Effect of Sowing Time on Different Radish Varieties (Raphanus sativus L.)

Abstract

An experiment was conducted in Guru Kashi University research farm during the rabi season of the year 2019–20 to study the effect of sowing time on different radish varieties (Raphanus sativus L.). The experiment was laid out in randomized block design and replicated thrice. Seeds of the cultivars viz., Japanese White, Mino Early, INARA, Durga, Punjab Safed, Super Hill Queen and Pusa Chetki were sown on two different dates i.e. October 15th, and November 15th. According to varieties, Japanese White showed minimum average days to germination (5.20 d), although, maximum average root shoot ratio 3.17, average marketable yield per hectare 43t, maximum average plant height 81.07 cm and average root length 31.45 cm were observed in Durga. Maximum average leaf length 50.07 cm, the average number of leaves 15.27, average foliage weight 274.07 gm, average plant weight 550.14 gm, average root diameter 5.37 cm, average root weight 276 gm and average total yield per plot 59.23 kg, average marketable yield per hectare 53.33 ton were obtained in Punjab Safed variety. The combined effect of sowing dates and varieties showed that sowing of Punjab Safed on Oct 15th gave superior results for most of the growth and yield characters whereas, due to varietal differences Super Hill Queen exhibited inferior results on both the sowing dates.
