Field trial was conducted on effect of foliar nutrition with zinc and boron on the performance of black pepper (Piper nigrum L.) varieties under hill zone (Zone-9) of Karnataka from May 2016 to June 2017 at Horticulture Research and Extension Centre, Sirsi (UHS, Bagalkot), Uttara Kannada district. Present trial was laid out in split plot design replicated thrice with three black pepper varieties (IISR-Shakti, IISR-Thevam and Panniyur-1) as main plot and foliar nutrition (zinc-0.5%, boron-0.15%, combination of zinc 0.5% + boron 0.15%, control - no spray) as sub plot. Among growth parameters, canopy compactness (56.67 laterals/m2), leaf area (585.50 cm2), leaf area index (2.62) were higher in the variety Panniyur-1 receiving foliar nutrition with zinc (0.5 %). Among yield attributes, number of spikes per vine (627.00) and dry weight of berries (2.61 kg/vine) were higher in the variety Panniyur-1 receiving foliar nutrition with zinc (0.5 %).
