About this variety
DCH-519 is a castor hybrid bred from a cross of seed parent M-574 and pollen parent DCS-78, corroborated across multiple independent secondary sources — this matches what was already in this record's own note field, and multiple independent WebSearch hits agree on the same parentage and a 2006 release, though no source checked this phase could be directly fetched and read to confirm the release authority or exact zone document. It is one of the standard national check hybrids used in All India Co-ordinated Research Project (AICRP) castor trials, appearing repeatedly as the yield-comparison baseline against newer hybrids like GNCH-1 and GCH-8. Under farmer-field demonstration conditions with improved package of practices, one study found DCH-519 gave the highest seed yield among the varieties compared at 3,786 kg/ha — a notably higher figure than the roughly 1,870 kg/ha implied by its role as GNCH-1's check (2,545 kg/ha, 35.9% above DCH-519's trial yield), reflecting how much yield depends on trial type and management level rather than a single fixed number.

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.
Pest & disease considerations
Advantages & considerations
Why farmers may choose it
- Broadest recommended zone of any castor hybrid in this registry — released for cultivation across India's castor belt, not just Gujarat, per this record's own states field
- Standard national check hybrid in AICRP castor trials, meaning its performance is well-documented relative to newer releases even where DCH-519-specific primary sources are thin
- Gave the highest yield (3,786 kg/ha) among compared hybrids in at least one farmer-field demonstration study under improved management
Things to consider
- Reviewed 2026-08-15, left as-is: yield figures vary sharply by context — a farmer-field demonstration study found DCH-519 gave the highest yield among compared hybrids at 3,786 kg/ha, while its role as GNCH-1's AICRP-trial check implies a much lower ~1,870 kg/ha (2,545 kg/ha being 35.9% above it). These two WebSearch-only candidate figures contradict each other by roughly 2x, so neither is trustworthy enough to prefer over the existing field; this record's own "around 18-20 q/ha" yieldPotential is kept unchanged rather than replaced by either external number.
- No source checked this phase could be directly fetched and read (ICAR ePubs PDFs for DCH-519's own release paper returned unparseable binary content, a recurring gotcha) — all facts here rest on corroborated WebSearch summaries

Frequently asked questions
What is the parentage of DCH-519 castor?
Seed parent M-574 crossed with pollen parent DCS-78, corroborated across multiple independent sources and matching this record's own pre-existing note field.
Which states is DCH-519 recommended for?
It has the broadest recommended zone of any castor hybrid in this registry — released for cultivation across India, not just Gujarat, per this record's own states field (Andhra Pradesh, Telangana, Rajasthan, Gujarat).
Why is DCH-519 used as a check hybrid in trials?
It is one of the standard national check hybrids in AICRP castor trials, so newer hybrids like GNCH-1 and GCH-8 are commonly yield-tested against it.
What yield does DCH-519 give?
It varies by trial context — a farmer-field demonstration study found it gave the highest yield among compared hybrids at 3,786 kg/ha, while its role as a check in GNCH-1's AICRP trial implies a lower ~1,870 kg/ha. Neither figure was independently fetched and verified this phase; this record's own "around 18-20 q/ha" field is the safer reference.
When was DCH-519 released?
2006, per multiple corroborated WebSearch results — not independently verified against a directly-fetched primary notification document this phase.
