“…Winter cover crops can provide additional economic value and incentive for producers to adopt this practice. Winter cereal cover crops can be successfully utilized as a spring forage source [60][61][62]. The impacts on the subsequent cash crop can be variable, however.…”

Ecological Intensification of Food Production by Integrating Forages

Forage crops have the potential to serve multiple functions, providing an ecological framework to sustainably intensify food production, i.e., ecological intensification. We review three categories of forages (annual forages, perennial forages, and dual-use perennial crops/forages) we believe hold the greatest promise for ecologically intensifying food production. Annual cover crops can provide additional forage resources while mitigating nutrient losses from agricultural fields when they are intercropped with, interseeded into, or following an annual crop, for instance. The integration of perennial forages either temporally, such as annual crop rotations that include a perennial forage phase, or spatially, such as the intercropping of perennial forages with an annual cash crop, provide weed suppression, soil quality, and yield and crop quality benefits. Dual-use crops/forages can provide forage and a grain crop in a single year while providing multiple ecological and economic benefits. However, tradeoffs in balancing multiple functions and limitations in reducing the risks associated with these practices exist. Advancing our understanding of these systems so we can overcome some of the limitations will play a critical role in increasing food production while promoting positive environmental outcomes.

“…Cover crops deliver multiple ecosystem services [1], such as reduced nutrient leaching [2,3] through nutrient uptake [4], reduced soil erosion [5], enhanced soil fertility [6] and improved soil-water dynamics [7], weed suppression [8,9], and forage production [10]. Cover crops are promoted as a best management practice to avoid water quality impairment [11] and as a soil management tool [5], but their adoption remained low by the mid 2010s [12].…”

The incorporation of cover crops into the maize (Zea mays L.)-soybean [Glycine max (L.) Merr.] rotation in the U.S. upper Midwest may improve sustainability. Long, cold winters in the region make identifying successful cover crop species and management practices a challenge. Two experiments were conducted in Minnesota, USA from fall 2016 through spring 2019 to examine the effect of cover crops interseeded at four-to six-leaf collar (early-interseeded) and dent to physiological maturity (late-interseeded) on biomass and grain yield of maize. Annual ryegrass (Lolium multiflorum L.) and cereal rye (Secale cereale L.) were evaluated as monocultures and in mixtures with crimson clover (Trifolium incarnatum L.) and forage radish (Raphanus sativus L.). Differences in canopy cover and biomass of late-interseeded cover crops were observed at the southernmost location in 2018. Additional accumulated growing-degree days in fall 2018 did not translate into increased cover crop canopy coverage of late-interseeded cover crops. Differences in cover crop canopy cover and biomass of early-interseeded cover crops were observed by fall frost at all locations in 2017 and at the northernmost location in 2018. Cover crop canopy cover and biomass at termination before planting maize, soil moisture at maize planting as well as maize aboveground biomass and yield were not affected by spring cereal rye regrowth of cover crops late-interseeded the previous year. Similarly, early-interseeded cover crops did not affect maize aboveground biomass or yield. We attribute these results to limited cover crop growth. This highlights the potential of a variety of cover crop strategies interseeded into maize in the U.S. upper Midwest; however, efforts to fine-tuning cover crop management and weather conditions are needed to benefit from such practice.

“…Dhillon et al (2019) recognized that CP content was decreased with increase in age of crop plant. Landry et al (2019) reported that winter cereal cover crops such fase de grano lechoso, el rendimiento de forraje verde y de materia seca fue mayor en N 3 C 3 en comparación con el resto de los tratamientos, seguido de N 2 C 3 durante los años consecutivos Las plantas tratadas con dosis de nitrógeno de primer nivel tienen más hojas y, por lo tanto, producen la mayor relación hoja/tallo, lo que conduce a un máximo rendimiento de forraje verde. En contraste con nuestros hallazgos, Khan et al (2014) reportaron que bajo condiciones agroclimáticas de Sargodha, Pakistán, los mayores rendimientos de forraje en la avena pueden deberse probablemente a su mayor área foliar, responsable de una mayor eficacia fotosintética, teniendo una alta aptitud para acaparar productos asimilables de la fotosíntesis.…”

The farmers of hilly areas face severe fodder shortage in winter season except to have only dry stalks of summer cereals. The study aimed to evaluate the adaptability of winter forage cereals (barley, oats, rye and triticale) and to quantify the suitable dose of nitrogen (0, 75, 150 and 225 kg.ha-1) for the assessment of bio-metric and qualitative characteristics of winter forage cereals (WFCs) at booting stage (BS) and milking dough stage (MDS) grown under temperate conditions. Two years (2016-2017 and 2017-2018) field trials were executed at the University of Poonch Rawalakot, Pakistan. Harvested forage then preserved as silage by adding Formic acid and Molasses as additives at the rate of 5 kg.t-1. Rye crop in conjunction with 225 kg.ha-1 nitrogen out yielded greater plant height which led to the highest green fodder (55413 and 43542 kg.ha-1) and dry matter yield (188471 and 12440 kg.ha-1) during consecutive years 2017 and 2018, respectively. Whereas, oats cultivar performed better for fresh weight, dry weight and leaf area per plant. More crude protein contents were recorded for triticale crop at N3 level with use of molasses during both the years at both cutting stages (booting and milking dough). More crude fibre was noted in barley crop at control level of nitrogen fertilization on both booting and milking dough stage. The correlation analysis revealed direct interrelationship among yield attributes and fodder yield of winter forage cereals and thus indicating the need to supply nitrogen at the rate of 225 kg.ha-1 for improving biometric characteristics of WFCs.
