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.

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.

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.\u0000  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.\u0000  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.\u0000  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.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43105354","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}

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.","PeriodicalId":92332,"journal":{"name":"Asian journal of agriculture and food science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46287977","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}
