About this variety
JRC-212, popularly called Sabuj Sona, is a white jute (Corchorus capsularis) variety from ICAR-CRIJAF, Barrackpore. The AINP list on jute and allied fibres gives its notification as S.O. 598(E) of 8 October 1974, together with JRC 321. It has non-shattering pods and is sown from mid-March to mid-April. The AINP list gives a fibre yield of 25 to 28 q/ha, and the Assam package of practices gives 22 to 26 q/ha, a sowing time of March to April and a suitability for mid and high land. The Assam package rates it moderately resistant to stem rot. TNAU also lists JRC 212 for Tamil Nadu.
Should you pick this variety?
Choose JRC-212 if you grow white jute on mid or high land that does not hold standing water, sow in mid-March to mid-April, and want a variety with a long record in Assam and West Bengal. It gives 25 to 28 q/ha on the AINP list. For low land that floods, JRC 321 is the white jute recommended. For a bigger fibre yield, the tossa varieties JRO 66 and JRO 8432 are listed at 35 to 40 q/ha, but tossa does not stand waterlogging.
Sowing & cultivation
- Sowing timeMid-March to mid-April (AINP); March to April (Assam package).
- Seed rateWhite jute (capsularis), Assam package: 6 to 7 kg/ha in rows or 10 to 11 kg/ha broadcast. TNAU: 7 kg/ha in rows or 10 kg/ha broadcast.
- SpacingAssam: rows 22 to 25 cm apart, plants 5 to 7 cm apart, thinned to 60 to 70 plants a square metre. TNAU: 30 x 5 cm.
- FertilizerAssam package for white jute: 40 kg N, 25 kg P2O5 and 30 kg K2O per hectare. Half the N and P2O5 and all the K2O at final land preparation, the rest at 4 to 6 weeks. Take off the nutrients in any cow dung or compost you add (5 t/ha is about 25 kg N).
- HarvestingCut at the small-pod stage. If rice follows, JRC 212 can be cut at 100 to 120 days. Bundle at 15 to 20 cm, leave standing 2 to 4 days to shed leaves, then ret for 10 to 30 days (Assam package).
Pest & disease considerations
Advantages & considerations
Why farmers may choose it
- Non-shattering pods and a long record in Assam and West Bengal.
- Moderately resistant to stem rot.
- Can be cut early, at 100 to 120 days, so rice can follow.
Things to consider
- Yield is lower than the tossa varieties on the AINP list (35 to 40 q/ha for JRO 66 and JRO 8432).
- Suited to mid and high land. For low land that floods, JRC 321 is the white jute recommended.
- Day counts here are crop-level figures. We found no JRC-212-only count.

From sowing to the rice crop: counting the days
JRC 212 is often grown ahead of rice, so the days decide when the rice goes in. The Assam package says jute is cut at the small-pod stage, and that if rice follows it can be cut as early as 100 to 120 days to leave time for ploughing. Count from your own sowing date. Sown on 15 March, 100 to 120 days is 23 June to 13 July. Sown on 15 April, it is 24 July to 13 August.
The fibre is not yet ready on those dates. After cutting, the bundles stand in the field for 2 to 4 days to shed leaves, and then ret in water for 10 to 30 days, depending on the water temperature. The Assam package puts the best water temperature at 32 to 34 degrees C. So fibre from a 15 March crop is out of the pond between about early July and mid-August, and fibre from a 15 April crop between about early August and mid-September.
This is why the March end of the window matters. A mid-March sowing frees the field for rice earlier and puts the retting in warm water. An April sowing is later, but it can suit a field that is still wet or was cleared late. Pick the date from the rice you plan to plant next and the water you will have for retting.
Can you keep your own planting material?
JRC 212 is an ordinary, non-hybrid variety, so seed from your own seed plot grows into the same type. A fibre crop is cut before the seed ripens, so seed has to come from a separate plot left to mature. Certified seed covers only about 35% of India's jute area, so ask the seed corporation or a certified producer first.

Frequently asked questions
What is the difference between JRC-212 and Sabuj Sona?
None. Sabuj Sona ("green gold" in Bengali) is the popular name for JRC-212, and the Assam package lists it as JRC 212 (Sabujsona). It is a white jute, Corchorus capsularis. The JRC prefix goes with white jute and JRO with tossa jute, Corchorus olitorius.
How much fibre does JRC-212 give?
The AINP list gives 25 to 28 q/ha, and the Assam package gives 22 to 26 q/ha. TNAU gives a fibre yield of 2.0 to 2.5 t/ha for jute in Tamil Nadu. Farm averages are lower than any of these: CRIJAF gives Odisha an average of 17.4 q/ha. Plan your income on the lower figure and treat the 28 as the best case.
Which land suits JRC-212?
Mid and high land, says the Assam package. TNAU adds that capsularis jute can grow even in standing water, especially late in its growth, but low land that floods deeply is where JRC 321 is recommended instead. Use loam or sandy loam, and add lime at 20 to 30 q/ha every 3 years where soil pH is below 5.5.
How do I protect JRC-212 from stem rot and root rot?
The Assam package rates JRC 212 moderately resistant to stem rot. It advises raising soil pH to 5.5 with lime, giving up to 50 kg K2O/ha, rotating jute with rice, and treating seed with Trichoderma at 5 g per kg to stop damping off and seedling blight. Moderate resistance is not immunity, so keep the field well drained and thin the plants to 60 to 70 a square metre.
