*Gibberellic acid used in the present investigations was very kindly supplied by Merck Sharp and Dohme International Co., U.S.A.
(1) The strawberry variety ‘Pusa Dwarf Early’ was sprayed with gibberellic acid (GA) and p-chlorophenoxyacetic acid (C1PA) at 5 and 10 ppm twice, as whole plant sprays.
(2) GA sprays increased the height of plants, length of peduncle and fruit-bud formation significantly over rest of the treatments including control.
(3) GA 5 and 10 ppm increased the total yield per plant by 48 and 62 per cent respectively over control.
(4) GA was much more effective in increasing total yield than C1PA when-used at the same concentrations.
(5) CIPA (10 ppm) resulted in early fruit maturity by five days but GA (10 ppm) extended the fruiting period by 8 to 10 days.
(6) GA and CIPA sprays did not adversly affect the fruit quality.
