A field trial was conducted to determine the effects of different water conservation practices done in-situ on soil water content, stomatal conductance, and seed yield of common beans at Fumesua experimental station of the CSIR-Crops Research Institute in Ghana during the 2020 and 2021 cropping seasons. The water conservation practices implemented were tied ridges (TR), bunded basins (BB), and flat land (FL). Results showed that the TR treatment increased soil water content by 18 and 16% (0-5 cm), 12 and 13% (5-10 cm), and 18 and 7% (10-30 cm), compared with the FL treatment in 2020 and 2021 respectively. Across years, TR treatment increased stomatal conductance by 39 and 53% at both vegetative and flowering sampling periods. Soil water content and stomatal conductance also increased in the BB treatment compared to the FL treatment, but to a lesser extent than that of TR. The TR treatment improved seed yield by 31 and 42% over that of FL in 2020 and 2021, respectively. At a lesser magnitude, the BB treatment increased seed yield by 17 and 40% compared with the FL treatment during the same period. These results showed a positive relationship (p < 0.05) between the soil water content and common beans seed yield, such that an increase in soil water content determined about 75% of the increase in seed yield. Based on the results of this study, tied ridging could be considered a suitable water conservation strategy for improving common bean yield.

The study was conducted to determine the effect of diets containing different clay sources on the growth performance, heamatology and serum biochemistry of broiler chicks. One hundred and twenty broilers were allocated to five treatments diets containing different clay sources having three replicates of eight broilers in a completely randomized design. Data were collected on body weight, feed intake, total protein, albumin, glucose, total cholesterol, urea, low-density lipoprotein, high-density lipoprotein, triglyceride, aspartate transaminase and alanine transaminase, hemoglobin, red blood cell, white blood cell, lymphocytes, and packed cell volume. The total weight gain, average daily weight gain, total feed intake, average daily feed intake, feed conversion ratio and feed efficiency ratio were calculated. Results showed that growth performance parameters were not significantly (p > 0.05) different at the starter phase but serum biochemistry and haematological parameters except red blood cells were significantly (p < 0.05) different. The T3 diets containing clay formed by sprinter termites improved the serum biochemistry as well as haematological indices of broiler better than the other sources of clay used in this experiment. This implies that the clay in T3 had the greatest capacity to bind to the toxins contained in the feed probably due to the high mineral contents.

The properties of soils in an area are defined by the interaction between lithology and other factors of soil formation. Of the five factors of soil formation, climate is most important in the control of the distribution of crops in Nigeria, and oil palm is not an exception. The study was carried out to evaluate the suitability of land in Cross River State for oil palm production, and make appropriate soil management recommendations for improved production. Eight slope transitions were identified and two soil profile pits were sunk in each transition. Sixteen profile pits were used for the study. Currently, the well-drained high elevation soils are moderately suitable (S2) for oil palm cultivation; however, most of the well-drained soils in the higher elevation ranges in the southern agricultural zone are potentially highly suitable (S1). The central and southern agricultural zones are more suitable for oil palm cultivation. The poorly drained and low elevation areas in the three zones are not economical for the cultivation of oil palm and should be put to the cultivation of sugar cane and paddy rice.

This study carried out a comparative assessment of selected micronutrients under mixed tree plantation, cassava and secondary forest land use systems in Odighi, Edo State, Nigeria. The objectives of the study were to determine the concentrations of selected micronutrients under each of the three land use systems; evaluate the distribution of these micronutrients among the three land use systems; and examine the impact of the three land use systems on the selected micronutrients. Using transect sampling design, 18 soil samples were collected from each of the three land use systems giving a total of 54 soil samples for the study. The cassava land use was 7-10-year-old, mixed tree plantation was 10-15-year-old, while secondary forest was 25-year-old and above. Results showed that the concentrations of the selected soil micronutrients (iron, copper, manganese, and zinc) increased with increasing soil depth in all the examined sites except for manganese under cassava land use. The status of iron and zinc were rated excess while copper and manganese were rated optimum for crop production. The study observed significant (p < 0.05) variations for iron and manganese contents across the examined land uses and concluded that the direction and magnitude of changes in the status of micronutrients were a reflection of long-term impact of the different land uses and soil management measures. Liming of the soil and limited use of nitrogen-containing fertilizers are recommended to ameliorate zinc toxicity in the study area. Also, farmers in collaboration with agriculture extension workers should regulate the usage of organic and inorganic fertilizers as soil treatments to avoid excessive concentrations of iron and zinc in the study area.

