Ammonium Molybdate: A Potential Bioregulator for Improving Curd Yield and Quality in Broccoli

To study the influence of foliar feeding of Boric acid, Ammonium molybdate, Gibberelic acid, Zinc sulphate and Triacontanol on curd yield and quality of broccoli (Brassica oleracea Var. Italica) under naturally ventilated polyhouse conditions during rabi season of 2020-21 at College of Horticulture, Venkataramannagudem. The experiment consists of 15 treatments laid out in Randomized Block Design (RBD) with three replications. Ammonium molybdate @0.40% significantly increased the curd weight, diameter, length and total yield per plot. Foliar application of GA3@75ppm+ Boric acid @ 0.40% + Ammonium molybdate @ 0.40% increase the ascorbic acid content. High to moderately compact curds observed in the treatments T1 (Boric acid @ 0.25%), T6 (Ammonium molybdate @ 0.50%) and T8 (Boric acid @ 0.50% + Ammonium molybdate @0.50%).
