Item Utilization of post-harvest technologies among Yam Farmers in Selected Local Government Areas of Niger State, Nigeria(Proceedings of the 1st International conference of agriculture and agricultural Technology, 2019) Hassan, S.; Salihu, I.T.; Abdullahi, A.; Aliyu, A.Yam is an important tuber crop in Nigeria. However, its availability is affected by rate of deterioration arising from poor postharvest handling. Hence, farmers use various techniques to minimize the loss. Therefore, this study examined the utilization of post harvest technologies among yam farmers in selected local Government areas of Niger state, Nigeria. Data were collected from 195 respondents and analyzed with descriptive statistics. The result revealed that, the mean age of the respondent was 35.0 years and highly experienced in food crops production with mean of 18.0 years experience. Majority of the respondents (79%) had formal education. However data analysis reveals that yam barn storage technique ranked first in terms of types and level of utilization by the farmers with the highest weighted mean (WM=3.87) while, open sided shelve was the least (WM=1.43). It is therefore recommended that extension agents should actively disseminate information on improved storage techniques to yam farmers in the study area as well as the need to use such techniques.Item Partial Replacement of Fine Aggregate With Waste Glass in Concrete Made From Bida Natural Aggregate(3rd International Engineering Conference (IEC 2019) Federal University of Technology, Minna, Nigeria, 2019) Alhaji, B.; Kolo, D. N.; Abubakar, Mahmud; Yusuf, A.; Abdullahi, A.; Shehu, M.This study reports the experimental investigation on the suitability of waste glass as partial replacement for fine aggregate in concrete made using Bida natural aggregates (BNA). Glass is widely used in our daily lives through manufactured products such as sheet glass, bottles, glassware, and vacuum tubing. It is an ideal material for recycling. The increasing awareness of glass recycling speeds up inspections on the use of waste glass with different forms in various fields. Mix ratio of 1:2:4 batched by weight with water - cement ratio of 0.55 was used. The percentage replacement varied from 0% to 40% at 5% intervals. Slump test was conducted to assess the workability of the fresh concrete. The compressive strengths and densities of cured concrete cubes of sizes 150mm x 150mm x 150mm were evaluated at 7, 21 and 28days. A total of 81 concrete cubes were cast and tested. It was observed that an increase in the percentage replacement of fine aggregate with waste glass reduces workability, density and compressive strength. The compressive strength and density vary with days of curing. The findings of this study indicated that the optimum replacement percentage of waste glass with conventional fine aggregate was 20%. However, waste glass can effectively be used as fine aggregate replacement (up to40%) without substantial change in concrete strength.Item Effects of knowledge of Hand washing, sources of water and Environmental hygiene of farming Households on sustainable Agriculture in North-Central Nigeria(Proceedings of the 1st International conference of agriculture and agricultural Technology, 2019) Salihu, I.T.; G.B. Adesiji; Abdullahi, A.; H.U. MuhammedThe study assess the knowledge of hand washing, sources of water and environmental hygiene practices of farming households in North-Central Nigeria. Multi- stage simple random sampling technique was used to select 256 farming households in the study area. Interview schedule was used to elicit data from the respondents. The responses were analyzed using frequency counts and mean score. The result of the study shows that 38% of the respondents are in the age range of 31 – 40 years with a mean of 36.7 years, they had low level of education and the mean number of number of visits of health service workers to farming households is 3 times/per annum. The results revealed that majority (73.80%) of the respondents are aware of the need to always wash hands after using the toilet but the knowledge on the use soap to wash hand before eating ( 36.30%), preparing food/cooking (20.30%), changing baby’s wear ( 24.20%), after defecating (19.10% ) and before feeding children (18.40%) is low in the study area. Majority of the respondents go their water for household purposes from unprotected sources such as dug well (57%) and bore holes (52%) and the majority (84%) treat their water by allowing it to stand and settle before drinking or before using it for other household purposes which is inadequate and may endanger the farming households to the vulnerability of food and water borne diseases. The use of bush and pit latrine are the major means of defecation in the households and dumping of household waste in a nearby bush is the system of waste disposal always adopted by majority (63.70%) of the households. Health extension workers and the local authorities should establish joint participatory committees to sensitize, motivate and organize food safety promotion programmes on the need to enforce some crucial food safety practices especially hand washing with soap/ash, on the danger of open defecation and poor system of waste disposal.Item Effect of Rural Youths migration on Maize production in Kontagora Local Government Area of Niger State, Nigeria(Proceedings of the 1st International conference of agriculture and agricultural Technology held at Federal