The purpose of this study was to examine saltwater recreational anglers’ answers to the fifteen statements regarding the importance of fishing trips, and to classify groups exhibiting common patterns of responses from individuals’ recreational fishing motivations using the data extracted from the database collected from the 2013 National Saltwater Angler Survey. 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.
本研究的目的是检查咸水休闲垂钓者对关于钓鱼旅行重要性的15个陈述的回答,并使用从2013年全国咸水垂钓者调查收集的数据库中提取的数据,对个人休闲垂钓动机表现出共同反应模式的群体进行分类。利用因子分析,这15个陈述被简化为五个维度,分别是捕获、信息、站点偏好、社会和管理。基于k-means聚类分析的实证结果确定了三个不同的咸水休闲垂钓者群体,命名为捕获和社会,地点选择和钓鱼相关群体。判别分析结果表明,聚类均值差异显著。利用多层感知器神经网络模型作为预测模型,根据休闲垂钓动机对咸水垂钓者进行分类。从建筑的角度来看,它展示了一个15-9-3神经网络结构。本研究可能为了解存在何种类型的咸水娱乐愤怒群体提供信息,并在数据集中识别未知群体,以用于咸水娱乐钓鱼的规划和管理目的。

This study was conducted to identify the socioeconomic characteristics of Transplant Aman (T. 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.

Tea is a major plantation crop and the socioeconomic pillar of Terai region of West Bengal. Use of various inorganic fertilizers may have increased the crop production but affected the environment badly. Importance of biomass of different trees in accumulation of carbon had long been known but few studies on characterization of biomass accumulation are reported. So, selection of different species for getting the good amount of organic nutrients is important. In tea plantation, various leguminous trees are used as shade trees. This research, conducted in the tea plantation of University of North Bengal, has provided some approaches which could possibly reduce the application of inorganic fertilizers. Different tests on physicochemical parameters, micronutrients status, biomass etc. were conducted with the collected plant litters. The results of this comparative analysis suggested and validated the beneficial effects of each shade tree in organically maintaining nutrient profile of tea plantation soil.
茶叶是西孟加拉邦德莱地区的主要种植作物和社会经济支柱。使用各种无机肥料可以提高作物产量,但对环境影响严重。不同树种生物量在碳积累中的重要性早已为人所知,但关于生物量积累特性的研究却很少。因此,选择不同的物种以获得适量的有机营养是很重要的。在茶园中,各种豆科树木被用作遮荫树。本研究在北孟加拉大学茶园进行,提供了一些可能减少无机肥料施用的方法。对收集的凋落物进行理化参数、微量元素状态、生物量等试验。对比分析结果提示并验证了各遮荫树种在有机维持茶园土壤养分剖面方面的有益作用。

Sweet potato is a food and nutrition security crop in sub-Saharan Africa with low yields resulting from soil infertility. 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. Results of the study showed that FC, PL/NPK20-10-10 and RHB/NPK20-10-10 were the most promising soil fertility amendments to boost sweet potato productivity in the Nitisols and Andosols.
甘薯是撒哈拉以南非洲的一种粮食和营养安全作物,由于土壤不孕症,产量低。研究了9种施肥制度对两个以安土和硝土土壤为特征的农业生态区橙肉甘薯和白肉甘薯品种生长性能的影响。处理分别为:NPK20-10-10、NPK6-15-28、稻壳生物炭(RHB)、快速堆肥(FC)、石斛叶粉、家禽凋落物(PL)、RHB/NPK20-10-10、FC/NPK20-10-10和PL/NPK20-10-10。这些与不施肥的对照进行了比较。Andosol和Nitisol土壤呈酸性,全氮、有机碳、C/N、磷、钾、钙、镁含量差异显著(p < 0.05)。肥料效应对不定根、总产量和市场产量的影响最大,对主茎长和收获指数的影响较小,对枝数、叶柄长和叶面积指数的影响较小。土壤类型和甘薯品种对主茎长和甘薯喜度影响较大。品种×肥料对不定根形成影响较大,土壤×品种×肥料对总产量和商品量均有影响。在土土中,OFSP的LAI、一手枝数、干生物量、总产量和可售产量最好,而WFSP的主茎长、叶柄长、不定根和HI最好。结果表明,FC、PL/NPK20-10-10和RHB/NPK20-10-10是在硝壤和安土土壤中最有希望提高甘薯产量的土壤肥力改良剂。

