Combining ability for marketable sweet potato root yield were carried out using ten sweet potato varieties and their F1 hybrids in Cylasformicarius endemic (Landmark University, Omu Aran) and free (University of Ibadan) environments during 2012 cropping season. Both general combining ability and specific combining ability play significant role on traits such as marketable root yield, non- marketable root yield, and total number of storage root/plant and marketable storage root, root size, percentage of tuber damage and weight of total roots, as well as the incidence and severity were generally low, suggesting the role of additive and dominant gene action in tolerances to Cylasformicarius. Hybrids from the parents Resisto, TIS 87/0087 displayed high performance in term of Cylasformicarius tolerance. These parents and their hybrids appeared to have gene pools for Cylasformicarius tolerance that can be manipulated for developing promising hybrids in South west, Nigeria.

This study evaluated the profitability analysis of small-scale fishing along coastal areas of Ondo State, Nigeria. Structured questionnaire was used to collect data from 400 small-scale fishermen which were selected via multi-stage sampling procedure. Data collected was analyzed using descriptive statistics and profitability indicators. Results revealed that mean age of respondents was 39 years, among the fixed assets for fishing, outboard engine has the largest percentage cost (88.32%) while among variable assets, fuel has the largest percentage cost (67.16%). Profitability indicators such as Benefit Cost Ratio (BCR) 1.29, Gross margin ₦1,261,476.60k/fisherman/year, Return on Investment (ROI) 0.29, Net Profit Margin (NPM) 0.23 and Gross Revenue Ratio (GRR) 0.77 were used to estimate the profitability of small-scale fishing. The findings further revealed that fishing boat (1.284), outboard engine (0.352), fishing nets (1.342) and fuel (0.193) were positively and statistically significant at p<0.05 level with fish output level while accessories (floats, sinks and hooks) (0.142) was positively and statistically significant at p<0.1 with fish output level. The R2 value was 72.1% showing that the independent variable was well explained by the exogenous variables. Problems encountered by small-scale fishermen include inadequate infrastructural facilities, poor road networking system and inadequate credit facilities. Based on the findings, it was recommended that small-scale fishermen should organize themselves into cooperatives in order to increase their credit accessibility. Likewise, government should embark on construction of good road network in order to ease transportation of fish harvested to the neighboring towns.

A study was carried out to investigate the comparative morphology and pH of the gut in the Giant African Land Snails, in Archachatina marginata and Achatina achatina respectively. The crop is long, distended and less fleshy with reddish brown coloured juice (5.8 ml volume) in A. marginata, while it is short, compact and fleshy with greenish brown coloured juice (3.2 ml volume) in A. achatina. The digestive gland was heavier (17.36 vs. 15.74 g) in the latter than the former. The absolute weight of the crop in A. marginata was significantly (p<0.05) higher than in A. Achatina, however, the absolute and relative weights of the digestive gland in A. achatina was significantly (p<0.05) higher than in A. marginata. There were significant (p<0.05) differences in linear measurements of the salivary gland and crop for absolute values and the salivary gland, crop, stomach and digestive gland for relative values. Archachatina marginata had significantly (p<0.05) longer salivary gland and crop than Achatina achatina for absolute length values and significantly (p<0.05) longer salivary gland, crop and digestive gland for relative length values. However, the relative stomach length in A. achatina was significantly (p<0.05) longer than in A. marginata. The gut pH was more acidic in the crop (5.38 and 4.83) than in the mouth (6.93 and 6.82) where it tended towards neutrality in A. marginata and A. achatina respectively. The pH profiles in the two species, decreased by 1.65 and 1.99 from the mouth to the crop while it increased by 1.46 and 1.97 from the crop to the distal digestive gland in A. marginata and A. achatina respectively. In the herbivorous snails, the pH along the gut regions remained acidic all through (5.38 – 6.93 and 4.83 – 6.82) in A. marginata and A. achatina respectively, confirming the herbivorous habits in these snail species. The longer gut and distended crop with higher volume of crop juice in A. marginata, implies its ability to store, utilize and digest more food materials than A. achatina. These results provide the basis for a better understanding of the physiology of the digestive processes in these snails.

