Title : Influence of irrigation scheduling based on IW:CPE ratio and stress mitigating chemicals on growth and yield of coriander (Coriandrum sativum L.) var Jawahar Dhaniya-10

Abstract :

In order to study the influence of exogenous application of stress mitigating chemicals such as salicylic acid, thiourea and KNO3 to alleviate moisture stress in coriander to improve the morphological and yield attributes through irrigation scheduling, an experimentation was conducted at Vegetable Research Centre, Department of Horticulture, JNKVV, Jabalpur (M.P.) during Rabi season for two consecutive years (2020-21 and 2021-22). The trial was laid out in split plot design with IW:CPE (0.6, 0.8, 1.0 and 1.2) as main plot and stress mitigating chemicals (SA, thiourea and KNO3) as subplot with different concentrations. The pooled analysis carried out during the study substantiated that coriander variety JD-10 sown under IW:CPE 0.8 gave better vegetative growth and higher yield as was superior over the others. Foliar application of SA@150ppm significantly enhanced the morphological traits and yield components thus giving a maximum yield of 18.47q/ha by producing more number of umbels, umbellets and seeds per plant. Treatment combination I2C2 (IW:CPE 0.8 with foliar application of salicylic acid @ 150ppm) gave better growth as plant height reached to 106.27cm at crop harvest with 7.02 branches plant-1, maximum seed yield of 14.92 g plant-1 and highest seed yield of 19.61q/ha. Seed yield was found to be in positive correlation with number of umbels plant-1, umbellets plant-1, seeds per umbel and seed yield plant-1. Thus it can be concluded that coriander produced under optimum soil moisture with ascribed irrigation level along with suitable dose of salicylic acid is optimum for coriander production and ensures higher yield.
