Double Cropping Pulses with Short-Season Crops, Forages, and Cover Crops in Eastern Nebraska September 6, 2018

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.
