In the realm of plant breeding, genetic diversity stands as a pivotal factor for advancing crop improvement initiatives. Morphological characterization assists as a critical role, allowing for the scrutiny of discernible traits in crop plants as this facilitates the identification, classification, and comprehension of genetic variations present among diverse genotypes. The objective of this investigation was to scrutinize the morphological traits of 71 chickpea genotypes, with a particular emphasis on 10 selected qualitative traits, in adherence to the DUS testing guidelines. The experimental design employed was the randomized complete block design (RCBD) with three replications at the Research Farm, Department of Genetics & Plant Breeding, College of Agriculture, RVSVV, Gwalior, Madhya Pradesh, India during Rabi 2021-22. Among the parameters investigated, three exhibited a consistent dimorphic phenotype, six displayed three distinct phenotypes (trimorphic), and only one trait manifested more than three phenotypic variations (polymorphic). The diverse chickpea genotypes showed a substantial amount of genetic variability, demonstrating the potential for assigning distinct morphological profiles for varietal identification and characterization. Remarkably, for traits such as the foliage and flower color and seed shape, a high level of diversity within the chickpea genotypes was investigated employing Shannon's diversity indices. This comprehensive morphological characterization not only contributes to the understanding of the genetic landscape of chickpea genotypes but also provides valuable insights for varietal identification and selection in breeding programmes in future.
在植物育种领域,遗传多样性是推进作物改良计划的关键因素。形态表征作为一个关键的角色,有助于审查作物植物的可识别性状,因为这有助于识别、分类和理解不同基因型之间存在的遗传变异。本研究的目的是仔细检查71个鹰嘴豆基因型的形态性状,特别强调10个选择的定性性状,遵守DUS检测指南。实验设计采用随机完全区组设计(RCBD),在遗传学系研究农场进行3个重复;植物育种,农业学院,RVSVV,瓜廖尔,中央邦,印度拉比期间2021-22。在调查的参数中,3个性状表现出一致的二态表型,6个性状表现出三种不同的表型(三态),只有1个性状表现出三种以上的表型变异(多态)。不同的鹰嘴豆基因型表现出大量的遗传变异,证明了为品种鉴定和鉴定分配不同形态特征的潜力。在叶、花颜色和种子形状等性状上,Shannon多样性指数显示了鹰嘴豆基因型间的高度多样性。这种全面的形态特征不仅有助于了解鹰嘴豆基因型的遗传景观,而且为今后的品种鉴定和育种计划提供有价值的见解。

This study is intended to provide reliable and context-specific forecasting methodologies to support sustainable agricultural planning, resource allocation and policy formulation for the coconut industry in Kerala. It evaluates ARIMA models for Kerala’s coconut production area, production, and productivity. The ARIMA (0, 2, 1) model is preferred for the area of coconut production due to the precision of its residual statistics and the normality of its residual plots. The best fit for production and productivity is provided by the polynomial regression model of orders 3 and 9, respectively, which has lower MAPE, RMSE, and higher R2 values than ARIMA models. The hybrid model, which was created using the best-fitting polynomial and ARIMA models, provides a more accurate representation of the data than either the corresponding polynomial or ARIMA model due to its high R2 and low MAPE values. The hybrid models for area, production, and productivity have MAPE and R2 values of 1.78, 3.56, 3.01, and 0.9799, 0.9664, and 0.9395, respectively.
