Plot Weather Profiles
In August 2020, we asked the FIRST community what would add value to our yield trial reports each season. The overwhelming majority (69% of respondents) answered that they want the plots' local weather profile added.
As a result, FIRST is pleased to announce that plot weather will now appear in 2021 FIRST Top 30 Harvest Reports. Rainfall and GDU totals for each month and the season are summarized at the top of the weather page. A convenient weather graphic displays rainfall events and accumulation, GDUs, and temperatures compared to normals for the entire season from planting to harvest.
For corn grain, estimated mid-pollination and maturity dates are indicated using the relative maturities in the test and accumulated GDUs.
The weather data is derived from the highly regarded PRISM dataset, a publicly available source of climate observations. PRISM integrates weather information from multiple sources and models to create a spatially complete dataset at 4 km resolution for the lower 48 states.
Product Results Links
We have added another feature to both the Top 30 Harvest Reports and Top 30 Region Summaries: links to each seed product's full results report at www.firstseedtests.com. FIRST Seed Product Search was launched last year and provides a summary report for seed products with all yields — across all years — in FIRST tests. The report includes locations where the product was tested on an interactive map and allows you to sort or search tabular results for particulars like tillage, fertilization, and soil type.

Thanks to the excellent FIRST community for their continued feedback, helping us improve the information we provide for producers and the seed industry.
