Kharif vs Rabi vs Zaid Crops
| Feature | Kharif | Rabi | Zaid |
|---|---|---|---|
| Season | June–October (monsoon) | October–March (winter) | March–June (summer) |
| Sowing | June–July | October–November | March |
| Harvesting | September–October | March–April | June |
| Examples | Rice, maize, cotton, jowar, bajra, soybean | Wheat, barley, mustard, chickpea, peas | Watermelon, muskmelon, cucumber, vegetables |
| Water requirement | High (monsoon-dependent) | Low (irrigation often sufficient) | Medium (short-season) |
Essential Plant Nutrients — Deficiency Symptoms
| Nutrient | Deficiency Symptom | Mobile/Immobile |
|---|---|---|
| Nitrogen (N) | Chlorosis (yellowing) of older leaves first; stunted growth | Mobile |
| Phosphorus (P) | Purple/red coloration of leaves (anthocyanin accumulation) | Mobile |
| Potassium (K) | Tip and marginal scorch (necrosis) of older leaves | Mobile |
| Calcium (Ca) | Death of growing tips; blossom-end rot in tomato | Immobile |
| Magnesium (Mg) | Interveinal chlorosis of older leaves (Mg is part of chlorophyll) | Mobile |
| Iron (Fe) | Interveinal chlorosis of young leaves | Immobile |
| Zinc (Zn) | Khaira disease in rice; small leaves | Immobile |
| Boron (B) | Death of terminal buds; hollow heart in beet | Immobile |
Green Revolution — Key Facts
- Period: 1960s–1970s in India
- Key scientist: Dr. M.S. Swaminathan (Father of Green Revolution in India); Norman Borlaug (international)
- Crops: HYV (High Yielding Varieties) of wheat (Sonalika, Kalyan Sona) and rice (IR-8, Jaya)
- States first benefited: Punjab, Haryana, western Uttar Pradesh
- Impact: India’s food grain production went from 72 million tonnes (1964) to 176 million tonnes (1990)
- Limitations: Regional disparity, ecological damage (soil salinization, groundwater depletion), ignored pulses/millets

Frequently Asked Questions (FAQ)
Which universities offer B.Sc. Agriculture through CUET?
Major central universities offering B.Sc. Agriculture through CUET include Banaras Hindu University (BHU), Allahabad University, Central Agricultural University Imphal, Nagaland University, and several others. State universities may also accept CUET scores. The programmes include B.Sc. Agriculture, B.Sc. Horticulture, B.Sc. Forestry, and B.V.Sc. (veterinary).
What is the difference between biofertilizer and organic fertilizer?
Biofertilizers are living microorganisms (Rhizobium, Azotobacter, mycorrhiza, blue-green algae) that enhance plant nutrient availability through biological processes like nitrogen fixation and phosphorus solubilization. Organic fertilizers (compost, vermicompost, FYM — farmyard manure) are decomposed organic matter that enriches soil with nutrients and improves soil structure. Both are alternatives to chemical fertilizers but work through different mechanisms.
What is Bt cotton and why is it controversial?
Bt cotton is a transgenic variety that contains genes from Bacillus thuringiensis (a soil bacterium) that produce proteins toxic to certain insects (bollworm). It was the first and so far only approved GM crop in India (2002). It is controversial because: (1) monopoly of seed companies, (2) development of secondary pests, (3) failed crop reports from some regions, (4) ethical concerns about GM food, and (5) farmers’ dependency on purchased seeds. However, it significantly reduced pesticide use in cotton farming.
