Abstract: This study aims to determine the effect of concentration and time of application GA3 on growth and yield of strawberries, as well as to obtain the treatment that gives the results of the best fruit on the plant strawberries. This research was conducted in the village Sirahkincong Gandusari Blitar in March to June 2015. The experiment was arranged in a randomized block design (RAK) as factorial consisting of 2 factors with 3 replications, where the concentration of GA3 as a factor I consists of 4 levels ie GO: 0 ppm, G1: 25 ppm, G2: 50 ppm, G3: 75 ppm. The second factor is the timing of application GA3 consists of three levels ie: W1: 14 DAP, W2: 21 DAP and W3: 28 DAP. Observation of the plant include: plant height, number of leaves per plant, leaf area, flower emergence periode, flower number per plant, fruit number per plant, weight fresh fruit per plant. Results showed treatment concentration and time GA3 there is’tsignificant interaction on all of observation parameter. GA3 treatment 25 ppm could boost growth plant ie plant height, leaf number and area leaves compared to controls. GA3 25 ppm is effective to increase the amount of fruit and fresh fruit weight per plant than without GA3 (control) . Treatment time of GA3 on 12 DAP and 28 DAP can increase the number of fruit per plant but did not increase the weight fresh fruit crop.
Keywords: Concentration GA3, time ofapplication GA3, strawberry plants
