The study was conducted at Chandel district, Manipur state aiming to assess the impact of rice production under Frontline Demonstration (FLD) in terms of yield, yield gap/extension gap, technological gap and economic gains during kharif season from 2018 to 2022. The present Front Line Demonstration on rice var. RC-Maniphou-13 was carried out by Krishi Vigyan Kendra, Chandel, ICAR-RC for NEH Region, Manipur Centre at 40 hectares in 92 farmers’ field of different villages. The result indicated that average grain yield of rice in demonstration field ranged between 57.60 to 60.60 q/ha whereas in farmers’ practices, it was 42.50 to 47.33 q/ha during demonstrated years. The percent increase in yield with Demonstration Practices over Farmers’ Practices ranged between 28.04 to 35.53. The yield gap/technological and extension gap were from 9.40 to 12.40 and 13.27 to 15.10 q/ha respectively. Similarly, technological index was decreased from 17.71 to 13.43 per cent during the study period. The benefit cost ratio was from 1.98 to 2.65 under demonstration, while it was from 1.09 to 1.91 under farmer practices. By conducting Front Line Demonstration on improved practices with HYV of proven technologies in farmers’ field, yield potential of rice enhanced to a great extent which increased in production and productivity, also the income level of farmers has improved the livelihood of farming community in the region by reducing the technology gaps.

“…Manipur is one of the eight states in Northeast India, where rice is the most important crop occupying 82% of its total gross cropped area (Singha and Mishra, 2015). The nutrient supply potentials of rice are of paramount importance in the state due to its significant share as a staple food in rice-based diets.…”

Purpose Rice landraces are essential for supplying beneficial traits for developing improved rice varieties with better nutritional quality. Nevertheless, in a yield-driven environment, grain nutritional quality has been ignored especially that of rice landraces. Given this, the purpose of this study is to evaluate the content and nutritional variability of rice landraces from Manipur. Design/methodology/approach Thirty-three most popular rice landraces were collected as dry paddy samples from Manipur and transported to the National Institute of Nutrition, Hyderabad, by air. All the paddy samples were processed and analyzed for 35 nutrient parameters using standard methodologies. Findings The mean nutrient content of Nagaland brown rice was: protein 7.5 ± 0.8, fat 3.0 ± 0.3, TDF 5.5 ± 0.4 and ash 1.2 ± 0.2 g/100g. The range of water soluble-vitamin content in mg/100g, was 0.1–0.43 for Thiamine and for Niacin 2.1–3.5, while the content in µg/100g was 40–64 for Riboflavin, 0.5–3.9 for Pantothenic acid and 20–118 for Pyridoxine. A relatively large coefficient of variation was observed for iron (25%), manganese (28%), copper (32%), calcium (13%) and phosphorus (11%). Manipur rice landraces have significantly higher total dietary fiber and lower phytate contents than modern varieties. Milling led to steep losses of nutrients, and limiting to 5% milling substantially improves nutrient retention in milled rice. Research limitations/implications Future nutrition interventions should use rice with superior nutrient quality to improve nutrient intakes. Manipur rice landraces conserved over generations can broaden the genetic base of breeding stocks especially in the face of climate change. Originality/value The paper presents comprehensive nutritional data of 33 rice landraces from the state of Manipur, India. The results indicate large nutrient variability even within these 33 rice landraces with important traits such as high total dietary fiber and low phytate contents. The study highlights the importance of conserving the existing rich genetic material of Manipur rice landraces to develop varieties that combine higher yields with stress tolerance and superior grain nutritional value to improve the food and nutrient security.

“…On an average, the discovery of a new drug from initial findings to its marketing stage, takes months to years. For this reason, several research groups have paid their attention to drug repurposing strategies to find out the potential inhibitors for SARS‐CoV‐2 virus replication [10–18,35–40] . In this study, we aim to screen the DrugBank database (http://www.drugbank.ca/, release version 5.1.8) using the computational approach with an intention to identify small molecules that exhibit inhibitory properties against the SARS‐CoV‐2 main protease enzyme to fasten the drug discovery process.…”

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS‐CoV‐2) is highly pathogenic to humans and has created an unprecedented global health care threat. Globally, intense efforts are going on to discover a vaccine or new drug molecules to control the COVID‐19. However, till today, there is no effective therapeutics or treatment available for COVID‐19. In this study, we aim to find out potential small molecule inhibitors for SARS‐CoV‐2 main protease (M pro ) from the known DrugBank database version 5.1.8. We applied structure‐based virtual screening of the database containing 11875 numbers of drug candidates to identify potential hits for SARS‐CoV‐2 M pro inhibitors. Seven potential inhibitors having admirable XP glide score ranging from −15.071 to −8.704 kcal/mol and good binding affinity with the active sites amino acids of M pro were identified. The selected hits were further analyzed with 50 ns molecular dynamics (MD) simulation to examine the stability of protein‐ligand complexes. The root mean square deviation and potential energy plot indicates the stability of the complexes during the 50 ns MD simulation. The MM‐GBSA analysis also showed good binding energy of the selected hits (−83.2718 to −58.6618 kcal/mol). Further analysis revealed critical hydrogen bonds and hydrophobic interactions between compounds and the target protein. The compounds bind to biologically important regions of M pro , indicating their potential to inhibit the functionality of this component.