The soils on Imo Clay Shale residua were sampled at Anaku and Igbariam in Anambra state, Nigeria to characterize, classify and evaluate their current suitability for rice production following standard scientific procedures. After several auger borings, modal profiles were sited, dug, described, and sampled. The soils generally belong to loamy textural classes or finer, especially in the subsoil layers. The morphological and physical properties of soils showed that the soils were poorly drained, favouring high water retention due to low hydraulic conductivity and slow permeability. All these conditions favour good rice performance. Though the soils contained high levels of exchangeable bases, exchangeable acidity was equally high leading to low base saturation (< 35%). Thus, the soils were classified as Typic Kanhaplaquults (Soil Taxonomy) and correlated to Gleyic Cambisols (World Reference Base for Soil Resources). Due to fertility inadequacies, the current suit- ability unit of the soils for rice production is suitability class 2 with fertility constraints (S2f). This implies that for sustainable rice production supplementary nutrients especially P2O5 from triple superphosphate or rock phosphate need to be applied. Based on the soil chemical results the following recommendations were made for optimum rice production: 100.00-120.00 kg ha‒1 urea, 60.00 kg ha‒1 P2O5 from triple superphosphate and 15.00 kg ha‒1 K2O (muriate of potash).

The supply gap of value-added products of yam and cassava in Nigeria has continued to widen and modeling investment in marketing of these products using Double Hurdle model is non-existence in literature. The study thus investigated factors influencing investment decision and level of investment in the marketing of valueadded products of yam and cassava in Benue State, Nigeria, using Double Hurdle model. Data were collected through structured questionnaire from 300 marketers of value-added products of yam and cassava, selected via multi-stage random sampling technique. The collected data were analyzed using descriptive statistics and Double Hurdle model. The results revealed that marketers of these products in the study area were mostly married females with moderate household size, literate, young, non-member of cooperatives, experienced, and had access to credit with akpu/fufu as the most marketed product among the marketers. Estimates of the Double Hurdle model revealed that sex, marital status, age, and membership of cooperatives were the factors influencing investment decision in the marketing of these products while sex, marital status, level of education, age, membership of cooperatives, return, and credit received were the factors influencing level of investment in the marketing of these products. In identifying factors that significantly influence investment decision and level of investment in the marketing of these products, this study provides an empirical contribution to the existing literature. It was recommended that policies geared towards increasing the level of investment in the marketing of these products should take into consideration the socio-economic characteristics of the marketers.

The study was conducted to assess Freundlich, Langmuir, and Temkin isotherm studies of silicon sorption of soils derived from three parent materials in Edo State, Nigeria. A completely randomized design was used to collect fifteen soil samples from five depths in three replications at three locations namely, NIFOR, Uhomora, and Ososo which are developed on Coastal Plain Sand, Imo Shale, and Basement complex rock parent materials respectively. Some soil physical and chemical properties were determined according to standard procedure, in the Faculty of Agriculture laboratory, University of Benin. Samples were equilibrated in 50 ml distilled water containing various amounts of Si as Calcium-Magnesium silicate (CaMgSiO2) to give 50, 100, 200, 400, and 800 mg Si L-1 for 30 min., allowed to stand overnight, equilibrated again for 30 minutes, filtered and Si read colorimetrically. Data obtained were fitted to Freundlich, Langmuir, and Temkin adsorption models. Results showed that the Temkin model expressed Si sorption capacity better considering the R2 values of 0.733, 0.296, and 0.288 for coastal plain sand, Imo shale, and Basement complex rock soils, respectively. The soils formed on Basement complex rock adsorbed more Si than soils formed on Coastal plain sand and Imo shale parent materials, considering the mean Temkin BT (retention capacity of adsorbed Si) values. The Temkin model could be relied upon as a suitable model to determine Si sorption in soils of the study area.
该研究的目的是评估Freundlich、Langmuir和Temkin对尼日利亚埃多州三种母质土壤硅吸附的等温研究。采用完全随机设计，在NIFOR、Uhomora和Ososo 3个地点，从5个深度3个重复采集15个土壤样品，分别发育在海岸平原砂、Imo页岩和基底复杂岩石母质上。根据标准程序在贝宁大学农学院实验室测定了一些土壤的物理和化学性质。样品在含有不同Si量的硅酸钙镁(CaMgSiO2)的50 ml蒸馏水中平衡，分别得到50、100、200、400和800 mg Si L-1 30分钟，静置过夜，再次平衡30分钟，过滤并比色读取Si。所得数据拟合Freundlich, Langmuir和Temkin吸附模型。结果表明，沿海平原砂、Imo页岩和基底复杂岩石土壤的R2分别为0.733、0.296和0.288,Temkin模型能更好地表达硅的吸附能力。考虑到吸附硅的平均Temkin BT值，基底复合岩上形成的土壤比沿海平原砂和伊莫页岩母质上形成的土壤对硅的吸附更多。Temkin模型可作为测定研究区土壤硅吸附的合适模型。

A clear understanding of soil characteristics and their appropriate classification are essential for efficient land use and increased productivity. The present study was carried out to obtain the fertility capability classification (FCC) of the soils overlying the basement complex in a toposequence in north eastern Nigeria and to serve as baseline data for soil management. Soils on four topographic positions identified on porphyritic granite (PG), pegmatite (PT) and granite-gneiss (GG) of the basement complex in Taraba State of Nigeria were assessed. Twelve pedons were studied in all, four along the toposequence on PG, PT, and GG. At the type and substrata type, sandy and loamy group dominated. Ustic soil moisture regime, exchange acidity (fixing available phosphorus) and low organic carbon limited the entire soils across the basement complexes restricting rainfed crop production to one season per annum except with irrigation practice. Poor drainage was a limitation across the soils on pegmatite. The FCC rated PG and GG soils as SLdeam (sand over loam and limited by moisture, effective cation exchange capacity, aluminium toxicity and organic carbon) and Ldam (loam type and substrata characteristics limited by moisture, aluminium toxicity and organic carbon), and PT and PT soils as Sdamg (sandy type and substrata type restricted by moisture, aluminium toxicity, organic carbon, drainage). Ridge construction, organic and mineral fertilizer applications are essential management practices required for sustainable use of these soils.

