The timing of the ending R stages in soybean is governed by planting date (PD) and varietal maturity group (MG), though the date of R7 can be hastened if water stress and high temperatures prevail in August — something we are seeing in portions of Nebraska this year.
This Nebraska Extension indoor study offers a comprehensive analysis of the timing and duration of the critical imbibition water uptake phase for soybean, to assist growers in their decisions on planting dates this spring.
The heat and drought in areas of the State are rapidly moving Nebraska’s 2020 soybean crop along. Growers have been asking how to determine late season growth stages for last irrigation of the season and for determining maturity.
The weather took a turn to the cold side over the last week. Across Nebraska, lows at or below 32°F were recorded. Clear conditions coupled with these temperatures favor frost formation especially in low lying areas. So, what does this mean for our crops?
