Abstract:
A field experiment was conducted at MARS, UAS Dharwad to study the “Effect of dates of sowing on seed yield and quality of Chia” during Rabi 2022-23. The experiment was laid out in factorial randomized complete block design with three replications. There were eight treatment combinations comprised of four sowing dates under different fortnight intervals (first and second fortnight of October and November) & two varieties (CHIAmpion W-83, CHIAmpion B-1). Between the varieties, CHIAmpion W-83 has recorded significantly highest seed yield (301.40 kg/ha) compared to CHIAmpion B-1 (218.59 kg/ha). Among the dates of sowing seeds sown during first fortnight of October recorded significantly highest seed yield (354.93 kg/ha) compared to second fortnight of November (202.66 kg/ha). Among interactions, V₁D₁ recorded significantly highest seed yield/ha (397.10 kg/ha) and seed germination (90.33%), root length (4.65 cm), shoot length (9.35 cm), seedling dry weight (1.25 g), seedling vigour index – I (1264), lower electrical conductivity (0.34 dsm^-1), field emergence (80.33%) compared to delayed sowing dates.
