Astha (Hybrid Castor)
Hybrid castor for oilseed production with good adaptation to semi-arid regions. Suitable for well-drained soils and responsive to balanced nutrient and moisture management.
Key Features
- Recommended spacing often ranges from 90 x 60 cm to 90 x 90 cm
- FYM application improves early vigor and moisture retention
- Balanced NPK with sulfur improves capsule and oil yield
- Critical crop care at flowering and capsule development stages
Growing Information
Growing Conditions
Performs best in warm conditions (20-30 C) on well-drained loam to clay loam soils, pH around 6.0-7.5. Avoid prolonged waterlogging.
Yield Estimates
With proper management, productivity generally ranges around 15-25 q/ha depending on rainfall, soil fertility and variety duration.
Packaging & Usage
Typical seed rate: 5-10 kg/ha depending on hybrid/variety and spacing.

Agronomy & Management
Soil
Well-drained medium to deep soils are preferred. Crop tolerates moderate soil stress but not standing water.
Water & Irrigation
Give life irrigation at establishment if needed, then irrigate at key stages in dry spells.
Sowing
Preparation
Prepare fine tilth with 2-3 ploughings and basal organic manure.
Sowing Depth
Sow at 3-5 cm depth.
Spacing
90 x 60 cm to 90 x 90 cm depending on duration and rainfall zone.
Sowing Methods
- •Line sowing
- •Ridge-furrow sowing in heavy rainfall areas
Sowing Time
Seed Rate
5-10 kg/ha
Harvesting
Harvest in stages as spikes mature; avoid delayed harvest to reduce shattering losses.
Post-Cutting Activities
Dry harvested spikes properly before threshing and storage.
Fertilizer
Apply balanced NPK based on soil test; sulfur application is beneficial in low-S soils.
Weed Control
Keep field weed-free during first 35-45 days through interculture and hand weeding.
Pest & Disease Management
Scout for capsule borer and leaf feeders; use integrated pest management and need-based sprays.
