The experiment was conducted in the farmers field of shibpur, puthia, Rajshahi during three consecutive years at rabi season of 2017-18, 2018-19 and 2019-20 to evaluate the effect of fertilizers on puddling garlic cultivation and to find out a suitable combination of different fertilizers for puddling garlic production. The experiment was laid out in RCBD design with six dispersed replications and four fertilizer doses viz. T1=STB fertilizer dose for high yield goal, T2=20% higher NPK than STB, T3=40% higher NPK than STB supplemented with 5 ton ha-1 cowdung and T4=Farmers dose. Three tones ha-1 of rice straw was used as mulch with all the fertilize doses. Garlic variety BARI Rasun 2 was used as test crop. Among the treatments, the highest average yield was obtained from T3= 40 % higher NPK than STB (9.57 t ha-1) which was similar to T4= Farmers practice (9.52 t ha-1). Nutrient addition was very much unbalanced in T4. Maximum gross return (574200 Tk ha-1), net return (328465Tk ha-1) and BCR (2.34) were found in T3 treatment. The treatment T3 produced the lowest break-even price (25.68 Tk kg-1) and the highest sustainability index (85.5%). Considering all these facts, the treatment T3(40% higher NPK than STB =220-18-84-34-2.5-3 kg ha-1 NPKSZnB respectively) should be recommended for wide extension of puddling garlic cultivation in High Ganges River Floodplain Agro-ecological zone (AEZ-11) in Bangladesh.