Finessing the question on household settlement choice is to enquire the income/consumption expenditure distribution that either makes her better-off or worse-off. Using 430 household-level micro-data from a three-stage sampling procedure, the study ranked consumption expenditure by household attributes in Delta state, Nigeria on axiomatic poverty measure. Results showed that household heads in the widowed and 0<𝑎𝑔𝑒≤20 years categories in Delta-North first-order stochastically dominated Delta-South (𝑁≻𝑠=1𝑆), 20<𝑎𝑔𝑒≤40 years household heads in 𝑆≻𝑠=1𝐶 and 𝑁≻𝑠=1𝐶, household heads in the widowed, vocational education holder and 0<𝑎𝑔𝑒≤20 years, 20<𝑎𝑔𝑒≤40 years and 𝑎𝑔𝑒>60 years categories in 𝑁≻𝑠=1𝐶, while household heads in the vocational education holder, 0<𝑎𝑔𝑒≤20 years, 20<𝑎𝑔𝑒≤40 years and 𝑎𝑔𝑒>60 years categories in 𝑆≻𝑠=1𝐶. Household heads in the female, single, medium household-size, tertiary education holder and 0<𝑎𝑔𝑒≤20 years categories in 𝑁≻𝑠=2𝑆 and 𝑁≻𝑠=3𝑆. Household heads in the single, medium-size, 20<𝑎𝑔𝑒≤40 years and tertiary education holder categories in 𝑁≻𝑠=2𝐶 and 𝑁≻𝑠=3𝐶. Household heads in the separated spouse and small household-size categories in 𝐶≻𝑠=2𝑁 and 𝐶≻𝑠=3𝑁 while household heads that are in the single category in 𝐶≻𝑠=2𝑆 and 𝐶≻𝑠=3𝑆. There is, generally, no stochastic dominance between pairwise comparisons by district in the state, in terms of consumption expenditure, except by other household attributes.

The risk associated with the presence of heavy metals in soil is their potential toxicity and ability to enter the ecosystem through the food chain. Total heavy metal content of a soil is inadequate for predicting the toxicity of heavy metals in soil. Therefore, the current study was designed to determine the various forms in which the selected heavy metals: Chromium (Cr), Lead (Pb), Nickel (Ni), and Cadmium (Cd) exist in the soil to ascertain the available forms for plant uptake. Soils samples were randomly collected from selected organic and conventional farms in Akinyele local government, Ibadan, Oyo State, Nigeria, at different depths (0-15, 15-30 and 30-45 cm) using random sampling method. Routine analysis was carried out to determine the textural classes and chemical properties of soil samples. The total heavy metals of the soil samples were determined and their fractions were analysed using sequential extraction method. Cadmium was not detected in most of the soil samples. Residual fraction was predominant in all the analysed heavy metals. In addition, Cr was more associated with the oxidizable fraction having a range of 0.1 mg/kg from Ajibode organic farm (AO) at 30-45 cm depth. Pb and Ni were both more associated with reducible fraction with Pb having a range of 2.7 mg/kg in Ajibode conventional farm (AI) at 0-15 cm depth and 0.1 mg/kg in (AI) at 30-45 cm depth. Reducible values of Ni ranges from 4.3 mg/kg in AI at 0-15 cm to 1.4 mg/kg in AO at 30-45 cm. The apparent mobility and bioavailability for these heavy metals in the studied soils were in the order: Pb>Cr>Ni. The result showed that uptake of heavy metals by the plants would be low as the concentration of the exchangeable form of the heavy metals in the analysed soil sample has the least concentration when compared with the other forms.

Gender is one of the key issues of discourse among policy experts, research scholars and government as part of the sustainable development goals. In this paper, we examined gender roles in food security among farming households in Kogi state, Nigeria. First, we assessed the food security status of the farm households. Second, the contributions of gender in household security status were identified. A three-stage sampling technique was used to select 120 farm households and data were collected using a well-structured questionnaire. In the study we employed the use of food security index, chi square test and logistic regression analysis. The results revealed that only about 35% of the households are food secure (>2470 kcal/AE/day). The logistic regression model shows that fitted model is statistically significant with the log likelihood of 118.691 and Chi-square of 59.19 (P value < 0.05) with the R2 of 0.61. Household size, access to credit and membership of social groups are significant factors influencing households’ food security status. Therefore, the study recommends that women empowerments should be inculcated into the mainstream of any government policy targeted at ensuring food security of rural households.

This research was conducted to analyse the economics of improved groundnut seeds’ production in North-Western, Nigeria. A multi-stage sampling technique was employed for this study. Data were collected from 125 producers of improved variety of groundnut seeds in Bunkure Local Government Area (LGA) of Kano State using well-structured questionnaire. The data collected were analysed using both descriptive and inferential statistics. The descriptive statistics result revealed that respondents were active, mostly males and that they were mostly literate. The result revealed that the marketing of improved variety of groundnut seeds was efficient and that the enterprise was considered viable. Age, household size, farm size and access to credit were the factors that influenced the net marketing margin to producers of improved groundnut seeds. The study recommends that adequate credit facilities should be made available and improved variety of groundnut seeds should be subsidized so that producers can be motivated to use and adopt them.

