Abstract
A scientific Research has been conducted using a RCBD technique with three replications, are focusing on two factors affecting onion growth. The purpose was to assess the impact of different sulfur levels S1 = 5, S2=15, S3=25, and S4=35 kgha-1 and potassium levels K1=100, K2=120, K3=140, and K4=160 kg /ha on the nutrient content of N, P, K, and S in onion bulbs was done in Sher-e-Bangla Agricultural University in Dhaka, Bangladesh. The time duration is October 2020 to June 2021. Based on the observations, it has been found that the bulb showed the highest level of nitrogen when treated with sulfur (5 kg/ha) and potassium (100 kg/ha respectively). In contrast, the lowest nitrogen level has been observed when the bulb was treated with sulfur and potassium (35 &140 kg/ha respectively). Furthermore, the bulb exhibited the highest concentrations of phosphorus (P), potassium (K), and sulfur (S) at a potassium 140 kg/ha and a sulfur 35 kg/ha. Conversely, the lowest values for these parameters were observed when the bulb was treated with the lowest amount of sulfur and potassium.
