Abstract
A field experiment was carried out during the rabi season of 2020-21 and 2021-22 at Instructional farm, College of Agriculture and Research Station, IGKV, Raigarh, Chhattisgarh to find out the influence of different sowing dates and planting geometry on coriander. The experiment was laid out in split plot design with sixteen treatment combinations of main and sub plots, replicated trice. Four Dates of sowing viz. D1: 25th October, D2: 10th November, D3: 25th November and D4: 10th December were arranged in main plot and four planting geometries viz., S1: 30 x 5 cm, S2: 30 x 7.5 cm, S3: 30 x 10 cm and S4: 30 x 12.5 cm were taken as subplot treatments. Results revealed that coriander sown on 25th October registered significantly yield attributing characters viz., number of umbels plant-1, number of umbellets umbel-1, number of umbellets plant-1, number of seeds umbel-1, number of seeds umbellet-1, length of umbel, diameter of umbel, weight of umbels, test weight, seed yield plant-1 and seed yield ha-1. Among planting geometry, sowing of coriander at 30 x 12.5 cm spacing produced significantly higher values of aforesaid characters except for seed yield ha-1, which was maximum under 30 x 10 cm spacing. The interaction effect of 25th October coupled with the spacing 30 x 12.5 cm produced significant maximum seed yield plant-1.
