Trial Name: 2020 Cover Crop Mix Trial

Description

Eight cover crop blends were subject to a nutritive analysis.  There were significant differences in many of the nutritive indicators measured including dry matter (P=0.002), crude protein (P=0.001), TDN (P=0.02), and phosphorus content (P=0.03). ADF (P=0.18) and calcium (P=0.06) were statistically similar between treatments. NPARA Blend #6 produced 2.6 tonnes/acre of dry matter, the highest of any treatment. NPARA blends #4 and #1 had the highest level of crude protein at 33.4% and 31.5%, respectively. NPARA Blend #1, 75.1%, and Pinpoint Blend, 74.7%, exhibited the highest TDN. C.V. values were high for all except ADF and TDN.
