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.

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‐

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.).

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

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.

Expression of genes from the lignin synthesis pathway in guineagrass genotypes differing in cell‐wall digestibility

Grass and Forage Science, 2011
AbstractRapid decline in cell‐wall digestibility hinders efficient use of warm‐season grasses. The objective of this study was to identify genes whose expressions are related to the slope of decline in cell‐wall digestibility. Eleven guineagrass genotypes were harvested at three ages and classified according to fibre digestibility.

Nitrogen management in mombasa guineagrass as a function of sources and rates of nitrogen

2019
O nitrogênio é o nutriente que mais influencia na produtividade e na qualidade das pastagens. Objetivou-se estudar a condução de uma pastagem com alto potencial produtivo utilizando fontes e doses de nitrogênio (N), visando contribuir para o desenvolvimento da pecuária, quantificando-se a produtividade de matéria seca (PMS), os teores de proteína bruta
