Abstract

Maize is exhaustive crop and hence requires integrated approach for nutrient management. To address the same, Pink pigmented methylotrophic bacterial (PPMB) culture was applied as solid and liquid formulations (Basal and split) along with 100 % and 75 % RDF in maize. A field experiment was conducted during the summer season of 2021 at Shivamogga. The experiment was laid out in a randomized complete block design having twelve treatments with three replications. Among the treatments tested, application of 100% RDF + PPMB (Basal application of either solid/liquid formulations or split application of liquid formulation) recorded significantly higher plant height (206- 208 cm), leaf area (6100-6600 cm2), dry matter (284- 297 g plant-1), cob length (14- 15 cm), number of grains cob-1 (516- 543). By virtue of above parameters, said treatments recorded maximum grain (6167 to 6235 kg ha-1), straw (8209- 8410 kg ha-1) yield.

Keywords

PPMB, Solid, Liquid, Basal, Split, Maize, RDF.

Conclusion

As a part of integrated nutrient management, it was found that use of PPMB (Basal or Split application of liquid formulations and Basal application of liquid formulations) along with 100 per cent RDF recorded higher plant height, leaf area, dry matter, yield parameters and grain yield.
