The research experiment titled as “The effect of iron and zinc on the growth and yield of chili (Capsicum annuum L.)” was conducted at Horticulture Research Farm, The University of Agriculture Peshawar, in summer of year 2022. There were four levels of Iron (0, 0.25, 0.5 and 0.75 %) and four levels of Zinc (0, 0.25, 0.5 and 0.75 %). The statistical design i-e Randomized Complete Block Design, with three replications and experimental units, was used. The application of Iron and Zinc on chili (Cv. P6) seedlings showed there was a significant effect on almost all the studied parameters. With respect to application of iron, the maximum branches plant-1, leaf chlorophyll content, fruit length, number of fruit plant-1, single fruit weight, root length, ascorbic acid and yield tons ha-1 were recorded for treatment of Iron application at the rate of 0.75 %, while maximum plant height was recorded when Iron was applied at the rate of 0.5 %. The results showed that in case of Zinc it significantly affected all parameters. The maximum plant height, branches number per plant, leaf chlorophyll content, number of fruits plant-1, length of fruit, single fruit weight, ascorbic acid content, length of root, and yield tons ha-1 were recorded for treatment of Zinc at 0.75 %. Maximum days to flowering and days to fruit set was recorded in untreated plants. The treatments of Iron 0.75 % and Zinc 0.75 % were found more effective for better growth and yield of chilies and are recommended for grower in Peshawar valley.
