Topping corn and delaying harvest for field drying
1982
Allen, R.R. | Musick, J.T. | Hollingsworth, L.D.
The tops of maize plants were removed above the ear at physiological maturity to determine if that practice would hasten field grain drying in a semi-arid climate. Topping lowered the grain moisture content 1.5 percentage points below that of non-topped maize until the grain had dried to about 20% moisture content. Topping reduced lodging if harvest was delayed but had no significant effect on combine harvested grain yield. Delaying harvest until the grain moisture level had fallen below 20% reduced harvestable grain yields. However, the yield reduction was minimized if the Southwestern corn borer was controlled by spraying.
