ABSTRACT Field trials were conducted in 2012 and 2013 cropping seasons on a naturally heavily striga infested field at the research farm of Federal University of Technology, Gidan kwano campus Minna to evaluate the effect of seed treatment, sowing date and trap crop in the management of Striga hermonthica. The experiment consisted of two varieties of sorghum (resistant ICSV1002 and susceptible Gwari local varieties), three different concentration of Parkia pulp powder (0, 66 and 100 g/l) and ...
ABSTRACT Plukenetia conophorum Muell Arg commonly called African walnut is cultivated principally for the nuts which are cooked and consumed as snacks. The plant serves many nutritional and medicinal purposes yet its availability is on the decline. To preserve and ensure continued availability of P. conophorum, there is the need to develop propagation protocols for the plant. Five accessions were collected from Mbu, Nsukka, Orba and two locations in Edem-ani all in Enugu State, Southeastern, ...
ABSTRACT Field, greenhouse and laboratory studies were carried out at the Department of Crop Science, University of Nigeria, Nsukka in order to evaluate the leaf spot disease of eggplant and its management with some botanicals. Field survey of diseased plants was conducted on eggplant farm. Solanum aethiopicum L. plants were sampled on every 1 m distance along the diagonal transects for disease incidence and severity. Pathogen isolation from severely infected leaves was carried out in the lab...
ABSTRACT Promiscuous (naturally nodulating) IITA (International Institute of Tropical Agriculture) soybean (Glycine max (L) Merrill) varieties and elite varieties of maize (Zea mays L.) were evaluated in four experiments between 2007 and 2009, for their growth and yield responses to an area without history of soybean cultivation, some soil fertility management options and for soybean fertilizer replacement value (FRV) to companion and subsequent non-legume maize crop. These experiments were c...
ABSTRACT Cassava mosaic disease caused by begomoviruses is the most widespread disease of cassava in Africa. Simple sequence repeat (SSR) genetic analysis of an F1 population of cassava was carried out to identify new sources of CMD resistance. Genomic DNA extracted from parents and progeny was amplified using polymerase chain reaction (PCR). PCR amplifications were run on polyacrylamide and agarose gels. SSR marker technology was used to identify markers linked to CMD resistance via bulk seg...
ABSTRACT Studies were carried out at the Department of Crop science, University of Nigeria Nsukka (UNN) to evaluate botanicals control of diseases associated with growth and germination of Moringa seeds. Five accessions of Moringa seeds collected from Imo, Enugu, Kogi, Plateau and Kaduna states of Nigeria were used. The following experiments were carried out: seed viability test, isolation of fungal pathogens, determination of phytochemicals, in vitro control of the pathogens with six botanic...
ABSTRACT Mouldiness in stored cocoa beans in Ghana and the production of aflatoxin have been studied. Based on actual weight of discarded beans, mouldy beans have been estimated to constitute 0.13 % and 0.00002 % of marketable beans at the farm ers’ level and the buying agents’ depots respectively in the Tafo District. This is contrasted with an estimated value o f 0.16 % obtained in a questionnaire type study involving farmers. Estimated mouldy beans at the Tema port was 0.69 % per year...
ABSTRACT Pigeon pea plays a significant role in smallholder farmers‟ subsistence. In Benin, there is a dearth of information on the genetic diversity present in the crop. Indigenous knowledge used in folk medicines, taxonomy, crop management and seed system have not been assembled and documented. This study aimed at assessing farmers‟ knowledge related to pigeon pea cultivation and uses and genetic diversity of pigeon pea germplasm in Benin. Participatory Rural Appraisal including indivi...
ABSTRACT A study was conducted to determine the effects of different growth media and different poly bag sizes on the growth of cocoa seedlings in the nursery. The experimental design was split plot design with three replicates. The treatments were soil (S), carbonated rice husk (CRH), cocoa pod husk (CPH), cocopeat (CP) , sawdust (SD), S+CRH, S+CPH, S+CP, S+SD, CRH+CPH, CRH+CP, CRH+SD, CPH+CP, CPH+SD, CP+SD and the three polytene bag sizes were 12.5 cm x 18.5 cm (small), 10.0 cm x 35.0 cm ...
ABSTRACT In order to determine genetic variability in some accessions of Africa eggplant, open field experiments were conducted in two separate locations, one at University of Ghana farm, Legon and the other at the Forest and Horticultural Crops Research Centre (FOHCREC), OkumaningKade simultaneously. The experimental design used was the Randomized Complete Block Design (RCBD) with three (3) replications. The combined analysis of variance was carried out for the data gathered. The effect of...
Early sprouting of yam tuber is a typical problem during storage resulting into weight losses, deterioration, shrinkage and reduction in quality. This research work therefore carried out investigation on the application of vibration technique for the control of physical properties of yam (Dioscorea spp.) sprouts during storage in FUNAAB, Nigeria environment. The physical properties (length, number and weight of sprout, number of leaves and weight of roots) of the yam sprouts were determi...
ABSTRACT The pathogenicity of fungus, Fusarium oxysporum f. sp. lycopersici and nematode, Meloidogyne incognita on growth, yield and wilt severity was studied on two tomato varieties, Mongal F1 and Petomech in a randomized complete block design, factorial experiment with three replications on the University of Ghana and National service farms from July 2018 to June 2019. Each plot had an area of 10 m2 with 25 plants. Fusarium inoculum of 1.3×106 cells per 5 mL was inoculated on fields natur...
ABSTRACT Amaranth is one of the African indigenous vegetables that is gaining popularity due to its nutritional, medicinal and economic values. Its potential as a source of food security in East Africa and most parts of the world has heightened demands for the once neglected crop. In Kenya and Tanzania, the Lepidopteran defoliators are important pests of the crop which can cause up to 100% yield loss. Little information on the population dynamics of these pests make their management difficul...
ABSTRACT Green (fresh) maize (Zea mays L.) provides food security and income to farmers especially when other crops are still in the field. However, research on green maize variety is scarcely reported in literature or information on suitable genetic material (germplasm) for green maize production. Developing maize for fresh maize production in the southeastern Nigeria was carried out in the Center for Agricultural Research, School of Agriculture and Agricultural Technology, Federal Universi...
ABSTRACT The parasitic weed Striga hermonthica (Del.) Benth. of the Scrophulariaceae family constitutes one of the most economically important biological constraints in maize production in the sub-Saharan regions of Africa. The type of gene action involved in the inheritance of resistance to Striga hermonthica was investigated using the open-pollinated population, TZLComposite-1 Cl in a North Carolina design 1 scheme. Recombination were done among the best families and also the poorest perfo...
