Response of Inorganic Fertilizers and Vermicompost on Growth and Yield of Maize (Zea mays L.) Inoculated with Azotobacter, var. DHM-1

Abstract

The field experiment was carried out at central research farm of Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Kharif season year 2022-2023. The experiment was comprised of 9 treatments with 3 level of NPK and Vermicompost in randomized block design. The treatment T9 has shown the significant results when applied 100% of NPK with Vermicompost among the different levels of treatment combination. Growth parameters viz., plant height (171.10 cm), number of leaves plant-1 (14.65) at 90 DAS (day after sowing), and yield parameters viz., length of cob (24.73 cm), number of grains cob-1 (308), test weight (218.46 g), grain yield (46 q ha-1) has shown best in treatment T9 (NPK @ 100% + Vermicompost @ 100%) of maize (Zea Mays L.) in comparison to other treatment combination.