本研究旨在为喀拉拉邦椰子产业的可持续农业规划、资源配置和政策制定提供可靠和具体的预测方法。它评估了喀拉拉邦椰子生产面积、产量和生产率的ARIMA模型。由于残差统计量的精度和残差样地的正态性,ARIMA(0,2,1)模型更适合于椰子生产区域。3阶和9阶多项式回归模型对产量和生产率的拟合效果最佳,其MAPE、RMSE和R2值均低于ARIMA模型。使用最佳拟合多项式和ARIMA模型创建的混合模型,由于其高R2和低MAPE值,因此比相应的多项式或ARIMA模型提供了更准确的数据表示。面积、产量和生产力混合模型的MAPE和R2分别为1.78、3.56、3.01和0.9799、0.9664和0.9395。

Watershed morphological and hydrological properties can be derived from the drainage morphometric parameter. Morphometric analysis with the help of remote sensing and GIS techniques is considered to be the most useful approach for prioritization of watersheds. The main aim of the study is to evaluate the morphometric parameters of Kantori nala milli watershed located at Mahasamund district of Chhattisgarh state, India. This study outlines the significance of digital elevation model for assessment of drainage pattern and extraction of relative parameters. Milli watershed was automatically delineated and divided into eleven micro watersheds MWS 1 to MWS 11 on the basis of topography from the Depression less Digital Elevation Model (DEM) with 10 m resolution prepared by Inverse Distance Weighted (IDW) interpolation technique. Stream order in study area milli watershed ranges from one to two. Each parameter has been assigned their ranks according to their value. Thereafter, an average value of the rank score for each of the micro watershed is calculated. The micro watershed with the lowest compound factor (Cp) was given the highest prioritized rank out of the group of micro watersheds, and vice versa. The result from the priority ranking of morphometric analysis shows that MWS 7 is having high priority while MWS 8 is having low priority. Micro watersheds MWS 9 and MWS 11 falls under same priority i.e. 6 and also micro watersheds MWS 2 and MWS 4 falls under same priority i.e. 7. To control soil erosion, various land rehabilitation programmes and bioengineering methods should be adopted on the micro watershed of high priority categories, followed by medium and low priority categories.
流域形态计量参数可以推导出流域的形态和水文特性。在遥感和地理信息系统技术的帮助下,形态计量学分析被认为是确定流域优先次序的最有用的方法。本研究的主要目的是评估位于印度恰蒂斯加尔邦Mahasamund地区的Kantori nala milli流域的形态计量参数。本文概述了数字高程模型在流域格局评价和相关参数提取中的重要意义。利用反距离加权(IDW)插值技术制备的10 m分辨率的DEM (Depression less Digital Elevation Model),根据地形自动圈定Milli流域,划分为11个微流域MWS 1 ~ MWS 11。研究区毫米波流域的河流等级为一至二。每个参数都根据它们的值被分配了等级。然后,计算每个微流域的等级得分平均值。复合因子(Cp)最低的微流域在微流域组中优先级最高,反之亦然。形态计量分析的优先级排序结果显示,MWS 7优先级高,MWS 8优先级低。微流域MWS 9和MWS 11的优先级相同,即6,微流域MWS 2和MWS 4的优先级相同,即7。为控制土壤侵蚀,应在高优先级的微流域采用各种土地修复方案和生物工程方法,其次是中、低优先级。

E-National Agricultural Market (E-NAM) was launched on 14.04.2016 with a vision to bring transparency, uniformity, to realize optimum price of farmers’ produce and to provide a national wide electronic platform for trading of agricultural commodities. It has provided an alternate in form of a national market for marketing of agricultural commodities other than traditional way of marketing.26 wholesale markets of Himachal Pradesh are linked with E-NAM portal. Initially, two mandis namely APMC Dhalli and APMC Solan were chosen as pilot mandis as on 14th April, 2016, subsequently 5 more mandis by September 2016 ,12 mandis by March, 2017and 7 mandis by June 2022 were integrated in phased manner with e-National Agriculture Market Portal. At present, in addition to 26 existing market yards, 12 more market yards are proposed to be brought in the ambit of e-NAM. NAM must ensure farmers get paid on time and in full. e NAM should also ensure that the entire ecosystem including assaying and grading works in tandem to ensure that all-India participation works well in order to get our farmers a remunerative price for their produce.
