What this means for your programme
A November harvest description belongs to the source setting. It is not a fixed duration after planting, and a generic GDD total cannot replace the photoperiod response.
Planning interpretation by soil.ag, based on the profile below.
Where it fits
Northeast and upper North. Aromatic grain; some drought tolerance and acid/saline-soil adaptation reported without stress thresholds.
What to watch
Weak straw. Susceptible to orange-leaf disease, bacterial leaf blight, blast, ragged stunt, brown planthopper, green leafhopper and stem borers.
These are historical variety descriptions. Check local scouting and current advice; a resistance claim does not rule out a problem in your field.
Use the calendar correctly
Around 25 November in the source setting. Source calendar date; not a fixed duration after planting.
Record sowing, transplanting and observed stages separately so comparisons use the same clock.
What does the yield reference tell us?
Official release-profile yield reference; site, season, input treatment and grain moisture are not fully specified here. Not a national average, field forecast or promised yield.
A yield figure alone does not identify the right fertilizer rate. Compare records with their soil, water, inputs and harvest basis attached.
Can I use GDD for this variety?
Day length is part of this variety’s development. Accumulated heat can describe the season, but a single GDD total cannot substitute for its photoperiod response.
