鹰嘴豆（cv.在2001-2002和2002-2003年的拉比季节期间，在杰索尔的AEZ 11下的石灰性深灰色洪泛区土壤和Rahmatpur的AEZ 13下的非石灰性灰色洪泛区土壤中进行了巴里Chola-5）。目的是找出硼和钼的最佳剂量，以获得最大产量。本试验采用沿着施硼（0、1、2、2.5 kg/ha）、钼（0、1、1.5、2 kg/ha）4个水平，并配施N_（20）、P_（25）、K_（35）、S_（20）、Zn_（20）2 kg/ha和牛粪5 t/ha。在杰索尔和拉赫马特普尔的研究年份中，B2.5 Mo 1.5 kg/ha和B2.5 Mo 1 kg/ha的组合分别产生了显着更高的产量。所述处理产生了最高的平均产量，分别为杰索尔和Rahmatpur的2.10和1.49吨/公顷，比对照（B 0 M0）高出约53%。硼钼配施比单施有上级效果，但硼钼的增产作用主要是硼钼配施。然而，根据回归分析，计算出最佳处理组合为B2.34 Mo1.44 kg/ha（杰索尔）和B2.20 Mo1.29 kg/ha（Rahmatpur）。
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 B2.5 Mo1.5 kg/ha and B2.5 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 B2.34 Mo1.44 kg/ha for Jessore and B2.20 Mo1.29 kg/ha for Rahmatpur.
