The studies were carried out to determine the effect of sowing dates (5, 15 and 25 October, and 5 November) and planting methods (direct sowing and transplanting) on quality of seed produced by different order umbels in fennel at Hisar, Haryana, India, during 1996-97 and 1997-98. The results indicated that the percentage contribution to seed yield of fennel was highest from primary umbel followed by secondary umbel, whereas main and tertiary umbels contributed little. Early sowing/planting produced the highest seed quality in term of test weight, germination and vigour index. Main umbels produced the best quality seeds followed by primary, secondary and tertiary umbels. Transplanted crop produced bolder seeds which had higher test weight, germination percentage and vigour index compared to direct sown crop.
