Effect of PGR and Micronutrient on Growth, Yield and Quality of Cauliflower (Brassica olereacea var. botrytis L.) Cv Pusa Deepali

A field experiment was conducted during rabi season of 2024 at the Horticulture Research Farm, Faculty of Agricultural Sciences and Allied Industries, Rama University, Kanpur (U.P.), Kanpur, to study the effect of plant growth regulators (PGRs) and micronutrients on the growth, yield and quality of cauliflower (Brassica olereacea var. botrytis L.) cv Pusa Deepali. The experiment was laid out in a Randomized Block Design (RBD) with nine treatments, each replicated thrice. The treatments include T1 (control), T2 GA3 @ 60 PPM, T3 GA3 @100 PPM, T4 NAA @100 PPM, T5 NAA @150 PPM, T6 Boron @ 2%, T7 GA3 @ 60 PPM + Boron 2%, T8 GA3 @ 100 PPM + Boron @ 2% and T9 NAA @ 100 PPM + Boron @ 2% and T1 Control No PGR and no micronutrient (Control) are used. The results showed that the treatment involving use of T8 GA3 @ 100 PPM + Boron @ 2% was recorded highest plant growth, yield and quality of cauliflower as compared to other treatments.
