The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur with the objectives to develop suitable and economic fertilizer dose for sweet orange cultivation through integrated nutrient management (INM) and to quantify the change of soil health due to addition of organic manure during 2016-2020.There were seven treatments viz. T1: 100% RDCF, T2: Cowdung 5 tha-1 + IPNS based inorganic fertilizer, T3: Cowdung 10 tha-1 + IPNS based inorganic fertilizer, T4: Poultry manure 3 tha-1+IPNS based inorganic fertilizer, T5: Poultry manure 5 tha-1 + IPNS based inorganic fertilizer, T6: 125% RDCF and T7: control. The tested variety was BARI Malta-1. The experiment was laid out in Randomized Complete Block design (RCBD) with 7 replications. Results revealed that, T4 treatment (Poultry manure 3 tha-1 + IPNS based inorganic fertilizer produced highest average sweet orange yield (7.23 t ha-1) and the lowest yield (1.85 t ha-1)recorded in the T7 comprises with control treatment. Soil organic carbon (SOC), total N, available P, K and S contents in post-harvest soil were also highest in T4 treatment. The overall results indicate that T4 treatment can help increase fruit yield of sweet orange and carbon accumulation in soil which in turns enriching soil organic matter.
