Crop coefficients of tropical forage crops, single cropped and overseeded with black oat and ryegrass

Scientia Agricola
: Crop coefficient (Kc) is the ratio between crop evapotranspiration (ETc) and reference evapotranspiration (ETo), representing the phenological effects on crop water consumption. Kc is fundamental to estimating ETc by agrometeorological methods.

Polycyclic Aromatic Hydrocarbons in Soil and Vegetation of Niger Delta, Nigeria: Ecological Risk Assessment

Journal of Toxicology, 2023
The Niger Delta, Nigeria, is noted for crude oil exploration. Whereas there seems to be a handful of data on soil polycyclic aromatic hydrocarbon (PAH) levels in this area, there is a paucity of studies that have evaluated soil and vegetation PAHs ...

Phytoremediation by Guinea grass (Panicum maximum): A Focused Review

Turkish Journal of Range and Forage Science, 2023
Environmental contamination from heavy metals has grown to be a significant problem on a global basis. Due to the mobilisation of heavy metals during ore extraction and subsequent processing for diverse applications, they have been dispersed into the environment.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES [PDF]

Engenharia Agrícola, 2019
One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated.

A role for epithelium‐derived 6‐nitrodopamine on human ureter contractility

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose To investigate the basal release of 6‐nitrodopamine (6‐ND) from human isolated ureter and the role of this novel catecholamine in the ureter contractility. Experimental Approach Ureters from 67 brain‐dead organ donors (40 males and 27 females) were used during kidney transplantation procedures.

Recent Replacement of Native Pili Grass (Heteropogon contortus) by Invasive African Grasses in the Hawaiian Islands [PDF]

, 1998
We surveyed 41 sites from throughout O'ahu that had been dominated by native pili grass (Heteropogon contortus) in the late 1960s. Pili grass was absent from 14 (35%) of those sites in 1997 and had declined in abundance in most of the 27 remaining ...

Introduced mona monkey Cercopithecus mona is a key predator of bird nests in the endemic‐rich Príncipe Island

Conservation Science and Practice, EarlyView.
Abstract Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal species.

Preference and In Vitro Digestibility of Leaves of Woody Plants by Sheep in the Northern Sudanian Zone

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT In West Africa, trees and shrubs are important for feeding ruminant livestock during the dry season. This study aimed to determine the in vitro digestibility of organic matter from eight woody species using a gas test with and without the addition of polyethylene glycol (PEG), and evaluate their preference by sheep using a cafeteria test ...

Influence of supplementing Guinea grass with differently processed African yam bean on gas production and in vitro digestibility

Revista Brasileira de Zootecnia, 2020
This study evaluated the potential utilisation of African yam bean (AYB) seed as a supplement to Guinea grass on in vitro gas and methane (CH4) production, as well as the effect of processing on AYB nutritive value.
