The present field investigation was conducted at Department of Vegetable Science, College of Agriculture, OUAT, Bhubaneswar, Odisha, India during rabi season of 2017-18 to study the effect of lime, boron and zinc on growth and yield of broccoli (Brassica oleracea var. italica). The experiment was conducted with seven levels of micronutrient as soil application of borax @1kg ha-1 , ZnSO4 @ 5kg ha-1 and their combinations as well as foliar spray of 0.2% borax, 0.5% ZnSO4 and their combinations along with control as sub plot and two level of lime (with and without lime) as main plot, in split plot design replicated thrice. The results revealed that combined foliar application of 0.2% borax with 0.5% ZnSO4, irrespective of lime application recorded significantly maximum plant height (46.27 cm), leaves plant-1 (24.62), stem girth (16.85 cm), plant spread (62.20 cm), leaf area (557.50 cm2), weight and diameter of central head (313.67g,17.37cm), secondary head (88.83g, 5.33cm), total head weight (402.50g) with total head yield (136.80 qha-1) in broccoli var. Palam Samridhi. Similarly, lime application, irrespective of micronutrient significantly influence both vegetative growth, viz; plant height (42.09 cm), leaves plant-1 (23.46), stem girth (16.30 cm), plant spread (58.65 cm) and leaf area (486.62 cm2) as well as yield and yield attributing parameters, viz; weight and diameter of central head (305.52g,17.18cm), secondary head (84.36g, 5.34cm) and total head weight (389.88g) with maximum total head yield (134.73 qha-1) in broccoli var. “Palam Samridhi”. Hence, it may be concluded combined application of borax @ 0.2% with ZnSO4 @ 0.5% along with lime as soil application not only increases the growth but also yield in broccoli.
