RD 2552
A widely grown feed and food variety for the North-Western Plains Zone under irrigated conditions, valued for a dependable yield rather than any malt premium. Not yet individually researched for a detail page.

About this variety
RD 2552 is a dual-purpose barley variety recommended for the North-Western Plains Zone (NWPZ) under irrigated, timely-sown conditions. ICAR-IIWBR Karnal's own Barley Improvement page, directly fetched this phase, confirms it as a dual-purpose release: it can be cut for green fodder 50–55 days after sowing in the plains, after which the regenerated crop is left to mature for grain — a cut-and-regrow use this record's own "feed and food" description doesn't spell out. Yield figures repeated across several secondary sources (WebSearch-summarized, not independently fetched and read this phase) put it at roughly 46.10 q/ha for irrigated, timely-sown NWPZ conditions and about 38.4 q/ha in the North-Eastern Plains Zone.

Management notes
- Can be cut for green fodder 50–55 days after sowing in the plains; the regenerated (ratooned) crop is then left to mature for grain — a dual-purpose cut-and-regrow use documented directly on ICAR-IIWBR Karnal's own Barley Improvement page
Advantages & considerations
Why farmers may choose it
- Confirmed dual-purpose use directly from ICAR-IIWBR Karnal's own page: cut once for green fodder around 50–55 days after sowing, then let the regenerated crop mature for grain — extra fodder value without a separate fodder-only planting
- Recommended across three states (Rajasthan, Haryana, Punjab) in this record, spanning both this record's own NWPZ yield band and, per secondary sources, a lower North-Eastern Plains Zone yield — suggesting broad zonal adaptability
Things to consider
- A government notified-varieties listing (found via WebSearch, not independently fetched and read as text this phase — the PDF could not be parsed) reports a notification number S.O. 340(E) dated 3 April 2000 for RD 2552; this date is not treated as confirmed here
- Corrected 2026-08-15: yieldPotential previously read 40–45 q/ha, a single band that didn't comfortably cover the two zone-specific figures reported for this variety — about 46.10 q/ha for irrigated NWPZ conditions and about 38.4 q/ha for the North-Eastern Plains Zone. Rather than picking one zone over the other, the field is now widened to 38–46 q/ha to span both.

Frequently asked questions
Is RD 2552 only a grain variety?
No — ICAR-IIWBR Karnal's own page describes it as dual-purpose: it can be cut once for green fodder around 50–55 days after sowing, and the regenerated crop is then left to mature for grain.
What zone is RD 2552 recommended for?
The North-Western Plains Zone (NWPZ), under irrigated, timely-sown conditions, per IIWBR's own Barley Improvement page — consistent with this record's Rajasthan/Haryana/Punjab states.
When was RD 2552 released?
Not confirmed this phase. A secondary government listing cites a notification dated 3 April 2000, but that document could not be independently fetched and read, so this date is reported as unverified rather than confirmed.
How does RD 2552's yield compare across zones?
About 46.10 q/ha in the irrigated North-Western Plains Zone and about 38.4 q/ha in the North-Eastern Plains Zone — this record's yieldPotential (38–46 q/ha) is set to span both zones rather than average them away.
Does RD 2552 have malt-grade quality?
No source checked this phase describes RD 2552 as a malt-grade variety — it is documented as a food-and-fodder dual-purpose type, unlike the malt-focused DWRB series from the same institute.
