In the context of India, which of the following is/are considered to be practice(s) of ecofriendly agriculture? Select the correct answer using the code given below:
- Crop diversification
- Legume intensification
- Tensiometer use
- Vertical farming
- (a) 1, 2 and 3 only
- (b) 3 only
- (c) 4 only
- (d) 1, 2, 3 and 4
Show the answer and explanation
Answer: (d) 1, 2, 3 and 4
All four are eco-friendly practices.
Statement by statement
1. ✓ YES Crop diversification reduces pests and risk.
2. ✓ YES More legumes fix nitrogen and cut fertiliser use.
3. ✓ YES A tensiometer measures soil moisture so farmers irrigate only when needed.
4. ✓ YES Vertical farming uses little land and water.
Why the others are wrong
(a) Drops vertical farming.
(b) Keeps only tensiometers.
(c) Keeps only vertical farming.
The trap
A tensiometer is a gadget, not a “practice”, so it gets dropped — but its use saves water.
🔒 Tensiometer = soil moisture meter → precision irrigation.
