What is/are the advantage/advantages of zero tillage in agriculture ? 1. Sowing of wheat is possible without burning the residue of previous crop. 2. Without the need for nursery of rice saplings, direct planting of paddy seeds in the wet soil is possible. 3. Carbon sequestration in the soil is possible. Select the correct answer using the code given below:

1. Zero tillage (No-till farming) is an agricultural practice where crops are sown directly into the soil without prior plowing or tilling, often leaving the residue of the previous crop on the surface. 2. Statement 1 is correct. Specialized seed drills used in zero tillage can sow wheat seeds directly into the fields even with the presence of residue from the previous crop (like rice stubble), thus making sowing possible without burning the residue. 3. Statement 2 is correct. Zero tillage facilitates Direct Seeded Rice (DSR) techniques, where paddy seeds can be directly planted into the wet soil, eliminating the need for raising saplings in a nursery and transplanting them. 4. Statement 3 is correct. By leaving crop residue on the surface and minimizing soil disturbance, zero tillage helps increase the organic matter content in the soil over time. This process enhances carbon sequestration in the soil, contributing to climate change mitigation. 5. Therefore, all three statements represent advantages of zero tillage in agriculture.