Redents and their ectoparasites populations are key components of animal production farms production in Egypt and all over the world. However, their population dynamics and the factors affecting their abundance are still not well understood. The seasonal variations during the activity periods of Rattus rattus frugivorous and Rattus norvegicus, and their associated ectoparasites with three weather factors i.e., maximum biweekly mean temperature, minimum biweekly mean temperature as well as biweekly mean relative humidity as significant drivers of the rodent and their associated ectoparasites presence were recorded. Results showed that the biweekly fluctuations of weather factors seem to be mostly a reaction wards condition in altering the activity of both the rodents and their associated ectoparasites. Both species had three periods of activity in the two years of study and four and five periods of activity of the ectoparasites on R. rattus frugivorous and R. norvegicus. The highest biweekly variation in rodent's population was observed on the date 12 March and 10th September for the two species respectively. Also, a significant positive and negative correlation between the climatic conditions and the population activity of the two rodents and their ectoparasites is dependent on the periods of the activity. The combined effect of the three weather factors on the fluctuation of population activity of the two species of rodents was ranged from 78.9 to 98.03% and from 55.31 to 99.11% for R. rattus frugivorous and R. norvegicus during the three periods of activity through the two years of study. The simultaneous effect of the three tested weather factors on the fluctuation of population activity of rodents and their ectoparasites were varied through periods of activity. The temperature and relative humidity were two key factors that influenced the seasonal fluctuation of rodents and ectoparasites.

However, their population dynamics and the factors affecting their abundance are still not well understood. The seasonal variations during the activity periods of Rattus rattus frugivorous and Rattus norvegicus, and their associated ectoparasites with three weather factors i.e., maximum biweekly mean temperature, minimum biweekly mean temperature as well as biweekly mean relative humidity as significant drivers of the rodent and their associated ectoparasites presence were recorded. Results showed that the biweekly fluctuations of weather factors seem to be mostly a reaction wards condition in altering the activity of both the rodents and their associated ectoparasites. Both species had three periods of activity in the two years of study and four and five periods of activity of the ectoparasites on R. rattus frugivorous and R. norvegicus. The highest biweekly variation in rodent's population was observed on the date 12 March and 10th September for the two species respectively. Also, a significant positive and negative correlation between the climatic conditions and the population activity of the two rodents and their ectoparasites is dependent on the periods of the activity. The combined effect of the three weather factors on the fluctuation of population activity of the two species of rodents was ranged from 78.9 to 98.03% and from 55.31 to 99.11% for R. rattus frugivorous and R. norvegicus during the three periods of activity through the two years of study.

Many researchers worldwide have suggested the use of cement kiln dust (CKD) as a soil amendment and a source of nutrients to enhance crop performance. Pot experiment was accomplished in the greenhouse of Soil Science Department, Faculty of Agriculture, Minia University, to investigate impacts of white and black CKDs applied at six rates (0, 4, 8, 12, 16, and 20 g kg -1 ) to sandy loam soil on some soil chemical and biological properties and maize growth and quality parameters. Treated soils with either white CKD or black CKD were very slightly saline; moderately alkaline; and still in a safe lead, nickel, and cadmium levels. Soil amendment by increasing white CKD rate from 0.0 up to 16 g kg -1 increased microbial biomass C and N and enzyme activity of arginase and β-glucosidase. The highest values of plant height, fresh and dry weight of maize plants, and water use productivity by maize plants were recorded with 16 g kg -1 of white CKD. There was no distinct accumulation of lead, nickel, and cadmium in the maize shoots. It is applicable to use white CKD only at the application rate of 16 g kg -1 (16 Mg feddan -1 ) for crops grown in sandy soils under conditions of El-Minia Governorate, Egypt.
世界各地的许多研究人员都建议使用水泥窑粉尘作为土壤改良剂和养分来源来提高作物生产性能。通过盆栽试验，研究了白色和黑色ckd分别以0、4、8、12、16和20 g kg -1 6种剂量施用于砂壤土对土壤化学生物学特性和玉米生长品质参数的影响。白色或黑色CKD处理过的土壤都是非常轻微的盐碱化;适度的碱性;铅，镍和镉的含量仍然是安全的。将白色CKD速率从0.0提高到16 g kg -1，土壤改良可提高微生物生物量C、N和精氨酸酶和β-葡萄糖苷酶的酶活性。在16 g kg -1白色CKD处理下，玉米植株株高、鲜重、干重和水分利用效率最高。玉米幼芽中铅、镍、镉的积累不明显。在埃及El-Minia省的沙质土壤条件下，白色氯喹只适用于16 g kg -1 (16 Mg feddan -1)的施用量。
