Long and Short Run Dynamics of Agricultural and Petroleum Sectors in the Economic Growth of Nigeria

This study examined the economic relationship among agriculture and petroleum sectors and growth of Nigeria’s economy as well as the effects of these two key sectors on the economic growth. The Bound (ARDL) test which was used to examine the long-run relationship among the variables revealed that there is a long-run relationship among agricultural and petroleum sectors and economic growth. In the short run, both sectors have positive significant relationship with the economic grow...

LONG AND SHORT RUN DYNAMICS OF INSTITUTIONAL CREDIT AND PRODUCTIVITY IN AGRICULTURAL SECTOR: EVIDENCE FROM NIGERIA

This study examined the economic relationship between agricultural productivity and institutional agricultural credit in Nigeria. The two institutionalized credit sources are the commercial bank loans which were proxy as the private sector credit and the government owned Agricultural Credit Guarantee Scheme (ACGS) proxy as the public sector credit while the  agriculture’s contribution to GDP was proxy as agricultural productivity. To estimate these dynamics, three different ARDL  mode...

CAPITAL INVESTMENT: LUBRICANT OF THE ENGINE OF PRODUCTION PROCESS IN AGRICULTURAL SECTOR – EVIDENCE FROM NIGERIA

This study examined the effect of capital investment on the productivity of agricultural sphere of Nigeria. The productivity of the sector was proxy as the agriculture’s contribution to the GDP while commercial bank loan to agriculture, annual budgetary allocation to agricultural sector and various categories of ACGS loan scheme were proxy as investment frameworks. The data used for  thus study were extracted from various bulletin of Central Bank of Nigeria and National Bureau of Sta...

Causes of child labour in crop production in Ondo State, Nigeria

Abstract: This study analyse the causes of child labour in crop production in Akoko South East Local Government Area, Ondo Nigeria. Specifically, it ascertained the socio-economic characteristics of the farmers, ascertained major crop production actives children engages and how often they are involved and reasons for engaging children in crop production was analyzed.A multi-stage technique was used in selecting 110 farmers from 5 communities in Akoko South East Local Government Area. P...

Yams (Dioscorea rotundata Poir and D. alata Lam.) fungi etiology in Katsina-Ala Local Government Area of Benue State, Nigeria

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. ...

Evaluation of Antagonistic Effect of Trichoderma Harzianum against Fusarium oxysporum causal Agent of White Yam (Dioscorearotundata poir) Tuber Rot

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...

Antifungal Potency of Some Plant Extracts in the Control of White Yam (Dioscorea rotundata poir) Tuber Rot

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...

Fungicidal Effect of Azadiracta Indica and Zingiber Officinale Extracts in the Control of Fusarium Oxysporum and Rhizoctonia Solani on Tomato (Solanum Lycopersicum) Fruits

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 in In Vitro Control of Colletotrichum Species, Causal Agent of Yam (Dioscorea rotundata Poir) Tuber Rot

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...

In Vitro Antagonistic Potential of Trichoderma harzianum for Biological Control of Fusarium moniliforme Isolated from Dioscorea rotundata Tubers

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...

Fungal Organisms Isolated from Rotted White Yam (Dioscorea rotundata) Tubers and Antagonistic Potential of Trichoderma harzianum against Colletotrichum Species

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 of Five Crude Plant Extracts and Chemical Fungicide in in vitro Control of Aspergillus flavus, Causal Agent of White Yam (Dioscorea rotundata) Tuber Rot

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...
