Abstract:
The productivity of groundnut is important for the farmers to get a higher yield in different season. Growing of groundnut in summer, increase the productivity through the different management practices. A field experiment was conducted at Dryland Agricultural Research Station, Chettinad, Karaikudi, Sivagangai Disctrcit, Tamil Nadu during summer, 2022 to study on the influence of seed bed preparation and microbial consortium on the growth and yied of groundnut. The experiment was laid out in factorial randomized block design replicated thrice. The treatments consisted of three land configuration methods viz., L₁- Flat bed, L₂- Ridges and furrow, L₃- Raised bed and five microbial consortium levels viz., M₁- RDF (25:50:75 kg NPK ha^-1), M₂- RDF + Seed treatment with Rhizobium, M₃- RDF + Seed treatment of Rhizobium + soil application of AMF, M₄- RDF + Seed treatment of Rhizobium + soil application of AMF + foliar spraying of PPFM + seed treatment with Bacillus altitudinis (FD 48) and M₅- RDF + Seed treatment with Rhizobium + soil application of AMF + foliar spraying of PPFM and Bacillus altitudinis (FD 48). Among the land configuration, ridges and furrow registered the higher plant height, LAI, DMP and yield attributes. In microbial consortium application of RDF + seed treatment of Rhizobium + soil application of AMF + foliar spraying of PPFM and Bacillus altitudinis (FD 48) recorded the maximum plant height, LAI, DMP and yield attributes. Sowing of groundnut in ridges and furrow and application of microbial consortium; seed treatment of rhizobium + soil application of AMF + foliar spraying of PPFM and Bacillus altitudinis (FD 48) has enhanced the growth and yield attributes.
