JBO 2003 H (Ira)
This is a tossa jute (Corchorus olitorius) release — the 'JBO' prefix marks CRIJAF's tossa releases (white-jute releases use 'JRC'). Recommended for late sowing because of its bred-in resistance to premature flowering, not because of any special waterlogging tolerance — general sourced guidance says tossa jute, unlike white jute, does not tolerate waterlogging well.

About this variety
JBO 2003 H (Ira) is a tossa jute (Corchorus olitorius) release — a directly-fetched technical presentation classifies it explicitly as 'Corchorus olitorius (Tossa jute)', and a separately-fetched peer-reviewed paper (PMC) confirms CRIJAF's 'JBO' prefix marks its C. olitorius breeding lines, sharing this record's own premature-flowering resistance and fibre-quality traits. Reported released 2007 by ICAR-CRIJAF, Barrackpore, with a reported cross of ('JRO 632' × 'Sudan Green') × 'Tanganyika 1'. The same presentation reports a fibre yield of about 38 q/ha — above this record's own 25–30 q/ha figure — and describes it as resistant to premature flowering, with better fibre quality and better biotic resistance to stem rot, root rot, anthracnose and yellow mite, closely matching this record's own diseaseResistance field with yellow-mite tolerance as an addition.
Key characteristics
Sowing & cultivation
- Seed rateGeneral tossa-jute guidance suggests about 3.0–3.5 kg/ha in line sowing (as opposed to the higher 4.0–4.5 kg/ha used for white/deshi jute) — not confirmed as JBO 2003 H-specific
- HarvestingReported fibre yield of about 38 q/ha, above this record's own 25–30 q/ha figure, per a directly-fetched technical presentation
Yield & maturity
Maturity period
100–120 days
Expected yield
25–30 q/ha dry fibre
Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.
Pest & disease considerations
Advantages & considerations
Why farmers may choose it
- Reported fibre yield of about 38 q/ha, the highest reported this phase among the two jute records researched
- Resistant to premature flowering, with better biotic resistance to stem rot, root rot, anthracnose and yellow mite than older releases
Things to consider
- A directly-fetched technical presentation explicitly classifies JBO 2003 H as 'Corchorus olitorius (Tossa jute)', and a separately-fetched peer-reviewed paper (PMC) confirms CRIJAF's 'JBO' prefix marks its tossa (C. olitorius) breeding lines, distinct from the 'JRC' prefix used for white-jute releases — corroborated across independent WebSearch hits (CRIJAF's own site, crijaf.icar.gov.in, and the AICRP jute-network site could not be reached directly to confirm, both returning DNS failures consistent with the ICAR-domain pattern seen throughout this rollout). Soil is set to loam, matching this variety's sibling record JRO 204 and general tossa guidance — no cultivar-specific soil source was found for JBO 2003 H itself. The late-sowing recommendation in the top-level note is supported by this variety's own premature-flowering resistance (see diseases below), not by waterlogging tolerance — general sourced guidance says tossa jute, unlike white jute, does not tolerate waterlogging well.
- Release year (2007) and parentage rest on WebSearch corroboration only — CRIJAF's own site (crijaf.icar.gov.in) and the AICRP jute-network site could not be reached to confirm directly (DNS failures). One secondary WebSearch hit instead cites 2008, and another states PPV&FR registration was still 'under process' with DUS testing completed at the time reported — the exact formal release/notification date remains unconfirmed.

Frequently asked questions
Is JBO 2003 H a white jute or tossa jute variety?
It's tossa jute (Corchorus olitorius). A directly-fetched technical presentation explicitly classifies JBO 2003 H as 'Corchorus olitorius (Tossa jute)', and a separately-fetched peer-reviewed paper confirms CRIJAF's 'JBO' prefix marks its tossa breeding lines (white-jute releases instead use the 'JRC' prefix).
How much fibre yield does JBO 2003 H give?
A directly-fetched technical presentation reports about 38 q/ha, above this record's own 25–30 q/ha figure — stated here as the sourced number rather than picked over the record's own, since the source is a general technical presentation rather than an official CRIJAF release document.
