Abstract

Aim: To study the effect of planting dates on seed quality of onion varieties.

Study Design: Split plot design and FCRD.

Place and Duration of Study: Agricultural Research Station, Hagari, University of Agricultural Sciences, Raichur (Karnataka) during Rabi 2023-24.

Methodology: Two varieties as main plot with five planting dates as sub plots.

Results: The results revealed that significantly highest seed germination (89.3 %), shoot length (8.97 cm), root length (7.02 cm) and seedling vigour index I and II (1428 and 1294, respectively) in D1 (1st fortnight of November). While, lowest seed germination (84.7 %), shoot length (7.65 cm), root length (6.04 cm), and seedling vigour index I and II (1250 and 1047, respectively) in D5 (1st fortnight of January). Among the varieties, Bhima super (V2) registered significantly highest seed germination (87.8 cm), shoot length (8.49 cm), root length (6.18 cm), and seedling vigour index I and II (1291 and 1116, respectively). Whereas, lowest seed germination (86.5 cm), shoot length (8.07 cm), root length (5.89 cm), and seedling vigour index I and II (1209 and 978, respectively) recorded in Bellary red (V1).

Conclusion: The results of present investigation revealed that, bulbs planted during 1st fortnight of November and Bhima super were found to be superior for high quality seed production of onion.

Keywords: Planting dates, onion varieties, seed germination and seed moisture
