Manage Field Variability in Soybean Crops

Two men looking at CROPLAN seed bags

Variability is common on farms, which can make it tricky to purchase the right soybean seed for a particular field. But there is a solution: the combination of two different soybean varieties that’s offered in CROPLAN® WinPak® varieties.

These unique combinations of both offensive and defensive varieties provide an exceptional level of stability, working together to increase yield potential on tough acres while maintaining yield potential in higher-producing areas.

Manage diversity, mitigate risk

Getting two different soybean varieties in one bag allows you to place genetics in fields that normally wouldn’t be hospitable toward certain varieties if they were planted alone. Planting a WinPak variety allows you to hedge your bets with either a defensive variety or an offensive variety, and to plant on multiple soil types and fields with varying stress loads.

What we select for

WinField United chooses seed that’s complementary in terms of agronomic features, such as region-specific disease tolerance, heat and drought tolerance, standability, and yield potential. We select maturities carefully so the two varieties have a consistent drydown in the field, which helps eliminate harvest timing issues. Our seed pairings are strategic and carefully formulated to provide you with optimal performance in your specific region.

Data-based pairings

Many WinPak varieties are tested across the country through the Answer Plot® program and in Insight trials, with up to three years of data behind them to prove consistency of performance. Thousands of data points provide you with a unique opportunity not only to judge performance based on yield, but also to consider maturities, shatter scores and lodging potential in your decision-making to get the best defensive packages with the highest yield potential.

A premium pairing of soybean seed varieties can provide a consistent boost to yield potential that is otherwise hard to find. In fact, 2016–2017 data from regional Answer Plot® trials show WinPak varieties consistently outperformed their individual component varieties by 2.1 bushels per acre. Removing the highs and the lows and making a more consistent soybean combination can help ensure more reliable performance overall.

Regionalized soybean formulations and new WinPak offerings

At WinField United, we pride ourselves on offering highly localized seed for the acre. So, as a result of regional demands, we’ve upgraded some WinPack varieties and replaced others. For example, in an area where many farmers plant soybeans followed by soybeans, we might have disease pressures — e.g., frogeye leaf spot, stem canker and brown stem rot — that are specific to that environment and that call for more defensive soybean traits. Other regions may require WinPak varieties with greater yield punch and more offensive traits. We are also expanding our portfolio of WinPak varieties. This year, in the 2.5 to 5.0 maturity group, we will offer 14 new and five upgraded WinPak varieties across the country.

What we’ve realized is that, even on high-producing, high-organic-matter soils, having some genetic diversity in the field — and a defensive or offensive mechanism, depending on the circumstances — has given farmers a yield bump. What started out as a product to correct defensive acres has evolved into a seed combination that’s effective on both offensive and defensive acres.

WinPak varieties can help you capitalize on your top-end yield potential in the better areas of the field and offer solid defense in areas where you have greater variability in soil type. They can also help balance the variability inherent in other factors that affect overall yield potential, such as weather challenges.
