📘 Screen: Variety/Cultivar
The Variety/Cultivar screen is used to register the cultivars of each crop grown on the farm — TMG 31 B3RF for cotton, NEOGEN 690 I2X for soybean, P3845VYHR for corn.
This information complements the Crop record and is essential for Season Planting, allowing more precise control of production and of the agronomic behavior of each genetic material.
📍 Location in the system
Menu: Crops > Variety
🧩 Main function
Each registered variety can be linked to:
- A specific crop
- One or more season plantings
- Technical information such as cycle, yield, weight and germination
📝 Record fields
| Field | Description |
|---|---|
| Name/Description | Name of the cultivar, as the market calls it (e.g. TMG 31 B3RF, VORAZ IPRO). |
| Code | Identifier for the variety. |
| Crop | Required. The crop this cultivar belongs to. |
| Color | Used on maps and dashboards to represent plantings of this variety. |
| Cycle Days | Length of the cycle, in days — the basis for the harvest forecast. |
| Days to flowering | Days until flowering. |
| Technology | Conventional, Transgenic or Other. It comes checked as Conventional. It is for information only and makes no difference in other features. |
| Active | Sets whether it is available for use. |
| Reference/Integration ID | This variety's code in the external system, when there is an integration. |
| John Deere ID | The matching identifier on the John Deere platform, used by the machine integration. |
| Notes | Free-text field at the end of the form. |
The list, on the left, shows Code, Name/Description, Crop, Cycle Days, Technology, Active, Macro, Generation, Strategy, Color and Reference/Integration ID.
🌾 "Harvest" section
A collapsible section with three Estimated weight (KG) fields — 1, 2 and 3. These are the yield estimates for that cultivar.
🌱 "Planting" section
Also collapsible, it gathers what guides planter calibration:
| Field | Description |
|---|---|
| Sieve (PN) | Seed sieve size. |
| Thousand-seed weight (PMS) | Weight of a thousand seeds — used to calculate the amount of seed per hectare. |
| % Germination | Germination rate stated on the seed lot. |
| Plants / M | Target plant population per meter. |
| Seeds / M | Seeds per meter to drop, taking germination into account. |
| KG/HA | Kilograms of seed per hectare. |
📈 Tab: Ideal Veg. Growth
Just like on the Crop screen, you can define the expected development curve — except here it is per cultivar, which is where differences in behavior really show up. Each line has:
- D.A.E. — days after emergence
- Plant Height
- No. of Nodes
These values are used in scouting to check whether development is within the expected standard.
Tab buttons:
- View chart: shows the registered growth curve
- Import: copies the curve already built for another variety
- Generate in bulk (height): fills in several DAEs at once — enter Start D.A.E, End D.A.E and Height per D.A.E
- Delete all: clears the whole curve, so you can start over
- You can use them in season plantings
- Scouting can be assessed against the ideal behavior
- The system will be able to produce more accurate harvest forecasts and reports
❓ Frequently asked questions
Do I need to register the variety to plant?
Yes, and it must be linked to a crop — choosing the crop is required in the record. The variety is what lets you track the behavior of each genetic material on the farm.
How does the system estimate the harvest date?
Using the variety's Cycle Days field, which states how many days that cultivar takes to complete its cycle. There is also Days to flowering, to track that stage.
Does the variety's technology (transgenic/conventional) change anything in the system?
No. The Technology field is for information only — it does not change how other features behave.
Where do I enter the cultivar's thousand-seed weight and germination?
In the Planting section of the variety record, which expands and collapses just below the main fields. That is where Sieve (PN), Thousand-seed weight (PMS), % Germination, Plants / M, Seeds / M and KG/HA are. Yield estimates are in the neighboring section, Harvest.
What is the ideal vegetative growth for?
For comparison during scouting. You define the expected plant height, number of nodes and days after emergence (DAE), and the system uses those values as a reference for what was collected in the field.
Do I have to build each cultivar's growth curve by hand?
You don't. On the Ideal Veg. Growth tab, the Import button copies the curve from another variety and Generate in bulk (height) builds the whole sequence from the start DAE, end DAE and height per DAE.
