Kidney beans (Phaseolus vulgaris), also known as Rajma, are a protein-rich, high-value legume crop, widely grown for their nutritional and commercial importance. With scientific cultivation practices, farmers can achieve higher yields, better quality, and increased profitability.
Key Steps for Profitable Kidney Bean Cultivation
Ideal Climate & Soil Conditions
Temperature: 15-25°C – Prefers moderate temperatures for healthy growth
Soil Type: Well-drained loamy soil with high organic content (pH 6.0-7.5)
Water Requirement: Requires moderate irrigation at key growth stages
High-Yielding Kidney Bean Varieties
Popular varieties: PDR 14, HUR 15, VL Rajma 63, Arka Komal
Disease-resistant types: Pant Rajma 5, Uttara – Best for disease-prone areas
Market preference: Choose between red, white, or speckled kidney beans based on demand
Smart Sowing & Seed Treatment
Seed rate: 50-75 kg/ha depending on variety
Best sowing time: Mid-June to early July (Kharif season) & October-November (Rabi season)
Seed treatment: Treat with Rhizobium & PSB (Phosphate Solubilizing Bacteria) to enhance nitrogen fixation
Nutrient & Water Management
Balanced fertilization:
- Nitrogen (N): 20-30 kg/ha
- Phosphorus (P): 40-60 kg/ha
- Potassium (K): 25-30 kg/ha
Irrigation schedule: Essential at flowering, pod formation & grain filling stages
Weed, Pest & Disease Control
Weed management: Use Pendimethalin (pre-emergence herbicide) for weed control
Common pests: Bean aphids, whiteflies – Managed with Neem-based biopesticides
Disease control: Rust, bacterial blight – Prevent with proper crop rotation & fungicides
Harvesting & Post-Harvest Management
Harvest when pods turn yellow-brown & beans harden
Proper drying ensures longer shelf life & better market price
Average yield: 2.0-3.5 tons per hectare