E-National Agricultural Market (E-NAM)于2016年4月14日启动,旨在带来透明度,统一性,实现农民农产品的最佳价格,并为农产品交易提供全国范围的电子平台。它为农业商品的销售提供了一个国家市场的形式,而不是传统的销售方式。喜马偕尔邦的26个批发市场与E-NAM门户网站相连。最初,APMC达利和APMC索兰两个mandi于2016年4月14日被选为试点mandi,随后到2016年9月再增加5个mandi,到2017年3月再增加12个mandi,到2022年6月再增加7个mandi,分阶段与e-National农业市场门户网站整合。目前,除了现有的26个市场货栈外,政府建议再将12个市场货栈纳入电子nam的范围。不结盟运动必须确保农民按时足额获得报酬。不结盟运动还应该确保包括分析和分级在内的整个生态系统协同工作,确保全印度的参与运作良好,以便让我们的农民的产品获得有利可图的价格。

Recent advances in science and technology are raising ever-increasing security issues. In response, traditional authentication systems based on knowledge or possession have been developed, but these soon came up against limitations in terms of security and practicality. To overcome these limitations, other systems based on the individual's unique characteristics, known as biometric modalities, were developed. Of the various ways of improving the performance of biometric systems, feature fusion and the joint use of a pure biometric modality and a soft biometric modality (multi-origin biometrics) are highly promising. Unfortunately, however, we note a virtual absence of multi-origin systems in a feature fusion strategy. For our work, we therefore set out to design such a multi-origin system fusing facial features and skin color. Using OpenCV (Open Computer Vision) and Python, we extracted facial features and merged them with skin color to characterize each individual. The HOG (Histogram of Oriented Gradients) algorithm was used for face detection, and Google's deep neural network for encoding. For skin color, segmentation in the HSV (Hue, Saturation, Value) color space enabled us to isolate the skin in each image, and thanks to the k-means algorithm we had detected the dominant skin colors. The system designed in this way enabled us to go from 81.8% as a TR (Recognition Rate) with the face alone to 86.8% after fusion for a TFA (False Acceptance Rate) set at 0.1% and from 0.6% as a TEE (Equal Error Rate) to 0.55%.
近年来科学技术的进步引发了日益严重的安全问题。因此,基于知识或所有权的传统身份验证系统得到了发展,但这些系统很快就遇到了安全性和实用性方面的限制。为了克服这些限制,基于个人独特特征的其他系统被开发出来,称为生物识别模式。在提高生物识别系统性能的各种方法中,特征融合以及纯生物识别模式和软生物识别模式(多源生物识别)的联合使用是非常有前途的。然而,不幸的是,我们注意到在特征融合策略中几乎没有多起源系统。因此,在我们的工作中,我们开始设计这样一个融合面部特征和肤色的多原点系统。使用OpenCV(开放计算机视觉)和Python,我们提取面部特征并将其与肤色合并以表征每个个体。采用HOG (Histogram of Oriented Gradients)算法进行人脸检测,谷歌的深度神经网络进行编码。对于肤色,HSV (Hue, Saturation, Value)色彩空间的分割使我们能够在每张图像中隔离皮肤,并且由于k-means算法,我们已经检测到优势肤色。以这种方式设计的系统使我们能够将单独使用人脸的TR(识别率)从81.8%提高到融合后设置为0.1%的TFA(错误接受率)后的86.8%,并将TEE(相等错误率)从0.6%提高到0.55%。

Capital is the most important input in any sector in any country, and agriculture is no exception. The agricultural sector's performance and productivity are determined by the availability of capital for farming activities. As a result, the agriculture sector requires support or credit in order to grow and survive. Agriculture credit is desperately needed to improve the agricultural sector's performance and production. Before financial reforms, the main source of agriculture credit was non-institutional sources i.e. Sahukars, Mahajanas, Moneylenders etc. and they were providing credit facility to farmer households at very high interest rates. The study was carried out in purposively selected district of Kannauj, Uttar Pradesh. The present study has made an attempt to study as the Kisan Credit Card Scheme is being implemented in the district as well as the researcher is well acquainted with the area. 158 beneficiaries and 158 non-beneficiaries were selected randomly for the current study. The main objective of present study is to investigate the challenges and issues in the adoption of Kisan credit card scheme by farmer households and how much this scheme succeed in resolving the previous issues and challenges. Credit availability for agricultural activities is the crucial input for improving the performance and productivity of the agriculture sector. The research aims to find out the sources of finance before and after the adoption of KCC Scheme opted by farmer households for availing the credit to fulfill the capital requirement of agriculture and allied activities. The analysis demonstrates a considerable favorable change in recipients' preferred source of credit following the implementation of the KCC scheme. Following the implementation of the KCC Scheme, the beneficiaries' credit sources moved from non-institutional to institutional. The Kisan Credit Card schemes revolutionized rural financing in India. This study will be extremely useful in determining the best way to distribute the KCC plan.
