E-mail: dr_vktarti@yahoo.com Abstract A trial was conducted to assess the influence of NAA (5, 10 and 15 ppm), GA3 (25, 50 and 100 ppm), CCC (500, 1000 and 1500 ppm), BA (25, 50 and 100 ppm), boric acid (0.1 and 0.2%) and zinc sulphate (0.2 and 0.4%) on flowering and yield parameters of strawberry cv. Chandler. Aqueous solutions of these chemicals were sprayed on the plants before flower bud initiation stage i.e., 65 days after transplanting during the year 2000 and 2001. When the data for both years were pooled, it clearly revealed that plants treated with GA3 at 100 ppm concentration took minimum number of days (89.00 days) to produce first flower, enhanced flowering for longer duration (72.66 days) with maximum number of fruits (14.25) per plant. As regard duration of harvesting and yield is concerned, the maximum duration of harvesting (109.91 day) with maximum yield (112.95 g) per plant were also recorded from the plants treated with GA3 at 100 ppm concentration. On the other hand, plants treated with CCC at 1000 ppm produced the maximum number of flowers per plant (16.06) followed by GA3 at 100 ppm.
