Abstract:
A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Jaipur) during rabi season 2016-17 to study the effect of stress mitigating chemicals on coriander varieties (Coriandrum sativum L.) grown on irrigated loamy sand soil of semi-arid eastern plain zone of Rajasthan. The experiment consisting of four varieties (RCr-435, RCr-728, RCr-436 and RCr-41) and six stress mitigating chemicals (water sprayed control, salicylic acid @ 100 ppm, thiourea @ 500 ppm, kinetin @ 30 ppm, DMSO @ 78 g ha^-1 and TGA @ 100 ppm at 40 and 60 DAS) making 24 treatment combinations were replicated three times in randomized block design. The results indicated that highest values of growth, yield attributing parameters, grain (14.82 q ha^-1) and stover yield (42.03 q ha^-1) were obtained with variety RCr-728. Among different PGRs applied, foliar spray of 500 ppm thiourea, being at par with salicylic acid, was found most effective and significantly increased the growth parameters viz., plant height, branches plant^-1, dry matter accumulation (metre^-1 row length), yield attributes (umbels plant^-1, umbellets umbel^-1 and seeds umbel^-1), seed (15.19 q ha^-1), straw (42.22 q ha^-1) and biological yields (57.41 q ha^-1), protein and essential oil content in seed as compared to other stress mitigating chemicals.
