The treatment T₉ (RDF + Borax 2 kg soil application +0.2% B through borax as foliar application) recorded maximum plant height (33.33 and43.93 cm), number of leaves per plant (8.63 and 15.06), leaf length (16.73 and 32.16 cm) and leaf width (10.56 and 17.20 cm) at 30 DAT and at harvest. This treatment also showed higher leaf area at knob initiation (368.73 cm²), leaf area at knob harvest (655.5 cm²), earliest days to 50% knob initiation (23.03),diameter of knob (8.74 cm), volume of knob (323.83 cc), average weight of knob (183.7 g) and knob yield ha^-1 (98.43) compared to other treatments. Overall precise boron application was proved to be beneficial for vegetative growth, physical characters and yield of knob in knolkhol.
