Response of PGRs and micronutrients on physico-chemical attributes of tomato (Solanum lycopersicum L.) cv. Azad T6

Abstract

The study entitled “Response of PGRs and micronutrients on physico-chemical attributes of Tomato (Solanum lycopersicum L.)” cv. Azad T6 was conducted during autumn season of 2022 at the Department of Horticulture, Tilak Dhari Post Graduate College, Jaunpur, India. The study was aimed to evaluate the impact of different micronutrients (ZnSO₄, Boric acid, FeSO₄) and plant growth regulators (GA₃, NAA) at two doses each on the Azad-T6 tomato variety using a randomized block design with eleven treatments and three replications. Treatments were T1 (control), T2 (50 ppm of GA₃), T3 (100 ppm of GA₃), T4 (50 ppm of NAA), T5 (100 ppm of NAA), T6 (0.5%), T7 (1%), T8 (50 ppm of boric acid), T9 (100 ppm of boric acid), T10 (100 ppm of FeSO₄), and T11 (150 ppm of FeSO₄). The findings indicated that Azad-T6 tomato production, quality, and vegetative growth were all markedly enhanced by these treatments. T3 (GA₃ at 100 ppm) was the most successful treatment, significantly increasing plant output, quality attributes, and growth and most effective in improving plant productivity and attributes.
