Effects of Boron and Molybdenum on the Yield of Chickpea

Abstract

Field experiments on chickpea (cv. BARI Chola-5) were carried out in Calcareous Dark Grey Floodplain Soil under AEZ 11 at Jessore and Non Calcareous Grey Floodplain Soil under AEZ 13 at Rahmatpur during the rabi season of 2001-2002 and 2002-2003. The objective was to find out the optimum dose of boron and molybdenum for yield maximization. Four levels each of boron (0, 1, 2 and 2.5 kg/ha) and molybdenum (0, 1, 1.5 and 2 kg/ha) along with a blanket dose of N₂₀ P₂₅ K₃₅ S₂₀ Zn₂ kg/ha & cowdung 5 t/ha were applied in this study. The combination of B_2.5 Mo_1.5 kg/ha and B_2.5 Mo₁ kg/ha produced significantly higher yield in both the years of study at Jessore and Rahmatpur, respectively. The said treatments produced the highest mean yields of 2.10 and 1.49 t/ha for Jessore and Rahmatpur, respectively, which was around 53% higher over control (B₀ M₀). The combined application of both boron and molybdenum were found superior to their single application even though boron played major role in augmenting the yield. However, from the regression analysis, the optimum treatment combination was calculated as B_2.34 Mo_1.44 kg/ha for Jessore and B_2.20 Mo_1.29 kg/ha for Rahmatpur.

Key words: Boron, molybdenum, chickpea, yield, flood plain soil.
