Effect of Row Spacing and Plant Density on Silage Maize Growth, Dry Matter Distribution and Yield

Maize growth in narrow rows provides a more uniform spatial arrangement, but it does not always lead to increasing yield. A four-year study was conducted investigate the effect of row spacing on silage maize and yield during growing season at harvest time. field experiment with conventional (0.70 m) (0.35 plant density 92,000 plants ha−1 evaluated years 2011–2014, interaction × (92,000 110,000 ha−1) tested 2013–2014. The clearly demonstrated potential support height weight development, together higher stalk proportion, around two months after seeding. However, these contrasts were lost later stages Some for non-significantly dry matter (4.6–10.8%) shown three experiment, association lower losses numbers, when compared spacing. improvement showed relationships weather conditions second half season. In summary, under region, significantly promoted early effects did persist until harvest, thus resulting only limited success improvement.
