Effect of gibberellic acid and salicyclic acid on growth and yield of statice (Limonium sinuatum)

A field experiment was carried out to study “the effect of GA₃ and salicylic acid on growth, f and yield of statice” at Horticulture Section, College of Agriculture, Nagpur during Rabi season 2022-23. The experiment was laid out in Randomized Block Design with three replications and seven treatments. The treatments comprised of different levels of gibberellic acid and salicylic acid along with control viz., GA₃ 50 ppm, GA₃ 100 ppm, GA₃ 150 ppm, salicylic acid 50 ppm, salicylic acid 100 ppm, salicylic acid 150 ppm and control as water spray. The treatments were imposed as foliar sprays twice at 30 and 45 days after transplanting. Results of the experiment revealed that application of GA₃ 150 ppm recorded significantly maximum plant height (26.40cm ), number of leaves plant^-1 (187.27), plant spread (46.70 cm) and leaf area (73.76 cm²), minimum days to flowering spike initation (72.55 days) with maximum spike length (52.41cm). The yield parameters, viz., number of spikes /plant ( 14.72) and spikes/ ha (8.17 lakh) were observed maximum with the treatment carrying foliar application of GA₃ at 150 ppm.
