Abstract (2. Language): 
An experiment on the citrus orchards was carried out to evaluate the effect of Trichoderma on the availability of micronutrients (Cu, Fe, Zn, Mn) in District Buner. For this purpose, three orchards were surveyed. Samples were collected from soil and plants before the application of Trichoderma in June 2015. The soil sample was collected from the depth of 0-30cm. The samples were analysed at ARI (N) Mingora Swat. The result showed that the entire orchards were adequate in macro and micronutrients expect nitrogen and manganese. The texture of the soil was sandy loam and almost all the orchards were deficient in organic matter. And the pH ranges from slightly acidic to slightly alkaline. In each orchard 9 plants were selected. Tree T1 are control plant,.4 gram of Trichoderma in 2 litter were applied to plant T2 T5 T8.and 8gram of Trichoderma in 4 litter were applied to plant T3 T6 T9. After the interval of 7th to 14th days the result showed that the application of Trichoderma enhanced the availability of nitrogen (N) 27% and manganese 79%, respectively. Foliar application of iron chelate was also applied for the correction of iron deficiency in plants. 8gram of iron chelate was mixed in 10 litter water and applied to plants T4, T5, T6 and 12gram of iron chelate in 10 litters was applied to plant T7, T8, T 9 in each orchard.
