ThesisItem Open Access Effect of Rhizobium, Phosphobacteria and P-Levels on Growth, Yield and Acquisition of Nutrients by Urdbean (Vigna mungo L.)(Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut- 250 110, (U.P.) INDIA, 2012) Surya Kant; Satendra Kumar; Ashok Kumar, B.P. Dhyani,S.P. Singh,Adesh SinghAn experiment was conducted at Crop Research Centre (CRC), Chirori of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during kharif-2011. Thirteen different treatments were replicated thrice in a randomized block design. The soil of experimental site was sandy loam in texture, low in organic carbon and medium in available phosphorus with alkaline in reaction. Treatments comprises T1: control, T2: Phosphate Solubilizing Bacteria (PSB), T3: Rhizobium, T4: PSB + Rhizobium, T5: 25 kg ha-1 P2O5 + PSB, T6: 25 kg ha-1 P2O5 + Rhizobium, T7: 25 kg ha-1 P2O5 + PSB + Rhizobium, T8 : 50 kg ha-1 P2O5 + PSB, T9: 50 kg ha-1 P2O5 + Rhizobium, T10: 50 kg ha-1 P2O5 + PSB + Rhizobium, T11: 75 kg ha-1 P2O5 + PSB, T12: 75 kg ha-1 P2O5 + Rhizobium and T13: 75 kg ha-1 P2O5 + PSB + Rhizobium. Significantly higher grain yield, effective nodules and N & P contents in plant sample were obtained with the application of 75 kg ha-1 P2O5 + PSB + Rhizobium (T13) as compared to all other treatments T12 and T10. The highest grain (9.28qha-1) and straw (31.60qha-1) yield were obtain under T13, where as the control treatments registered the 6.31 and 21.48 qha-1 grain and straw yield respectively. The treatments also registered the highest N & P contents in soil after harvest of the crop followed by T12. From the above study it also seems that application of 50 kg ha-1 P2O5 with PSB and Rhizobium (T10) also improved the grain yield and NP content in soil after harvest in comparison to control
