Overview

Investigates the effects of nitrogen fertilizer rates and application timing on maize yield, suggesting optimal practices.

Key Points

  • The research aims to determine the optimal nitrogen fertilizer rate and application timing to enhance maize productivity.
  • Conducted a factorial experiment with four nitrogen rates and five application timings using a randomized complete block design.
  • Performed the study in Hadero Tunto District during the 2019 cropping season.
  • Measured outcomes include grain yield and total biomass yield of maize.
  • The highest grain yield of 6.417 t/ha was achieved with 200 kg N/ha applied in a specific timing regimen.
  • Lower yields of 4.413 t/ha observed at the lowest nitrogen rate of 50 kg N/ha indicate significant differences based on nitrogen application.
  • Total biomass yield increased linearly with higher nitrogen rates, reinforcing the yield benefits.
