Assessment of Macro and Micro Nutrients in Soil and Yield Attributes of Maize (Zea mays L.)

Abstract

The soil science central research farm at Sam Higginbottom University of Agriculture, Technology and Sciences located in Prayagraj carried the experiment on the field during the Kharif season of the year 2022. The soil of experimental field is sandy loam in texture.  The plan involved using randomized block design to apply varying degrees of both large scale NPK supplements at concentrations ranging from (0%, 50% and 100%) as well as miniature Zn and Fe supplements also ranged from (0%, 50% and 100%). The significant results were found in T9 were organic carbon%, available nitrogen, available phosphorus, available potassium whereas we observed effective use of nutrient supplements growth and yield attributes are moderately in T9 gave the best outcomes concerning plant height, no. of branches, no. of seeds, seed weight and yield. The study recommended using natural excrements alongside with full dose of NPK Additionally, utilizing both 100% large-scale and 100% miniature supplements together has the greatest impact on maize growth when compared to any other.
