Correct answer: 1, 2 and 3. The practice of sowing seed without tillage or prepara- tion of soil is called Zero-tillage or No-till farming. In some cases it may reduce labour, fuel, irrigation and machinery costs. Anoth- er possible benefit is that because of the higher water content, instead of leaving a field fallow it can make economic sense to plant another crop instead. No-till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain. Statement 1 is correct: Zero tillage is the process where the crop seed will be sown through drillers without prior land prepa- ration and disturbing the soil where previous crop stubbles are present. Statement 2 is correct: Direct Seeded Rice (DSR) is a viable option to reduce the unproductive water flows, with increasing shortage of water, dry-DSR with minimum or zero tillage further enhances the benefits of this technology by saving labour. Statement 3 is correct: Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate cli- mate