This study assessed the occupational hazards and injuries associated with frozen fish marketers in Abeokuta metropolis, Ogun State of Nigeria. A two-stage sampling procedure was adopted in sampling 150 fish marketers from 10 popular markets within the study area. Data were elicited with the aid of an interview schedule and analyzed using descriptive statistics such as frequency distribution, percentage, mean, standard deviation, and Pearson’s Product Moment Correlation (PPMC) analytical tools. Results obtained showed that the mean age of the fish marketers was 37.96±11.04 years, the majority were females (87.9%), married (83.2%), and had a mean household size of 9.00±4.00 persons. Also, 54.4% and 42.3% of the fish marketers had secondary and tertiary education, respectively. In terms of safety measures adopted, all the fish marketers used pain relievers after work, while higher proportions usually use hand gloves (76.5%), wear nose masks (86.6%), wear an apron (80.5%), use plaster in cases of cuts (53.7%) and do regular medical check-up (49.7%). Most (60.4%) of the fish marketers were found to be in good/safe working conditions, while more than half (53.0%) of them were exposed to a high level of hazard. A significant negative relationship existed between working conditions and the level of hazard experienced by the fish marketers (r = –0.721, p ≤ 0.01). It was concluded that occupational hazards are associated with frozen fish marketing. The study recommended that fish marketers should operate from shops to avoid dirty, dusty, and noisy environments to improve their working conditions.

A two-stage sampling procedure was adopted in sampling 150 fish marketers from 10 popular markets within the study area. Data were elicited with the aid of an interview schedule and analyzed using descriptive statistics such as frequency distribution, percentage, mean, standard deviation, and Pearson’s Product Moment Correlation (PPMC) analytical tools. Results obtained showed that the mean age of the fish marketers was 37.96±11.04 years, the majority were females (87.9%), married (83.2%), and had a mean household size of 9.00±4.00 persons. Also, 54.4% and 42.3% of the fish marketers had secondary and tertiary education, respectively. In terms of safety measures adopted, all the fish marketers used pain relievers after work, while higher proportions usually use hand gloves (76.5%), wear nose masks (86.6%), wear an apron (80.5%), use plaster in cases of cuts (53.7%) and do regular medical check-up (49.7%). Most (60.4%) of the fish marketers were found to be in good/safe working conditions, while more than half (53.0%) of them were exposed to a high level of hazard. A significant negative relationship existed between working conditions and the level of hazard experienced by the fish marketers (r = –0.721, p ≤ 0.01). It was concluded that occupational hazards are associated with frozen fish marketing. The study recommended that fish marketers should operate from shops to avoid dirty, dusty, and noisy environments to improve their working conditions.

There is virtually no information on the effects of artisanal sand mining on peri-urban agriculture in Nigeria in general and Osun State in particular. This study assessed the effects of sand mining on peri-urban agriculture in Ife East and Ife Central Local Government Areas of Osun State during 2015-2019. In effect, the study sought to identify and explain the rate and extent of changes in land uses in the study area, evaluate the level of encroachment of sand mining activities into other land use classifications, and examine socioeconomic factors that determined parting of land for sand mining by landowners in the study area between 2015 and 2019. Data were generated from both primary and secondary sources. Multi-stage sampling technique was used to collect primary data from 60 landowners, 30 cultivators and 30 residents giving a total of 120 respondents using structured questionnaire. Mean ages of landowners, farmers and residents were 67.9 years, 39.6 years and 47.3 years respectively. Majority (68.3%) of landowners had no formal education, while majority (73.3%) and (90%) of farmers and residents had formal education. Majority (68.3%) of landowners were farmers while majority (66.7%) and (76.7%) of farmers and residents were employees of governments. Majority (93.3%) of landowners were males, 100% of farmers were males. Cultivated land area decreased from 48% to 23.2% (–24.8%), built-up area increased from 37.3% to 41.8% (4.5%) while sand-mined area substantially increased from 14.6% to 35% (20.4%). Parting of land for sand mining increased with increasing age, household size and primary occupation being farming while parting of land for sand mining decreased with higher level of education. It is therefore recommended that all levels of government in the country should embark on close monitoring of land use to prevent frequent occurrence of land and environmental degradation. Additionally, Land Use Act of 1978 should be reviewed by bringing all stakeholders together to deliberate on how to prevent multiple land ownership and conflicts.
