Abstract
Rice, a crucial staple crop for global food security, requires efficient production to meet the nutritional needs of an expanding population. Seed vigour is a crucial aspect of seed quality, and ANDUAT has introduced rice cultivars designed for the agricultural terrain of Acharya Narendra Deva University of Agriculture & Technology in India. This approach aims to improve seed vigour and quality in response to changing agro-climatic conditions. The study used a completely randomised design to assess seed vigour using various metrics such as electrical conductivity, field emergence, radicle emergence time, mean germination time, germination percentage, speed of emergence, shoot length, root length, days to first count, and days to final count. The study's findings revealed that rice types were categorized into three based on seed vigour. Eleven seeds showed varying levels of seed vigour potential, ranging from high to medium to low, NDR-359, IR-64, Damini, Sarjoo-52, Nagina-22, DRR-44, Barani Deep, Varalu, Lalat, NDR-2065 and NDR-2064. The study provides eleven categories for informed decision-making in seed management and cultivation, highlighting the suitability of high-vigor varieties for direct planting and improving agricultural yield.