资本是任何国家任何部门最重要的投入,农业也不例外。农业部门的业绩和生产力取决于农业活动资金的可得性。因此,农业部门需要支持或信贷才能发展和生存。迫切需要农业信贷来改善农业部门的业绩和生产。在金融改革之前,农业信贷的主要来源是非机构来源,即Sahukars、Mahajanas、Moneylenders等,他们以非常高的利率向农户提供信贷便利。该研究是在有目的地选择的北方邦坎瑙季地区进行的。由于Kisan信用卡计划正在该地区实施,并且研究人员对该地区非常熟悉,因此本研究试图进行研究。本研究随机选取158名受益人和158名非受益人。本研究的主要目的是调查农户采用Kisan信用卡计划所面临的挑战和问题,以及该计划在多大程度上成功解决了以前的问题和挑战。为农业活动提供信贷是改善农业部门业绩和生产力的关键投入。本研究旨在找出农户选择KCC计划前后的资金来源,以利用信贷来满足农业及相关活动的资金需求。分析表明,实施KCC计划后,受助人首选的信贷来源发生了相当有利的变化。在KCC计划实施后,受益人的信贷来源从非机构转为机构。Kisan信用卡计划彻底改变了印度农村的融资方式。这项研究对于确定分发KCC计划的最佳方式非常有用。

World Bank (1984) for instance defined the domestic labour subcontracting DLS as a union of activities that leads to the construction of buildings at relatively low-cost. This study was conducted to explore the role of labour-only subcontracting in the housing delivery in Ghana and the factors that drive this system, Tamale Metropolis was the research area. The significant of this study is to help the government, clients, contractors and other stake holders in the building industry appreciate how the use of labour-only subcontracting can improve the supply of housing in the Ghanaian building industry. Descriptive survey design with quantitative methods was utilized. The researcher used purposive sampling technique to sample 190 individual house owners whiles census technique was adopted to use the 42 estate developers in the Metropolis for the study. Two separate questionnaires were used which was a 5-point likert scale to gather data to address the research question. The instruments were pilot tested and the reliability coefficients were estimated to be .893 and .843 for the individual house owners and estate developers respectively. The statistical tools adopted for the analysis of the research question were means and standard deviations, frequencies and percentages for the demographic data. Independent sample t-test tool was used to determine whether there was any statistically significant difference between the estate developers and the individual house owners sampled in relation to the drivers of labour-only subcontracting. The data analyzed showed that there was no statically significant difference between the two groups. The findings of the study showed that an increase in productivity, quality and cooperation, highly flexibility and convenience and lack of ready funds/cash were identified as the major drivers of the labour-only subcontracting. It is recommended that the necessary policies be implemented to create training centers in the country with proper regulatory measures to ensure that the youth build much more skills to meet modern requirements.
