Description

In North Dakota, soybean is typically planted in mid to late May; however, a late spring frost or flooding event may cause a grower to plant late, or replant their crop. The objective of this research was to determine the influence of seeding date, cultivar maturity rating (CMR), and environment on the growth and development of soybean. Six seeding dates were established from 23 May to 9 July using soybean CMR of 00.9, 0.7, and 1.4 at Carrington, Prosper, and Lisbon, ND. The experimental design was a randomized complete block with a 6x3 factorial. The interaction of date by CMR indicated that yield decreased as seeding was delayed further into the growing season with yields becoming less than economical in soybean seeded after 22 June. Soybean with CMR of 00.9 and 0.7 are best suited for delayed seeding in North Dakota, while CMR 1.4 rapidly loses yield with delayed seeding.
