“…This might be due to the fact that application of gibberellin increases the vegetative growth viz., number of leaves, crown and leaf area which facilitates accumulation of more photosynthates leading to production of more number of runners per plant. This is in conformity with the findings of Braun and Kender (1985) [6] , Adams et al (1975) [1] , Singh and Tripathi (2010) [17] , and Paikra et al (2018) [12] in strawberry crop.…”

A pot experiment was conducted to study the influence of foliar nutrients and plant growth regulators on growth and yield of Strawberry (Fragaria × ananassa Duch.) under naturally ventilated polyhouse. The experiment was laid out in Completely Randomized Design with eleven treatments and three replications. Results of the study revealed that the application of GA3 150 ppm (T9) showed maximum plant height (19.21 cm), plant spread in north-south and east-west direction (28.15 cm and 24.79 cm respectively.), number of trifoliate leaves (25.20), maximum number of crowns per plant (4.93), leaf area (127.78 cm 2 ) and leaf area index (3.94), maximum number of runners per plant (5.29), minimum number of days taken for flowering (85.81 days), highest number of flowers (28.00) and fruits per plant (19.08), maximum yield per plant (299.36 g). Application of boron 0.6 per cent (T7) showed maximum fruit length (4.18 cm), fruit diameter (3.90 cm), fruit circumference (11.15 cm), maximum fruit weight (17.22 g) and fruit volume (21.78 cc).

“…This might also be due to the fact that gibberellins cause the elongation in internodal length. The research findings of Dubey et al (2017) [10] and Paikra et al (2018) [12] in strawberry are in support with the present findings.…”

“…The maximum fruit yield (321g) per plant was found in sawdust mulch plants treated with GA 3 , whereas the minimum fruit yield (118g) was found in black polyethylene with no GA 3 (Figure 1D). Paikra (2018) found that the GA 3 gave best result in terms of plant growth, yield and fruit quality of strawberry as compared to other treatments. The increase in yield could be a reflection of the effect of GA 3 on growth and development following cell division and elongation and had also an indirect effect on the auxin metabolism and resulted higher number of marketable fruits and thereby increased the fruit yield.…”

Plant growth regulators in combination with mulch materials have been shown to regulate physiological processes related to plant growth and development. The experiment was conducted to investigate the responses of different mulch materials and GA3 on plant morphological, physiological and yield attributes of strawberries during the period from November 2020 to March 2021. The experimental treatments included three different mulch materials: black polythene, white polythene, saw dust, and control (no mulch); and GA3 (0 and 200 ppm) were studied. According to the findings, strawberries grown with sawdust and GA3 had the highest chlorophyll content (SPAD value) (48.23), relative water content (76.45%), leaf area (48.23 cm2), maximum number of fruits (19.66) and fruit yield (321 g/plant). In contrast, individual fruit weight (18g) was the highest for plants grown in sawdust without GA3. Black polythene mulch showed no satisfactory improvement in the growth and yield characteristics of strawberry plants. Therefore, sawdust based mulching and GA3 may be recommended to obtain better strawberry growth and yield.

“…Jamal Uddin et al (2012) and Kumar et al (2014) also reported that there were increases in fruit sizes, weight, yield and water-soluble dry matter due to GA treatments. Sarita Paikra (2018) found that fruit length, fruit width, fruit weight, fruit volume, fruit diameter and yield per plant as well as yield were increased considerably in strawberry cv. Sabrina with application of RDF + Gibberellic acid 75 ppm (T3).…”

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.
