Abstract

The field experiment on plant growth and flower yield in African marigold (Tagetes erecta L.) by the application of plant growth regulators and pinchingwas carried out at Department of Horticulture, Faculty of Agriculture, Annamalai University, and Tamil Nadu during the period 2012-2013. The present investigation was laid out in Factorial Randomized Block Design (FRBD) replicated thrice with 14 treatments. Two F1 hybrids namely Gold Benz tall (V1) and Maxima yellow (V2) were taken for the study comprising GA3 @ 50, 100 and 150 ppm, NAA @ 50, 100 and 150ppm, MH @ 250, 500 and 750 ppm, Alar @ 200, 400 and 600 ppm and pinching with untreated control. The growth and quality characters were observed its superiority in Gold Benz tall with the combination of foliar spray of GA3 @ 150 ppm except number of laterals and number of flowers were registered Maxima yellow with the foliar spray of GA3 @ 150 ppm.
