RÉSUMÉ
Tillage is the physical manipulation of soil into optimum conditions, which enhance the soil health for better crop productivity. A field investigation was carried out to evaluate conservation agriculture effect on soil nutrient conservation and set up in spilt plot design. Zero tillage (M3) witnessed significantly (P<0.05) greater nitrogen availability (288.17, 251.39 and 239.70 kg ha-1), K2O (229.04, 209.80 and 193.73 kg ha-1) than conventional tillage (M1) at soil depths 0-7.5, 7.5-15 and 15-30 cm, respectively. In green manuring practices, horse gram (C3) recorded OC (0.53, 0.51 and 0.47 %), available sulphur (23.38, 20.61 and 18.10 mg kg-1) followed by sun hemp. The interaction combination of M3C3 recorded highest soil nutrient status. Significantly lowest microbial population were found in M1, was due to faster decomposition organic matter resulted in unfavourable condition for survival. Overall adopting M1 alone (1 Ploughing + 2 harrowing + 1 intercultural operation) adversely affect soil health.
RÉSUMÉ
As the world grapples with the problem of the coronavirus disease 2019 (COVID-19) pandemic and its devastating effects, scientific groups are working towards solutions to mitigate the effects of the virus. This paper aimed to collate information on COVID-19 prediction models. A systematic literature review is reported, based on a manual search of 1,196 papers published from January to December 2020. Various databases such as Google Scholar, Web of Science, and Scopus were searched. The search strategy was formulated and refined in terms of subject keywords, geographical purview, and time period according to a predefined protocol. Visualizations were created to present the data trends according to different parameters. The results of this systematic literature review show that the study findings are critically relevant for both healthcare managers and prediction model developers. Healthcare managers can choose the best prediction model output for their organization or process management. Meanwhile, prediction model developers and managers can identify the lacunae in their models and improve their data-driven approaches.
