A research project in eastern Nebraska is evaluating a double crop production system as a potential alternative to the traditional corn/soybean rotation. Following an early season crop of yellow field peas, short-season crops (corn, soybean, grain sorghum, millet and sunflower) and annual forages (forage sorghum and sorghum-Sudangrass) were planted.
While continuous corn is the most common cropping sequence in southwest Nebraska, adding soybeans to a rotation could help break pest cycles. On-farm research comparing 15- and 30-inch soybean row spacing found increased yields of 4-12 bu/ac with an average 7 bu/ac increase with 15-inch rows.
Learn about and engage with the expanding pulse crop industry at two events being held in western Nebraska this month: the Pulse Crops Workshop Jan. 17 at Bridgeport and the Pulse Crops Expo Jan. 18 at Grant. Check the agendas and register for one or both events by Jan. 16.
Field day participants will be able to view field pea varieties and learn about rotational benefits and agronomic practices to profitably grow field peas and integrate them with existing cropping systems.
Most yellow field pea being grown in western Nebraska were at early vegetative stages (4th to 7th node or 1-5 leaf stages) during last week’s cold snap, but extensive damage is not expected due to the pea’s level of frost tolerance.Field pea tolerance to frost during early stages of vegetative growth is partially due to the “hypogeal” germination nature of the crop. For plant species with hypogeal germination (e.g., field pea, lentil, chickpea), shoot germination occurs belowground.
Grain-type field peas are a cool season grain crop grown as an alternative for no-till summer fallow in a semiarid cereal-based cropping systems such as wheat-corn-fallow and/or wheat-fallow. They are typically planted in mid-March and harvested late-July. This article reports on research conducted on seeding practices and offers recommendations for producers on the economically optimal seeding rate, seeding depth, and inoculant to grow field peas in western Nebraska.
