Conservation Tillage: Cover Crops


Photo: PigeonpeaPigeonpea is a summer annual legume that is slow to germinate but fast to grow once established (similar to velvetbean). It suppresses weeds as a mature plant, but needs outside weed control until the plant reaches maturity. Pigeonpea is susceptible to nematodes. It is highly drought-resistant, having a deep taproot, and can grow on infertile soils. It produces large amounts of biomass and fixes nitrogen around 50 lbs/ton of dry matter (dry matter produced at 2.5 tons/A). It can be used as a forage and for wildlife consumption, while the grain can be used for human consumption and as an alternative fuel source.
