उत्तर और व्याख्या · explanation in English
Answer: (a) केवल 1, 2 और 3
Crop diversification, legume intensification and tensiometer use are eco-friendly practices: they cut risk and chemical inputs and save water. Vertical farming, a factory-like indoor system, is not counted among India's eco-friendly farming practices.
- ✓ 1. Diversification means changing the cropping pattern and adding other activities. The Centre's Crop Diversification Programme shifts water-guzzling paddy to pulses, oilseeds and other crops, and restores soil fertility through leguminous crops.
- ✓ 2. ICAR's review calls legumes in cropping systems a pathway to sustainable production, because they fix nitrogen and improve soil fertility while cutting water use and pest pressure.
- ✓ 3. A tensiometer measures soil matric potential, which ICAR research uses to schedule irrigation by the soil's need instead of a fixed interval, so water is not wasted.
- ✗ 4. Vertical farming is a high-technology indoor system whose benefits the IPCC calls unproven so far, so it is not treated as an established eco-friendly practice in India.
Remember · Eco-friendly farming: diversify crops, put legumes in rotation, irrigate by soil-moisture readings (tensiometer); vertical farming is not on this list.
