Item Development of a Negarim Micro-catchment System for Citrus Production(Department of Forestry, Wildlife and Range Management, University of Agriculture, Makurdi, Nigeria, 2019-03) Ayanshola, A.M.; Dauda, K.A.A Negarim Micro-catchment System can be considered as a rudimentary form of irrigation and it is a directly productive form of soil and water conservation which focused on harvesting and conserving rainwater for improved crop productivity. The system was designed and constructed. The system consists of the catchment area, cultivated area, runoff plot, runoff gutter and collection tank. Results of the analysis revealed that on average, an annual rainfall of 1,233.6mm or higher can be expected at 50% probability of occurrence and at average frequency of occurrence of 1,233.61mm or higher can be expected a 50% probability of occurrence of 2½years interval. The results also showed that the mean runoff coefficient for the catchment throughout the period of observations is 0.48, the average value of crop water requirement is 3.63mm/month, the chemical analysis results also showed that the salinity, infiltration rate, toxicity and fertility level of the soil in the study area are satisfactory and suitable for citrus production and finally, the average catchment-cultivated area ratio (C:CA) is 1.0478. However, if the available rain can be concentrated on a small area, through water harvesting system, both yields and reliability of production can be significantly improved.Item On the Strength of Agreement between Initial and Final Academic performances in a Nigerian University System(ABACUS, Mathematical Association of Nigeria, 2018) Banjoko, Alabi; Yahya, Waheed; Abiodun, H. S.; Afolayan, Razaq; Garba, Mohammed; Olorede, K. O.; Dauda, K.A.; Adeleke, Mariam O.This paper examines the strength of agreement between academic performances of students after their first and final years in the University. Academic performances of a total of 886 students that were admitted into various academic programs in the Faculty of Science, University of Ilorin, during the 2008/2009 academic session were followed-up to their year of graduation in 2012. Information on the grade point average (GPA) of students at the end of their first year in 2008, their final cumulative grade point average (CGPA) at the end of their studies in 2012 among others were collected. Results from this study generally showed a fair agreement between students’ initial and final academic performances in Nigeria University system (p < 0.001). It was also found that about 50% of students maintained the classes of degrees they had in their first year till graduation, about 40% of them improved on their performances while the performances of about 7% of them dropped from what they had at their first year. Further results showed that students’ performance is gender sensitive. Specifically, about 45% and 60% of female and male students maintained the classes of degrees they had during their first year in the University, about 50% and 30% of them improved on theirs while about 5% and 10% of them dropped from their initial academic performances at the end of their studies respectively. Finally, students in the Biological Sciences improved on their initial academic performances more than their counterparts in the Physical Sciences. Also, female students improved on their initial academic performances more than their male counterparts. This work will serve as useful counselling guide to prospective admission seekers into the Universities and all the stakeholders at enhancing students’ academic performances in the University system.Item On the Strength of Agreement between Initial and Final Academic performances in a Nigerian University System(ABACUS, Published by Mathematical Association of Nigeria, 2018) Banjoko, A.
