Chalanbeel is a low land area of northern part of Bangladesh where garlic is considered a cash crop by farmers. Farmers practices zero or minimum tillage for garlic production. The appropriate fertilizer dose has not yet been determined for garlic in order to increase production. During the 2016 Rabi season, the experiment was carried out at the Chalanbeel area, Natore (AEZ-5) to determine the best fertilizer combinations for producing B.Aman and garlic with the least amount of tillage. Eight treatments total, with three replications, were outlined in RCBD. In 2016-17 the treatments T₂ produced the highest garlic (9.03 t/ha). There are differences in the yield metrics between the treatments in the case of B.Aman. Treatment T₂ had the highest B.Aman yield (3.40 t ha^-1) and it was statistically identical to all other treatments except T₈. In the subsequent year (2017-18), the highest garlic yield (8.17 t ha^-1) was produced from treatment T₆ (T₁+ 25% NPK). The most B.Aman production (3.27 t ha^-1) was found in treatment T₄ (T₁ + NP 25%) and in treatments T₈ produced lowest yield across the year and crops. According to soil test results and economic viability for the garlic-B.Aman rice cropping pattern in Bangladesh's Chalanbeel areas (AEZ-5 soil), the proper fertilizer doses for the garlic B.Aman rice in those places are N₁₂₅P₄₃K₁₂₅S₃₂Zn₂B₁ and B. Aman N₃₂P₁₀K₁₃S₈Zn₁ and restoring optimum growth and moisture retention is aided by the zero tillage.
