Abstract
An experiment was conducted under protected condition to study the effect of foliar application of GA 3 (100 and 150 ppm), urea (1.0 and 1.5 %) and ZnSO 4 (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 GA 3 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, GA 3 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 GA 3 promote vegetative growth and moderate concentration significantly controls flowering and yield attributes in case of strawberry.
