Abstract
An experiment entitled “Effect of different plant growth regulators and methods of application on growth and seed yield of coriander” was carried out during rabi season of academic year 2018-19, at Instructional Farm, Department of Vegetable Science, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.).
The experiment was conducted in Factorial Randomized Block Design with three replications and eighteen treatment combinations. There were two factors, main factor being methods of application of PGRs (three) viz. seed soaked, foliar spray, seed soaked + foliar spray and another sub factor was six concentrations of PGRs viz., GA3 (50, 75 and 100 ppm) and CCC (200, 250 and 300 ppm).
The data of experiment indicated that the factor, method of application of PGRs M3 – seed soaked + foliar spray recorded significantly maximum results for plant height (cm), number of branches per plant, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel, seed yield per plant (g), seed yield per plot (kg), seed yield per hectare (q), test weight (g), germination (%) and oleoresin content (%) whereas, significantly minimum results for days required to first flowering, days required to 50 % flowering and days required to harvesting.
The factor, concentration of PGRs P3 – GA3 @ 100 ppm showed significantly maximum results for plant height (cm), test weight (g), germination (%) and oleoresin content (%) and significantly minimum results for days required to first flowering, days required to 50 % flowering and days required to harvesting. Whereas, the concentration of PGRs P6 – CCC @ 300 ppm was giving significantly maximum results for number of branches per plant, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel, seed yield per plant (g), seed yield per plot (kg) and seed yield per hectare (q).
Interaction effect of different concentration of PGRs and methods of application was found significantly maximum with treatment combination M3P6 – CCC @ 300 ppm with seed soaked + foliar spray for plant height, number of branches per plant, number of umbels per plant, number of umbellets per umbel, number of seeds per umbel, seed yield per plant (g), seed yield per plot (kg) and seed yield per hectare (q), test weight (g) and benefit: cost ratio. The results of interaction effect of treatment combination M3P3 – GA3 @ 100 ppm as seed soaked + foliar spray was found significantly minimum in terms of days required to first flowering, days required to 50 % flowering and days required to harvesting. Whereas interaction effect for germination (%) and oleoresin content (%) was found to be non-significant.
