Abstract
This experiment was conducted in a mango garden at Bandarban, Khagrachari and Rangamati district in hilly area of Bangladesh from 15 October 2015 to 30 May 2017 to study the effects of integrated nutrient management on the performance of mango in hills. The experiment was laid out in a randomized block design with three replications. There were four treatments Mango (5-10 yrs. old). The treatments are: 4 (four) Fertilizer packages * T1= Control, T2= N230P53K100 S 36Zn3 B4 + CD/Compost 20000 g/plant, T3= 125% of T2 and T4= 150% of T2. In Khagrachari site, Mango yield varied from 7.72-22.30 kg/plant. The highest mango yield 22.30 kg/plant wasin T4 treatment (150% of T2). In Bandarban site, Mango yield ranged between24.13-48.25 kg/plant. The highest mango yield 48.25 kg/plant found in T3 treatment (125% of T2). In Rangamati site, Mango yield varied from 9.62-23.10 kg/plant. The highest mango yield 23.10 kg/plant found in T4 treatment (150% of T2). In most cases the significant difference in yields were found in T4 treatments in three districts.
