Abstract: This study was initiated to examine pesticide residue in groundwater system in Ishiagu. Some objectives were also put forth to aid the achievement of the study aim amongst which are to; examine the quality of groundwater in Ishiagu, determine the type of pesticide residue in the groundwater system, determine the level of concentration of different kinds of pesticides residue in groundwater system and also determine the potential health effects of the consumption of pesticide residue concentrated water. Two hypotheses were tested in the study. The study used water samples from 5 wells located in different sub-communities; hence water quality analysis was done for physicochemical parameters of the water samples from the wells and after that for pesticide residue in the wells. The interest Physico-chemical parameters are; pH, Temperature (0C), Conductivity (µS/cm), Resistivity (mΩ), Salinity (mg/l), Total Dissolved Solid (mg/l) and Dissolved Oxygen (mg/l) while the pesticide residues are; DDT, Gammaline, Altrazine, Carbonfuran, Eltrazine, Paraquat, Aldrin and Chlordane. Descriptive statistics and ANOVA were used to test the study hypotheses. The study showed that Conductivity amongst the physicochemical parameters tested was the only parameter that the wells' value exceeded the WHO acceptable limits. The study also showed that the water quality of the wells in Ishiagu is polluted and that the presence of DDT, Gammaline, Chlordane, Aldrin, Carbonfuran, and Altrazine in concentration level above the WHO acceptable level shows the potential impact of the consumption of water from the area. The study recommended Government intervention in potable water provision, having found that the water available to the people is polluted, and Agro education and enlightenment in the area to ensure that pesticides are applied rightly in quantity and in accordance to land size. © International Journal of Ground Sediment & Water, ©Sun Jichao.

Abstract: The study was conducted to identify adaptable, high biomass and seed yield of Cowpea genotypes. Three Cowpea genotypes Bole, 6786 and 2351 were tested in a randomized complete block design (RCBD) with three replications. The result revealed that days to 50% flowering, days to seed maturity, plant height and seed yield was significantly (P<0.05) differ among treatments. Among the tested genotypes late matured was obtained from genotype 6786 (131) days while late genotype was obtained from 2351 (113 days). The highest value of plant height was measured from genotype 6786 (132.8 cm) whereas the short plant height was obtained from genotype 2351 (64.8 cm). The highest seed yield was produced from Bole genotype (24.18 qt/ha) whereas the lowest seed yield was obtained from genotype 6786 (6.8 qt/ha). Chemical composition indicated genotype 2351 was the highest in total ash (TASH) and neutral detergent fiber (NDF) whereas less in crude protein (CP) genotype 6786 was the highest in crude protein (CP) while Bole variety had the highest in dry matter (DM), acid detergent lignin (ADL), acid detergent fiber (ADF) and organic matter (OM). The result of this study implied that 6786 genotype was well adapted and being productive regarding the plant height (131.8 cm) and biomass yield (4.4 t/ha) which is hopeful to fill the gap of low quantity ruminant feed. In addition, the nutritional values were promising particularly the crude protein (CP) in 6786 genotype. Thus it could be possible to conclude that cowpea genotype especially 6786 used as a protein supplement. Based on its adaptability, high biomass, plant height, good CP content 6786 genotype is recommended for further promotion in the midland of East Guji zone and similar agro-ecologies. © International Journal of Ground Sediment & Water, ©Sun Jichao.