例如,世界银行(1984)将国内劳务分包DLS定义为以相对低成本建造建筑物的活动联盟。本研究旨在探讨劳务分包在加纳住房交付中的作用以及推动这一系统的因素,研究区域为塔马利大都市。这项研究的意义在于帮助政府、客户、承包商和建筑行业的其他利益相关者认识到,仅使用劳动力分包如何改善加纳建筑行业的住房供应。采用定量方法的描述性调查设计。本研究采用目的性抽样方法对190名个体业主进行抽样,采用人口普查方法对42家大都市房地产开发商进行抽样研究。使用了两份独立的问卷,这是一个5分李克特量表来收集数据,以解决研究问题。对这些工具进行了试点测试,估计个体业主和房地产开发商的信度系数分别为0.893和0.843。分析研究问题所采用的统计工具是人口统计数据的均值和标准差、频率和百分比。使用独立样本t检验工具来确定抽样的房地产开发商和个人房主之间在劳动力分包驱动因素方面是否存在统计学上的显著差异。经数据分析,两组间无统计学差异。研究结果表明,生产力、质量和合作的提高、高度的灵活性和便利性以及缺乏现成的资金/现金被确定为只承包劳动力的主要驱动因素。建议实施必要的政策,在国内建立培训中心,采取适当的监管措施,确保年轻人掌握更多的技能,以满足现代的要求。

In Burkina Faso, vegetable production struggles to meet the needs of a rapidly growing population. This situation is largely explained by the low productivity of agricultural farms, which is due, among other things, to low rates of diffusion and adoption of innovations proposed by agricultural research. To identify the determinant factors of perceptions that influence the choice to adopt or not Good Agricultural Practices (GAP) by vegetable growers, a socio-economic and socio-demographic survey was conducted among 85 trained vegetable growers operating in the COMABO and Kotédougou sites in the municipality of Bobo Dioulasso. The study reveals that the use of GAP improves monetary income by 32.61% for cabbage and 71.17% for tomatoes. However, only 43% of vegetable growers perceive income improvement as the main result of adopting GAP. The econometric analysis of the survey data using a logistic model identified the factors that determine the probability of adopting the GAP technical package at 74.1%. Thus, in vegetable farming, gender, age group, ethnicity, and household head responsibility are determinants that have contributed to a significant increase or decrease in the probability of adopting GAP proposed by agronomic researchers. Indeed, the more a vegetable grower is male (significant at 5%) and older (young or adult) (significant at 10%), the more he tends to perceive income improvement as a favourable factor for adopting GAP. The diffusion and adoption of GAP could increase yields in vegetable production.
在布基纳法索,蔬菜生产难以满足快速增长的人口的需求。这种情况在很大程度上可以用农业农场的低生产率来解释,这除其他外,是由于农业研究提出的创新的传播和采用率低。为了查明影响蔬菜种植者选择采用或不采用良好农业规范的观念的决定因素,对Bobo Dioulasso市COMABO和kotsamadougou地点的85名受过培训的蔬菜种植者进行了社会经济和社会人口调查。研究表明,使用GAP,白菜和番茄的货币收入分别提高了32.61%和71.17%。然而,只有43%的蔬菜种植者认为收入的提高是采用GAP的主要结果。使用logistic模型对调查数据进行计量分析,确定了决定采用GAP技术包概率的因素为74.1%。因此,在蔬菜种植中,性别、年龄组、种族和户主责任是农艺学研究人员提出的采用GAP的可能性显著增加或减少的决定因素。事实上,蔬菜种植者中男性(显著为5%)和年龄越大(年轻人或成年人)(显著为10%),他越倾向于将收入提高视为采用GAP的有利因素。GAP的推广和采用可以提高蔬菜生产的产量。

Solar energy has grown exponentially around the world because it is clean and renewable, with this, photovoltaic plants are installed for its consumers as well as to relieve the electrical system of the country and guarantee the reliability. In this way, carrying out a correct dimensioning and finding a layout for the execution of a solar plant is important because it can increase or minimize the electrical losses as well as the investment. This study uses the genetic algorithm in order to find better layout to optimize the energy loss on an implanted solar power plant and resize the conductors by current capacity and voltage drop, the study shows how to program Excel to solve the multi-positioning problem through the genetic algorithm in a solar power plant. The results show that the optimization proposed by the genetic algorithm was able to reduce electrical losses by 75% and the net present value over a period of 25 years was reduced by 25%. Future research will be carried out considering 3D plans covering solar plants that are installed on the roof.