University of Technology, Minna, Niger State, Nigeria, 2019) Abdullahi, A.; Baba, K.M.; Salihu, I. T.The study assessed the effect of rural youths’ migration on maize production in Kontagora Local Government Area of Niger State, Nigeria. The specific objectives were to; describe the socio-economic characteristics of farmers; ascertain the causes of youths’ migration, determine the extent of youths’ migration, access the effect of youths’ migration on maize production and identify the problems associated with youths’ migration in the area. To achieve these objectives, 120 maize farmers were randomly selected through multi-stage sampling technique. Data were analyzed using descriptive statistics and multiple regression analysis. The result on socio-economic characteristics shows that majority (52.5%) of the respondents are still in their active age of between 21- 40 years with mean age of 39years. Equally, respondents were males (72.5%), married (77.5%) with Non formal education (40%). Only a few (18.3%) attained tertiary education. Similarly, majority (90%) had a household size of between 1 – 10 persons with average size of 6 persons per household. The average maize farming experience among the respondents was 17 years. The major causes of youths’ migration in the area includes: lack of employment opportunities (90%), furthering of education (77.5%), and lack of access to modern amenities (55%). The extent of Youths migration in the area is relatively moderate (45.8%) with averagely 31 youths leaving each village every year. The peak period of migration is usually during the off-season (50.8%). The result of the regression analysis shows Cob-Douglass as the lead equation. The result revealed that youths’ migration affect production negatively while labour, agro chemicals and fertilizer are positively significant. The problems of youths migration in the area include; loss of cultural values (75%), reduction in rural population (54.2%) and dull village life (47.5). To this end, youths’ migration limits maize production thus, government should provide functional schools and employment opportunities to engage rural youthsItem Assessment of efficient utilization of production inputs among women rice farmers in Niger State, Nigeria(Proceedings of the 52nd Annual Conference of the Agricultural Society of Nigeria, 2019) Yusuf, A.; Tsado, J. H.; Salihu, I. T.; Abdullahi, A.Rural women have feature prominently in rice production enterprise, specifically; up to 70% of the rice produced in Africa comes from women (FAO, 2011). In Niger State, rice is traditionally regarded as a product of women. Women living in this area are having high knowledge about traditional farming methods of rice production. However, low productivity coupled with stiff competition posed by importers over the years has restrained the women farmers from earning significant returns from their investment and this has created rice production deficit. To minimize the effect of the rice production shortfalls on state demand, several efforts have been made by successive governments together with donor partners in a form of implemented projects to increase rice production. However, this effort is still ineffective due to limiting factors such as: inadequate institutional support (access to credit, research and extension), inappropriate production system, inadequate basic infrastructures, production risk and inefficiency on the part of the farmers. In light of these assertions, the challenging question to this review is that ‘can women rice farmers improved on their technical efficiency to reduce production risk and increase output’? Thus, this review seeks to assess the efficient utilization of production inputs among women rice farmers in Niger State, Nigeria.Item Assessment of Crop Farmers’ and Pastoralists’ Perceptions on the Establishment of Cattle Ranches in Niger State, Nigeria(Proceedings of the 52nd Annual Conference of the Agricultural Society of Nigeria, 2019) I. M.Mayaki; H. T. Jacob; I. S. Umar; Abdullahi, A.The Nigeria government have tried in many ways, initiated lots of policy and programmes which is aimed at restoring the country’s agricultural sector to its pride. Despite the efforts to promote positive perception and adoption of innovative technologies (IT) by the Government and international development projects, the adoption rate among farmers has always been low in Nigeria. In continuation, recently the federal government of Nigeria introduced the Rural Grazing Areas (RUGA Settlement).The idea was an initiative of the National Economic Council (NEC) presented under the National Livestock Transformation Plan .The essence of the initiatives to abolish the age-long crop farmers and pastoralists’ crisis and to massively develop the livestock industry and seek to promote ranching as the way forward for cattle rearing in the country. According Alh. Mohammadu Umar, the Permanent Secretary in the Federal Ministry of Agriculture and Rural Development,made it known to News Agency of Nigeria (NAN) in Abuja on 25th of June 2019 that nomadic livestock production in Nigeria is facing major challenges and is at crossroads due to declining availability of pasture, overgrazing, and expanding fatal conflicts between crop farmers’ and pastoralists’.Item PARTIAL REPLACEMENT OF FINE AGGREGATE WITH WASTE GLASS IN CONCRETE MADE FROM BIDA NATURAL AGGREGATE(3rd International Engineering Conference (IEC 2019), 2019-09-22) Alhaji B.; Kolo, D.

