“…Cereal cover crops have been shown to be effective in reducing weed biomass, but growers are concerned that cover crops could reduce the tiller density and biomass production of the cash crops as well [47,48]. Sadeghpour et al reported rye is an excellent crop to control weeds, but found lower switchgrass tiller density in rye but improved switchgrass tiller density with oat, in line with findings of this study [28].…”

“…Previous research in Massachusetts indicated that oat, when planted early, is able to accumulate a great amount of biomass [19] and, when terminated by frost, can cover the soil but does not induce immobilization; therefore, it allows the cash crop to be established. Over-wintering cover crops such as rye and wheat, if not terminated early (this was the case in our study), can severely tie up N, use water and reduce the cash crop's establishment and production [47][48][49][50]. These reasons explain the differences between oat and rye in improving switchgrass tiller density.…”

“…One strategy to avoid such an issue is to skip the cash crop row when planting rye. This decreases the intersecting zones between a cash crop and the rye cover crop, and improves the cash crop's establishment [48].…”

Establishment of switchgrass (Panicum virgatum L.) is challenging, and failure in establishment may expose growers to considerable economic risk. The objectives of this research were to (i) evaluate whether management practices are variety-specific for the establishment of switchgrass and (ii) assess the effectiveness of cover crops as preceding crops on ‘Shawnee’ switchgrass establishment. Therefore, two studies were conducted at the University of Massachusetts Agricultural Experiment Station in Deerfield, MA, USA, in the 2011–2012 and 2012–2013 growing seasons. In Experiment 1, cover crop treatments (fallow, oat (Avena sativa L.) and rye (Secale cereale L.)) were the main plots, the two seeding methods (no-till drill and a cultipacker seeder (Brillion)) were the sub-plots, and the two varieties (‘Cave-in-Rock’ (CIR) and Shawnee)) were the sub-sub-plots. The second study was conducted using Shawnee switchgrass and involved the three cover crop treatments used in Experiment 1 using a cultipacker seeder with seed firming prior to planting but not afterwards (consistent in both experiments). The results indicated that a combination of oat and no-till resulted in higher tiller density (493%), lower weed biomass (77%), increased switchgrass biomass (SGB) (283%) and SGB to weed biomass (WB) ratio. Compared with Shawnee, CIR planted into a winter-killed oat residue had higher tiller density (93%), lower weed biomass (18%), higher switchgrass yield (128%) and thus a greater SGB:WB ratio (507%). Trends of switchgrass response to management practices, however, were similar between the two varieties, indicating that seed quality rather than management practices could influence switchgrass’s response to management practices. In Experiment 2, Shawnee tiller density was suppressed by rye as the preceding crop, possibly due to late termination of rye. Shawnee switchgrass yields were below 1000 kg ha−1 under all management practices; thus, harvesting should happen in the year following establishment. Future research should focus on comparing no-till drilling with cultipacker seeder with rolling not only before but after seeding to increase seed–soil contact.

“…The partial budget analysis confirmed that by excluding yield penalty for corn after WCR from the production costs, double cropping WCR with corn is feasible in four out of five site-years even at hay price as low as $110 Mg −1 . Improved agronomic management practices such as precision planting of WCR (skipping the corn rows) are capable of minimizing the negative effect of WCR on the following corn crop yield (Sadeghpour et al, 2021). Eliminating the cost of nutrient removal (typical in concentrated dairy farms with excess nutrients) made WCR forage production feasible at all site-years at a hay price of ≥$110 Mg −1 .…”

“…One major component of agronomic management for WCR forage production is harvest date because dry matter (DM) yield and quality rapidly changes in the spring. Previous reports show that WCR can produce 2-4 Mg DM ha −1 in the Northeast and Midwest United States when harvested at the boot stage (Kantar et al, 2011;Ketterings et al, 2015;Sadeghpour et al, 2021). However, when the date of harvest is delayed from boot stage to soft dough stage, a 30-60% yield increase in winter cereals DM yield is expected (Collar & Askland, 2001;Helsel & Thomas, 1987;Edmisten et al, 1998;Lyon et al, 2001).…”

Harvesting annual winter cereal rye (Secale cereale L.) (WCR) as an emergency forage could offset cover crop establishment costs, facilitate WCR adoption, and still provide multiple ecosystem benefits. A five site-year trial was conducted in Colorado (CO) and Illinois (IL) to evaluate the effect of harvest date on WCR forage yield, quality, and its economic performance. From March to April, WCR dry matter (DM) yield increased exponentially in CO and linearly in IL. The DM yield at Julian day (DOY) 112-116 in CO was 6.9, 5.0, and 5.2 Mg ha -1 in 2018, 2019, and 2020, respectively, compared with 4.7 and 2.7 Mg ha -1 in IL in 2019 and 2020, respectively. Delayed harvesting increased acid detergent fiber and neutral detergent fiber concentrations and decreased crude, total digestible nutrients, and relative feed quality. Yield-quality trade-off showed that forage yield increased rapidly but forage quality declined after DOY 105-108. Economic analysis, including cost of nutrient removal and 10% cash crop (corn [Zea mays L.]) yield penalty following WCR production revealed harvesting WCR biomass as forage was economically feasible in four out of five site-years at hay price over $132 Mg -1 . Eliminating corn yield penalty indicated profitability in four site-years at hay price of ≥$110 Mg -1 and removing nutrient removal costs made all site-years profitable at hay price of ≥$110 Mg -1 . It was concluded that harvesting WCR biomass can be a profitable and effective strategy for sustainable intensification that can offer environmental stewardship and economic benefit. INTRODUCTIONWinter cereals have shown to be excellent cover crops in various agroclimatic conditions (Kaspar & Bakkar, 2015).

Cover crops can be a great addition to agricultural systems to improve soil health and nutrient cycling. One of the many qualities that cover crops possess is recovering residual nutrients. This study was established to estimate daikon radish (Raphanus sativus var. Longipinnatus) nitrogen (N) uptake, partitioning, and accumulation in a short time in Florida conditions. In greenhouse conditions, two Florida sandy soils were planted with daikon radish with three N rates (0, 50, and 101 kg N ha−1 as urea) following a randomized complete block with four replications. The treatments were organized in a two‐by‐three full factorial arrangement with the three N fertilizer rates. Biomass accumulation, N uptake, and partitioning into shoots and roots were estimated, and residual soil N was calculated. Increasing the amount of N applied to daikon radish plants did not increase biomass production or N accumulation in the shoots and roots of the plants. Daikon radish plants grown without N fertilization were able to produce a similar amount of biomass as those with N applications in their early growth stage. This suggests that daikon radish has the potential to adapt to the sandy soils of Florida and could efficiently utilize the residual soil N. This study shows the potential use of daikon radish as a cover crop in the row middles of citrus groves. The findings suggest that daikon radish plants could thrive in these unfertilized areas and offer promising benefits to the citrus orchards in terms of providing ground cover and additional advantages.
