The natural coagulant was Moringa oleifera seeds (a forest plant) i.e Treatment ‘A’ while the chemical used was Aluminum hydroxide chloride i.e Treatment ‘B’. The aim of this study was to compare the use of a natural coagulant with a chemical coagulant.  Samples were collected at Omida,  Ibara, Mama Cass, Mr Bigg’s and Sidipon village respectively. The filtrate of   Moringa oleifera seed extract was dosed into the greywater sample at 10% dosing range and made to run through a greywater treatment plant while Aluminum Hydroxide Chloride was also dosed at 10% dosing range and made to run through the treatment plant respectively. The greywater treatment plant   is a self designed treatment plant made to treat both water and wastewater. The raw water was firstly analyzed, after which the treated samples were taken to the laboratory for analysis.  Result for the physical, chemical and bacteriological analysis of treatment ‘A’ before and after treatment were as follows: pH (9.3, 9.7), EC (2995, 1175μs), Temperature (27.7, 27.6oc) , TDS (365, 155ppm),  TSS (0.32, 0.30ppm), TS (376, 155ppm), Sulphate (588, 314mg/l), Magnesium (400, 260mg/l), Nitrate (7.5, 6.1mg/l), Phosphate (285, 12mg/l) and total coliform count after treatment is given as (2.8x103 cfu/ml), while that of treatment ‘B’ before and after treatment were as follows: pH(11, 9.9), EC (3000,630), Temperature (27.7, 27.6oc), TDS (0.47, 0.45ppm), TS (416, 320ppm), Sulphate (571, 246mg/l), Magnesium (820,  860mg/l), Nitrate (4.4, 6.0mg/l), Phosphate(169, 6.1mg/l)  the  total coliform count after treatment was  given as ; (3.0x103cfu/ml). One-way Anova test was used to determine differences between results obtained using the two coagulants. The result indicated no significant difference at p=0.05 between the two treatments. Hence, result was further compared with World Health Organization Standard for Drinking Water.  Comparatively, the analysis obtained from water treated with Moringa oleifera was found to be more effective than the chemical coagulant, and can be easily made available for the use of the populace. \u0000  \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114299573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighty rural children were sampled from four fishing communities across two wards in the LGA through the use of multistage sampling technique. Data were collected with structured interview schedule. The study identified fishery activities involved in by rural children, determined their level of involvement, identified their educational activities and also identified reasons for children’s involvement in fishery activities. The results indicated that majority of the rural children were male (71.25%) with mean age of 14 years, Christians (61.25%) and had large household sizes between 6 and 10 persons (77.50%).Smoking of fish (96.25%), fish catching (93.75%), firewood gathering (92.5%) and selling of fish (88.75%) were some of the fishery activities involved in by rural children. The study also revealed that high level of involvement was observed with fish processing and fish marketing activities. Despite children’s involvement in fishery activities, their educational activities were not affected. The results of Chi-square analysis also showed significant associations between rural children’s involvement in fishing activities (χ2 = 210.772, p<0.05), fish marketing activities (χ2 = 163.547, p<0.05) and their educational activities. The study concludes that if children’s level of involvement in fishery activities is low, their educational performance will not be affected. It is therefore recommended that children’s involvement in fishery activities should only be tailored towards socializing the children and not for children to be exploited through child labour. \u0000  \u0000  \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127082800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 208 respondents made up of 106 women producing Kokoro (Corn snack) and 102 women producing arable crops to serve as control group were selected. The respondents were selected based on non- probability method. Purposive sampling technique with Snowball method was used. Data were obtained by structured interview schedule. Data collected were analysed using FGT poverty index, costs and return and t-test statistics. The results indicated that 34.9kg of maize were processed into 128 dozens of Kokoro (Corn snack) per production run over an average of five (5) days, with six (6) production runs per month for nine months for the period of the research. The mean Kokoro (Corn snack) production cost was N42, 769.41/ respondent/ month with average revenue of N92, 253.60/ respondent/ month and net income of N49, 484.19/ respondent/ month. Income from Kokoro (Corn snack) production accounted for 53.4% of the total household income of N721,323.67 of an average woman engaged in Kokoro (Corn snack) production while farm income  accounted for 67.9% of the total household income of N418, 935.10 of an average woman producing arable crops. The study also revealed that households of Kokoro (Corn snack) producers had mean per capita household income of N282.32 per person per day which was significantly higher (p<0.01) than those of women producing arable crops, N191.29 per person per day. Thus Kokoro (Corn snack) production has the potentials to enhance income and reduce poverty among households of rural women. The study thus recommends promotion of value- adding activities, such as maize processing into Kokoro as a means of enhancing income and reduces poverty among the rural folks. \u0000  \u0000  \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128015363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study identified and assessed the effects of human activities on the function and utilization of some dams in Kano State, through field observations, interview and analysis of relevant data. The results indicated that various human activities such sand excavation along the spillway, clearing of vegetation for irrigation and farming within the perimeters of the dams have led to serious gulley erosion and consequently large quantities of sediment transported and deposited (siltation) in the bed of the dams, while the use of agrochemical for irrigation led to rapid emergence and growth of aquatic grasses due to eutrophication, thus leading to increase in turbidity and channel blockage which impedes smooth water supply in the downstream areas. The result also shows that the reservoirs installation capacities are declining with age at different alarming rates due to sedimentation. Marashi dam remarkably declined by 18%, Pada and Magaga dams each reduced by 15.5% and Guzu-Guzu dam suffered 15.4% reduction. Watari dam is reduced by 14% while Gari, Tomas, Karaye and Challawa-Gorge dams declined by 6.4%, 7.5%, 8.5% and 9.08% respectively. This rate of capacity reduction of the reservoirs due to sedimentation spanned within 45years of existence (1971-2016) which makes the state losing a whopping 5.75M 3 Mil of water annually.

Human shave also used this process to transport the animal for commercial purpose. To examine the effect of this physiological process on reproductive apparatus, thirty (30) Giant African Land snail (Archachatinamarginata) with average weight of 130 -150g were used for this study. The snails were allotted to three different treatments with ten (10) replicate each after four weeks of acclimatization period which include: zero (0) week, three (3) weeks and six (6) weeks of aestivation. Parameters measured were: Internal organ weight, ovo-testis weight, reproductive tract length (cm) and weight (g). Also gonado-somatic index and spermatozoa concentration were also determined. Results showed that aestivation duration had significant influence on organ weight, ovo-testis weight, reproductive tract length and weight and spermatozoa concentration. However, gonado-somatic index (GSI) was not significantly influenced. It was observed that organ weight decreased as aestivation duration increased. For ovo-testis, snails with aestivation duration of six weeks had smaller weight compared to the control (0 week) while those at three weeks aestivation duration were not significantly different from the control group and those of six weeks aestivation duration. For reproductive tract weight, there was a significant(P<0.01)decrease in weight of the tract for both snails under three and six weeks aestivation duration compared to the control group (0 week). Spermatozoa count also decreased as aestivation duration increased. It can therefore be concluded that aestivation duration had significant effect on organ weight, ovo-testis weight, reproductive tract weight and spermatozoa concentration.
