Cauliflower (Brassica oleracea var. botrytis L.) is one of the most imperative vegetables cole crops grown in India. The edible part, i.e., curd is a ‘prefloral fleshy apical meristem’ and it is generally white in colour and may be enclosed by internal leaves before its exposure. It grows in all kinds of soil with good soil fertility and fine drainage system; because of over pulling out of the plant food elements by the crop, most of the micronutrient becomes in short supply to the crops and some disorders appear resulting in low yield and quality. Therefore, the present investigation was carried out by Krishi Vigyan Kendra, Fatehpur Shekhawati, 332301, Sikar-I, Sri Karan Narendra Agriculture University, Jobner, 303329 during rabi, 2021-22 at 10 farmers field to study the effect of foliar application of boron and molybdenum on growth, yield and economics of cauliflower. The experiment was laid out with ten replications having two treatments viz., T1- Farmers’ practice (without micronutrients) and T2- foliar spray of borax @ 0.3% + ammonium molybdate @ 0.05% at 45 days after transplanting. The maximum plant height (31.94 cm), number of leaves/plant (12.31), diameter of curd (17.29 cm), weight of curd (970.00 g), and yield 357.89 q/ha were found with the application of foliar spray of borax @ 0.3% + ammonium molybdate @ 0.05% at 45 DAT as compared to farmers practices (control). Similarly, highest gross return (Rs.357890/ha), net return (Rs.280740/ha) and benefit cost ratio (4.64) were also recorded in T2 whereas, it was lowest in farmers practices
