Abstract: A field experiment was conducted to evaluate the performance of maize upon applicaton of different biostimulants namely, humic caid extracted from FYM, Spirulina algal extract and microbial consortia in red soils of zone 6 of Karnataka during Kharif 2018 on sandy loam soil at college of Agriculture, V.C. Farm, Mandya. The experiment was laid out in RCBD with thirteen treatments including control, 100% RDF, 100% RDF + microbial consortia (MC), 100% RDF + MC + humic acid @ 0.25 and 0.50%, 100% RPP + MC + algal extract @ 10 and 20% and the above treatments were repeated with 75% RPP. Results revealed that application of biostimulants had a significant effect on growth and yield of maize. Application of 100% RPP along with biostimulants had significant effect on yield parameters, root parameters and yield of maize. Higher root length, shoot length, root: shoot, yield parameters like cob length, number of rows per cob, number of kernels per row and test weight was higher in T7 treatment receiving 100% RPP along with microbial consortia and 20% algal extract. Treatment T7 recorded significantly higher grain and stover yield of 81.67 and 89.79 q ha-1, respectively.
