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 ...

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 ...

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 ...

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.

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.

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

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‐

Norflurazon Selectivity in Two Biotypes of Guineagrass (Panicum maximum)

Weed Science, 1987
Phytotoxicity, absorption, translocation, and metabolism of root-applied norflurazon [4-chloro-5-(methylamino)-2-(3-(trifluoromethyl)phenyl)-3(2H)-pyridazinone] in tolerant narrowleaf and susceptible broadleaf guineagrass (Panicum maximumJacq. # PANMA) biotypes were examined under greenhouse and laboratory conditions. Dose response studies conducted in

Water Stress and Clipping Management Effects on Guineagrass: I. Growth and Biomass Allocation

Agronomy Journal, 1995
AbstractGrowth and biomass allocation of grasses depend greatly on their management and water status. This study was conducted to determine the short‐term interacting effects of clipping height and frequency with water stress on growth and biomass allocation of guineagrass (Panicum maximum Jacq.).

Some Effects of Foliar Applications of Maleic Hydrazide on Guineagrass¹

Agronomy Journal, 1956
SynopsisFour pounds per acre of maleic hydrazide stopped growth of 40‐day old Guineagrass for about 20 days immediately following the spray application. After 20 days, the grass resumed its normal growth rate. When grass was cut a few days after spraying, growth was greatly curtailed for at least 60 days.
