Vegetables are the commonest agricultural commodity that are grown around the river bank and are averagely the most consumed food product in Nigeria. An investigative screening of metallic contamination of Amaranthus spp grown in three farms around river Ibi bank showed a level of metallic deposition: Cadmium (Cd), (2.25±0.63, 3.28±0.55, 2.51±0.03) ppm; Lead (Pb), (1.83±0.51, 0.54±0.03, 1.06±0.13) ppm; Mercury (Hg), (0.53±0.01, 1.03±0.01, 0.66±0.01) ppm; Arsenic (As), (0.50±0.72, 0.51±0.06, 0.62±0.15) ppm and Chromium (Cr), (4.26±0.51, 2.66±0.22, 1.75±0.38) ppm. Descending order of the mean concentrations of the trace metals detected from analyzed sample of Amaranthus spp from the three locations are as follows; Farm A: Cr>Cd>As>Pb>Hg, Farm B: Cd>Cr>Hg>Pb>As, Farm C: Cd>Cr>Pb>Hg>As. Amaranthus spp cultivated along Ibi river bank has shown a reasonable amount of deposition of heavy metals, therefore, are not totally safe. The metallic content in Amaranthus spp sample collected in farms along Ibi river bank ranges; 0.50±0.72 to 4.26±0.51 in sample A, 0.51±0.06 to 3.28±0.55 in sample B and 0.62±0.15 to 2.51±0.03 in sample C. The metallic deposition detected from analyzed Amaranthus spp showed values that are above the World Health Organization set permissible limit (Pb-0.3ppm; Cd-0.2 ppm; As-0.5ppm; Hg-0.5ppm; Cr-0.5ppm). Bioaccumulation of these metallic substances in the human system as a result of long-term consumption of the vegetables poses a deleterious health effect. This study aimed at ascertaining the food safety of agricultural products cultivated around Ibi river bank.","PeriodicalId":363511,"journal":{"name":"African Journal of Biological, Chemical and Physical Sciences","volume":"613 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127524845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A research survey design was used for the study and fifty (50) local rice farmers were randomly selected from 17 different communities in Abakaliki LGA. Descriptive statistics and multiple regression were employed in the data analysis. Results showed that most of the rice farmers sampled were of their active age with an average of 35 years. The respondents possessed one educational qualification or the other. The Size of the farm, labour input, capital inputs, and cost of seeds exerted significant influence in explaining the variations in the quantity of local rice produced. The R2 (0.766), showed that 76.6% of the variations in the output of local rice were captured by the explanatory variables. It is recommended that local rice farmers increase their small farm sizes either through the acquisition of more lands directly or through government efforts at a fee. Furthermore, since labour input significantly influenced the output of Local rice it is recommended that skilled labour be attracted into local rice production through increased remuneration of labour in rice production. Capital inputs should be increased in the study area probably through credit liberalization or skewing of credit supply in favour of local rice production to enable the farmers to hire skilled labour needed to boost rice output.","PeriodicalId":363511,"journal":{"name":"African Journal of Biological, Chemical and Physical Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122384473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
