Using the factor analysis, the fifteen statements were reduced into five dimensions, named catch, information, site preferences, social, and management. Empirical results based on the k-means clustering analysis identified three different saltwater recreational angler groups, named catch and social, site choice, and fishing related groups. Results of the discriminant analysis indicated that cluster means were significantly different. The multilayer perceptron neural network model was utilized as a predictive model in deciding the classification of saltwater anglers based on recreational fishing motivations. From an architectural perspective, it showed a 15-9-3 neural network construction. This study may provide insight into the information about what types of saltwater recreational anger groups exist and identifying unknown groups in the data set for saltwater recreational fishing planning and management purposes.","PeriodicalId":147153,"journal":{"name":"International Journal of Sustainable Agricultural Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126661139","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}

Aman) rice producers, compare the profitability of modern and traditional varieties and, analyze the factors affecting the production of modern and traditional T. Aman rice varieties. The multistage sampling procedure was used for selecting 60 farmers from Muktagacha, Ishworgonj and, Fulbaria Upazila under the Mymensingh district of Bangladesh. A semi-structured interview schedule was used for the purpose of collecting primary data. Tabular analysis, undiscounted BCR and, Cobb-Douglas production model were used for analyzing the data. The major findings of the study were that about 43.34% of the respondents belonged to the age between 46-65 years, 71.67% were male, 41.67% had primary education only, agriculture was the main occupation of 75% of the respondents and 53.33% had access to credit. The per acre average net return was Tk 16760.71 with a BCR of 1.47. The comparative analysis revealed that the per acre average net return and BCR of modern variety of T. Aman were Tk 23737.98 and 1.68 and of traditional variety of T. Aman were Tk 10601.58 and 1.27, respectively. The results of Cobb-Douglas production model showed that human labor cost, Urea cost, Boron cost, seed cost, pesticides cost, threshing and, drying cost had significant effects on the production of the modern variety. The findings of this study suggest that the production of the modern variety of T. Aman will be profitable which in turn will contribute to ensuring food security among the rural poor.","PeriodicalId":147153,"journal":{"name":"International Journal of Sustainable Agricultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129864552","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}

We examined the effects of nine fertilizer regimes on the growth performance of orange-fleshed (OFSP) and white-fleshed (WFSP) sweet potato varieties in two agro-ecological zones characterized by Andosol and Nitisol soils. The treatments were: NPK20-10-10, NPK6-15-28, rice husk biochar (RHB), fast compost (FC), Tithonia diversifolia leaf powder, poultry litter (PL), RHB/NPK20-10-10, FC/NPK20-10-10 and PL/NPK20-10-10. These were compared to a control of no fertilizer. The Andosol and Nitisol soils were acidic with significant differences (p < 0.05) in total nitrogen, organic carbon, C/N ratio, phosphorus, potassium, calcium and magnesium. Fertilizer effects were dominant on the adventitious root, total and marketable yields, moderately affecting main stem length and harvest index (HI) with weak effects on branch number, petiole length and leaf area index (LAI). Soil type and sweet potato variety strongly affected main stem length and HI. Variety × fertilizer strongly influenced adventitious root formation, while soil × variety × fertilizer affected total and marketable yields. LAI, primary branch number, dry biomass, total and marketable yields were best for the OFSP in the Andosol, while main stem length, petiole length, adventitious roots and HI were best for the WFSP in the Nitisol.

The agriculture sector is considered an important sector of the Bangladeshi economy, which supplies a significant proportion of the gross domestic product (GDP). Annual time-series data for the period 1988–2017 is used for the study. Several econometric techniques are employed to examine the data, including the augmented Dickey-Fuller (ADF) test, Johansen cointegration test, and ordinary least squares (OLS) method. To validate the model, some residual diagnostic tests, namely a normality test, heteroskedasticity test, serial correlation test, and stability diagnostic test are conducted. The findings of the study demonstrate that there are two cointegrating equations in the model. Furthermore, both wheat and jute production have a significant positive impact on the agriculture sector. Although the impacts of rice and potato production on the agriculture sector are positive, these are not significant at the 5 or 10 percent significance level. On the other hand, sugarcane production has a negative and significant impact on the agriculture sector, which was not expected. Based on the results, this paper recommends that the government of Bangladesh should focus on designing and implementing new funding policies and subsidies to improve the growth, production, and development of the sugarcane sector. Finally, the government should be concerned about climate change-related factors that negatively affect crop production in Bangladesh.","PeriodicalId":147153,"journal":{"name":"International Journal of Sustainable Agricultural Research","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116204264","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}

Soil samples were collected in triplicate for laboratory analyses and infiltration tests were conducted using the double ring infiltrometer method. Analysis of variance, correlation and regression analyses were used to assess the data Oil Palm Plantation and Fallow Land increased the organic matter content of the soil, reduced bulk density, increased the soil porosity and aggregate stability over Continuously Cultivated Land. Downslope soil movement caused the upper slopes to lose their clay and organic matter to the middle and lower slope soils. Initial infiltration rate, final infiltration rate, cumulative infiltration, sorptivity and transmissivity varied highly across the studied locations but were not significantly (P ≤ 0.05) affected by land use, slope position and their interactions. Apparently higher infiltration rates were observed in all slope positions under Oil Palm Plantation and Fallow Land as a result of their apparently higher clay contents, total porosity, mean weight diameter, saturated hydraulic conductivity and organic matter contents over those of Continuously Cultivated Land. Heavier organic matter input will help to modify the upper slope soils for increased infiltration rates. Plantation agriculture should be adopted and continuous cultivation discouraged to increase water infiltration on sloppy terrains of the study area. Contribution/Originality: This study is one of very few studies which have investigated the combined effect of land use and slope position on infiltration characteristics and has demonstrated that infiltration tend to increase towards the lower slope position of vegetated lands compared to upper slopes rendered bare by continuous cultivation.","PeriodicalId":147153,"journal":{"name":"International Journal of Sustainable Agricultural Research","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124276860","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}
