About this variety
Pusa Sweti is an Asiatic (desi) turnip released by ICAR-IARI, New Delhi; a course deck gives 1976 and says it was selected from germplasm collected in Punjab. NHB describes attractive pure white roots that mature 45 to 50 days after sowing and average 20 to 30 t/ha, and the TNAU lecture note calls it a very early variety suited to October sowing in the plains. Roots are round to flattish round, medium sized and tender with white flesh, and the mild flavour suits everyday cooking. An Asiatic type stands warmer weather better than a European turnip, but it is still a cool-season crop. It does not keep as long as a yellow-fleshed or European type, so sell it within days of pulling.
Should you pick this variety?
Choose Pusa Sweti when you want a fast white desi turnip and plan to sell it fresh. The National Horticulture Board (NHB) lists it for October sowing, 45 to 50 days to harvest and 20 to 30 t/ha; a course slide deck says it was released by IARI in 1976 as a selection from Punjab germplasm and suits August to September. Sources disagree on the month, so take it from your local advice. In a 2020 trial of 12 turnip genotypes at Neri, Himachal Pradesh, it gave the best root yield with leaves (200.66 g a plant) against a Purple Top White Globe check. If you need roots to keep for weeks, a yellow-fleshed or European type suits better.
Sowing & cultivation
- Sowing timeOctober in the plains (NHB, TNAU); PAU advises August to September for desi turnips, so confirm the month locally
- Seed rate2–3 kg an acre (about 5–7.5 kg/ha) per the PAU package; thin early to the spacing below
- SpacingRows 30 cm apart; plants thinned to 8–10 cm apart in the row
Advantages & considerations
Why farmers may choose it
- Quick: 45 to 50 days (NHB), so it works as a catch crop between two main crops.
- Smooth, round, pure white roots with a mild flavour for everyday cooking.
- An Asiatic type, so it stands warmer sowing than a European turnip; the exact month needs local advice.
Things to consider
- Being an Asiatic type, it does not keep as long in storage as a European (temperate) turnip variety — best sold and eaten fresh within a few days of pulling.

Which month? What four sources say about sowing Pusa Sweti
NHB's variety sheet says Pusa Sweti suits sowing in October, and the TNAU eAgri lecture note says the same: a very early variety for October sowing in the plains. A course slide deck gives August to September with 40 to 45 days. PAU's package does not name Pusa Sweti but says desi (Asiatic) turnips are best sown in August to September and European types in October to November.
Why the gap? A turnip does best at 10 to 15 degrees C; long days and high temperature bring early bolting, and in hot weather the root turns fibrous, tough and pungent (PAU, TNAU). A sowing that is safe in a cool Punjab September can be too hot in the Bihar plains. So the month depends on when the heat breaks where you farm, not on the variety. A practical test is to sow three small strips a fortnight apart and keep notes on which gives clean, mild roots at 5 to 10 cm across.
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
Should I sow Pusa Sweti in August to September or in October?
The sources split. NHB and the TNAU eAgri lecture note say October sowing in the plains. A course slide deck says August to September. PAU says desi turnips are best sown in August to September and European types in October to November. A turnip likes 10 to 15 degrees C; long days and high temperature bring early bolting, and in hot weather roots turn fibrous, tough and pungent (PAU, TNAU). So sow when the heat has broken in your area and ask your KVK for the month they trust.
How many days and how much yield should I plan for?
NHB gives 45 to 50 days and an average of 20 to 30 t/ha. A course deck gives 40 to 45 days and about 250 quintals a hectare, which is 25 t/ha. So plan on 45 to 50 days and 20 to 30 t/ha, and pull by root size, not by the calendar: TNAU says harvest at 5 to 10 cm across, and roots turn tough and fibrous if you wait. We found no field trial from the plains that measures Pusa Sweti in t/ha.
How is Pusa Sweti different from Pusa Chandrima?
Both have white roots. Pusa Sweti is the quicker one: 45 to 50 days (NHB). Pusa Chandrima takes 55 to 60 days (NHB), and TNAU describes its roots as medium to large with an average of 400 quintals a hectare and sowing from October to December. If you want the earliest white turnip for a thin market, take Sweti. If you can wait 10 days for bigger roots, look at Chandrima.
Can I save seed from my own Pusa Sweti crop?
It is open-pollinated, and TNAU says Asiatic turnips set seed in the plains. Pick true-to-type roots, trim the root tip, keep about a third of the crown, and transplant at 45 x 35 cm. Turnip is cross-pollinated, so keep 1,000 to 1,600 m from other turnips, Chinese cabbage and mustard. TNAU quotes a seed yield of 5 to 6 quintals a hectare and says to harvest when 70% of pods turn light yellow. Mustard fields nearby make this hard, so many farmers buy fresh seed.
Is there any independent trial of Pusa Sweti?
One that we found: a 2021 master's thesis from Dr YS Parmar University, Neri (Hamirpur), Himachal Pradesh, which grew 12 turnip genotypes in the 2020 rabi season. Pusa Sweti gave the best average root yield with leaves, 200.66 g, and the line T-COHF-NERI-5 (185.77 g) was statistically at par. It is one season at one hill location and gives grams a plant, not tonnes a hectare, so treat it as a hint that the variety is sound, not as a yield promise for the plains.
