Studies on the effect of growth regulator and vermicompost on growth and yield of different cultivars of strawberry (Fragaria x ananassa Duch)

Abstract

:The present investigation was carried out at the Horticulture Research Center, of the SardarVallabhbhai Patel University of Agriculture and Technology, Meerut during 2013-2014.The maximum number of fruits (20.85) were recorded in the variety Chandler which was significantly superior to the rest of the varieties and followed by Gorella,Selva and Confictura.The maximum fruit yield per plant (385.57g) was recorded in the variety Chandler which was superior to the rest of the varieties and was followed by Selva, Confictura and Douglas. The minimum fruit yield per plant (177.79g) was noted in Gorella variety.The maximum fruit weight (18.41g) was recorded in the variety Chandler which was significantly superior to the rest and followed by Confictura, Selva and Douglas.Application of gibberellic acid (GA 3 ) 100 ppm + vermicompost @ 100q/ha was found to be the best treatment in response to fruit weight among different varieties of strawberry and recorded 16.48g. The maximum fruit yield (171.36q/ha) was recorded in the variety Chandler which was significantly superior to the rest and was followed by Selva, Confictura and Douglas; however, Selva and Confictura were statistically at par to each other. Variety Chandler responded maximum effect on fruit yield per hectare i.e. 205.357q/ha with the spray of gibberellic acid (GA 3 ) 100 ppm and application of vermicompost @ 100q/ha. The maximum total soluble soilds (10.68ºBrix) was recorded in the variety Douglas which was superior to the rest and was followed by Confictura, Selva and Gorella. The minimum TSS value (9.41ºBrix) was noted in Chandler variety. Douglas responded maximum effect on TSS value i.e. 11.50 ºBrix with the spray of gibberellic acid (GA 3 ) 100 ppm and application of vermicompost @ 100q/ha as basal dose which was statistically significant to other treatments and followed by Confictura, Selva and Gorella. Viewing the above observations, Chandler, Confictura and selva were found promising for commercial cultivation, however, Gorella was found to be earliest among all.KEY WORDS : Growth regulator, Vermicompost, Growth, Yield, Cultivars HOW TO CITE THIS ARTICLE : Rajbhar, Yogesh Prasad, Singh, Bhagat, Singh, Gopal, Singh, D.K. and Kumar, Mukesh (2015).

Improving Runner Production, Total yield and Postharvest Quality of Strawberry Fruits using Plant Growth Regulators

“…Total soluble solids Total soluble solids readings showed that the maximum amount was noted in strawberry fruits sprayed with T 2 (GA 3 @ 100 ppm) (13.21%), while the minimum amount was observed in T 7 [Control (Only water)] (7.56%) (Table 2). Effect of growth regulators on sugars of strawberry is highly dependent on concentration and chemical composition of plant growth regulators (Jamal Uddin et al, 2012;Rajbhar et al, 2015). In present study, GA 3 @ 100 ppm has been reported to be the most effective among treatments in terms of total soluble solids of strawberry which might be due to its right concentration which helped in increasing the total soluble solids of strawberry.…”

Plant Growth Regulators and Strawberry Production

“…Dual inoculation with 75% N and 100ppm BA gives maximum Yield and fruit set was maximum in combination of GA3 100ppm + 50% N + azotobactor + azospirillium application. Rajbhar et al, (2015) found that GA3 100ppm + vermicompost @100q/ha resulted more TSS (10.68 ºBrix) in strawberry var. Douglas.…”

“…Sujata. Rajbhar et al, (2015) reported that GA3 (100 ppm) resulted higher yield in Chandler cv. of strawberry.…”

“…Higher number of flowers per plant (24.1) and number of fruit per plant (22.5) was obtained from NAA (100ppm) over the other treatments. Rajbhar et al, (2015) reported that application of GA3 100ppm + vermicompost @100q/ha resulted higher yield in strawberry cv. Chandler.…”

Empirical Studies of Strawberry Growth, Flowering and Fruiting Behavior Using Integrated Nutrient Management

“…Hassan (2015) and Saha et al (2019) were reported the better vegetative growth of plants and number of leaves in strawberry with the use organic and in-organic fertilizers. Rajbhar et al, 2015 was also reported same while working on strawberry.…”
