Cultivation of Gram (Chickpea/Bengal Gram)
- Botanical Name: Cicer arietinum
- Family: Fabaceae (Leguminaceae)
- Sub-Family: Papilionaceae
- Chromosome Number: 2n = 14 or 16
- Origin: Afghanistan (South-West Asia)
- Edible Part: Seeds
- Test Weight: 140-200 g (Desi), 340-375 g (Kabuli)
- Protein Content: 21%
Importance and Distribution
- India is the largest producer of gram, contributing 65% of the global area and 70% of total global production.
- Gram is rich in calcium, iron, and niacin.
- It is used as a blood purifier, and germinated seeds are recommended for treating scurvy disease.
- Most legumes fulfill 75% of their nitrogen requirement through root nodules (symbiotic nitrogen fixation).

Classification of Gram
- Desi or Brown Gram (Cicer arietinum)
- Most widely cultivated in India.
- Good branching habit.
- Small, yellow to dark brown seeds.
- Test weight: 140-200 g.
- Kabuli or White Gram (Cicer kabulium)
- Larger, attractive white seeds.
- Plants are taller.
- Lower yielding compared to Desi gram.
- Test weight: 340-375 g.
The sour taste of leaves and pods is due to Malic Acid (90-96%) and Oxalic Acid (4-10%). About 4-10 kg of these acids can be obtained from one hectare crop.
Botany
- C3, long-day plant.
- Tap root system.
- Cloddy and rough seed bed is required to provide adequate aeration for proper germination, as gram is highly sensitive to soil aeration.
- Highly susceptible to frost at the flowering stage.
Varieties of Gram
Desi Gram Varieties
- Avrodhi – Wilt resistant.
- Pusa 256/BG 256 – Most common, best for rainfed conditions.
- Gaurav – Resistant to Ascochyta blight.
- RS-10, RS-11 – Good yielding.
- ICCC-2 – Short-duration variety.
- Aparna – Grains remain green.
- Type-2, Radhey, Chaffa, Pusa-209, Uday – Suitable for various conditions.
Kabuli Gram Varieties
- C-104, K-4, L-144 – Large seeds, high market demand.
Cultivation Practices
Seedbed Preparation; A rough seedbed is required to ensure proper aeration. Proper soil preparation helps prevent diseases and improves root penetration.
Sowing Time; Recommended: 15-20 October (2nd fortnight of October).
Seed Rate & Spacing
- Seed Rate: 80-100 kg/ha.
- Row Spacing: 30 cm row-to-row and 10 cm plant-to-plant.
- Sowing Depth: 8 cm to prevent wilt disease.
Delayed planting increases the incidence of pod borer (Helicoverpa armigera). 👉 Early and shallow sown crops are more susceptible to wilt.
Nutrient Management
- Farmyard Manure (FYM): 5-10 tons/ha.
- Recommended NPK Dose: 20:50:20 (N:P:K kg/ha).
- Micronutrients: Apply ZnSO₄ @ 20-25 kg/ha if deficiency is observed.
- Rhizobium and PSB treatment (@ 5 g/kg seed) enhances nitrogen fixation and phosphorus uptake.
Irrigation Management
- Pre-flowering and pod development are the most critical stages for irrigation.
- No irrigation should be provided at the flowering stage to avoid flower drop.
Weed Management
- Herbicide Application: Apply Pendimethalin (Basalin) @ 1 kg a.i./ha before sowing.
- Hand Weeding: 25-30 DAS (Days After Sowing) to ensure good growth.
Pest and Disease Management
Major Insect-Pests & Management
- Pod Borer (Helicoverpa armigera) Spray Neem oil @ 5 ml/L or Spinosad @ 0.2 ml/L. Install pheromone traps (5/ha).
- Aphids & Thrips Spray Imidacloprid @ 0.3 ml/L.
Major Diseases & Management
- Wilt (Fusarium oxysporum) Use wilt-resistant varieties (JG 11, Pusa 362). Soil drenching with Carbendazim @ 1 g/L.
- Ascochyta Blight; Spray Mancozeb @ 2 g/L.
Special Practices in Gram Cultivation
Nipping and Topping
- Definition: Removal of the tips of young branches (50-60 DAS).
- Purpose: Encourages lateral branching, increases yield.
- Method: Rapidly passing a flock of sheep in the field.
- Chemical for Nipping: TIBA (Tri-iodo-benzoic Acid) @ 75 PPM.
Yield & Harvesting
- Maturity Duration: 100-120 days.
- Yield: 20-25 q/ha (Irrigated), 12-18 q/ha (Rainfed).
- Harvesting Time: February-March.
Storage and Post-Harvest Management
- Moisture Content: 10-12% for safe storage.
- Storage Temperature: 5-10°C.
- Storage Pest Management: Use neem leaves or aluminum phosphide tablets.
