Herbage accumulation and tillering dynamics of ‘Zuri’ guineagrass under rotational stocking

Crop Science, 2021
AbstractUnderstanding the effects of grazing management on tillering dynamics of forage grasses may help identify management practices that optimize pasture production, stability, and ultimately, persistence. The objective of this research was to evaluate the effects of two grazing frequencies (regrowth interrupted when the canopy was 70 cm tall or at ...

Urea ammoniation effects on the feeding value of guineagrass (Panicum maximum) hay.

Journal of Animal Science, 1995
Laboratory, digestion, and growth studies evaluated urea as a source of ammoniation for quality improvement in guineagrass (Panicum maximum) hay. In a laboratory trial, 5.0-kg portions of hay were reconstituted with water to yield final forage moisture concentrations or 25 of 40% and treated with urea at 0, 4, 6, or 8% of the forage DM, with or without

YIELD PERFORMANCE OF GUINEAGRASS HYBRIDS UNDER CUTTING MANAGEMENT

1997
Developing hybrids of guineagrass (Panicum maximum Jacq.) is difficult mainly because its reproduction is by apomixis. Utilizing sexual female plants and facultative apomictic genotypes, the following crosses were developed at the USDA-ARS, Tropical Agriculture Research Station (TARS): GH-101 (Tift SPM 92 χ PI 3622); GH-102 (Tift 49 χ CI AT 604); GH ...

Seasonal Liveweight Gain of Beef Cattle on Guineagrass Pastures in the Brazilian Cerrados

Agronomy Journal, 2018
Core Ideas The cultivars Tamani and Zuri have greater nutritive value than cultivar Massai.The individual cattle performance was greater in Tamani and Zuri pastures.Massai provided the same liveweight gain per area than Tamani and Zuri.Tamani and Zuri can be used in grazing systems aiming cattle growing and fattening.Tamani can minimize usual ...

Response of Guineagrass to Aquaculture Effluent Irrigation During the Dry Season

1999
This paper will present the results of a nitrogen and sulfur fertilizer trial on bahiagrass (Paspalum notatum). Treatments consisted of two forms of nitrogen (ammonium nitrate and ammonium sulfate), three rates of nitrogen (0, 75, and 150 kg N/ha/yr) and three rates of sulfur (0, 86,174 kg S/ha/yr) applied to an established stand of bahiagrass grown on

Anatomical Basis for Seed Shattering in Kleingrass and Guineagrass¹

Crop Science, 1983
Anatomical studies of abscission layer development in kleingrass (Panicum coloratum L.) and guineagrass (P. maximum Jacq.) were conducted to determine the sequential histogenesis of the abscission layers which lead to seed shattering and to relate layer development to identifiable morphological stages of developing inflorescences.

Spikelet Abscission in Guineagrass as Influenced by Auxin and Gibberellin¹

Crop Science, 1979
Seed production of guineagrass (Panicum maximum Jacq.), an important pasture and forage crop in the tropics, is hindered by its heavy loss of seeds through spikelet abscission. A method whereby abscission could be delayed or arrested would be a great aid in seed harvest of this and other Panicum species.Auxin and gibberellin at three concentrations (10‐

Improving the CROPGRO Perennial Forage Model for simulating growth and biomass partitioning of guineagrass

Agronomy Journal, 2021
AbstractTropical forage grasses are used for several applications including grazing, silage, and biofuels; with harvesting at varying phenological stages. Mechanistic simulation models can be powerful tools to assist with planning and decision making of pasture utilization strategies.

Potassium fertilization and defoliation intensity effects on forage characteristics of “BRS Zuri” guineagrass

Grassland Science
AbstractThe objective of this study was to evaluate the effects of different potassium (K) fertilization levels and defoliation intensities on performance of “BRS Zuri” guineagrass Megathyrsus maximus (Jacq.) B.K. Simon & S.W.L Jacobs (syn. Panicum maximum Jacq.). Treatments were the factorial arrangement of three K fertilization levels: 0 (control)

Intercropping Time of Corn and Palisadegrass or Guineagrass Affecting Grain Yield and Forage Production

Crop Science, 2013
