This study was performed to further understanding of the variations in hydrology and rice crop productivity during different El Niño/Southern Oscillation (ENSO) events Cauvery River Basin Tamil Nadu, India using Soil Water Assessment Tool (SWAT). The entire divided into 301 sub-basins subdivided 3,601 Hydrological Response Units (HRU). Based on National Oceanic Atmospheric Administration (NOAA) official website, information Niño (1972, 1982, 1987, 1991, 1997, 2002 2004) La Niña (1970, 1971,...
Accurate and consistent information on the area production of field crops is vital for national state planning ensuring food security in India. Satellite-based remote sensing offers a suitable cost-effective technique regional- national-scale crop monitoring. The use data yield estimation has been demonstrated using semi-physical approach with reasonable success. Assimilating DSSAT model spectral indices-based regression analysis are promising methods spatially estimating rice yields. Rice...
Agroforestry is a management strategy for mitigating the negative impacts of climate and adapting to sustainable farming systems. The successful implementation agroforestry strategies requires that risks are appropriately assessed. spatial scale, critical determinant influencing impact assessments and, subsequently, strategies, has been an overlooked dimension in literature. In this study, risk on robusta coffee production were investigated at different scales coffee-based systems across...
Coastal zone is exposed to various natural forces including cyclones and tsunamis, which are constantly affecting the shorelines, beaches headlands, causing storm surges, erosion/accretion, landslides, coastal flooding. Magnitude risk of disasters directly proportional sensitivity inversely degree resilience community. To mitigate ill effects hazards, a thorough understanding vulnerability factors coping capabilities required for analysis essential. A study was undertaken in most vulnerable...
Field experiments were conducted during summer (March–July) and kharif (June–September), 2008 at the wetland farm, Tamil Nadu Agricultural University, Coimbatore, India, to study performance of different rice cultivation methods on productivity water usage using hybrid CORH-3 as a test crop. Treatments consisted methods, namely, transplanted (conventional), direct sown (wet seeded), alternate wetting drying method (AWD), system intensification (SRI) aerobic cultivation. Results revealed that...
The prevalence of the frequent water stress conditions at present was found to be more due increased weather anomalies and climate change scenarios, among other reasons. Periodic drought assessment subsequent management are essential in effectively utilizing managing resources. For effective monitoring/assessment, satellite-based precipitation products offer reliable rainfall estimates with higher accuracy spatial coverage than conventional rain gauge data. study on monitoring reliability...
Introduction Rice, one of the major staple food crops is frequently affected by various biotic/abiotic stresses including drought, salinity, submergence, heat, Bacterial leaf blight, Brown plant hopper, Gall midge, Stem borer, Leaf folder etc. Sustained increase yield growth highly necessary to meet projected demand in rice production during year 2050. Hence, development high yielding and multiple stress tolerant varieties adapted wider environments will serve need. Methods A systematic MAB...
The soil–environmental relationship identified and standardised over the years has expedited growth of digital soil-mapping techniques; hence, various machine learning algorithms are involved in predicting soil attributes. Therefore, comparing different is essential to provide insights into performance information for Indian landscapes. In this study, we compared a suite six predict quantitative (Cubist, decision tree, k-NN, multiple linear regression, random forest, support vector...
In tomato (Lycopersicon esculentum L.), the effects of combined drought (D) and high temperature (HT) stress during flowering stage had not been studied in detail. Therefore, this study was conducted with an objective quantifying foliar spray melatonin under individual HT stress. At stage, D imposed through withholding irrigation, while exposing plants to ambient (AT) along increase +5 °C. Under + HT, were first subjected followed by a 5 °C AT. The duration or ten days. 80% available soil...
Melatonin (MT), a naturally occurring compound, is found in various species worldwide. In 1958, it was first identified the pineal gland of dairy cows. MT an “old friend” but “new compound” for plant biology. It brings experts and research minds from broad field sciences due to its considerable influence on systems. The production process plants animals distinct, where has been expressed explicitly chloroplasts mitochondria plants. Tryptophan acts as precursor formation phyto-melatonin,...
Trend analysis of annual rainfall over the coastal districts Odisha, India showed statistically nonsignificant increasing trend in all districts, except Ganjam.Whereas maximum and minimum temperature significant trend.Warming these is mainly due to during summer rainy season, winter.Future climate projection results revealed, mean expected change by 0.1-2.2%,-0.3-0.7% 1.5-3.2%(RCP 4.5), 3.6-7.9%,3.7-6.6%and 8.5-14% (RCP 8.5) near (2011-39), mid (2040-69) late (2070-99) centuries...
Drought is one of the most challenging disasters that impact natural and cultural ecosystems across world, especially in climate dependent sectors arid semi-arid areas. The aim this article to share experiences gained enhance readers’ awareness on status drought process early warning systems (EWS) south India. three agroecologically different states included article, such as Kerala, Tamil Nadu Telangana. As far concerned, Karur, Thuthukudi, Krishnagiri, Namakkal, Trichy Thirunelveli...
In this study, an extensive exploration survey of wild progeny was conducted which yielded 18 candidate plus trees (CPTs) Terminalia bellerica. Seeds these CPTs were collected from diverse locations between 10°54′ and 28°07′ E longitude, 76°27′ 95°32′ N latitude, covering different across 5 states the Indian subcontinent. The objective trial to assess genetic associations variability in growth physio-chemical characteristics. Significant variations (p < 0.05) observed among traits,...
Blackgram, a protein-rich pulse crop (24%), is crucial for combating food insecurity, particularly in malnourished and economically weak countries. Enhancing blackgram production requires improved, input-saving management practices. Given the challenges of climate change population growth, efficient water vital increasing productivity use efficiency with minimal investment. This study aimed to identify cost-effective irrigation methods optimise yields. Experiments were conducted at National...
Abstract Background Multi drug resistant Healthcare Associated Infections (MDR HAI) pose significant challenges for both patients and healthcare facilities, often stemming from inappropriate antibiotic usage. 'Handshake Stewardship' involves a proactive approach of auditing providing feedback on prescriptions to ensure their rationality, with discussions held confidentially treating physicians. Endorsed by the Centers Disease Control Prevention The Joint Commission, this method aims engage...
Abstract Background Limited research has explored the efficacy of Antimicrobial Stewardship (AMS) interventions in reducing Infection-Related Mortality (IRM).
