Since yield losses are expected when lodging exceeds 300, please either refrain from applying top dressing or reduce irrigation significantly.
Please refer to the graph above for the number of stems per plant converted to square meters, based on the number of plants per unit area.
Please refer to the conversion table below to convert color scale values to leaf color values (SPAD502 values).

No customer feedback for this calculation yet.
Based on plant height, number of stems per square meter, and leaf color value (SPAD502) at the onset of young spike formation (25 days before heading, young spike length 1 mm), the program calculates
at maturity.
Please note that any crop management decisions based on these diagnostic results are your sole responsibility.
