Natural products have gained substantial consideration in correcting diabetes and its associated level globally. This research is conducted to access the therapeutic potential of turmeric and black cumin to lessen the diet related malfunctioning like diabetes mellitus which is defined by elevated blood glucose level. Turmeric and black cumin both possess disease prevention properties like anti-diabetic, anti-hyperlipidemic, antioxidants and numerous others. Therapeutic effect of turmeric and black cumin was assessed by an efficacy study on streptozotocin induced diabetic rats. Rats were divided into 5 groups that are G0 consist of healthy rats, G1 consist of diabetic rats without giving any treatment, G2 involves diabetic rats received turmeric powder, G3 involves diabetic rats received black cumin powder and G4 consist of diabetic rats treated with combined mixture of turmeric powder and black powder. The objective of this study was to estimate the anti-diabetic role of turmeric and black cumin in rats. The result indicated that blood glucose level and serum lipid profile was greatly improved by combined mixture of turmeric and black cumin rather than the individual doses of turmeric and black cumin. Thus the result showed that turmeric and black cumin has potential to treat diabetes mellitus and related disorders.","PeriodicalId":19826,"journal":{"name":"Pesquisa Agropecuaria Brasileira","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81467725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ber fruit is known as “fruit of poor” because of low price in the market. This work was planned to evaluate Aloe vera gel and olive oil edible coating to enhance its shelf life and minimize post-harvest losses. The treatments included were T1= (control), T2= Olive oil (2%), T3= Olive oil (2.5%), T4= Olive oil (3%), T5 = Aloe vera gel (2%), T6 = Aloe vera gel (2.5%) and T7= Aloe vera gel (3%). Physico-chemical parameters of fruits were analyzed and recorded 12 day of storage. The study revealed that both olive oil and Aloe vera gel coatings were effective in maintaining quality of Ber fruit during storage period of 12 days. Minimum physiological weight loss, lesser loss in acid contents were observed in Aloe vera gel treated fruits along with maximum color retention compared to uncoated fruits. Coatings delayed ripening. Ascorbic acid loss and decay percentage were reduced by using different concentrations of olive oil and Aloe vera gel. Based on results deduced from the present study, it is concluded that application of Aloe vera gel was at par with olive oil coating but olive oil 3% and Aloe vera 3% proved best so, these coatings could be applied to enhance fruit shelf life and quality.","PeriodicalId":19826,"journal":{"name":"Pesquisa Agropecuaria Brasileira","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78750622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Daily evapotranspiration was determined with constant water table lysimeters, with water replacement by a drip system. As a source of Si, silicon oxide was applied three times in the crop cycle - at the initial, intermediate, and final development stages of the plant. At the end of the cycle, samples of plant tissue (root, stem, leaves, and inflorescence) and soil were collected to determine Si by spectrometry. The Si content in the soil was not influenced by water replacement, only by silicate fertilization. The silicon applied to the soil increased the content of the element in the plant components, especially in the roots.
