NSC Leroy
RR2Y
Emergence
NSC Leroy RR2Y is a super ultra early maturing variety that will be the earliest soybean variety in Western Canada. This is definitely the variety of choice for new soybean growers in Saskatchewan in the black soil zone. This variety has a plant growth structure that’s fairly tall and upright.

NSC Watson RR2Y is an ultra-early maturing variety and is suitable for the black soil zone of Saskatchewan as well as dark brown and brown zones. This variety exceeded our expectations with very strong earlyseason vigour and very good height due to extended lower internode. Its characteristic leaf shape makes NSC Watson RR2Y easy to identify.

NSC Reston RR2Y has become the variety of choice for soybean growers in western Manitoba and eastern Saskatchewan. In all our demonstration plots and thirdparty variety trials, NSC Reston shows very consistent and competitive yields. With NSC Reston RR2Y, you get very early maturity plus very good yield as this variety has been reported to yield over 50 bushels per acre by many growers.

NSC EXP 114 RR2X is the first early maturing soybean variety with the new Xtend trait, allowing growers to use glyphosate and dicamba for extended in-season weed control. Tall grower habit with good yield potential. A must for growers who need to manage their use of glyphosate to prevent resistance. Does well in reduced tillage.

Soybean Maturity and Low Temperatures Minimum temperatures for soybean seed ripening has been shown to be 8-9°C and optimum being 19-20°C1. Cool temperatures (<10°C) during seed fill can negatively affect soybean yield through reduced seed size although the most serious impact may be delayed maturity. As beans move from R-6 (full seed) to R-7 (early maturity), the risk of yield loss from frost declines. Soybeans are normally in the R-6 stage for 18 days but can be as long as 30 days. When night-time temperatures dip below 5°C, there is a risk for low-lying areas to see a light frost. The impact of frost will depend on the nighttime low and how long that temperature is sustained. Other factors such as soil moisture (moisture in the soil will maintain heat), cloud cover (cloudy is better) and wind speed (windy is better) can also impact the degree of frost. Further, soybeans in narrow rows and thick canopies are able to maintain ground heat longer. A light frost (0 to –1°C) may kill top leaf growth but should not affect pods and seeds. Temperatures below –1°C for an extended time period will cause damage to green stems, pods ands seeds, reducing yield and quality. Maximum yield loss would occur in soybeans at R-5 (early seed).
