Abstract: Field experiment was conducted at department of Vegetable Science, OUAT, BBSR during Rabi 2018-2019, to study the effect of lime, micronutrients (B and Zn) and spraying schedule on growth and yield of broccoli variety “PalamSamridhi”. The field experiment was conducted by adopting split – split plot design replicated thrice. 12 treatments consist of lime in main plot ( 0.2 LR and 0.3 LR), micronutrients as subplot (viz; 3 levels: foliar application of boron @ 0.2 %, ZnSO4 @ 0.5 % and their combinations i.e. borax @ 0.2 % + ZnSO4 @ 0.5 %) and 2 levels of spraying schedule as sub-sub plot (once and twice).The results indicated that application of lime @ 0.2 LR significantly increased not only the vegetative growth (plant height- 58.07 cm)but also yield (143.98 q ha-1) and yield attributing traits (secondary head weight - 135.06 g) as compared to application of lime 0.3LR irrespective of micronutrient and spraying schedule. Among micronutrients results indicated that combined application of borax @ 0.2 % + ZnSO4 @ 0.5 % significantly increased vegetative growth (plant height-61.71 cm, plant girth- 10.22 cm, leaf area- 440.35 cm2); head yield attributing parameters (viz. weight of central head- 266.03 g ; secondary head weight- 150.29 g and total head weight- 416.32 g) with head yield (145.76 q ha-1), compared to sole application irrespective of lime application and spraying schedule. Results also showed that invariably spraying of micronutrients once recorded better vegetative growth and yield attributing characters than spraying thrice, irrespective of lime application and spraying schedule.Thus it may be concluded that soil application of lime @ 0.2 LR, along with combined single spray application of ZnSo4 and borax not only increases vegetative growth and yield attributing parameters but also yield in Broccoli variety “ PalamSamridhi”.
