ABSTRACT

The effect of gibberellic acid concentrations on fruit characters and yield of strawberry was studied on two varieties, namely ‘Sweet Charlie’ and ‘Winter Dawn’ during November, 2018 to March, 2019. Foliar application of three different concentration of GA3 viz. 50 ppm, 75 ppm and 100 ppm were done at 40 days and 60 days after planting. Experimental results showed that GA3 @ 75 ppm had the best effect to increase yield components and yield of both the varieties. Under GA3 @ 75 ppm, Winter Dawn exhibited higher fruit diameter (3.38cm) and fruit length (4.74cm) as compared to Sweet Charlie (3.28cm fruit diameter and 4.60cm fruit length). Though the fruit weight was slightly higher in Sweet Charlie (18.36g) as against Winter Dawn (17.90g) under the best treatment i.e. 75 ppm GA3 the yield recorded was higher in Winter Dawn (573.62g/plant and 24.04t/ha) as against Sweet Charlie (445.43g/plant and18.73t/ ha) due to higher number of fruits (32.44/plant) produced by Winter Dawn as compared to Sweet Charlie (24.94/plant). So, Winter Dawn variety produced 28.35% higher yield as compared to Sweet Charlie under GA3 @ 75 ppm treatment.