The main objective of this research article is to analyze the impact of the production of some major crops, namely rice, jute, wheat, sugarcane, and potato on the agriculture sector in Bangladesh. 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.
本研究文章的主要目的是分析一些主要作物的生产,即水稻,黄麻,小麦,甘蔗和马铃薯对孟加拉国农业部门的影响。农业部门被认为是孟加拉国经济的一个重要部门,它提供了国内生产总值(GDP)的很大一部分。本研究使用了1988-2017年的年度时间序列数据。采用了几种计量经济学技术来检验数据,包括增广的Dickey-Fuller (ADF)检验、Johansen协整检验和普通最小二乘(OLS)方法。为了验证模型,进行了残差诊断检验,即正态性检验、异方差检验、序列相关性检验和稳定性诊断检验。研究结果表明,模型中存在两个协整方程。此外,小麦和黄麻生产对农业部门都有重大的积极影响。虽然水稻和马铃薯生产对农业部门的影响是积极的,但在5%或10%的显著性水平上,这些影响并不显著。另一方面,甘蔗生产对农业部门产生了重大的负面影响,这是没有预料到的。基于研究结果,本文建议孟加拉国政府应重点设计和实施新的资助政策和补贴,以改善甘蔗行业的增长、生产和发展。最后,政府应该关注与气候变化有关的因素,这些因素会对孟加拉国的作物生产产生负面影响。

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.

The experiment was conducted to evaluate the performance of dhap residue and nutrient sources on the growth and yield of red amaranth, radish and garlic during the period from October, 2013 to February 2014 and October, 2014 to February 2015 at Gopalganj district in Bangladesh. The single factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. There were eight treatments viz. control (without organic and inorganic fertilizer), cowdung, recommended dose of NPK, 50% cowdung + 50% recommended dose of NPK, dhap residue, dhap residue + cowdung, dhap residue + recommended dose of NPK, dhap residue +50% cowdung +50% recommended dose of NPK. Dhap residue significantly influences the growth and yield of all three crops i.e red amaranth, radish and garlic. In respect of red amaranth, the tallest plant (43.70 cm and 42.37 cm, respectively) and maximum number of leaves (33.00 and 33.33, respectively) per plant as well as yield (20.88 and 21.32 t ha-1, respectively) were observed from dhap residue + 50% cow dung + 50% recommended dose of NPK which was significantly similar to dhap residue + recommended dose of NPK in both the years. Similar results were also observed in radish for root growth and in bulb production of garlic. From economic consideration, the application of dhap residue + 50% cow dung + 50% recommended dose of NPK fertilizers were suitable for growth and yield as well as cost effective for red amaranth, radish and garlic production under the climatic conditions in Gopalganj district of Bangladesh.
本试验于2013年10月至2014年2月和2014年10月至2015年2月在孟加拉国Gopalganj地区进行,研究了磷渣和营养源对红苋菜、萝卜和大蒜生长和产量的影响。单因素试验采用随机完全区组设计(RCBD), 3个重复。对照(不施有机肥和无机肥)、牛粪、NPK推荐用量、50%牛粪+50% NPK推荐用量、牛粪渣、牛粪+牛粪、牛粪+ NPK推荐用量、牛粪+50%牛粪+50% NPK推荐用量8个处理。甲磷残留量对红苋菜、萝卜和大蒜三种作物的生长和产量均有显著影响。在红苋菜中,甲磷渣+ 50%牛粪+ 50%氮磷钾推荐用量的植株最高(分别为43.70 cm和42.37 cm),单株最大叶数(分别为33.00和33.33),产量(分别为20.88和21.32 t hm -1),与甲磷渣+氮磷钾推荐用量在两年内显著相似。在萝卜的根生长和大蒜的球茎生产中也观察到类似的结果。从经济角度考虑,在孟加拉国Gopalganj地区的气候条件下,施用草甘膦渣+ 50%牛粪+ 50%推荐用量的氮磷钾肥适合红苋菜、萝卜和大蒜的生长和产量,且具有成本效益。

