Shekhar-3

Shekhar-3, also catalogued as KU 309, was released in 2004 by Chandra Shekhar Azad University of Agriculture and Technology (CSAUAT), Kanpur, for general cultivation in Uttar Pradesh. Sourced material describes it as resistant to yellow mosaic virus, leaf crinkle and, notably, also Cercospora leaf spot and powdery mildew — a broader resistance package than this page's existing "YMV & leaf crinkle" field, which could reasonably be extended. Reported yields range from about 10 q/ha (in the original CSAUAT release figures) to 12–13 q/ha in some later agronomic write-ups, maturing in a fairly wide 66–84 day window depending on the source, both broadly consistent with this page's existing "Medium–high" yield rating and 75–80 day duration band. One geographic point worth noting: CSAUAT is headquartered in Kanpur, in central Uttar Pradesh, which sits at some distance from the "eastern UP" framing in this page's existing note — the variety may well have found its strongest adoption in eastern districts even though its home institute is centrally located, but no source directly confirmed an eastern-UP-specific recommendation.

Actual yield depends on sowing time, soil, irrigation, weather, seed quality and crop management.

• Uttar Pradesh

• Pant U 31

  From Pantnagar — the standard kharif urad across the eastern Gangetic plain.

• TAU 1 (Taru)

  From CCS HAU Hisar — a wider disease-resistance stack than Pant U 31, at a few days more duration.

• IPU 02-43

  From ICAR-IIPR Kanpur — a South Zone release with a wider resistance stack (MYMV plus powdery mildew) than most northern urad varieties, at a shorter 70–72 day duration.

• IPU 94-1 (Uttara)

  From ICAR-IIPR Kanpur — an older (1999), widely-adopted release for the North West and North East Plain Zones, with black seed, an attractive plant type and a 100-seed weight of about 3.6 g.

• Mash 338

  Popular in the north-west; tolerates YMV and gives bold grain. Not yet individually researched for a detail page.

  Open crop guide

• T-9

  An old, widely adapted variety — high-yielding but susceptible to YMV, so best where whitefly pressure is low. Not yet individually researched for a detail page.
