Therefore, the present study was undertaken to acquire documentation for a database of the composition of selected minor fruits. The total phenolic (TPH), vitamin C, total carotene, and ß-carotene contents and antioxidant activity of selected minor fruits were determined by 1,1-diphenyl-2picryl hydrazyl (DPPH) scavenging and reducing power assays (RPA). Phenolic compounds were assessed using high-performance liquid chromatography coupled with a photodiode array detector and autosampler. Results revealed that minor fruits contain different phytochemicals, particularly TPH, ascorbic acid, total flavonoid (TF), ß-carotene, total carotenoid (TC), and total anthocyanin content (TAC); values ranged, respectively, 0.23-176.50 mg GAE/g, 16.67-664.92 mg/100 g, 2.26-150.02 mg QE/100 g, 1.41-6897.57 µg/100 g, 1.26-98.24 mg/100 g and 1.15-47.46 mg/100 g. In the parameters antioxidant activity, total antioxidant capacity, DPPH, reducing power capacity (RPC), ferric reducing antioxidant power (FRAP), metal chelating capacity (MCC), nitric oxide (NO), and free radical scavenging activity, IC50 ranged 0.01-278.24 µg of ascorbic acid/mg of extract, 39.70-250.00%, 3.21-634.00%, 0.02-1817.88 µM Fe2SO4/100g, 22.29-210.43%, 0.02-70.50%, and 4.98-856.70 µg/g, respectively. Among the identified and quantified phenolic acids, leading examples were gallic acid (279.06 mg/100 g), vanilic acid (43.77 mg/100 g), Þ-courmaric acid (178.96 mg/100 g), ferulic acid (20.44 mg/100 g), and lutein (91.13 µg/100 g) in aonla, day fruit, elephant apple, and bilimbi. Moreover, all selected minor fruits are rich sources of bioactive, biochemical, and antioxidant compounds with potential for use in therapeutic applications.","PeriodicalId":36876,"journal":{"name":"Asian Journal of Agriculture and Rural Development","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90499690","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}

Substantial amounts of diverted irrigation water are often lost because of poor water control, inefficient irrigation conveyance systems, poor on-farm water management, or poor application practices. Field experiments were conducted on three farm plots within the command area for water availability and accessibility under the Melka Hida small-scale irrigation scheme in the West Guji Zone of Oromia Region, Ethiopia. The physical characteristics of soil, including depth, particle distribution, textural classification, bulk density, field capacity, and permanent wilting point, were studied and the results are presented. Furrow parameters including slope, width, length, and shape geometry were measured. The cumulative infiltration and infiltration rates were also recorded. The results show that irrigation application efficiency ranged from 57 to 64% with an average of 61%, indicating that about 40% of the applied water was not used by crops. The storage efficiency ranged from 79.6 to 81.6% with an average of 80%. Soil moisture measurements showed that crops were water stressed during the experimental period. Application efficiency decreased with increasingly steep slopes and cutoff times, greater applied depth, and high inflow rate in the study area. Unavailability of irrigation water control structure, weakness of water users’ associations, and maintenance of furrows and steep slopes were observed as the major causes of inefficient water management in the Melka Hida irrigation scheme.","PeriodicalId":36876,"journal":{"name":"Asian Journal of Agriculture and Rural Development","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88790443","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}

Over a 2-month period of data collection (eight weekend visits) a total of 255 consumers were interviewed on site at the time of purchase, from whom we collected 235 completed questionnaires. Consumers in the sample were divided into three clusters and were rated positively on all seven factors considered. The findings of the study are that in cluster 1, about 80% of consumers were willing to pay more at the farmers’ market rather than to go to a nearby retail outlet or supermarket. Cluster 2 comprised those consumers who prefer value for money while cluster 3 includes those consumers who gave a high rating to the hygiene and service conditions at the market.

This implies that rice production needs attention. The existence of inefficiencies in lowland rice production could reduce rice yields for consumption, so the measurement of technical efficiency in lowland rice production needed to be studied. This research aimed to analyze the level of technical efficiency in lowland rice cultivation and identify the factors affecting it. The research was done in the Palolo and Torue subdistrict of Indonesia. The number of samples used was 249 lowland rice farmlands, consisting of 106 and 143 farmers of organic and inorganic lowland rice cultivation, respectively. The results show that land, fertilizer, seeds, and labor had a positive and significant effect on lowland rice production. The average technical efficiency of lowland rice cultivation was around 78.2%. The results also show that manager education, extension contacts, superior seeds, and organic lowland rice cultivation have a significant effect on the level of technical efficiency in lowland rice production. We concluded that there is an opportunity for farmers to increase lowland rice yields if they can manage production factors in an efficient manner. The government could provide support for farmers, such as formal and informal education, extension, superior seeds, and ready-to-use organic materials.","PeriodicalId":36876,"journal":{"name":"Asian Journal of Agriculture and Rural Development","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91019919","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}

Cow size influences biological efficiency of individual animals, which influences herd composition and stock flow on a predetermined resource base. This in turn influences the economic efficiency of the herd. Individual cows were classified as either small, medium, or large and their individual biological efficiency determined. When similar reproduction and growth rates were assumed, large cows were the most biologically efficient, followed by medium and small cows. Income from the herd of small cattle was the lowest, as fewer kilograms of beef were available to sell. Allocated costs for the herd of small cattle were the highest, due to a large number of expenses being charged per head of cattle. Subsequently, when economic efficiency was calculated, the herd of large cattle was more profitable than its smaller counterparts. The herd of large and medium cattle would become less profitable than the herd of small cattle at lower reproduction rates, and these reproduction rates were calculated. Smaller cattle have a faster maturity rate than larger cattle. A faster maturity rate provides the opportunity for early breeding. The effect of limiting feed intake of small, medium, and large cattle was compared and yielded varying results. The study concluded that cattle size influences biological efficiency, biological efficiency influences economic efficiency however there are many more variables that influence biological and economic efficiency other than size, such as reproduction rates.","PeriodicalId":36876,"journal":{"name":"Asian Journal of Agriculture and Rural Development","volume":"450 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86785846","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}