Association of sustainability agriculture and farming practices is somehow closely connected. There are necessary different farming practices for both adjusted and unadjusted PFSI measurement. The study observes practices of paddy farming and if farmers are practicing agriculture sustainably by estimating PFSI in three villages of Gutudia union. The objective is to spot the present agricultural practices and accessible sustainable practices, to examine the sustainability degree at field beneath the present paddy farming systems using PFSI and additionally to identify recommendations. The unit of analysis is 50 farmers and measured on a scale of 0 to 100 and also through Saltiel, Bauder, and Palakovich (1994) index. The results discovers that the average sustainability level which is presumably quite unsustainable this shows the necessity for more extension of correct practices. Chi-square analysis shows that the level of farmers’ awareness toward sustainable agriculture and positive attitude are considerably different with the level of PFSI.
可持续农业协会和农业实践在某种程度上是密切相关的。调整和未调整的PFSI测量有必要不同的耕作方式。该研究通过估算Gutudia联盟三个村庄的PFSI,观察了水田种植的做法,以及农民是否在可持续地从事农业生产。目的是找出目前的农业做法和可获得的可持续做法,使用PFSI检查目前水田耕作系统下农田的可持续性程度,并确定建议。分析单位为50名农民,并以0到100的等级测量,也通过Saltiel, Bauder, and Palakovich(1994)指数进行测量。结果发现,平均可持续性水平,这可能是相当不可持续的,这表明需要更多的扩展正确的做法。卡方分析显示,农户对可持续农业的认知水平和积极态度水平与PFSI水平存在显著差异。

Effect of Land Use and Slope Position on Infiltration Characteristics on Sandstone-Derived Soils of Southern Nigeria 土地利用方式和坡位对尼日利亚南部砂岩土入渗特性的影响
Pub Date : 2021-05-24 DOI: 10.18488/JOURNAL.70.2021.83.122.133

A study of some soil properties that influence infiltration under different land use types and slope positions in sandstone-derived soils was carried out in Akwa Ibom State, Southern Nigeria. 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.
在尼日利亚南部的阿夸伊博姆州进行了一项研究,研究了在不同土地利用类型和斜坡位置下影响砂岩土入渗的一些土壤特性。土壤样品一式三份进行实验室分析,采用双环渗透计法进行入渗试验。采用方差分析、相关分析和回归分析对数据进行了评价,结果表明:油棕种植和休耕增加了连续耕地土壤有机质含量,降低了容重,增加了土壤孔隙度和团聚体稳定性。下坡土壤运动导致上坡的粘土和有机质流失到中下坡土壤中。初始入渗速率、最终入渗速率、累积入渗速率、吸收率和透过率在不同研究地点间差异较大,但受土地利用方式、坡位及其相互作用的影响不显著(P≤0.05)。油棕地和休耕地各坡位土壤的入渗速率均明显高于连作地,其粘土含量、总孔隙度、平均重径、饱和导水率和有机质含量均明显高于连作地。较重的有机质输入将有助于改善上部坡面土壤,增加入渗速率。研究区泥泞地形应采用人工林农业,不提倡连作,以增加水分入渗。贡献/独创性:本研究是为数不多的研究土地利用和坡位对入渗特性的综合影响的研究之一,研究表明,与连续耕作导致裸露的上坡相比,植被覆盖的土地入渗倾向于向坡位下部增加。
