Multivariate and multiharvesting trial for agronomic traits in the genetic resources of guineagrass
Agronomy Journal, 2022AbstractThe diversity and use of forages and grasslands for animal feeding are essential in tropical livestock systems. Seasonal changes are mainly marked by variations in precipitation patterns. Grasslands are managed as perennial crops and therefore must be resilient to tolerate both dry and rainy seasons.

Water Stress and Clipping Management Effects on Guineagrass: II. Photosynthesis and Water Relations
Agronomy Journal, 1995AbstractGrowth and biomass production and allocation in guineagrass are affected by clipping and water stress, but little is known about the mechanisms responsible. This study was undertaken to determine the short‐term interacting effects of clipping management and water stress on photosynthesis and water relations of guineagrass (Panicum maximum Jacq.)

Urea ammoniation effects on the feeding value of guineagrass (Panicum maximum) hay.
Journal of Animal Science, 1995Laboratory, 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

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)

Biology of Sourgrass and Its Competition with Buffelgrass and Guineagrass
Weed Science, 1977Establishment 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, 1979Abstract 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, 2020AbstractNew 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, 2013The 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 ...
