About this variety
DWRB 182 is a two-row malt barley from ICAR-IIWBR (Indian Institute of Wheat and Barley Research), Karnal. It is bred for irrigated, timely-sown fields in the North Western Plains Zone. IIWBR's Barley Improvement page lists it among the institute's recent high-yielding two-row malt varieties for this zone. A malt barley is grown to a maltster's protein and grading specification, not for grain yield alone. IIWBR's page does not give a release year, parentage, yield or days to maturity for it.
Should you pick this variety?
Choose DWRB 182 if you irrigate in Punjab, Haryana or western Uttar Pradesh, sow on time and have a maltster to sell to. ICAR-IIWBR lists it among its two-row malt barleys for the North Western Plains. A malt crop is paid for protein and grain size, not weight alone, so settle the buyer before you buy seed. Choose RD 2552 instead if you have no malt buyer and want grain plus a green-fodder cut. Choose DWRB 223 if you want hulless grain for food. Its newer siblings DWRB 160 and DWRB 219 report about 53.7 and 54.49 q/ha, so ask what the maltster near you prefers.
Sowing & cultivation
- Sowing time15 October to 15 November gives the best result, and yield falls gradually as sowing slips towards the end of December (PAU package for Punjab)
- Seed rate35 kg of seed an acre for a timely sown irrigated crop, and 45 kg an acre if sowing is late or the crop is rainfed
- SpacingRows 22.5 cm apart for a normally sown crop, and 18–20 cm apart for a late-sown crop
- FertilizerWith no soil test, on medium-fertility soil give 25 kg N and 12 kg P2O5 an acre (55 kg urea and 27 kg DAP; use 45 kg urea if you give the DAP), drilled at sowing. Add 6 kg K2O (10 kg muriate of potash) an acre only on soil that tests low in potash
Advantages & considerations
Why farmers may choose it
- Bred specifically for the irrigated, timely-sown regime of the North-Western Plains Zone, matching the malt-quality tier ICAR-IIWBR targets in this NWPZ series
- Part of ICAR-IIWBR Karnal's continuing line of two-row malt barley releases for India's brewing and malt industry, alongside named siblings such as DWRB 160 ("Karan Maltsona") and DWRB 219
Things to consider
- IIWBR's page confirms the name and the zone, but gives no release year, parentage, yield or days to maturity. The 45–50 q/ha and 120–125 days shown above are approximate, so ask your seed supplier or KVK for the released figures.
- Newer malt barleys from the same institute report higher yields: DWRB 160 (Karan Maltsona, released 2019) about 53.7 q/ha with 92% bold grain, and DWRB 219 (released 2024) about 54.49 q/ha, 132 days to maturity and 11.4% protein. These Tribune figures are for those varieties, not for DWRB 182.

Settle the malt buyer before you buy seed
A malt barley is bought against a specification: grain size, protein level and a clean, even lot. The price depends on passing it, not on weight alone.
So settle three things before sowing: who will buy, what protein and grading they want, and when they take delivery. Ask for the terms in writing.
Keep this crop apart from feed barley at harvest and threshing, so one lot is not mixed with another. If you cannot find a buyer, RD 2552 is the safer variety to sow.
Can you keep your own planting material?
This is an open-pollinated variety, so seed from a healthy crop of your own can be sown again. Keep seed only from disease-free plants, dry it properly, store it cool and dry, and bring in fresh certified seed every three to four years so the variety does not drift.

Frequently asked questions
Is DWRB 182 suitable for rainfed cultivation?
No. It is bred for irrigated, timely-sown fields in the North Western Plains Zone, and IIWBR describes it only as an irrigated malt variety.
Is DWRB 182 a malt barley or a feed/food barley variety?
Malt barley — ICAR-IIWBR's own Barley Improvement page lists it among the institute's two-row malt varieties, grown against a maltster's protein/grading specification rather than for grain yield alone.
What states is DWRB 182 recommended for?
The summary above lists Punjab, Haryana and Uttar Pradesh, consistent with IIWBR's North-Western Plains Zone recommendation for its irrigated two-row malt varieties.
What is the exact release year of DWRB 182?
IIWBR's page does not give one. If a seed seller quotes a year, ask for the notification number before you rely on it.
Does DWRB 182 have any disease resistance?
It is rated resistant to yellow rust. IIWBR's page does not give a rust rating for DWRB 182, so treat the rating as the variety's reputation and still check the crop in cool, humid weather.
Is DWRB 182 better than RD 2552?
They do different jobs. DWRB 182 is a two-row malt barley, so it earns its money from a maltster. RD 2552 is a dual-purpose barley that gives a green-fodder cut and then grain. With a malt buyer, pick DWRB 182. Without one, RD 2552 is the safer pick.
Can I cut DWRB 182 for green fodder?
IIWBR's page mentions the green-fodder cut at 50–55 days only for the dual-purpose barleys, RD 2035 and RD 2552. DWRB 182 is a malt type, so grow it for grain.
What yield and days should I plan on for DWRB 182?
IIWBR's page gives no yield or days figure for it. The 45–50 q/ha and 120–125 days shown here are approximate. Plan on the lower end, and ask your seed supplier for the released figures.
Should I look at DWRB 160 or DWRB 219 instead of DWRB 182?
Compare them with your maltster in mind. Newer malt barleys from the same institute report higher yields: DWRB 160 (Karan Maltsona, released 2019) about 53.7 q/ha with 92% bold grain, and DWRB 219 (released 2024) about 54.49 q/ha. The 45–50 q/ha shown for DWRB 182 is approximate, so ask what grade the maltster near you prefers before you choose.
What should I ask a maltster before sowing DWRB 182?
Ask which variety and grade they accept, what protein and grain size they want, and whether the price is fixed before harvest. A malt crop is paid for protein and grain size, not weight alone. Settle the buyer before you buy seed. Without a malt buyer, RD 2552 gives grain plus a green-fodder cut instead.
