Effect of Plant Growth Regulators on Growth, Yield and Quality of Strawberry (Fragaria × ananassa Duch.) cv. Winter Dawn

Abstract

Strawberries are small, typically heart-shaped fruits with a bright red skin. Strawberries are not only delicious but also packed with nutrients. Strawberries are versatile and can be enjoyed in various ways. They are commonly used in desserts like pies, cakes, and ice cream. The present investigation was laid out on the experimental site of Department of Horticulture, Sam Higginbottom University of Agriculture Technology & Sciences, Naini, Prayagraj (UP), during 2022-23. This experiment was conducted to evaluate the best treatment among GA3, NAA, Brassinosteroid on strawberry variety winter dawn. The experiment was laid out in Randomized Design having 10 treatments and replicated 3 times.  The effects of these treatments were noted on number of leaves, plant height, flowering, fruiting and fruit quality and yield attributes of Strawberry. The results of experimentation confirmed the efficiency of growth regulators for better fruit growth attributes, yield and quality of strawberry variety Winter Dawn. The study revealed that at BRs @100 ppm significantly increased the size, quality of the fruits as well as yield per plant and yield per hectare. Maximum TSS was found in the treatment T9 BRs @100 ppm. significantly increased number of fruits per plant. Among various concentrations of growth regulators, the treatment BRs @100 ppm was found significantly superior over all other treatments.
