Fertilizing chickpea for high yield with special emphasis on boron and molybdenum in grey floodplain soils of bangladesh

Abstract

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
