Fusarium wilt incited by Fusarium oxysporum f. sp. ciceris is one of the important fungal diseases of chickpea responsible for causing substantial yield losses. This paper summarizes the plethora information available on Fusarium wilt of chickpea in regard to history, geographical distribution, symptomatology, disease epidemiology and various management tactics viz., chemical, plant extracts, biological along with future prospects.
A two year field experiment was conducted to investigate the effect of seed priming and plant geometry on growth and yield of wheat crop in modified system of wheat intensification under irrigated sub tropics of Jammu. Experiment was laid out in randomized block design with three replications and ten treatments viz.conventional sowing (Check), un-primed seed sown at plant geometry of 20 cm × 5 cm, un-primed seed sown at plant geometry of 20 cm × 10 cm, un-primed seed sown at plant geometry of 20 cm ×15 cm, un-primed seed sown at plant geometry of 20 cm × 20 cm, conventional sowing of primed seed, primed seed sown at plant geometry of 20 cm × 5 cm, primed seed sown at plant geometry of 20 cm × 10 cm, primed seed sown at plant geometry of 20 cm × 15 cm and primed seed sown at plant geometry of 20 cm × 20 cm to assess the effect of seed priming at different geometry on growth and yield of wheat under MSWI. The results indicated that highest growth attributes and grain yield of wheat i.e.5244.7 kgha-1 was recorded in primed seed sown at plant geometry of 20 cm × 5 cm which was statistically at par with primed seed sown at plant geometry of 20 cm × 10 cm and conventional sowing of primed seed. Further, primed seed at different plant geometry also significantly improve growth attributes of wheat as compared to un-primed seed.
The objective of this study is thus to find suitable time series machine learning models of forecasting for cereals, vegetables, fruits, and wheat production in Turkey. Turkey, situated at the crossroads of Asia and Europe, is among the larger countries of the region with a population of over 85 million in terms of territory. Agriculture employs about a quarter of the workforce and generates most of the income and employment in rural areas. We examined five machine learning algorithms, including autoregressive integrated moving average (ARIMA), Prophet, elastic-net regularized generalized linear (GLMNet), random forest, and eXtreme Gradient Boost (XGBoost) using R programming. The performance of the algorithms was evaluated using the mean absolute percent error (MAPE). As a result, the algorithms that give the best estimates based on the MAPE error metrics were found as ARIMA and GLMNet.
Underwater Wireless Sensor Networks (UWSNs) consists of various components like vehicles (both underwater and surface), acoustic sensors etc., which can be classified as static, semi-static and dynamic nodes. These are spread across the water bodies to collect the data and to monitor the movement of vehicles, torpedoes etc. All these nodes form as networks and establishes communication with ground stations. Currently, UWSNs face problems and challenges pertain to limited bandwidth, media access control, high propagation delay, 3D topology, spectrum sensing, resource utilization, routing, and power constraints. This proposal deals with the intelligent spectrum sensing in Underwater Cognitive Sonar Communication Networks (CSCN). Here, the improved performance of spectrum sensing in underwater communication is attained by optimizing the cooperative spectrum sensing and data transmission. The parameters of system like sub-channel allocation, and transmission power are optimized by a new hybrid meta-heuristic algorithm by integrating the concepts of Whale Optimization Algorithm (WOA), and Grey Wolf Optimization (GWO) termed as WGWOA. The main intention of optimizing these parameters is to maximize the Spectrum Efficiency (SE) and Energy Efficiency (EE) of the underwater channel communication system. The analysis is done with respect to convergence rate, minimum detection probability, and local sensing time.
Robust watermarking proposals supported on human visual characteristics with a series of hybrid transform of type discrete wavelet transform (DWT) followed by singular value decomposition (SVD) is wished-for. By analyzing the matrices U or V through SVD, it is bringing into being that there stay alive a well-built relationship amid the internal column elements of U or internal row elements of V. Hence, this work will make the most of these chattels for image watermarking. At the outset, visual digital data is segregated into 8 × 8 non-overlapping pixel blocks and each block is processed for brinks by using the algorithm of detection for a canny brink. An appropriate block is decided to pick in such a way that the number of brinks in each block is only about or equal to a threshold. A threshold is defined by finding the mean of the brinks in each block of the host visual digital data. Using these appropriate blocks, we will form an image of reference. This reference image is processed by a series of operations DWT-SVD. Then, the watermark is implanted by adapting the nth column of the U matrix of the host image with the nth column of the U matrix of the watermark image. The same operation is applied on the V matrix instead of a column vector, use a row vector. The adapted relation is wont to retrieve a watermark. The experimental findings demonstrate that the ideal watermarking algorithm will guarantee that the typical image processing operations and geometric attacks are invisible and more stable. The efficiency of this proposed method is out of shape than other proposed methods examined in this research.
