ABSTRACT Striga hermollthica (De.) Benth. infest millions of hectares of land under cereals in sub-Saharan Africa, threatening food security. One of the major crops threatened i~ maize (Zea mays L.), a staple food for many Ghanaians. The objectives of this study were to investigate the combining ability and heritability of Striga-resistant maize inbred lines for the selection ofsuperior lines for hybridization. A diallel cross involving ten (10) maize inbred lines was made to produce forty-f...
ABSTRACT A dry rot of yam Dioscorea rotundata which attacks tubers in the field and in storage is currently threatening production of the crop in the Krachi Nchumuru District of the Volta Region No detailed investigation has been conducted therefore a study was carried out from October 2016 to May 2017 to assess the knowledge, perception and experiences of farmers in the District on the occurrence and management of the tuber dry rot disease, isolate, identify and assess plant parasitic nemato...
ABSTRACT Field experiments were conducted in 2016 and 2017 cropping seasons at the University of Education Winneba, Faculty of Agriculture Education, Mampong in the forest-savannah transitional zone of Ghana. The study was to evaluate the growth and yield response of two onion varieties to integrated nutrient management in the transional zone of Ghana. The treatments used were 10 t/ha Cow Dung, 10 t/ha Poultry Manure, 300 Kg/ha NPK, combination of half rate animal manure and half rate ...

ABSTRACT Two field experiments were conducted at the Multipurpose Crop Nursery of the University of Education, Winneba, Mampong – Ashanti during the 2015 and 2016 cropping seasons from August to November, 2015 and June to September, 2016 respectively. The objective of the study was to determine the organic and inorganic fertilizer effects on the growth and yield of cabbage (Brassica oleraceae var capitata), and incidence of pest in the forest transition agro – ecological zone of ...
ABSTRACT The research was carried out in two locations namely: Soil Research Institute, Kwadaso and Wenchi Agri. Research Institute, Wenchi. The experiment was laid out in randomized complete block design (RCBD) with three replications. Treatments in the first and second trials consisted of two factors: three levels of fertilizer (0-15-30 N-P2O5-K2O kg ha-1,), and four cassava based cropping systems. The behaviour of component crops in three row arrangements was evaluated in the third trial...
ABSTRACT The genetic diversity in 100 cassava accessions collected from eight regions of Ghana was assessed using morphological and molecular characterisation. Both qualitative and quantitative morphological traits were used to assess variability in the accessions. Canonical discriminant analysis of morphological data showed that quantitative traits detected more variability than qualitative traits. A set of 1 0 random sequence 1 0 mer oligonucleotide primers selected from among eighty th...
ABSTRACT Cowpea (Vigna unguiculata (L) Walp) is an economically important legume crop of vital importance to the livelihood of several millions of people. Even so, cowpea yields on African farmers’ fields are still below the potential yield of the crop. This is, largely, as a result of the use of unimproved genotypes and farming on phosphorus (P)-poor soils, which are pervasive in the tropics. Plants have evolved several strategies to obtain adequate P for their growth under P limiting con...
ABSTRACT Integrated Nutrient Management with biochar and inorganic fertilizer is critical to sustainable agriculture including the enhancement of production systems for climate change mitigation and adaptation. The objective of this research was to evaluate how soil management could be improved to respond to increasing environmental pressure on soil and crop in carrot production and to examine how anthropogenic changes in and management of soil affect crop growth, yield and nutritional...
ABSTRACT The phenological development, growth, yield and yield stability performance of eight cowpea varieties released in Ghana between 1990 and 2015 were evaluated in field experiments carried out at Mampong-Ashanti (forest-savannah transition zone) and Fumesua (forest zone) over two cropping seasons in 2015 and 2016. The experiments were arranged in a randomized complete block design (RCBD) with three replicates. Asontem, Nhyira, Asetenapa, Hewale and Videza flowered and podded earl...
ABSTRACT Cowpea, Vigna unguiculata, is an important human and livestock protein source in Nigeria, but its production is constrained by ravages of pests and climate change. Conventional breeding efforts used to fortify it against these constraints had resulted into its narrow genetic base. In order to overcome this challenge, other mutation procedures such as physical and chemical mutagens could be used. Nevertheless, information on gamma and ultra-violet (UV) irradiated cowpea seeds and pol...
ABSTRACT Tomato yellow leaf curl viral disease (TYLCV) is a destructive disease of tomato in Ghana. The study was conducted during the 2013 minor and 2014 major cropping seasons to determine the knowledge of farmers and their agronomic practices they carry out to manage TYLCV disease in three districts in the Central region, screening of thirty six tomato genotypes against TYLCV disease for a possible tolerant variety and phenotypic and molecular evaluation of selected tolerant genotypes at ...
ABSTRACT The study shows Aspergillus flavus and aflatoxin contamination of groundnut (Arachis hypogaea L) from groundnut samples collected from the six markets in the Central Region of Ghana namely: Swedru, Mankessim, Cape Coast, Fosu, Jukwa and Kasoa. All groundnut sellers interviewed were females and have no knowledge about aflatoxins. Thirty five percent 35% of the groundnut sellers had no formal education whilst 26.7% had basic primary education and 23.3% had Junior high school educatio...
ABSTRACT Maize streak disease (MSD) is the most important viral disease affecting maize production in Ghana. Management options employed to mitigate the effect of the disease has not been successful. Breeding for disease resistant is the most sustainable option. Mutation breeding was used in this study to develop maize mutants’ lines that are resistant MSD. Radiosensitivity was first carried out to determine the optimum dose for mutation induction in six cultivars of maize grown in the stu...
ABSTRACT The study was carried out to assess the influence of Colletotrichum dematium one of the major causes of pepper diseases on the declining yield of pepper in the Ajumako Enyan Essiam district of the Central Region and to find the extent of transmission through different inoculation methods. Three fruit types (riped, unriped and dropped) were collected from six farms across four locations (Akuamase, Nkodwo, Esikado and Mando) and another sample which was made up of only riped fruits was...
