Silage Corn Hybrid Response to Row Spacing and Plant Density.

Silage corn is an important feed for dairy cattle in the Intermountain West and harvested acreage has increased greatly over the past decade. Research on corn production practices has been common in the Midwest and eastern regions of the US, but is rare in the high desert conditions of the West. The objective of this research is to determine the optimum plant population and row spacing for silage corn production in the Intermountain West. Studies were conducted in 2015 at Logan, UT and Jerome, ID. The experimental design was a randomized complete block split-split plot with four replications. The whole plot treatment is hybrid (3), the sub-plot treatment is row spacing (2), and the sub-sub plot treatment is plant density (6).
