A field experiment was conducted during 2018-19 to study the “Effect of application of Ammonium molybdate on enzymatic activity and nodulation in pigeon pea grown on Vertisol” at experimental farm, Department of Soil Science and Agricultural Chemistry, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani. The experiment was laid out on Vertisol with five treatment combination replicated four times in randomized block design. The treatment consists of T1- Absolute control, T2- Only RDF (25:50 kg N and P2O5 ha-1), T3- RDF+ Ammonium molybdate through seed treatment @1 g kg-1 seed, T4- RDF+ Ammonium molybdate through soil application @ 2 kg ha-1, T5 - RDF+ Ammonium molybdate through foliar application @ 0.5 %. The results found that the abundant soil enzymatic activity observed in treatment receiving foliar application of Ammonium molybdate along with recommended dose of fertilizer as compare to rest of the treatments. Enzymatic activity of various soil enzymes i.e. dehydrogenase, acid and alkaline phosphatase increased from flowering to pod filling and then decreased at harvesting due to low moisture content in soil. In nodulation number of nodules and nodules weight was increased due to application of RDF+ ammonium molybdate through foliar application followed by the treatment receiving ammonium molybdate + RDF through soil application.
