This Note presents an innovative approach to soil sorptivity determination. A single ring infiltration method, along with a simulation of rainfall of constant intensity, was used to measure ponding time tp. Hydraulic conductivity K was approximated from the analysis of the time series of the process of vertical non-steady cumulative infiltration appearing after the ponding time. Based on Philip's infiltration theory, a simple equation was derived in order to calculate sorptivity S from ponding time, rainfall intensity, and saturated hydraulic conductivity. Numerically determined results of S show to closely correspond with theoretical values published in the literature. To the best of our knowledge, this process of numerical determination of K and S has not been published so far. Moreover, unlike the traditional methods, e.g. single or double-ring in filtration experiments, this method provides more precise and representative values of S, verified by ponding time, as the results refer to the original soil sorptivity, not the sorptivity determined after the ponding time (meaning sorptivity of the fully saturated environment) which tends to reach zero. Our assumption was definitely confirmed by field experimental determination of ponding time and selected soil hydrology characteristics.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"66 1","pages":"33 - 40"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78024977","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 54 Hyline brown Agrited brand pullets were randomly allotted to 3 treatments, 6 birds per replicate. Parkia pulp was included in the birds’ drink (0%, 1%, and 2% parkia pulp) from 08:00 h to 10:00 h followed by clean cool water daily from day 147 to day 245 (early egg production phase). At day 420 to 448 (late egg production phase) conventional multivitamins, 1% and 2% parkia pulp were included in drinking water for 3 days in a week 08:00 h to 17:00 h. Data on the growth of birds, egg production, and egg internal and external quality were measured and analysed using ANOVA at p < 0.05. The weight of birds in the early egg production phase was directly proportional to the quantity of parkia pulp included in the parkia pulp drink. The number of eggs produced per bird (64.85) was significantly higher from the birds on 1% parkia pulp drink, whereas from the egg quality indicators, egg weight (65.03 g), length (56.15 mm), shell weight (8.06 g), and albumen weight (41.75 g) were all significantly higher at 2% inclusion level of parkia pulp drink in the early stage of egg production. In the late phase there was no significant difference among the treatments in the internal and external egg qualities but the weight of birds on parkia drink was high at p ≤ 0.05. The results of our study show that parkia pulp inclusion in commercial laying hen drink enhances the quality and quantity of egg production.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"102 1","pages":"58 - 64"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73903672","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 was carried out to estimate factors influencing the choice of healthcare facilities utilised by rural households. A multistage sampling procedure was used to select 240 rural households comprising 1440 persons. Data were collected with the use of a structured questionnaire and analysed with descriptive techniques and a multivariate probit (MVP) model. The MVP result showed that households supplement public healthcare facilities with private clinics, support traditional medical treatment with self-medication, and replace self-medication with public healthcare facilities and private clinics. Similarly, age, gender, household size, cost of drugs, distance to public healthcare facilities, travelling cost, contact with community health workers, total income, awareness of public health facilities, quality of health facilities, and terrain of health facilities influence the choice of healthcare facilities utilised. The study concluded that increased total income, contact with community health extension workers, awareness of health facilities, and perceived quality of services rendered positively influence the choice of healthcare facilities sorted after while the increase in the cost of drugs, distance to health facilities, travelling cost and difficult terrain of health facilities negatively impact the choice of healthcare facilities utilised. The study recommended that public healthcare facilities should be located within the reach of the people and equipped with essential drugs at a reduced cost. Households should also engage in activities that will increase their income so that they can use better healthcare facilities.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135599784","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}

