Determining the optimal inoculant rate to maximize soybean productivity in the Guinea Savanna agro-ecological zone of Ghana [PDF]

Scientific Reports
Soybean productivity in sub-Saharan Africa is often constrained by low soil fertility and limited biological nitrogen fixation (BNF). This study evaluated the effects of different rhizobial inoculant rates (0, 5, 7.5, 10, and 12.5 g kg−1 seed) on growth,

Integrating biochar, compost, and chemical fertilizer improves maize yield and soil health in the guinea savannah: evidence from two cropping seasons in Northern Ghana [PDF]

Scientific Reports
Maize production by smallholder farmers in sub-Saharan Africa is constrained by declining soil fertility due to low input use and poor nutrient management.

Pleistocene Hypothesis – Moving Savanna Perceptual Preference Hypothesis Beyond Savanna [PDF]

Frontiers in Psychology, 2022
We provide an extension of the Savanna perceptual preference hypothesis (“Savanna Hypothesis”), supposing that interaction with landscapes offering survival advantage for human groups during evolution might have gradually evolved to permanent landscape preferences.

Effects of insecticides and cultivars on panicle-feeding insect pest infestations and grain yield of sorghum (Sorghum bicolor (L.) Moench) in northern Ghana

Bulletin of the National Research Centre, 2021
Background Panicle-feeding insects are a challenge in sorghum (Sorghum bicolor (L.) Moench) cultivation but most farmers do not protect the crop. Here, the effects of pest management in different sorghum cultivars on grain yields and the financial ...

Assessment of the optimal frequency of insecticide sprays required to manage fall armyworm (Spodoptera frugiperda J.E Smith) in maize (Zea mays L.) in northern Ghana

CABI Agriculture and Bioscience, 2022
Background Insecticide use is an important component of integrated pest management strategies developed for fall armyworm (FAW), Spodoptera frugiperda J.E Smith, control in maize in many African countries.

Field efficacy of genetically modified FK 95 Bollgard II cotton for control of bollworms, Lepidoptera, in Ghana

Agriculture & Food Security, 2018
Background Cotton (Gossypium hirsutum L.) cultivation in Ghana is constrained by bollworms that damage squares (flower buds) and developing bolls, resulting in loss in seed cotton yield.

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...
