dc.description.abstractAn experiment titled “Performance of radish (Raphanus sativus L.) as influenced by sowing dates and varieties” was carried out in the Experimental Farm, Department of Horticulture, Assam Agricultural University during 2016-2017 with the objectives: to evaluate the effect of sowing date and variety on growth, development, yield and quality. The experiment was laid out in split–plot design with three main plots and five sub- plots which was replicated three times. Three varieties i.e., V1 (Japanese White), V2 (Pusa Chetki) and V3 (Chinese Pink) were allotted as main plot and five sowing dates i.e., S1 (15th October), S2 (1st November), S3 (15th November), S4 (1st December) and S5 (15th December) were allotted randomly as sub-plots within the main plots. The mean performance for growth, development and yield characters revealed that S2 (1st November, 2016) sowing had recorded maximum for most of the growth as well as yield attributing characters viz., plant height (39.34cm), root length (31.49 cm), root diameter at top (5.20 cm), maximum root diameter at length (5.37cm), shoot weight (175.40 g), number of leaves (22.01), root weight (250.71 g) root yield ha-1 (818.06 q ha-1) and quality characters like dry matter content (19.29 g). Similarly S1 also recorded the highest quality characters viz., ascorbic acid content (18.71) and pungency (447.95μg 100g-1). S5 (15th December) sowing recorded maximum days to maturity (64.90) and fibre content (1.67g). In respect of variety, V2 (Pusa Chetki) had recorded maximum plant height (42.15), root length (27.52 cm), root diameter at top (4.65cm), maximum root diameter at length (4.77 cm), shoot weight (103.36g), number of leaves (21.98), root weight (167.04 g) root yield ha-1 (747.32 q ha-1) as well some quality characters like dry matter content (13.37 g), ascorbic acid (19.99 mg 100-1). V1(Japanese White) had recorded the maximum days to maturity (67.40), and pungency (510.71 μg 100g-1). Also V3 (Chinese Pink) had recorded the maximum root:shoot ratio (1.62). In case of interaction between sowing date and variety V2S2 (Pusa Chetki ) sown on 1st November had recorded maximum plant height (47.83 cm), root length (36.83 cm), root diameter (7.29 cm) at top maximum root diameter at length (7.79 cm), shoot weight (220.16 g), number of leaves (25.63), root weight (357.71cm), root yield per hectare (1003.33 q ha-1) and dry matter content of (28.91 g).While, V1S1 (Japanese white in 15th October) had recorded pungency of 560.87μg 100-1.V5S5 (Chinese Pink on 15th December) had the highest root:shoot ratio (2.05).V2S1 (Pusa Chetki) sown on 15th October showed the minimum days to maturity (41.03), highest ascorbic acid content(23.30 mg 100 g-1) and V1S5 (Japanese White on 15th December ) had recorded the maximum days to maturity(75.04) and fibre content (1.71mg 100 g-1 ). The cost economics indicated the superiority of V2S2 (Pusa Chetki on 1st November) with benefit cost ratio of 5.86 followed by the same variety with B:C of 5.54. Based on the results of the study, it was concluded that radish varieties, Pusa Chetki could be suggested as best suited for growing in Jorhat agro climatic zone of Assam and the ideal time for sowing these variety would be on 15th October to 1st November.
