Restoration of Florida scrub vegetation in an old field through 23 years after planting

Restoration Ecology, Volume 27, Issue 2, Page 320-332, March 2019., 2019
Florida scrub, a fire‐maintained, xeromorphic shrubland, hosts many rare and declining species, but most scrub habitat has been lost to development and agriculture. Formerly cultivated sites offer an opportunity to restore Florida scrub. In this 23‐year study, we test whether scrub species could be restored to an old field and whether scrub vegetation ...

Effect of Nitrogen Fertilization on Oxalate Content in Rhodesgrass, Guineagrass and Sudangrass

Asian-Australasian Journal of Animal Sciences, 2008
An experiment was conducted to evaluate the effects of nitrogen (N) level on the dry matter (DM) yield, N concentration and oxalate content of some tropical grasses, namely Rhodesgrass (Chloris gayana), Guineagrass (Panicum maximum) and Sudangrass (Sorghum vulgare).

Ammonium sulfate enhances the effectiveness of reactive natural phosphate for fertilizing tropical grasses

Tropical Grasslands-Forrajes Tropicales, 2020
Reactive natural phosphate is a slow and gradual solubilizing fertilizer, which makes it difficult to use in neutral to alkaline soils. Nitrogen fertilizers which acidify the soil may increase the possibility of using this phosphate fertilizer ...

Biologically Fixed Nitrogen in Legume Intercropped Systems: Comparison of Nitrogen‐Difference and Nitrogen‐15 Enrichment Techniques

Agronomy Journal, Volume 107, Issue 6, Page 2419-2430, November–December 2015., 2015
Biological N2 fixation (BNF) via legume intercrops can provide an alternative to inorganic N fertilizer and thereby minimize the economic and environmental costs of bioenergy feedstock and forage production. The objectives of this study were to (i) verify switchgrass (Panicum virgatum L.) as a non‐N2–fixing reference plant for distinguishing between ...

Effects of nitrogen fertilizer rate on dry matter yield, nutritive values and nitrate nitrogen of Guineagrass (Panicum maximum Jacq.) extremely late cultivar “Umaku” as a summer annual grass in a warm temperate zone

Grassland Science, Volume 72, Issue 2, Page 151-160, April 2026.
Abstract Cultivation as a summer annual grass in temperate regions of new extremely late‐maturing guineagrass cultivar “Umaku” without heading with fertilizer application entails risks of toxic nitrate nitrogen (nitrate‐N) concentration in the grass.

Genetic Diversity and Structure of Ruzigrass Germplasm Collected in Africa and Brazil

Crop Science, Volume 55, Issue 6, Page 2736-2745, November-December 2015., 2015
ABSTRACT Ruzigrass [Urochloa ruziziensis (R. Germain & Evrard) Crins, syn. Brachiaria ruziziensis Germain & Evrard] is a tropical forage native to Africa, first introduced in Brazil in the 1960s. Ruzigrass is diploid, presents sexual reproduction, and is a model species for the generation of genomic resources in the Brachiaria genus. Brachiaria species
