Plant based adsorbents have attracted a great attention as ecofriendly and low-cost adsorbent. The goal of this study was to prepare adsorbent from Terminalia arjuna bark using chemicals named hydrochloride followed by sodium hydroxide for lead ions removal. \u0000Study Design: The research is experimental in nature. \u0000Place and Duration of Study: This research was conducted in Department of Chemistry and Biochemistry at CCSHAU, Hisar in year 2022-23. \u0000Methodology: The functionality, surface morphology, and elemental analysis of that biosorbent was analysed by FTIR, FE-SEM with EDX respectively. The bark samples were treated with 400 mL of 0.1 M hydrochloride and 400 mL of 0.01 M sodium hydroxide, respectively, before being used as an adsorbent. Batch studies were done for biosorption of heavy metal ions. The maximum biosorption capacity of lead ions were optimized by varying the pH (2-8), lead ions concentration (10- 100 mg/L), biosorbent dose (0.01-0.04 g/50mL), and contact time (10–60 minutes). \u0000Results: The maximum removal efficiency of about 71% was obtained at 6 pH having 0.03g of biosorbent at 27⁰C for 60 minutes. The Freundlich adsorption isotherms and pseudo first order kinetics models were the most suitable for the biosorption of lead ions and the maximum adsorption capacity was 125 mgg-1 at optimized time 60 minutes. \u0000Conclusion: The finding indicated that Terminalia arjuna bark based biosorbents would potentially be an inexpensive and environment friendly for lead ions removal from water environment.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141273268","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}

Utilizing a Randomized Block Design (RBD) with eight treatments replicated three times, the study aimed to investigate the impact of spacing levels on cocoa yield traits. The treatments involved in the experiment included a double row of cocoa planted between two rows of coconut trees, with spacing configurations as follows: T1 (3m x 1.2m), T2 (3m x 2m), T3 (3m x 2.5m), and T4 (3m x 3m). Additionally, a single row of cocoa between two coconut rows was examined, with spacings represented by T5 (1.5m), T6 (2m), T7 (2.5m), and T8 (3m). Results revealed significant variations among spacing treatments, with cocoa at 3m spacing demonstrating the highest productivity, yielding 43.47 pods per tree and 1021.48 g of dry beans per tree. Noteworthy findings included T1 (3m x 1.2m) exhibiting the longest pods (16.64 cm), T6 (2m) the widest pod girth (21.67 cm), and T8 (3m) producing the heaviest pods (204.50 g). Additionally, T6 yielded the highest total beans per pod (37.34) and dry bean weight (25.44 g), T4 had the heaviest single fresh bean (1.63 g), and T2 demonstrated the highest single dry bean weight (0.70 g). These findings offer valuable insights for optimizing cocoa cultivation practices, emphasizing the importance of spacing configurations in maximizing yield and bean characteristics.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141102709","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}

Heritability estimates ranged from 22.61% (Primary branches plant-1) to 89.35% (Days to maturity) for different traits, emphasizing the potential for selection in breeding programs. Positive correlations were observed among various traits in both progeny generations, providing insights into the interplay of genetic factors influencing pigeon pea traits.

The total area under flower crops during 2023-24 was 285,000 hectares; production of loose flowers was estimated to be 21.52 lakh metric tons, and cut-flowers were 645 metric tons. Both fresh and dried cut flowers lead floriculture exports from India. (NHB, 2023-24). Among the plethora of flowers, the rose stands out as a plant with hundreds of species and thousands of cultivars, many of which are native to Asia. These roses are not only extensively used in commercial perfumery and pharmaceuticals but also as commercial cut flower crops. In the current era of commercialization, rose cultivation has expanded to both protected and open-field methods. Therefore, this study was undertaken to analyze the Comparative Analysis of Open vs. Protected Cut Flower Rose Farming in Karnataka. The study was based on primary data collected from 40 farmers each from both the districts, namely Chikkaballapura and Bengaluru Rural. \u0000The data were analysed using cost and return analysis and capital budgeting techniques. The results obtained from this study indicated that the cultivation of roses was profitable under open and protected fields. But comparatively, the rate of return obtained from protected cultivation was higher, i.e., 54 per cent with a 1.58 B:C ratio, than open-field cultivation, i.e., 47 per cent with a 1.21 B:C ratio. Therefore, efforts should be made to educate the traditional rose farmers to adopt a better package of practices followed by protected farms and encourage them by providing cheaper institutional credit and subsidies.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"13 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141118602","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 long memory behavior of series is investigated by the ACF plot and Hurst R/S analysis. A fractionally integrated autoregressive moving-average (ARssFIMA) model is fitted using 668 weekly data (January 2009-November 2022). This study shows the efficiencies of the Hurst exponent, GPH, Smoothed periodogram, Local Whittle, and Wavelet methods used to estimate the fractional difference parameter in the ARFIMA model. Furthermore, we compared the forecasting abilities of the ARFIMA and ARIMA models. The results show that long memory is present in the jute price series. The models selected according to each method are ARFIMA (3,0.348,0), ARFIMA (3,0.291,1), ARFIMA (2,0.487,0), ARFIMA (3,0.461,0), ARFIMA (2,0.311,0), and ARIMA (2,1,1) on the basis of minimum AIC and BIC using 534 in-sample data. Finally, the wavelet method based ARFIMA (2,0.311,0) model is found to be the best optimal model in terms of MAE, RMSE, and MAPE criteria using 134 out-of-sample data. A comparative study indicates that the forecasting performance of the ARFIMA model is strongly better than that of the ARIMA model in this regard.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"104 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141115832","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}
