Article
Full-text available
The effect of biochar alone or co-applied with triple superphosphate on rhizosphere soil characteristics, nodule formation, phytoconstituents and antioxidant property of cowpea (Vigna uguiculata) is yet to be adequately examined in sub Saharan Africa. A field experiment was conducted where cowpea (Vigna unguiculata) was grown in a tropical sandy lo...
Article
Full-text available
The parasitic weed, Striga gesnerioides, imposes physiological stress on cowpea (Vigna unguiculata (L.) Walp.) resulting in significant yield loss in the regions of northern Ghana. This warranted identification of resistant cowpeas for sustainable production. The current work aim was to identify Striga-resistant cowpea genotypes and assess their ge...

Cowpea rust fungus affects photosynthetic rate and physiological performance of the host plant through the induction of structural changes in the host cell. The study assessed the effects of rust fungus onnet photosynthetic efficiency and yield performance of cowpea genotypes under field conditions. The experiment was conducted in the minor croppin...

Background: Mealybug wilt of pineapple (MWP) is the most destructive viral disease of pineapple worldwide. The disease is caused by pineapple mealybug wilt-associated virus (PMWaV), a member of the family Closteroviridae and the genus Ampelovirus, and transmitted by mealybugs. Methods: In order to understand the association between closteroviruses...

The parasitic plant, Striga gesnerioides (Willd.) Vatke, is one of the most important constraints of cowpea production and food security in West Africa. Currently, few Striga resistant cowpea varieties have been developed that are well‐adapted to the dry savannah regions of Ghana. While genes conferring resistance to Striga races SG1, SG3 and SG5 h...

Cowpea [ In northern Ghana, cowpea is the second most important crop after groundnut and a ch protein in the diet, hence it is critical to improve production of the crop. This study assessed the demography, Multi-stage random sampling technique wa and 21 agriculture extension officers in five cowpea growing districts involving closed and opened end...
Article
Full-text available
Viruses are a major constraint to cowpea production in sub-Saharan Africa. Host plant resistance is the most effective and reliable method of managing viral diseases. In order to identify the source of resistance or tolerance, 38 cowpea genotypes were screened for virus infection under field conditions during the 2016 wet and dry seasons. The exper...

Cowpea [ Vigna unguiculata (L.) Walp] is an important food security crop in Sub-Saharan Africa. However, cowpea production in some parts of this region is constrained by Striga gesnerioides (Willd.) Vatke infestation resulting in yield losses. This study assessed the farmers and agricultural extension officers (AEOs) perception of S. gesnerioides p...

Cultivation of okra in Ghana is challenged by low yield due to lack of improved varieties. Gamma irradiated okra seeds can generate genetic variability to improve the crop. Samples of 150 seeds, each of okra genotype, UCCC6, were irradiated with 400 Gy to 1000 Gy using cobalt 60 source at a dose rate exposure of 121.58 Gy/hr. There were 40 stands c...

A total of 21 okra (Abelmoschus escuentus L. Moench) genotypes were screened for their reactions against okra mosaic disease (OMD) and flea beetles (Podagrica species) infestations in field trials which were conducted from May to October, 2015 (wet season) and November 2015 to March 2016 (dry season), in order to identify sources of resistance and...

Micropropagation is a more rapid means to generate adequate healthy sugar cane planting materials towards increased sustainable production of the crop for industrial processing to produce sugar. However, stable axenic cultures and optimum growth regulators are critical to in vitro propagation of sugar cane. The study was to determine the optimum co...

Tissue culture enhances rapid multiplication of suckers to supplement conventional methods to produce pineapples to meet both local and international demands. However, culture initiation, the most critical step towards rapid multiplication in vitro, is challenged by microbial contamination, exogenous growth hormone requirements and type of explants...
Article
Full-text available
Striga gesnerioides, commonly called witchweed, is a major constraint to growth and productivity of cowpea (Vigna unguiculata L. Walp) throughout West Africa. We have screened the cowpea accessions available in the germplasm collections from Ghana for their reaction to Striga gesnerioides, with the aim of identifying new sources of resistance to th...
Article
Full-text available
Genetic diversity and phylogenetic relationships among 141 cowpea (Vigna unguiculata L. Walp.) accessions collected throughout the nine geographical regions of Ghana were evaluated using simple sequence repeat (SSR) molecular markers. Twenty-five primer combinations pre-selected by their ability to polymerase chain reaction amplify SSRs from a set...
