Soil test values gave preliminary indication about the shortage of N, P, K, S and B on the Grey Floodplain Soils of Bogra. Subsequent missing element trial conducted with chickpea during 1992-93 growing season revealed that omission of B and Mo in addition to N, P, K and S from the complete fertilization package (NJQ P^Q, K4Q, SJQ, Z115, Bj Moj kg/ha) seriously reduced the yield. In absence of B from the package, yield reduction as high as 93% was encountered. When additional 1kg B/ha was used with the package, 37% higher yield was recorded. In the succeeding growing season (1993-94), yield response of chickpea to applied B and Mo was studied. Results reflected that the crop responded dramatically to applied B. Application of Mo in presence of B also improved the yield appreciably. The judicious application rates of these two nutrients for optimum chickpea yield were found to be B2 Moj kg/ha. This treatment resulted in a yield increase as high as 514% over B2 MOQ
