Growth Analysis of Coriander (Coriandrum sativum L.) as Influenced by Different Sowing Dates and Planting Geometry in Chhattisgarh Plains Zone

An experiment was conducted to assess the effect of different sowing dates and planting geometry on coriander during the winter seasons of 2020-21 and 2021-22 at Instructional farm, College of Agriculture and Research Station, IGKV, Raigarh, Chhattisgarh. The experiment was laid out in split-plot design, comprised of four date of sowing viz., D1: 25th October, D2: 10th November, D3: 25th November and D4: 10th December as 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 as sub-plot, and replicated trice. Influence of above treatments on crop was studied regarding growth parameters of coriander and analyzed statistically. The result showed that the crop sown on 25th October recorded significantly higher growth parameters viz., plant height, number of branches, dry matter accumulation, crop growth rate and relative growth rate. Among planting geometry, sowing of coriander at 30 x 12.5 cm spacing produced significantly taller plants, higher number of branches plant-1, dry matter accumulation plant-1, crop growth rate and relative growth rate. Coriander sown on 25th October interacted with the 30 x 12.5 cm spacing and registered significantly higher dry matter accumulation.
