A study was carried out on the incidence, isolation and identification of fungal pathogens of the leaves of cultivated white yam, Dioscorea rotundata Poir and water yam, Dioscorea alata Lam found on four farmers’ fields between August and October 2010. Farm locations used included those in Tse-Ugba, Tor-Donga, Abaji-Kpav and Katsina-Ala in Katsina-Ala Local Government Area of Benue State of Nigeria. Diseased leaves and vine samples were randomly collected from some fields during the study. ...
Studies were carried out on biological control using dual culture method to assess the potential of Trichoderma harzianum against Fusarium oxysporum, the causal agent of tuber dry rot disease of white yam in vitro. The rot-causing fungal organism was isolated from rotted yam tubers collected from different storage barns in Zaki-Biam, Benue State of Nigeria. The biological agent (T. harzianum) was introduced at three different times (same time with the pathogen, 2 days before the inoculation o...
Studies were carried out on the effect of some hot aqueous plant extracts using Piper guineense, Zingiber officinale, Azadiracta indica, Carica papaya and Nicotiana tabacum using three concentrations (30, 60 and 90g/l) along with a chemical fungicide (mancozeb) at three concentrations (4, 8 and 12g/l) amended in potato dextrose agar (PDA) on in vitro control of B. theobromae, causal organism of yam tuber rot. The research was conducted at Advanced Plant Pathology Laboratory, Federal Universit...
Studies were carried out on the in-vitro evaluation of plant extracts in the control of some fungal pathogens from tomatoes (Solanum lycopersicum L) fruits collected from Darawa, Dutsin-Ma and Makera settlements in Dutsin-Ma Local Government Area of Katsina State, Nigeria using neem (Azadirachta indica) and ginger (Zingiber officinale) extracts. Rotted tomato fruits were collected from same locations and taken to Biological science laboratory for isolation, identification and subsequently ...
Efficacy of some plant extracts (Piper nigrum, Zingiber officinale, Azadirachta indica, Carica papya and Nicotiana tabacum) and a chemical fungicide (mancozeb) using three concentrations of hot aqueous plant extracts (30, 60 and 90 g/l) and mancozeb (4, 8 and 12 g/l) in in vitro inhibition of Colletotrichum sp. mycelia was carried out at Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. Rotted yam tubers were collected from farmers’ barns and take...
Studies were conducted in vitro to determine the antagonistic potential of Trichoderma harzianum for biological control of Fusarium moniliforme isolated from rotted Dioscorea rotundata tubers. The experiments were performed at Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. Fungi organisms isolated and identified from the rotted white yam tubers were Botryodiploidia theobromae, Aspergillus flavus, Aspergillus niger, Aspergillus ochraceus, Fusarium...
Nine fungal organisms were isolated from rotted white yam (Dioscorea rotundata) tubers from Kadarko, Nasarawa, Nigeria between February and May, 2015. Trichoderma harzianum was used as a biological agent to evaluate its potential against Colletotrichum species isolated from rotted white yam tubers in dual culture method at Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. Percentage frequency of occurrence of the isolated fungal organisms was determined...
Studies on the antimicrobial potency was carried out on five crude plant extracts (Piper nigrum, Zingiber officinale, Azadirachta indica, Carica papya and Nicotiana tabacum) and a chemical fungicide (mancozeb) using three concentrations of hot aqueous plant extracts (30, 60 and 90 g/l) and mancozeb (4, 8 and 12 g/l). The extracts and chemical were separately amended in potato dextrose agar (PDA) in in vitro control of Aspergillus flavus; causal agent of yam tuber rot. Rotten white yam...
In vitro assessment of biological control of Trichoderma harzianum against Penicillium purpurogenum isolated from rotted yam tubers (Dioscorea rotundata Poir) in storage was conducted in the Advanced Plant Pathology Laboratory, Federal University of Agriculture, Makurdi, Nigeria. The antagonist and the pathogen were paired in dual culture at different times (antagonist same time with the pathogen, 2 days before the inoculation of the pathogen and 2 days after the inoculation of the pathog...
ABSTRACT The study examines the determinants of agricultural output based on the empirical evidence of the short-run and long-run interrelationships among capital expenditure on agriculture, inflation rate, external reserve, interest rate, average annual rainfall and food importation using agricultural output as dependent variable. Macroeconomics data from 1970 – 2012 were sourced from Central Bank Statistical Bulletin and National Bureau of Statistics publications of several years. Data we...
Abstract: Despite increasing interest in income polarisation among researchers in Nigeria, there is dearth of literature on its existence among undergraduate students especially with the primary data. A polarised income distribution among students has the potential of breeding social unrest, protest or demonstration. This study examined the existence of income polarization and inequality among ...
Crops are faced with several definite environmental stresses either concurrently or at different periods during their entire growth and productivity season. Combinational occurrence of stresses and pollution such as salinity stress and crude oil pollution is destructive to crop growth and productivity than these stresses occurring separately at different crop growth. This research was aimed at showing different stress combinations (salinity stress and crude oil pollution) and their impact on ...

ABSTRACT This research work was analysed the cost and returns of poultry egg production in Odeda Local Government Area of Ogun State. Primary data was collected from 90 poultry egg farmers drawn from the study area by a simple random sampling technique. The data collected were analysed using descriptive, budgetary, regression analysis and likert scale. The socio-economic characteristics of the farmers were determined using descriptive method to find out their various frequencies like in ...
