheep. Experimental treatments when grazing was introduced included low (95%) and high (98%) incident light interception and low (10 cm)- and high (15 cm)-residue

11. Effect of irrigation water salinity and cutting age on the components of biomass of Echinochloa pyramidalis
The objective was to evaluate the effect of salinity of irrigation water and different cutting ages on the biomass components of Echinochloa pyramidalis. Seedlings were planted in plastic pots (volume of 8 L) with sandy-textured Quartzarenic Neosol, under greenhouse conditions. The design was completely randomized in split plots with salinity levels (0.75, 2

12. Fontes de fósforo na produção e composição bromatológica de cultivares de milheto forrageiro / Phosphorus sources in production and chemical composition of the peral millet forage
The dry matter yield and quality aspects of forage millet are still poorly understood, as well as specific information handled by this grass and nitrogen fertilization. Experiment was conducted to evaluate the productive potential and chemical composition of the dry mass of three cultivars of pearl millet (Pennisetum glaucum (L.) R. Brown) (ADR-7010, ADR- 50
