Ochratoxin is one of the most frequently occurring mycotoxins in food and feed. In humans and animals, it is the cause of health disorders, mycotoxicosis. Monitoring the content of ochratoxin in food and feed is an important part of preventive measures. This work was focused at determining the concentrations of ochratoxin in complete feed mixtures for broilers and turkeys by ELISA analysis. The presence of ochratoxin in concentrations lower than 2 ppb was confirmed in the examined samples. The ochratoxin content limit for supplementary and complete feed mixtures for poultry, which represents a value of 100 ppb in feed with a moisture content of 12%, was not exceeded in the samples.

The objective of the study was the evaluation the effects of the peroral intake of humates (HS) added into feed mixtures on the energy metabolism of broiler chickens (Cobb 500). The selected parameters are concentrations of glucose, triglycerides and cholesterol analysed in the blood serum. There were used four groups of birds (A, B, C, negative control; n=120) in the experiment. Chickens were fed with ground diets (starter HYD1, grower HYD2, finisher HYD3) with supplements of HS from day 1 to 37 as follows A: Humac nature (HN) 7 g/kg, B: Humac nature monogastric (HNM) 7 g/kg, C: HNM 5 g/kg feed (Humac Ltd., Slovak Republic). The diets had the following content of crude protein: HYD1 230.20, HYD2 222.20, HYD3 209.40 g CP /kg dry matter). The statistical evaluation of results was performed by one-way analysis of variance and means were compared by the Student-Newman-Keuls test and correlation analysis. Higher concentrations (P<0.05) of triglycerides in blood serum were analyzed in groups A or B by 0.24 and 0.26 mmol/l, respectively, in comparison to the control group (y = 0.35830x + 0.58324). The values of cholesterol were at a lower level (P<0.05) in all 3 experimental groups by 1.07, 0.54 and 0.84 mmol/l (y = - 1.18073x + 2.75772). The positive effect of the intake of HS on glucose concentration was not confirmed when a higher concentration (P<0.05) was analyzed in the blood serum of the control group compared with groups A or C by 3.31 and 4.56 mmol/l (y = - 4.06420x + 13.37519), respectively.

It´s necessary to make visible the characteristics of the existing dairy systems in the province of Chaco, although it isn´t taken into account in the statistics. The objective of the work was to identify the adoption of technology in different groups of producers of dairy establishments in the center-west of the province of Chaco-Argentina. Visits were identified and made to 14 dairy establishments between September 2021 and July 2022. The drums were divided into three groups: dairy farm group of agricultural schools (GEA) with mechanical milking, group of dairy farms with only one milking per day (G1O) with manual milking and the group of dairy farms with two milkings per day (G2O) with mechanical milking. The medium and ranges were obtained. The number of cows in milking was 13 (4-24), 7 (12-15) y 14.5 (7-20) (p>0.05). The hectares dedicated to milk production of 18 (13-69), 45 (25-247) and 30 (20-235) hectares (p>0.05), the use of rotation within the lots, 66%, 57% and 100% apply technology. The age at first pregnancy was 24 (24-36), 24 (24-36) and 27 (24-36) months (p>0.05), the duration of breastfeeding in days, 210 (210-300), 180 (150-240) and 205 (200-210) days (p>0.05). The well-marked differences appear in the presence of floor and cement roof in the milking place that only the establishments of two milking possess it. The three groups perform hands hygiene before starting milking and nipple washing before the start of the milking. However, only GEA is the one that performs the sealing of the nipples at the end of the milking. The groups of producers of dairy establishments in the center-west of the province of Chaco-Argentina, which make two milking per day showed a greater adoption of technology in the social aspects and the milking routine. However, we must continue working and that forces the need to generate care policies.

In the present study, the levels of Total Phenols compounds (TPC) and the antioxidant capacity of different extracts from leaves of Cassytha filiformis (C. filiformis), Commiphora schlechteri (C. schlechterii), Ochna natalitias (O. natalitia) and Pavetta assimilis (P. assimilis) were evaluated by the Folin-Ciocalteu and ferric ion reduction methods, respectively. The extracts evaluated were prepared with solvents of different polarities (n-hexane, dichloromethane, ethyl acetate and aqueous methanol). The total phenols found in all samples increase with solvent polarity. The reduction power found was linearly proportional to the concentration and is greater the greater the content of total phenolics. All extracts of the species O. natalitia (DCM, EtAcO and MetOH) showed higher antioxidant capacity than the other species. Thus, the promising results found in the present study suggest a high potential of these species as a source for the development of therapeutically useful natural antioxidants.