Growth performance and blood indices of growing turkeys fed diets containing shrimp waste meal (SWM) as substitute for FM were investigated in a 56-day feeding trial using eighty (80) 4-weeks-old male British United Turkeys (BUT). The turkeys were allotted on weight equalisation into four treatments with four replicates of five turkeys each. Four diets were formulated such that FM in the control diet (diet 1) was substituted by SWM at 150, 300 and 450 g/kg (protein for protein) in diets 2, 3, and 4, respectively. The experiment was arranged in a completely randomised design and data collected were analysed using ANOVA. Cost of feed consumed was highest (p < 0.05) for turkeys fed the control diet and lowest for group fed diet 4. Weight gain decreased (p < 0.05) with increasing SWM level in the diet at the grower phase (day 57–84). Turkeys fed the 450 g/kg SWM diets had the lowest (p < 0.05) feed intake. At the grower phase, best feed:gain, cost of feed consumed, feed cost per weight gain and protein efficiency ratio were recorded in turkeys fed control and 150 g/kg SWM diets. Uric acid, creatinine, cholesterol, alanine aminotransferase (ALT), haematocrit, and white blood count differed significantly (p < 0.05) among the treatments at the starter phase. In conclusion, the present study showed that SWM can serve as a potential replacement for FM when substituted at 150 g/kg in the diets of turkeys without any deleterious effect on their performance and haematocrit.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"6 1","pages":"57 - 64"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82224351","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 investigated the utilisation of cassava wastes among processors in Akoko southwest, Ondo State, Nigeria. Two hundred processors were sampled in four communities, using a multistage sampling procedure.

The majority of the processors were males (53.5 %), married (49.0 %), Christians (49.0 %), and with secondary education (22.0 %). Most respondents had knowledge that cassava waste could be sold to generate income (81.0 %), used to produce chemicals (78.5 %) and utilised as a source of energy (78.5 %). The major constraints to cassava waste utilisation included high cost of cassava waste processing (82.0 %) and the lack of processing equipment (82.0 %). The correlation analysis shows a significant correlation between the ages of respondents and cassava waste utilisation (r = −0.538 p < 0.05), years of education, and cassava waste utilisation (r = −0.073, p < 0.05). However, marital status (r = −0.087, p < 0.05) and income (r = −0.048, p < 0.05) had hypothesised a positive relationship with cassava waste utilisation, but not significant. The study concluded that the majority of the respondents had a positive attitude towards cassava waste utilisation, but were constrained by inadequate finance, lack of processing equipment, high cost of hired labour, and high cost of processing. The biogas properties of cassava waste have transformational potential in addressing energy poverty in developing economies like Nigeria.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"411 1","pages":"185 - 190"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76631273","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 was therefore conducted to evaluate the effect of mycorrhizal inoculation and compost made from Cocoa Pod Husk (CPH) and cattle dung in the bioremediation of Spent Engine Oil (SEO)-contaminated soil. About 2.5 kg of sterilised soil was contaminated with SEO at different concentrations: 0, 100, and 150 mL / pot. Compost was then added after two weeks of contamination at the rate of 10 g / pot. Inoculation for treatments containing Glomus mossaea (consisting of 20 g of root soil-fungal mixture) was blended into the soil samples as well. It was a 2 × 2 × 3 factorial experiment that was laid out in a completely randomised design and replicated three times. The incubation was allowed to last for twelve (12) weeks before the termination of the experiment. Data were collected on the Total Petroleum Hydrocarbon (TPH), bacterial and fungal biomass of the SEO-contaminated soil. Results obtained indicate that combined application of mycorrhiza with 100 mL / pot SEO resulted in significantly (p < 0.05) lower residual TPH content (54.50% degradation) of the contaminated soil compared to the other treatment combinations whereas significantly higher residual TPH content (20.43% degradation) of the contaminated soil was obtained from the interaction between 150 mL / pot SEO and without mycorrhizal inoculation. Interaction between mycorrhiza and 10 g / pot compost had a significantly higher bacterial colony (6.58 CFU / g) compared to other treatment combinations. Mycorrhizal inoculation resulted in a significantly higher fungal colony (5.844 CFU / g) compared with non-mycorrhizal inoculation (3.222 CFU / g). Therefore, it can be concluded that mycorrhizal inoculation and compost were effective in the bioremediation of SEO-impacted soil.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"86 1","pages":"119 - 132"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83431218","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}

