| Abstract/Contents: | "Switchgrass (Panicum virgatum) is a perennial warm season grass (C4) native to most of the US with the exception of some Northwestern states. Switchgrass has been used in restoration, buffer strips, as a forage crop, and as an ornamental, but is now emerging as source of alternative energy due to its native status, perennial life cycle, ability to grow on marginal land, and high yields with little inputs. However, little information is available on switchgrass yields in the northeastern US. The objectives of this study were to determine and compare yields of four switchgrass cultivars and corn (zea mays) at two locations in New Jersey. Four switchgrass cultivars (Alamo, Carthage, Cave-in-Rock, and Timber) and corn were planted in a randomized complete block design at two locations: Pittstown, NJ and Upper Deerfield, NJ in spring of 2007. Due to establishment failure, the Pittstown location was replanted in spring of 2008. Switchgrass plots were established at a rate of 10lbs PLS/acre. Locally grown Round-Up ready corn varieties were planted at each location at a rate of 28,000 seeds/acre. During establishment, irrigation was applied to promote germination and 2,4-D and dicamba were used to control broadleaf weeds. No herbicides or supplemental irrigation were applied in years 2 and 3. Both trials were managed for switchgrass production and received 50lbs N/acre applied in mid-May of each year. A single fall harvest and separated to determine plant biomass and grain yield. Biomass yields for switchgrass ranged from 3.9 to 5.9 tons/acre. Corn grain yield under switchgrass management ranged from 46.6 to 53.1 bushels/acre. This was 19 to 32% lower than corn managed for corn production (adequate irrigation and 100 lbs N/acre). Cultivars Tumber, Alamo, and Carthage had the highest yields at both locations. Conversion of biomass yields to ethanol yields resulted in 18 to 66% higher yields in swithgrass than corn grain and stover combined at both locations. Results found suggest that once an infrastructure for cellulosic ethanol is established, Timber and Alamo could be promising cultivars for biomass production in NJ as an alternative to corn." |
