Enhanced Efficiency Liquid Nitrogen Fertilizer Management for Corn Production
Table 5
Chlorophyll meter readings, plant population, grain yield, moisture, protein, and oil concentration response to nitrogen sources/placements at 168 kg·N·ha−1. Data were combined over factors or years in the absence of a significant interaction. Surface treatments were no-tillage with surface applied nitrogen and deep treatments were strip tillage with deep banded nitrogen application.
