Biology of Sourgrass and Its Competition with Buffelgrass and Guineagrass

Weed Science, 1977
Establishment and early growth characteristics were defined for sourgrass [Trichachne insularis(L.) Nees], one of the most serious pasture weeds in Hawaii. Optimum germination of sourgrass seeds was obtained in the light at 30 C or with alternating temperatures of 20 and 30 C or 25 and 35 C.

Ecotypic differentiation in guineagrass (Panicum maximum Jacq.)

Agro-Ecosystems, 1979
Abstract Six Brazilian populations of guineagrass ( Panicum maximum Jacq.) were studied in order to evaluate their quantitative and allozyme variation and to correlate their ecotypic differences with average monthly temperature and rainfall at the collection sites.

Herbage responses of Tamani and Quênia guineagrasses to grazing intensity

Agronomy Journal, 2020
AbstractNew forage cultivars require defoliation studies for recommending proper grazing management. Our objective was to characterize herbage accumulation (HA), plant‐part composition and nutritive value of guineagrass [Megathyrsus maximus (Jacq.) B. K. Simon & S. W. L. Jacobs] rotationally stocked under two grazing intensities.

Simple agrometeorological models for estimating Guineagrass yield in Southeast Brazil

International Journal of Biometeorology, 2013
The objective of this work was to develop and evaluate agrometeorological models to simulate the production of Guineagrass. For this purpose, we used forage yield from 54 growing periods between December 2004-January 2007 and April 2010-March 2012 in irrigated and non-irrigated pastures in São Carlos, São Paulo state, Brazil (latitude 21°57'42″ S ...

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 ...

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.
