    COST-BENEFIT ANALYSIS OF RICE PRODUCTION UNDER WEED CONTROL METHODS IN LAFIAGI AREA OF KWARA STATE, NIGERIA
    (Department of Agricultural Economics and Extension,Nasarawa State University, Keffi, 2011-10-06) Ibrahim, U.; Rahman, S. A.; Babaji, A.; Danmaigoro, O.
    Field experiments were conducted toevaluate the profitability of rice production at Lafiagi, Kwara State, Nigeria. Tfc= treatments consisted of 15 weed control methods. The treatments were laid out in a randomized complete block desigt— replicated three times. Results revealed that the use of Top star (Oxadiargyl 400 g/l)as pre emergence herbicide a— the rate of 0.8 liters ha1 and any of the following post emergence herbicides; Solito (300 g Pretilachlor + 20 g pyribenzoxim ) at the rate of 1.5 liter ha \ Orizo plus (360 g Propanil + 200g 2,4-D ) at the rate of 10 liters ha Nominee Gold (Bisbyribac sodiumlOOS.C ) at the rate of 0.4 liters ha1 and Profit (170 g Pretilachlor +330g propanil) at the rate of 6 liters ha1 at 6 WAS produced significantly higher yields and higher gross margin as compared to the control ( hoe weeding at 3,6 and 9 WAS) and other treatments considered in this trials. The use OjB Topstargave the highest cost- benefit return ofN7.1,122% gain over the control, followed by the use ofTopstar ancm application of Nominee at 6 WAS thatproduced cost- benefit returns ofN5.8,80% gain over the control. Application ofTopstar and roe weeding at 6 WAS also gave N5.6, which is 75% higher than the control. Labour requirements were reduced by the application of Topstar. It was concluded that herbicides application has increased yield and profitability of rice production and labour demand was reduced. It was therefore recommended that for successful rice production the use of per emergence herbicides and post emergence herbicides should be adopted by farmers in the study area.

    EFFECT OF DEFOLIATION AT DIFFERENT GROWTH STAGES ON YIELD AND PROFITABILITY OF COWPEA (VIGNA UNGUICULATA (L.) WALP.)
    (Department of Agronomy, Nasarawa State University Keffi, 2008-07-06) Rahman, S.A.; Ibrahim, U.; Ajayi, Folorunso A.
    The defoliation of cowpea in the vegetative stage significantly decreased grain yield and profitability, while percent intensity of the defoliation provided the highest grain yield and profit in the cowpea production.

    Health Risk Assessment of some Cosmetic Products sold in Keffi Markets, Nasarawa State Nigeria
    (Department of Biochemistry and Molecular Biology, Nasarawa State University Keffi, 2019-03-07) Idris, M.M.; Ibrahim, U.; M.D., Maryam; Yusuf, S.D.; Muhammad, Abdullahi Ubana
    This study assesses the health risk associated with exposure to heavy metals in various brands of cosmetics sold in Nigeria market using the x-ray fluorescence spectroscopy Analyzer. Eight heavy metals were measured in thirty two cosmetics samples (ten talcum powder, ten pressed powder, six dental powder, four eye shadow, four eye liner, and two hair dye) commonly used in local market and super markets in keffi, Nasarawa state. The concentration of heavy metals such as Cd, Pd, Cr, Zn, Mn, Fe, Cu, Ni was determined. The Systemic exposure dose, Margin of safety, Hazard quotients and Hazardous indices were determined. Results shows that, the range of mean concentrations of metals in the cosmetics sample are Cd (0.216 -1.46 µg/g), Pd (53.628- 267.962 µg/g), Cr (18.571- 30.631 µg/g), Zn (10.443 -315.746 µg/g), Mn (77.693 - 256.319 µg/g), Fe (123.081 - 632.828 µg/g), Cu (9.285 - 36.126 µg/g), and Ni (8.603 – 48.887 µg/g). The hazard quotients were found to be greater than 1,which indicates the risk of carcinogenesis. The systemic exposure dosage (SED) values for these metals acquired from the personal care products were below the WHO limit of 100. The margin of safety values obtained were greater than 100, indicating that the concentrations of metals investigated in these facial cosmetics exert no risk associated with their occurrence in these products. The maximum value of oral cancer risk was detected in Hair dye and the minimum value in eye Liner. Conclusively heavy metal content within the studied cosmetic were ordered as Fe>Pb>Mn> Zn > Cr > Ni > Cu> Cd at all cosmetics. Eye linerhas the highest MOS values which indicate that there is little risk associated with the concentration of metals in eyeliner. HQ value was higher than 1 indicated that the overall risks in both exposure pathways are not within safe level. HI value washigher than 1.
