This row unit utilizes an improved multi-zone, multi-functional stalk roll, which contains a novel revolving entry window to improve entry and increase engagement of the fluted portion of the stalk roll flutes with the corn stalk. The stalk rolls described are multi-sectional and contain multi-length variable flutes. The number of flutes described for each zone may vary as well as whether the flutes are meshing or non-meshing and angled or non-angled. The stalk rolls described allow a constant speed drive shaft to create lower and / or higher effective circumferential contact speeds within each zone of the stalk roll. The invention provides that the rotating transport vanes located on the helical nose cone at the entry area to the stalk roll flutes lock the corn stalk into a revolving entry window. This novel row unit contains a multi-zone, multi-functional stripper plate that ensures minimal ear wedging and maximum discharge of material other than ears. This row unit utilizes a novel gathering / conveying chain(s), which reduces the number of and increases the angle and size of the paddles. This row unit design optimizes operation between the components imparting force to the corn plant and ears. The invention has a smooth uninterrupted improved flow of corn stalk material through the ear separation chamber and is the first row unit designed to be environmentally friendly by ensuring that the majority of the corn plant remains connected to its original root system which prevents it from rapidly decomposing, blowing or washing away. The row unit cover is spatially designed for improved flow in down, damp and tough harvesting conditions.

The invention relates to a plant stress-resistant inducer, which takes Chitosan oligosaccharide solution as an effective active component.
