Effect of different plant growth regulators and methods of application on growth of coriander (Coriandrum sativum L.)

Abstract

The experiment was carried out during rabi season of academic year 2018-2019 at Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola to study the effect of different plant growth regulators and methods of application on growth of coriander (Coriandrum sativum L.). The experiment conducted in factorial randomized block design with three replication and eighteen treatment combinations. There were two factors, main factor being methods of application of PGRs viz. seed soaked, foliar spray and seed soaked + foliar spray and sub factor was six concentrations of PGRs viz. GA3 (50, 75 and 100 ppm) and CCC (200, 250 and 300 ppm) growth parameters like plant height and number of branches per plant were influenced by M3 (seed soaked + foliar spray). The treatment combination M3P3 (GA3 @ 100 ppm as seed soaked + foliar spray) and M3P6 (CCC @ 300 ppm as seed soaked + foliar spray) recorded significantly maximum result in respect of plant height and number of branches per plant, respectively. Maximum plant height (75.11 cm) was recorded in M3P3 and maximum number of branches (9.61) were recorded in M3P6 treatment combination.
