An experiment was conducted at a farmer’s field at Thakurgaon district during 2014 to observe the effect of Rhizobium, molybdenum, boron and lime on chickpea (var. BARI Chola-5) and to develop an application method suitable for resource-poor farmers whether Mo and Rhizobium could be added in the seed priming process. The treatments were T1: control TSP: (20 kg P ha-1), Borax: (1 kg B ha-1) and seed priming with Sodium molybdate: (1.5 g kg-1 seed) and Rhizobium inoculum: (4 g kg-1 seed), T2: control with seed priming in water, not Mo or Rhizobium, T3: control with no B application and T4: Control + 1.5 ton dolo lime ha-1 CaCO3 + MgCO3. The highest plant height (17.1 cm), number of nodules (3.67 plant-1), number of pods (43 plant-1) and seed yield (1.28 t ha-1) were observed with the treatment containing all i.e. TSP, boron, lime, sodium molybdate and Rhizobium. Seed priming with water only (along with TSP + borax) also showed better performances in producing plant height and number of plants per plant. This trial confirmed that this was as effective as soil application of Mo + Rhizobium giving significant yield response. Economic evaluation suggested that the treatment consisting lime was suitable for obtaining higher rate of return. The results further showed that liming is necessary for chickpea cultivation in the Ruhea Soil Series of Thakurgaon district.