The study conducted content analysis of indigenous and national newspapers (NP) published between 2014 and 2015 with respect to agricultural information disseminated to stakeholders in agriculture. Both purposive and stratified sampling technique was used to select Akede and Alaroye as the indigenous and the Nation and Punch as NPs because of their popularity and coverage in Nigeria. A total of 384 newspapers were used for this study. Results showed that the newspapers featured less of agricultural related information despite the fact that the available agricultural information was carried in form of hard news (5.7% and 81.7%), features (7.3% and 91.7%), photography (4.7% and 50.0%), opinion issues (2.1% and 64.1%), and advertisement (1.6% and 56.2%) for indigenous language and national newspapers respectively. Also, information such as employment in agriculture-related (4.7% and 52.6%), health issues related to agriculture (6.2% and 53.1%), crop production (5.7% and 52.1%), animal husbandry (4.7% and 51.6%)for indigenous language and national newspapers respectively among others were the commonly featured news. Only 6.8% and 80.2% of the indigenous and National newspapers allotted column inches ranging from 0.00-7.0 to agriculture. About 6,8% and 60.4% and 4.7% and 58.9% of indigenous language and national NPs targeted the general audience and Male farmer for disseminating agricultural information. Significant difference existed in the agriculture information featured between the indigenous and national newspapers with an F-test value of 44.882 at p= 0.01; indicating that national newspapers featured agricultural news more than the indigenous ones. It was recorded that limited space was allocated to the few available information on agriculture in the sampled newspapers. It was concluded that agricultural news were not adequately disseminated in the dailies especially the local dailies that farmers mostly have access to. It was recommended that agriculture-related information should be published on the platforms where the target audience can access for effective communication

This study examines sustainable agricultural development in the Mekong Delta, Vietnam by focusing on technology improvement for minimizing the environmental load in rice production with sufficient yield and quality. Among rice-producing countries, Vietnam is the third-largest rice export country worldwide. High-yield rice production is still a critical issue in Vietnam. However, in recent years, quality improvement and low environmental load agriculture have been fundamental issues. In this research, we conducted rice cultivation experiments in 2014, 2015, and 2017 under different conditions of planting density, fertilizer volume, rice variety, use of fertilizer applicator mounted on a transplanter, and use of high-density seedling mat called “Mitsunae.” We conducted 7 seasons with 79 planting patterns in experiments to compare yield, quality, and fertilizer volume in rice production. As a result of productivity achievement, high-density transplanting does not always produce a high yield. Each performance depends on transplanting density, rice variety, fertilizer volume, or other factors. In general, transplanting machine with a planting width of 25cm achieved a significant yield with short growing duration rice varieties. Those varieties are popular in the Mekong Delta. We conducted experiments of “high-density seedling mat” called “Mitsunae”, a new nursery technology developed in Japan, to reduce the environmental load and operating costs in rice production. With the “Mitsunae” method, we can reduce the number of rice seedling trays up to three times that of conventional seedling mats. Then, we can minimize the nursery surface area, nursery materials, and total working time, including transplanting time. The “life cycle assessment (LCA)” method is practical for correctly quantifying environmental load reduction. We investigated environmental load reduction caused by “Mitsunae” rice nursery process using LCA method in this research. We could achieve about 20% – 30% reduction of the “greenhouse gas (GHG)” emission volume and economic benefits created by the “Mitsunae” nursery process.

This study was designed to analyze the effects of agricultural extension services on leaf vegetables farmers’ use of agro-chemicals in Imo State, Nigeria. The study described socioeconomic characteristics of leaf vegetables farmers that use agro-chemicals, ascertained the role of extension services on use of agro-chemicals by leaf vegetable farmers, ascertained the sources of information on the use of agro-chemicals among leaf vegetable farmers, determined the influence of extension services on agro-chemicals use by leaf vegetable farmers and determined the extension variables influencing use of agro-chemicals by leaf vegetables farmers. Data were collected in 2021 with structured and validated questionnaire from 128 proportionately and randomly selected leaf vegetables farmers that use agro-chemicals in Imo State. Data were analyzed using descriptive statistics such as mean, frequency distribution and percentages as well as econometric tools of bivariate and logit regression models. Major roles of extension services in farmers’ use of agro-chemicals for leaf vegetables production were acting as catalyst to speed up adoption rate, technology transfer and source of information. The major sources of information to the leaf vegetables farmers on agro-chemicals use were fellow farmers association and traders on vegetables. Extension services positively and significantly influenced leaf vegetables farmers’ use of agro-chemicals. The agricultural extension variables influencing use of agro-chemicals by leaf vegetables farmers were availability of certain communication media, extension agents familiarity, relevance of subject matter, size of extension staff, size of audience, frequency of use of familiar teaching methods, farmers’ satisfaction with extension information, perceived usefulness of extension information, perceived quality of extension staff and relative cost of the extension teaching methods. There is need for extension services to intensify efforts at visiting and training leaf vegetable farmers on the appropriate application techniques of agro-chemicals to their vegetables to minimize the hazardous effects of the agro-chemicals on farmers’ health and the environment and consequently increase productivity and farm income. Keywords: Extension services, leaf vegetables, farmers, agro-chemicals, Imo State.

