Abstract :
An experiment was conducted under protected condition to study the effect of foliar application of GA3 (100 and 150 ppm), urea (1.0 and 1.5 %) and ZnSO4 (0.5 and 1.0 %) on growth and yield of strawberry (Fragaria x ananassa Duch.) cv. Sweet Charlie. The results revealed that the applications of GA3 at 150 ppm significantly influenced the growth related parameters viz., highest plant height (18.34 cm), maximum numbers of runners/plant (10.31), highest length of runners/plant (39.76 cm) and maximum number of leaves/plant (36.70) whereas, GA3 at 100ppm significant effect on flowering parameters viz., minimum days to flowering (71.55), maximum number of flowers per plant (19.77) and maximum fruit set/plant (91.80 %) and yield parameters like, maximum number of fruit per plant (18.15), highest yield/plant was 0.17 kg and yield/plot was 4.19 kg. Therefore, from present investigation it can be emphasized that high concentration of GA3 promote vegetative growth and moderate concentration significantly controls flowering and yield attributes in case of strawberry.
