Maharashtra, known for its agriculture-based economy, faces the challenge of 24% of its land being prone to drought. Despite this, the state has enormous agricultural growth potential and is a major millet producer in India. Being a climate-resilient crop, there is a huge scope for area expansion under millet cultivation in the state. The present article investigates the current trend in area, production and productivity of pearl millet (Pennisetum glaucum L.) and sorghum (Sorghum bicolor) in Maharashtra by using the Exponential Compound Annual Growth Rate (Exponential CAGR) approach. The present study reveals that the area and production of both millets in Maharashtra state are on a decreasing trend. Both millets production experienced negative growth rates, with a CAGR of −3.89% for sorghum and −2.56% for pearl millet. The present study has the potential to determine the current state of production and productivity of both millets in the state, which will help policymakers and researchers develop strategies to boost millet production in Maharashtra in the coming years.","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"125 1","pages":""},"PeriodicalIF":0.788,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This wild crucifer draws an attention for molecular plant-aphid interaction biology to address the resistance mechanism as there is no resistant source in the Brassicaceae family to aphid proliferation.

In the present study, identification of the highest resistant reaction to the aphid proliferation is focused from Rorippa indica -Myzus persicae interaction. Moreover, another objective is to identify the parameter for better visualization of the highest resistant reaction to Myzus persicae. Thus, three different aphids’ release like 5, 10 and 20 Myzus persicae were released in each foliage and monitoring the total aphid proliferation, total progeny proliferation, marginal progeny proliferation in 24, 48 and 72 h time point. Three elevated doses of aphid inoculums were explored to test the first hypothesis on whether the progeny production was dependent on an initial aphid density or not. The second hypothesis was on whether the host resistance induction was dependent on an initial aphid density or not.

However, CGI improvements make it difficult to discern synthetic photos from genuine ones. Researchers suggest multiple deep learning strategies to differentiate these photo sets utilizing thorough feature analysis. These models are either complex or do not handle image sub-components, decreasing efficiency in large-scale applications. These models fail categorically. To address these issues, this work proposes a novel high-density bio-inspired feature analysis deep learning model for natural and synthetic image sub-classification. A YoLo model initially recognizes objects in input image sets. Processed separately, a hybrid LSTM/GRU model predicts high-density feature sets, which are processed by Elephant Herding Optimization (EHO) Models to identify high inter-class variance feature sets. A customized 1D CNN model is used to categorize the desired features into natural and synthetic components. These classification results establish whether the input image is natural, synthetic, or both. In real-time scenarios, the proposed model is able to improve standard classification models with 8.7% greater accuracy, 10.9% higher precision, 3.2% higher recall, and 8.4% higher AUC.","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"73 1","pages":""},"PeriodicalIF":0.788,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140325109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Estimation of evapotranspiration and surface runoff is a challenging task for water managers and researchers. Spatial and temporal changes occur in basin due to changes in physical topography and climatic conditions. It is very much required to model the basin to understand the behaviour and amount of water available in that basin at watershed and sub-watershed scales. The information at sub-watershed scale is vital for microlevel water-related planning in the basin for different water uses. In this work, ArcSWAT model is used to estimate evapotranspiration and surface runoff at sub-watershed scales. The study area in Indravati river basin comprises of 15 sub-watershed (WS1, WS2, WS3…WS15) which were divided into 199 hydrological response units (HRUs) that satisfactorily represent basin heterogeneity. Calibration and validation of SWAT model are done using Soil water assessment tool-Calibration and uncertainty program (SWAT-CUP) software with sequential uncertainty fitting-II (SUFI-II) algorithm. Results of this study show that the total average annual runoff and evapotranspiration (ET) are 94.85% and 4.56% of average annual precipitation (PPT), respectively. The sub-watershed WS8 receives maximum annual runoff and minimum annual ET as 98.43% and 4.43% of average annual PPT, respectively. Monthly variation of runoff and ET is also presented.","PeriodicalId":717,"journal":{"name":"National Academy Science Letters","volume":"42 1","pages":""},"PeriodicalIF":0.788,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140166202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
