Abstract

The experiment was carried out at Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat (Assam) during 2015-17. The experiment was laid out in Factorial Randomized Block Design with three replications comprising 15 treatment combinations of five different concentration of gibberellic acid (GA3 0ppm, 50ppm, 100ppm, 150ppm and 200ppm) and three pinching levels viz., no pinching, pinching at 20 days and pinching at 40 days after transplanting (DAT). The result indicated that the important growth characters were significantly influenced by gibberellic acid and pinching treatments. The application of GA3 at 200 ppm recorded significantly higher plant height (85.36cm), number of primary branches (15.65branches/plant), stem diameter (1.37 cm), root volume (70.92 cc) and chlorophyll content (1.34mg g-1FW). Among the pinching treatments, pinching at 40 DAT recorded significantly lower plant height (72.01cm), maximum number of primary branches (15.95 branches/plant), highest stem diameter (1.35 cm) and maximum root volume (69.77 cc); whereas maximum plant height (86.61 cm) was found under no pinching. As far as flowering characters are concerned, number of flowers per plant (63.80), number of petals per flower (318.06), diameter of flower (4.55cm) and flower yield per plant (206.45g/plant) was significantly increased by the application of GA3 at 200ppm. The self life (7.38days) and storage life as garland (6.99days) were also improved with the application of 200ppm GA3. Among the pinching treatments, pinching at 40 DAT recorded highest number of flowers per plant (62.78), highest number of petals (317.20), maximum flower yield per plant (206.55g/plant),maximum self life of loose flower (7.21 days) and highest storage life as garland (7.04days) followed by pinching at 20 DAT. The combination of pinching at 40 days after transplanting along with foliar spray of gibberellic acid at the rate of 200ppm gives the highest benefit cost ratio (2.340).

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
