Results indicated significant variation among the varieties. Based on the results of the 1st year multi-location trial, seven superior ones were selected for further testing in AYT and RYT in next two years. In the SYT, varieties Farida and 7four7 were the highest yielders. In the AYT, the highest average yield over location was also produced by 7four7 (38.70 t/ha). Varieties Cimega and Memphis also gave comparable yields to that of 7four7 (37.33 and 36.67 t/ha, respectively). Considering the yield of the three generations, the above four varieties were significantly better than the checks. Considering the specific qualities, Farida was found most suitable for table purpose because of its high yield, medium-sized oval and smooth tubers with good eating quality. The variety Taisiya produced tubers with good size and shape, but low in dry matter content; so not suitable for processing. Memphis might be selected for French fry as it produces maximum large sized tubers with good long oval shape. On the other hand, variety Panamera is a high yielder but its plant type was undesirable. On the whole, varieties Cimega, 7four7 and Farida are suitable for table purpose, and Memphis may be selected for French fry under Bangladesh condition. None was found quite suitable for Chips preparation.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43038344","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}

The goal of this study was to explore if alpha-mangostin (a common secondary metabolite) could be detected in mangosteen pericarp phytochemical fingerprints and how much of it could be represented using a standard calibration curve. The antioxidant activity has been touted as a primary active ingredient in many commercial goods, including cosmetics and food supplements. To test for the antioxidant reaction to the DPPH onto the TLC plate, mangosteen pericarps were obtained from 12 orchards that were grown without pesticides in Cha-Uat (CU), Lan Saka (LS), and Phrom Khiri (PK) districts of Nakhon Si Thammarat. The samples were dried and powdered before being extracted with methanol using the reflux technique. After that, the TLC was utilized to determine the phytochemical fingerprint. The quality of phytochemicals from the LS orchards was found to differ from CU and PK samples, with different bands of compounds at RF 0.2, 0.25, and 0.57. The average amount of alpha-mangostin in the 12 samples was not statistically different, according to a one-way analysis of variance with a p-value of 0.05. The average range of interest (ROI) intensity area of the antioxidant was investigated using a one-way analysis of variance with a p-value of 0.05 and repeated comparisons across the sample groups by Tukeys multiple comparison test.

Due to its polyphagous characteristic with a large host range, strong migration ability, high fecundity (average egg production per female is about 1500) and lack of diapause has already contributed to its invasiveness in America and Africa. Recently it has been introduced in Asia in the year 2018. Though it has been only around three years of Fall armyworm (FAW) introduction, it has already spread into many Asian countries and on the way to cause havoc. Though it can infest many crops, its main target and maximum yield loss has occurred in case of Maize. In America and Africa, farmers are already well known to this pest and have adapted themselves to reduce crop loss to some extent by undertaking several management options. As this pest is completely new to Asia, farmers do not know much about its biology, nature of damage and control measures. And their misdiagnosis of the pest leads to panic and increased crop loss. Therefore, it is very important to increase awareness among the farmers to identify its attack on the right time to take suitable control measures as well as preventive measures for upcoming cropping seasons. Some of the cultural, mechanical, biological and chemical control measures those were effective in reducing its infestation outside Asia, has also found to be effective inside Asia. Collaboration of these control measures according to the field condition is main concern for the cultivators. But the integrated pest management option alone can also help to keep FAW population much below economic injury level and prevent its invasiveness as a tool of sustainable management for ensuring food security.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48763287","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}

This study investigated innovative practices emanating from collaboration between support organisations/groups and farmers. Also, the question on how these practices influence the sustainability of organic farming was answered. A cross-sectional explorative research design was applied to collect data through semi-structured questions using interviews and focus groups in Bavaria and Baden-Wuerttemberg federal states, Germany. Innovative practices were performed at three key organisational levels namely; compliance with organic farming standards; production processes as well as marketing and consumer engagement. The findings revealed that collaborative innovative practices by support organisations/groups at the market and consumer engagement level was greater compared to other levels. The importance of innovative practices varied across the four dimensions (environmental, social, political, and economic) of organic farming sustainability.

However, due to high soil cooling load, growing these crops on tropical lowland area is a challenge except through greenhouse farming or on few cool higher altitudes with resemblance of temperate climate. Greenhouse farming involves cooling the entire volume of planting zone and is energy intensive, while few cool highlands are not sufficient to achieve food security in this direction. This study aims at application of chilled water for direct cooling of soil, to create favorable soil conditions for optimal performance of planted temperate crops. However, soil cooling using vapour compression refrigeration system may not be economically viable. Solar thermal chilled water production system is presented in this study to supply the cooling. The system consists of absorption refrigeration system and dimensioned size of soil bed with chilled water pipe network. The study includes modeling of soil cooling load to determine the refrigeration power required to overcome such load. The modeled system matched well with the experiment; having standard deviation of 1.75 and percentage error of 12.24%. Parametric analysis of the soil cooling showed that temperatures of cooled soil were significantly affected by chilled water flow rates. The regression equation developed from the Analysis of Variance (ANOVA) is suitable for predicting cooled soil temperature. The cooling process is technically feasible, with potential for greenhouse gas emission reduction.","PeriodicalId":53052,"journal":{"name":"Malaysian Journal of Sustainable Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41684859","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}
