Effect of micronutrients and PGRs on growth and yield of Tomato (Solanum lycopersicum L.) cv. Azad-T6

Abstract

The present investigation entitled “Effect of micronutrients and PGRs on growth and yield of tomato (Solanum lycopersicum L.) cv. Azad-T6” was carried out during autumn season of 2022 at Experimental Unit, Department of Horticulture, Tilak Dhari Post Graduate
College, Jaunpur (U.P.) India. Experiment was planned with eleven treatments, three replications and was laid out in randomized block design. The treatments were T1 (control), T2 (GA3 50ppm), T3 (GA3 100 ppm), T4 (NAA 50 ppm), T5 (NAA 100 ppm), T6 (ZnSO4 0.5%), T7 (ZnSO4 1%), T8 (Boric acid 50 ppm), T9 (Boric acid 100 ppm), T10 (FeSO4 100 ppm) and T11 (FeSO4 150 ppm). The tomato crop's vegetative growth, flowering, and yield were found greatly enhanced by the application of micronutrients (ZnSO₄ , Boric acid, FeSO₄ ) and plant growth regulators (GA₃ , NAA) at two distinct concentrations. Better quality and productivity resulted from these treatments improved the plant's overall performance. The most successful treatment for improving vegetative development, blooming, and yield metrics was T3 GA₃ (100 ppm).