The compressive strength and density vary with days of curing. The findings of this study indicated that the optimum replacement percentage of waste glass with conventional fine aggregate was 20%. However waste glass can effectively be used as fine aggregate replacement (up to 40%) without substantial change in concrete strength.Item Partial Replacement of Sand with Sawdust in Concrete Production(3rd Biennial Engineering Conference, Federal University of Technology, Minna, May, 2013, 2013) Abdullahi, A.; Abubakar, Mahmud; Afolayan, A.The rising costs of building construction in developing countries have been a source of concern to government and private developers. This study investigated the use of sawdust as partial replacement for fine aggregates in concrete production. Sawdust was used to replace fine aggregates from 0% to 50% in steps of 10%. Concrete cubes measuring 150 x 150 x 150mm were cast and their compressive strengths evaluated at 7, 14, 21 and 28 days. Increase in percentage of sawdust in concrete cubes led to a corresponding reduction in compressive strength values. From the results, the optimum sawdust content was obtained at 10% and its corresponding compressive strength at 28 days is 7.41 N/mm2 which falls within the characteristic strength of plain concrete (7 – 10 N/mm2). This concrete cannot be used for structural applications.Item Assessment of the Compressive Strength of Concrete Produced with Fine Aggregate from Different Locations in Minna(3rd International Engineering Conference (IEC 2019) Federal University of Technology, Minna, Nigeria, 2019) Aminulai, H. O.; Abdullahi, A.; Abubakar, Mahmud; Abdulrahman, H. S.; Alhaji, B.; Joseph, O. F; Aliyu, S. YThe construction industry in Nigeria has been witnessing serious collapse of buildings resulting from the qualities of materials used in their construction. This continuous collapse necessitates the need to investigate some of the materials used in the production of the building components in order to ascertain their appropriateness. This research thus investigates the compressive strength of concrete produced using fine aggregate from different locations in Minna. Fine aggregates were obtained from Chanchaga, Maikunkele, Bosso, Lapai Gwari and Garatu areas of Minna and subjected to series of tests namely: sieve analysis, Specific gravity, bulk density, moisture content, and water absorption. Concrete samples were produced using the mix ratio 1:2:4 and the water/cement ratio of 0.6. These samples were subjected to both the slump test and compressive strength test. For each of the fine aggregates, nine cubes of concrete (150mm x 150mm x 150mm) were cast, cured and tested at 7, 14 and 28 days. The results obtained for the mean compressive strength of the concrete produced shows that they all have mean strength greater than 20N/mm2 with fine aggregate from Chanchage having the highest mean of 25.17N/mm2 at 28days of curing. Thus all the fine aggregates could be used in the production of structural lightweight concrete but for structures that require higher strength, the fine aggregate from Chanchaga is recommendedItem Development of an Android Based Mobile Application for Design and Detailing of Pad Foundations to BS8110(Epistemics in Science, Engineering and Technology, 2017) Yusuf, A.; Aminulai, H. O.; Abdullahi, A.; Abubakar, Mahmud; Alhaji, B.Many innovative computer software have been developed to perform the task of designing and detailing structural elements such as beams, columns, slabs and foundations. This design and detailing can be done using mobile devices but software developed to operate on such devices have not been fully developed. However, this research is aimed at developing an android based mobile application for the design of pad foundations to Bs8110. The mobile application developed designs isolated axially loaded-only; axially loaded with moment pad footings as well as combined pad footings. The mobile application developed was tested using three typical test parameters and results compared to the manual computations. There was no significant variation in the steel sections required and provided for the manual design and that generated by the mobile application. The steel required by manual design for the axially loaded pad footing was 835mm2/m and that generated by the application was 837.2mm2/m. That of the axially loaded with moment gave required steel section as 1019mm2/m using manual design. This android based mobile application would thus give the structural engineer the leverage to design pad footings anywhere and anytime.