The data collected from 300 students through a multi-stage smapling procedure were analysed using descriptive statistics and Quadratic Almost Ideal System model (QUAIDS). The results have shown that some of the price coefficients expectedly had a negative relationship with the expenditures. The youths also spent more on beans and chicken but spent less on groundnut. Furthermore, expenditure elasticities of all protein foods were positive. Moreover, expenditure elasticities for beans, eggs, beef and goat meat showed that they were necessities goods, whereas chicken, turkey, soy milk, pork, groundnut and milk were luxury goods. Both compensated and uncompensated elasticity showed that own-price elasticities for the selected protein food items were inelastic, with the exception of goat meat. Demand for protein foods was influenced by own-prices of the protein foods, prices of other protein foods and being a male student. In order to meet their daily dietary needs within a limited budget, students should substitute expensive protein sources like chicken, goat meat, beef and turkey with cheaper ones like groundnut, soymilk, beans and eggs in their diets.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"9 1","pages":"83 - 91"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76189455","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 was done to analyze the economics of snail production and to estimate its contribution to the food security of farming households in Oyo State, Nigeria. Primary data were obtained through the use of a structured questionnaire that was administered to the snail farmers. Based on the discovery of this work, the result shows that 39.2 % of the sampled farmers were within the active age bracket (41–50 years). 92.5 % of the farmers were males indicating men were actively involved. The majority of the farmers were literate with (83.3 %) having tertiary education. The mean farming experience was about 7 years with most of the farmers (47.5 %) having experience of 5–8 years. Most (86.7 %) of the respondents were married. The majority (40 %) engage in farming as an occupation primarily. The result showed that the returns to snail production were high (net profit ₦317.88/0.75 USD per jumbo-size snail). Every naira investment generated about ₦1.96/0.0046 USD. This demonstrated a high economic return of the snail farming business for boosting the revenue of the farming household. It was revealed that the cost of breeding stock, stocking density, and labour cost had a significant effect on revenue generated from snail production. Snail production was also not seen to have a significant contribution to the food security of farming households in the study area. The result further showed that the major constraints faced by snail farmers in the study area include lack of financial capacity for business expansion, unavailability of collaterals for loan acquisition to aid farm activities, and lack of inadequate extension visits among others. Hence, the study emphasizes the need for the government to invest heavily in snail production and encourage people to venture into snail farming business.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"46 1","pages":"159 - 168"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86976627","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}

Contract farming is one of the approaches employed to increase farmers’ productivity. However, agricultural outcomes have not been consistent with contract farming in developing countries. Hence, we examined the effect of contract farming on productivity of cassava farmers in Iseyin Local Government Area of Oyo State, Nigeria. Primary data were collected using a multi-stage procedure to select the farmers. Descriptive and econometric methods were employed for data analysis. The findings revealed that farm size and years of education of the participants in contract farming in the area were significantly different from non-participants by 0.45 ha and 1.76 years, respectively. Years of education, farm size, planting improved cassava variety, price of cassava output and being a female cassava farmer were significant drivers of participation. The mean productivity of the cassava farmers was about 0.89. Non-participants showed a higher productivity than their counterparts in contract farming. Although farm size increased productivity of cassava farmers, household size and contract farming significantly reduced it in the area. Hence, it was concluded that contract farming does not always significantly improve agricultural outcomes. Planting high-yielding varieties coupled with best agronomic practices will better address the issue of declining productivity of the cassava farms in the area, alongside reduction in family size. Further, giving considerable attention to favourable technical supports and contract terms will improve contract farming effect on agricultural outcomes.","PeriodicalId":7633,"journal":{"name":"Agricultura Tropica et Subtropica","volume":"44 1","pages":"65 - 73"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74946143","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}
