Abstract: The study was carried out on three years old guava plants during the year 2017-18 at RHR&TS, Dhaulakuan, Sirmour (H.P.), India. The experiment was laid out in a Randomized Block Design (RBD) with three replications comprising of sixteen treatment combinations Among different treatments, significantly maximum increase in annual shoot growth, plant height, spread, stem girth, flowering, fruit set, yield and reduction in fruit drop were recorded in T₁₅ (zinc sulphate @ 0.5% + borax @ 0.2% + manganese sulphate @ 0.5% + iron sulphate @ 0.4%). Leaf nutrient contents were also significantly affected by foliar application of combined micronutrients. Therefore, it is concluded that combined foliar application of zinc sulphate @ 0.5% + borax @ 0.2% + manganese sulphate @ 0.5% + iron sulphate @ 0.4% proved to be the most effective treatment.
