Northeast Research and Demonstration Farm
Starter fertilizer often increases early-season growth of corn. However, grain yield responses to starter fertilizer are variable. Plant-to-plant variability in growth and grain has been shown to have negative impacts on total grain yield. Our objectives were to measure plant-to-plant variability as affected by starter fertilizer, hybrid, and population. We also studied the impact of starter fertilizer on growth, development, and grain yield of hybrids and populations.
