Growth, Nodulation, and Yield Responses of Groundnut (Arachis hypogaea L.) as Influenced by Combined Application of Rhizobium Inoculant and Phosphorus in the Guinea Savanna Zone of Ghana

International Journal of Agronomy, 2020
Groundnut yields obtained by farmers in northern Ghana are generally low due to low soil fertility resulting from continuous cropping coupled with low use of external inputs.

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

The Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Improved storage technique and management of aflatoxin in peanut production: Evidence from Northern Ghana

Scientific African, 2020
Peanut production contributes to food security in northern Ghana due to its ability to tolerate drought and survive on marginal lands. This notwithstanding, poor handling along the value chain favors aflatoxin contamination, a threat to human and animal ...

Pelvic breadth and juvenile locomotor energetics: Implications for the obstetrical dilemma hypothesis across human growth in past and present humans

The Anatomical Record, EarlyView.
Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Biochar effects on soil properties and yield of maize in Northern region, Ghana

Discover Agriculture
Soil degradation and declining crop productivity are persistent challenges in global agriculture, particularly in sub-Saharan Africa. While biochar application has gained recognition as a sustainable soil amendment, this study systematically evaluates ...

Soil Amendments and Rotation Effects on Soybean and Maize Growths and Soil Chemical Changes in Northern Ghana

International Journal of Agronomy, 2017
A four-year field trial was conducted at Bonia in the Upper East Region of Ghana to evaluate soybean-maize rotation amendment systems. The treatments included soybean without amendment, inoculated soybean, inoculated soybean with fertisol, inoculated ...
