C. Tef fields were randomly selected at 5-10 km intervals along accessible routes. The result showed head smudge prevalence and intensity varied across locations within the zone and among districts. From a total of forty-two fields surveyed during main and belg seasons (twenty three fields during the main season and ninteen fields during belg season) were assessed. Quncho was the most prevalent 34.78% and followed by Magna having the prevalence of 26.1% during the main season. Of the assessed areas, the highest incidence was observed in Sokoru districts of Jimma and Wondogenet of West Arsi Zone accounting for about 100% and with the mean severity value of 97%. The highest mean value of incidence was recorded on varieties Tesfa and Quncho with the mean value of 100 and 83.33% followed by local tef variety (80%) during the main cropping season, respectively. During Belg season survey, Boset was the most prevalent accounting for about 68.4% of the assessed areas and followed by Magna variety with the prevalence of 15.79% of the area assessed areas. Efforts should be made towards the integration of multiple disease control options. Varietal diversification is also another issue to minimize the effect of this disease. This study indicates that there was no use of fungicide to control this disease. Currently, the disease was becoming severe, and using fungicide may be an option to control this disease. The other issue is the screening of germplasm to this disease and selecting that tolerant or resistant line (s) and incorporating in the breeding program will also another option to control this disease in the future.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133649733","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}

The groundwater resources in the State plays an important role in the socio-economic life of the people in terms of domestic, industrial and agricultural water supply. The effect of climate change, on the surface and groundwater resources, couple with the anthropogenic and geogenic activities on the quality of the various groundwater sources remained uncertain. Two hundred (200) water samples were collected randomly from boreholes and hand-dug wells from five locations (20 each) in Nasarawa South: Keana, Obi, Lafia and Awe Local Government Areas of the State, referred to as Middle Benue trough. 100 samples were collected during peak of dry season and another 100 during peak of rainy season. Cations, anions and heavy metals were analyzed using atomic absorption spectrometry (AAS); with aim of determining their concentrations in relation to suitability within the tolerance limit. The results revealed that heavy metals such as lead (Pb), manganese (Mn), Magnesium (Mg) and arsenic (As) have concentrations above World Health Organization (WHO 2017) and SON (2015) standards. The high concentrations are mostly associated with the Baryte and Lead-zinc mineralization present in Keana / Awgu formations in the Middle Benue Trough. Zinc (Zn), copper (Cu), cadmium (Cd), and iron (Fe2+) have their concentrations within World Health Organization (WHO 2017) drinking water permissible limits. The cations and anions present in the groundwater in the study areas had varying levels in terms of physico-chemical and bacteriological quality. In some areas bacteriological contamination rendered water sources unfit for human consumption, but suitable for agricultural purposes. Therefore, regular monitoring of the water sources in the affected areas are highly recommended.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131924985","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}

Water deficit is one of the main causes that strongly affect the productivity of woody species. Thus, the promotion of tolerant varieties that can withstand the uncertainty of rainfall and its deficits is a solution to adapt to the effects of climate change. The study of the tolerance of four provenances of Anacardium occidentale L under drought stress conditions (12.5%, 25%, 50% and 100% of field capacity) was carried out in a semi-controlled environment. The measurement of height, total dry biomass, collar diameter and root length and relative water content, allowed us to obtain the results on the growth and physiological reactions of Anacardium occidentale provenances under water stress. At a high level of drought stress (12.5%), the best growth was obtained with plants from the Ziguinchor provenance, which had higher survival rates, heights, collar diameters and relative water content than the Kolda, Sédhiou and Goudomp provenances. These results show that the Ziguinchor plants provenance is more tolerant to water stress than the other provenances tested. This study recommends the use of the Ziguinchor Anacardium occcidentale provenance to fight against the effects of climate change in Casamance (Senegal).","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130350440","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}

This toxin is produced by Aspergillus flavus in food and feeds results in adverse health effects for humans and animals, as well as economic barriers to farmers and countries. This study aimed to assess the awareness of farmers in harvesting and postharvest handling practices for the management of Aflatoxin in maize. The assessment was conducted using questionnaire to capture data on bio-data information, farmer’s awareness on aflatoxin contamination, harvesting time, post-harvesting practices, and storage facilities. Statistical analyses were performed using Statistical Package for Social Science (SPSS) version 25. The result shows that 65.63% of farmers in Kilosa and 67.28% of farmers in Gairo districts were aware of aflatoxin contamination. The study revealed that, during harvesting time, 92% of farmers at Kilosa and 98% of farmers in Gairo district harvest maize when completely dry. In drying practice, the use of canvas had higher usage compared to other practices where 42.70% of farmers in Kilosa and 16.70% of farmers in the Gairo district were using canvas. Additionally, it was observed that the majority of farmers in both districts store their maize by using storage bags/sacks that favor the rise of insect/pest contamination. The study suggests that there is a need for establishing an educational campaign for maize farmers on the effect of aflatoxin contamination to improve their awareness. The knowledge should base on harvesting, drying practices, and modern storage facilities that can reduce aflatoxin contamination.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115587669","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}

