摘要：The study was conducted at the College of Agriculture and Research Station, Indira Gandhi Krishi Vishwavidylaya, Janjgir- Champa (Chhattisgarh), during the year 2017-18 Rabi Season to Study the Influence of Rhizobium and phosphate solubilizing bacteria on the performance of field-grown Lathyrus (Lathyrus sativus L) under climatic conditions of Chhattisgarh plains. In the present investigation total of 8 treatments T1 -Control (No inoculum no fertilizer), T2- Recommended Dose of Fertilizer RDF(N:P: K::20:40:20), T3- Rhi.HG-25 (Std.) + PSB-H-27 (Std.), T4 Rhi.HG-25 + Korba PSB-118, T5 - Rhi.L-3 Lathyrus + PSB-H-27, T6 Rhi.L-3 Lathyrus + Korba PSB-118, T7- Rhi.L-11 Lathyrus + PSB-H-27 , T8 Rhi.L-11 Lathyrus + Korba PSB-118. Recommended Dose of Fertilizer (RDF) T2 recorded maximum and significantly higher value of plant height over rest of the treatments at 45, 60 DAS and at maturity except T7 (Rhi.L-11 Lathyrus + PSB-H-27) treatment which was statistically similar at maturity. A general perusal of the data of the fresh plant reveals that T2 (Recommended Dose of Fertilizer, RDF) recorded the maximum and significantly higher value of fresh weight over the rest of the treatments at a later stage of crop growth i.e 60 DAS and at harvest. A critical perusal of the nodule count data revealed that treatment T8 (Rhi.L-11Lathyrus+ KorbaPSB-118) was found superior over all the treatments showing the superiority of combined use of local strains over other strains and RDF. In case of grain yield the maximum grain yield were observed in 1451.39 kg/ha due to application of T8 (Rhi.L-11Lathyrus+ KorbaPSB-118) followed by T2 RDF 1415.28 kg/ha, T4 (Rhi.HG-25 +KorbaPSB-118)1388.89 kg/ha, T7 (Rhi.L-11 Lathyrus+ PSB-H-27)1344.44 kg/ha, T6 (Rhi.L-3 Lathyrus + PSB-H-27)706.94 kg/ha, 12.77 kg/ha, T5 (Rhi.L-3 Lathyrus+ PSB-H-27) 1216.67 kg/ha, T3 (Rhi.HG-25 + PSB-H-27) 1219.94kg/ha. Maximum grain yield was observed due to the application of effective local strains of rhizobia and PSB which also enhanced the nodulation activity due to an increase in the available soil phosphorus. The maximum and significantly higher value of grain yield straw yield (1118.06 kg/ha) was observed due to treatment T8 (Rhi.L-11 Lathyrus+ Korba-PSB-118) which was statistically superior over all the treatments except T2 RDF.
