Abstract: Boron (B) and molybdenum (Mo) are important essential micronutrients required for normal plant growth and development and deficiencies are very common in Cole crops. To combat this and to produce quality broccoli cv. Pusa KTS 1 with more yield the present investigation was conducted during rabi season of 2015-16 at Horticulture Research Farm of Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow, Uttar Pradesh, India. There were ten treatments comprising recommended dose of fertilizers (RDF), Borax at two levels (1.5 and 2.5%), Ammonium molybdate at two levels (1.5 and 2.5%) and control without any fertilizer application and laid out at randomized block design with three replications. The observations and statistical analysis clearly revealed that the vegetative growth (plant height, stem circumference, plant spreading, number of leaves, length and width of leaves etc), curd weight, yield, and curd physico-chemical qualities were improved with application of boron and molybdenum in addition with RDF. However, combined application of boron and molybdenum were more effective than their sole application. Among the several applications, treatment T7 [RDF + Borax (1.5%) + Ammonium molybdate (2.5%)] was found as the best combination for good growth, better yield and superior quality curd production of broccoli cv. Pusa KTS 1 under Lucknow condition.
