The research entitled “Influence of boron and zinc on the growth of chilli under the agro climatic condition of swat” was carried out at Agriculture Research Institute Mingora (ARI) in summer 2016 in Randomized Complete Block Design (RCBD) having two factors, three replications. First factor was boron levels (0, 1.0, 2.0 and 3.0 Kg ha^-1) while other was zinc levels (0, 1.5 and 3.0 Kg per hectares).  Foliar spray of boron at vary concentrations significantly influenced all parameters. Maximum days to flowering (40.50), maximum plant height (97.11 cm), number of branches plant per plant (10.01), single fruit weight (5.43 g) and fruit diameter (0.81 cm) were observed by the foliar spray of boron @ of 3 kg per hectares. While with zinc highest days to flowering (40.24), maximum plant height (98.70 cm), number of branches per plant (9.96), number of fruits per plant (113.99), single fruit weight (5.76 g), fruit diameter (0.84 cm), were recorded in the plots to which foliar spray of zinc @ of 3 kg per hectares were sprayed. It is concluded from the results that foliar application of boron and zinc should be used @ of 3 kg per hectares for better and outstanding growth and maximum chilli production of the swat agro-climatic condition.
