    Effects of Allelochemical of Jatrophacurcas L. Leachate on Germination and Rooting of Four (4) Pepper (Capsicum) Species
    (Department of Biological Science, Nasarawa State University, Keffi, 2020-09-03) Ubazi, C.C.; Abdulkarim, B.M.; Yahaya, S.A.; Sani, M.H.; Aliyu, R.H; Anadi, A.C.
    A study was carried out on the effect of allelochemicals of Jatrophacurcas L. on germination and rooting of four pepper species (Capsicum spp) in the Department of Plant Science and Biotechnology Laboratory, Nasarawa State University Keffi, Nigeria. Data was collected on percentage inhibition and shoot length. Results generatedfrom the study showed that there were significant differences among the values of treatments (4%, 8%, 12%, 16% and 20%) and the control (0%) and within the treatments at P ≤ 0.05 level of significance. Eventually all the test samples were said to be affected by various sort of range of concentrations of the aqueous extracts and the most obvious (i.e most significant) effect was at 12%, 16% and 20% concentrations of the extracts in all species respectively. Germination and early rooting were retarded (delayed) completely at higher concentrations in virtually all the cases when placed in comparison with the control sample. The inhibitory (retardation) effect was seen to be relyon concentration and may also be due to the presence of water soluble allelochemicals like phenols, tannins and azelaic acid.

    The In vivo Trend Analysis of Kidney Function Indices and Lipid Profile of Albino Rats Administered Palm-Wine
    (Department of Biochemistry, Nasarawa State University Keffi, 2021-03-22) Haruna, Sunday Gambo; Enemali, M.O.; Asogwa, O.B.; Sani, M.H.; James, B.A.
    The present study evaluated the dynamics of kidney function indices and lipid profile of albino rats after administration of palm-wine to them. The fresh palm-wine was collected from a local palm-wine tapper on daily basis and divided in to two portions. The first portion was labelled “Fresh palmwine” and administered (15 ml/kg) to group 2 and (30 ml/kg) to group 4, the second portion was allowed to ferment for additional ten hours and labelled “prolonged-fermented palm-wine” and administered (15 ml/kg) to group 3 and (30 ml/kg) to group 5. Group one served as the control and received distilled water, all for 28 days. Each group was randomly allocated four rats. Results (mmol/ml) revealed a significantly(p<0.05) lower concentration of urea (10.21±0.40), higher creatinine (0.37±0.17), K+ (4.06±0.06) and Cl- (86.12±4.61) in group 2 when compared to the control; 11.035±.110, 0.395±0.06, 3.945±.064, 80.090±0.25 respectively. In group 3, the concentrations of urea (11.70±0.35), creatinine (0.42±0.12) and Cl- (88.57±0.50) were significantly (p<0.05) higher when compared to the control. Na+ (120.09±10.40) was significantly (p<0.05) higher in group 4 when compared to the control (100.065±0.75). TAG (in mg/dL) (2.18±0.10) was significantly(p<0.05) higher in group 2 compared to control (1.96±0.023). T. cholesterol (3.125±0.27) and LDL-C (1.64±0.47) were significantly (p<0.05) lower in group 3 compared to the control; 1.99±0.052, respectively with significantly(p<0.05) elevated HDL (1.11±0.22) compared to control (0.840±0.092). TAG (2.190±0.25) and HDL-C (1.15±0.23) increased significantly(p<0.05) while LDL-C (1.58±0.14) decreased significantly (p<0.05) in group 4 compared to control; 1.960±0.023, 0.840±0.092, 1.985±0.052 respectively. T. cholesterol (2.93±0.08) and LDLC (1.56±0.03) decreased significantly(p<0.05) with significant(p<0.05) increase in HDL-C (0.99±0.10) in group 5 compared to the control. Fresh and prolonged-fermented palm-wine may adversely affect kidney function indices and lipid profile.

    INVITRO EFFICACY OF LIME PEELS FOR THE CONTROL OF COWPEA WEEVILS (Callosobruchus maculatus L. Walp) IN KEFFI, NIGERIA
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi., 2019-06-12) Abdulkarim, B.M.; Yahaya, S.A.; Oroja, N.; Sani, M.H.; Aliyu, R.H.
    In order to evaluate the efficacy of lime (Citrus aurantifolia) peels in the control of cowpea weevils, a study was carried out on stored infested and non-infested cowpeas seeds which were treated with 5g of powdered lime peels and 2g of dress force. The control did not include any of the two potential pesticides. The infested seeds were covered with net of 0.2mm mesh size to prevent the entry of insects and to aid ventilation, while the non-infested cowpeas were left opened for natural weevil infestation. The effects of these treatments for infested and non-infested seeds were evaluated using different doses of the treatments. Results showed that the presence of the two pesticides had significant (P < 0.05) effect on the mortality rates of weevils in all the days but was higher in powdered 5g powdered lime peels between days 17 and 19 with the values (12.33 and 12.00) which is higher than the 2g dress force of the same day with the values (8.00 and 14.00) but was lowest in the control in the same day with the values (5.33 and 6.33) respectively, this also caused a reduction in number of seeds infested and number of adults weevils eggs laid. Significant differences were observed at (P< 0.05) on the effect of the lime peels on C. maculatuscompared to the control, treatment of both infested and non-infested cowpeas. Limepeels were found to be efficacious in the management of cowpea weevils (C. maculatus) in storage which is more environmentally friendly.
