- 1Agricultural practices in sequential order: Soil preparation → Sowing → Manure/Fertiliser → Irrigation → Weeding → Harvesting → Storage.
- 2Modern water-saving irrigation techniques: Drip irrigation (drops at root zone) and Sprinkler systems.
- 3Biological nitrogen fixation through Rhizobium bacteria in leguminous root nodules.
🚨 Examiner Traps & Common Mistakes
⚠️ Common Student Pitfall
Mixing up Kharif (monsoon) and Rabi (winter) crop examples in exam matching questions.
⚠️ Common Student Pitfall
Confusing manures (organic, improves soil humus) with chemical fertilisers (inorganic salts, specific NPK nutrients).
