About this variety

Jawahar Isabgol-4 (JI-4) was released in 1996 by the College of Horticulture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya (RVSKVV), Mandsaur, Madhya Pradesh. It has narrow, dense, hairy dark-green leaves and a boat-shaped, hard, light-pink seed with a rosy-white husk — a fairly distinctive physical description among the named isabgol varieties. Its documented yield potential, 1,300–1,500 kg/ha, is among the highest figures recorded for a named variety on this page, making it a reasonable choice for a grower prioritising yield where JI-4 seed is genuinely available. Its exact duration is not separately documented in the sources checked for this page, so a grower should confirm the local sowing-to-harvest window with their nearest Krishi Vigyan Kendra before planning around it.