Chronic food insecurity is one of the main problems, which affected millions of Ethiopians for centuries. To solve the food insecurity problem and move away from the previous system of annual emergency appeals, the Ethiopian government in collaboration with development partners launched social protection program called productive safety net program. This study evaluated the impacts of productive safety net program on household poverty alleviation, by measuring the wellbeing of rural households using outcome indicators of the program i.e. calorie intake, consumption expenditure and livestock asset using cross-sectional survey data collected from 200 households in ECC-SDCOH facilitated kebeles of productive safety net program in eastern Ethiopia. Multistage stage sampling technique was used to randomly select representative household heads. Both primary and secondary data were analyzed using descriptive and econometric statistics. Applying a propensity score matching technique, the study found that the program has significantly increased participating households’ calorie intake by 30% (i.e., 856 calories), the consumption expenditure by 2.84% and livestock asset by 40% compared to that of non-participating households. The results of the logit model also indicated that program participation is significantly influenced by family size, education, marital status, dependency ratio, size of land holding and credit use. Therefore, to reduce poverty level of the country, due attention has to be given by the program to reducing gender disparity in poverty and sustained effort is needed to government-administered productive safety net program districts to accelerate the rate of poverty reduction. And the program should consider roles of significant variables in the selection of participant households for the desired impact under related locations.

It is possible to produce efficiently in areas that are considered inadequate, as long as all the technologies are not transferred from the temperate zones in which the most important dairy basins of the country are located. The objective of the work was to identify and productively characterize the dairy farms in the center-west of the province of Chaco - Argentina. 11 dairy farms were identified and visits were made between September 2021 and April 2022 located in the center-west of the province of Chaco. The results show that the median and age ranges of the owners surveyed was 47 (36-67) years old, the area used for milk production was 50 (20-275) hectares, of which 78% is natural forest and 22% are dedicated to the production of cultivated pastures. The median and ranges of the milking cows were 9 (2-20) cows and 12 (3-15) dry cows, total milk production per day: in warm months 30 (14-300) liters and in cold months 30 (6-300) liters, the duration of lactation 200 (150-270) days. Dairy farms in the center-west of the Chaco province were identified and characterized, showing that there is dairy production in the region and that this forces the need to generate attention policies for them.

This study is conducted to evaluate the performance of semi-mounted potato planter (two row with a cup), on an area of (50 x 8 m) in the farm of the College of Agricultural Studies-Sudan University of Science and Technology. The effects of three levels of soil penetration resistance (100-70kg/cm2, 70-45kg/cm2 and 45-25kg/cm2) on the performance of potato planter was evaluated in terms of the seed to seed spacing, percentage of missing seed , depth of planting and field capacity. The results revealed that the increase in the soil penetration resistance induced a significant decrease in the depth of planting, Also There is no significant different between the two higher and medium levels of soil resistance (100-70kg/cm2 and 70-45kg/cm2), for seed to seed spacing, while there are a significant different in the lower level (24-45 kg/cm2). In contrast the levels of soil resistance did not show significant differences in the percentage of missing seed At the recommended soil resistance the effective field capacity and field efficiency of the planter was about 0.20 ha/hr and 63%, respectively. The developed polynomial relations between the studied evaluations attribute soil penetration resistance can be used to predict the field attribute to implement for certain soil penetration resistance
本研究旨在评估苏丹科技大学农业研究学院农场面积为（50 x 8m）的半挂式马铃薯播种机（两排带杯）的性能。从种间距、缺种率、种植深度和田间持力等方面评价了不同土壤渗透阻力水平（100-70kg/cm2、70-45kg/cm2和45-25kg/cm2）对马铃薯播种机性能的影响。结果表明，土壤渗透阻力的增加导致种植深度的显著降低。此外，土壤阻力的两个较高和中等水平（100-70kg/cm2和70-45kg/cm2）在种子间距方面没有显著差异，而在较低水平（24-45mg/cm2）则有显著差异。相反，土壤阻力水平在种子缺失百分比方面没有显示出显著差异。在推荐的土壤阻力下，播种机的有效田间容量和田间效率分别约为0.20公顷/小时和63%。所研究的评估属性与土壤渗透阻力之间的多项式关系可用于预测特定土壤渗透阻力的现场属性
