At the Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh, a two year field study was conducted to examine the impact of integrated potash management on improving mustard yield and potassium uptake. There were six different treatments including STB dosage and potassium enriched organic amendments (rice husk ash and rice straw compost) at various rates. BARI Sarisha-14 was utilized as the test crop and the experiment was set up using a randomized complete block design (RCBD) with three replications and six treatments including T1 (Control), T2 (STB fertilizer dose), T3 (STB + rice husk ash @ 1 t ha-1), T4 (STB + rice husk ash @ 2 t ha-1), T5 (STB + rice straw compost @ 3 t ha-1) and T6 (STB + rice straw compost @ 5 t ha-1). The results showed that, treatment receiving STB fertilizer dose with rice husk ash @ 2 t ha-1, had the highest average seed yield of mustard (1.43 t ha-1) whereas control treatment produced the lowest yield (0.53 t ha-1).The treatment (STB + rice husk ash @ 2 t ha-1) had the largest gross margin (Tk 112490 ha-1) and BCR, according to cost and return analysis. Additionally, integrated potash management techniques enhanced potassium uptake in comparison to control or sole STB fertilizer dose. The overall findings showed that the treatment package consisting of STB with rice husk ash @ 2 t ha-1 is superior to other packages.
