PYQ TREND ANALYSIS — LAST 15 YEARS

Pattern of questions

• Mix of 10 marks (short, definition + 2 - 3 points) & 15 - 20 marks (detailed package of practices, schemes, hi -tech).
• Direct questions on a single fruit/veg/spice — most common type.
• 'Compare' / 'contrast' questions — climacteric vs non - climacteric, MA vs CA storage, etc.
• Conceptual + applied — eg. fruit drop in mango → causes + remedies; alternate bearing → mechanism + management.
• Recently — emphasis on protected cultivation, hydroponics, value addition, MIDH, Operation Greens.
