Four treatments were set up for each crop. For chickpea and mungbean, the treatments were T<sub>1</sub>=Recommended fertilizer dose as per FRG, 2005 BARC (N<sub>15</sub>P<sub>18</sub>K<sub>10</sub>S<sub>&lt;5</sub>Z<sub>n0.5</sub>B<sub>0.5</sub>); T<sub>2</sub>=Soil test based fertilizer dose   (N<sub>21</sub>P<sub>23</sub>K<sub>30</sub>S<sub>18</sub>Z<sub>n2</sub>B<sub>1.5</sub>); T<sub>3</sub>=Farmers’ practice (N<sub>23</sub>P<sub>15</sub>K<sub>8</sub>); and T<sub>4</sub>=Control (without fertilizer). For T.Aman, the treatments were T<sub>1</sub>= Recommended fertilizer dose as per FRG, BARC (N<sub>66</sub>P<sub>7</sub>K<sub>12</sub>S<sub>6</sub>Z<sub>n1</sub>); T<sub>2</sub>=Soil test based fertilizer dose (N<sub>130</sub>P<sub>14</sub>K<sub>76</sub>S<sub>6</sub>Z<sub>n1.5</sub>B<sub>1.0</sub>); T<sub>3</sub>=Farmer practice (N<sub>90</sub>P<sub>10</sub>K<sub>15</sub>); and T<sub>4</sub>=control.   Experimental results revealed that among the treatments the highest seed and stover/straw yields of chickpea (1524 kg/ha and 4049 kg/ha), mungbean (2208 kg/ha and 5121 kg/ha) and T.Aman (5414 kg/ha and 5615 kg/ha) were recorded in treatment T<sub>&lt;2</sub>. This treatment was significant at 5% level except seed yield of   chickpea in 2008-09. T<sub>3</sub> treatment showed significant difference with T<sub>4</sub> treatment.  The lowest seed and stover/straw yields of all the crops were recorded in control treatment (T<sub>4</sub>). After completion of two years’ pattern cycle, the organic matter, total  nitrogen, phosphorus, sulphur, zinc, and boron were higher in treatment T<sub>2</sub>. The   economic analysis revealed that the highest BCR (2.57) was recorded in T<sub>2</sub>, while the lowest value (2.14) was noted in T<sub>4</sub>. Therefore, the soil test based   fertilizer dose may be considered as suitable dose for this cropping pattern that ensure higher yield and increase soil fertility.</p> <p>DOI: <a href="http://dx.doi.org/10.3329/bjar.v37i2.11226">http://dx.doi.org/10.3329/bjar.v37i2.11226</a></p> <p>Bangladesh J.
