 ABSTRACT

A field experiment was conducted at College of Horticulture, Bengaluru during July, 2014 to April, 2015. The study was conducted to investigate the effect of seasons and spacings on seed production of rose onion variety Arka Bindu. Two seasons (Kharif and Rabi) and four spacings (40cm x 30cm, 30cm x 20cm, 30cm x 15cm, 30cm x 10cm) were considered in the experiment. The number of scapes, length and thickness of the scape, umbel length and width, seed weight per umbel, seed weight per plant, total seed weight per plot and total seed weight per hectare were measured to assess the onion seed production with quality. The maximum number of scapes (5.29), length and thickness of flower stalk (72.67 cm and 7.60 cm) and umbel length and width (5.97 and 5.52 cm) were obtained from Rabi season crop with wider plant spacing of 40cm x 30cm. The results revealed that the highest seed yield of 917.60 kg was obtained with the spacing of 30cm x 15cm in Rabi season.  Hence, Rabi season with the spacing of 30cm x 15cm is found better for onion seed production in Eastern Dry Zone of Karnataka.

Key words: Season, Spacing, Kharif and Rabi.