Both descriptive and inferential statistics were used for the data analysis. Results showed that both minimum and maximum temperatures in Uyo increased with increasing time while the monthly mean minimum and maximum temperature decreased from January to December. The mean total heat index continued to rise at the rate of 0.13381 in Uyo. The mean total heat index increased at the rate of 0.1998 in the dry season and 0.0968 in the rainy season in Uyo. The study concluded that the air temperature and relative humidity in Uyo are increasing from 1985 to 2021 while solar radiation and wind speed are slightly decreasing. However, the heat index in Uyo was increasing from 1985 to 2021 and as a result the human comfort in the outdoor environment becomes a challenge.

This crop is susceptible to several viral diseases, including Cassava Mosaic Disease(CMD) and Cassava Brown Streak Disease(CBSD) in eastern DRC. Following earlier studies that show root necrosis occurring in western DR Care not due to CBSD but to Cassava Root Necrosis Disease (CRND), an exploratory survey was conducted in western DRC from 2016 to 2017 in order to determine the distribution, the severity and the incidence of this disease (previously known as CBSD-like disease). NGS ( Next Generation Sequencing) results confirmed all the previous negative results obtained using PCR and CBSV primers. This suggests that microorganisms such as bacteria or fungi could be responsible for cassava root necrosis in western DRC and is not CBSD as predicted. Five provinces (Bas-Congo, Kinshasa, Bandundu, Equateur and Kasai-Oriental) were surveyed and data were collected according to the harmonized protocols adopted by countries within the West African Virus Epidemiology (WAVE) project. Statistical tests (ANOVA) performed on our data showed that CRND severity did not vary significantly among the provinces of Kinshasa, Bandundu and Bas-Congo which are the areas most affected by the disease. Bas-Congo and Kinshasa provinces presented the highest maximum disease severity (score 3 and 5 respectively), while Equateur province had the lowest disease severity score. Equateur province also had the highest percentage of healthy plants and few plants presented mild symptoms. The overall average of cassava root necrosis severity in western DRC ranged around 1.88 ± 0.08, an approximate score of 2. The overall mean incidence of CRND in western DRC was 22.24 ± 2.4% but reached 100% in localities considered as hotspots (Lukuakua in Bas-Congo and Nguma in Plateau des Batékés). The behaviour of cassava varieties against CRND is similar with CBSD in East Africa, most of improved varieties and landraces are susceptible to both diseases. Correlation analyses showed a positive correlation (r = 0.6940) between severity and incidence of CRND. Therefore, Bas-Congo province is the most affected province, while the province of Equateur is the least affected province in western DRC.

However knowledge remains relatively sparse on crop response to incremental rates of P2O5 fertilization on soils of known P levels to serve as proxy for development of site-specific P2O5 predicting tool that is required for optimum maize production. In the P-deficient Lixisols of northern Ghana, the effect of eleven rates of P2O5 fertilization were evaluated for growth and yield of maize. The P2O5 rates used were 00, 05, 10, 15, 20, 25, 30, 35, 40, 45, and 50 kg/ha; laid out in a Randomized Complete Block Design with four replicates. Data were collected on maize growth and yield and subjected to analyses of variance, where means were separated at a probability of 5% using the least significant difference. Results of the evaluation indicated significant effect of P2O5 rate on maize plant height, leaf area index, days to 50% flowering, cob weight, cob length, 100 seed weight, straw weight and grain yield. Increasing P2O5 rates had pronounced effect on growth, on grain yield and on yield components of maize. Application of 50 kg/ha resulted in maximum leaf area index (3.84), 100 seed weight (23.49 g), straw weight (9.3 t/ha) and grain yield (3.09 t/ha) as compared to the minimum values in the control treatments (1.57, 14.8 g, 3.3 t/ha and 0.71 t/ha respectively). The findings show that phosphorus fertilization is essential for maize growth and yield and serves as an entry point for relating soil test data with corresponding yield and the subsequent development of a fertilization tool that can help to predict site-specific P2O5 fertilization, based on soil test results.","PeriodicalId":364314,"journal":{"name":"International Journal of Agriculture, Environment and Bioresearch","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114337488","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}
