Effect of Plant Growth Regulators on Cherry Tomato (Solanum lycopersicum var. cerasiforme)

A cherry tomato is a small-sized tomato variety known for its round shape and sweet flavor. Therefore, at the Department of Horticulture at Naini Agricultural Institute, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh, an investigation titled "Effect of Plant Growth Regulators on Cherry Tomato" was conducted during the Rabi-2022-23 season to assess the impact of plant growth regulators on the growth, quality, and yield of Pusa Cherry 1 tomatoes, as well as analyze the economic aspects of different treatments. Ten treatments were employed, including control with different concentrations of growth regulators (GA3 and Auxin) and Kinetin. The study found that using plant growth regulators had a significantly positive effect on cherry tomatoes for all traits. Among the treatments tested, T3(GA3 @ 75 ppm) showed the most favourable results in terms of plant height, number of primary branches, early flowering and maturing. T3 also demonstrated superior performance in terms of fruit weight, the maximum number of fruits per plant, and yield per plant.
