It saved on water, labor and use of agrochemicals, reduced greenhouse gas emissions, and improved soil health and crop yield and thus benefitted both farmers and the society at large.<\/li><li><strong>Statement 2 is correct:<\/strong> Direct-seeded rice (DSR) is a viable option to reduce unproductive water flows. DSR refers to the process of establishing a rice crop from seeds sown in the field rather than by transplanting seedlings from the nursery. Conventional rice establishment system requires a substantial amount of water. However, with the increasing shortage of water, dry-DSR with minimum or zero tillage further enhances the benefits of this technology by saving labour.<\/li><li><strong>Statement 3 is correct: <\/strong>No tilled soils tend to be cooler than others, partly because a the surface layer of plant residues is present. Carbon is sequestered in the soil enhancing its quality, reducing the threat of global warming.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/edukemy.com\/free-resources-for-upsc?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Resources\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"1280\" height=\"300\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png\" alt=\"\" class=\"wp-image-42398 lazyload\" data-srcset=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18.png 1280w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-1170x274.png 1170w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/18-585x137.png 585w\" data-sizes=\"(max-width: 1280px) 100vw, 1280px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1280px; --smush-placeholder-aspect-ratio: 1280\/300;\" \/><\/a><\/figure>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel \u2013&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
