PHENOLOGY AND YIELD OF CORIANDER AS INFLUENCED BY SOWING DATES AND IRRIGATION

Abstract

Effect of 3 irrigations viz., 15 + 30 + 45 + 60 + 75 + 90 + 105 DAS + seed set (I1), 15 + 30 + 45 + 60 DAS + seed set (I2), 15 + 30 DAS + seed set (I3) alongwith 6 sowing dates viz., 5^th,12^th,19^th, 26^th November, 3^rd and 10^th December were studied on coriander based on a RBD with 3 replications in HRS, Mondouri, BCKV, India. A delay in sowing from November 5 to December 10 decreased growth and influenced phenology. November 5 exhibited significant improvement in yield attributes namely umbel and umbellets plant^-1(25.58 and 6.85), seeds umbel^-1 (30.55), test weight(12.61 g), seed weight plant^-1 (6.85 g), essential oil (o.25%-0.33%) and yield hectare^-1(1098.33 kg ha^-1). Similarly irrigation influenced plant height at 60 DAS (19.45 cm - 25.28 cm), 90 DAS (64.26 - 76.93 cm) and harvesting (80.16 cm- 97.59 cm), number of primary branches (6.69-7.37), 50% germination (10.28-11.03 days), flower initiation (60.19-63.94 days), 50% flowering (71.56-75.06 days) and fruit maturity(127.61-139.44 days). It can be concluded that the optimum date of sowing viz.5^th November along with irrigation level viz.I1 showed best results for important growth parameters and all yield attributes and quality characters of coriander.
