“…Water and nitrogen (N) management are key to improving the yield and yield stability of forage crops. Oat (Avena sativa L.) is widely used as a forage crop in this area, as it has a short growth duration and good adaptive capability to low temperature and drought [5,6]. The Tibetan Plateau is a major oat production area in China; however, the production and quality of oat forage are low and variable [7].…”

“…When water was fully supplied, proper N fertilization was needed to prevent nutrient deficiencies but too much fertilizer would result in N leaching and low use efficiency [13,22]. When water was not fully supplied, less N fertilization was usually needed to realize the water-limited maximum crop yield [6,23]. However, the interacting effects of water and N on oat forage production are rarely investigated, especially in the Tibetan alpine environment.…”

There is a great need for improving oat forage production to increase forage supply and protect grassland ecosystems on the Tibetan Plateau. We conducted two field experiments and modeling work to investigate the responses of oat (Avena sativa L.) forage yield and N uptake to water and N applications, and to optimize the water and N scheduling under rainfed and irrigated conditions. The experiments were conducted in 2017 and 2018 at Jintai farm in the northeast of the Tibetan Plateau. Two N-applying rates of 120 and 60 kg ha−1 were tested in 2017, and four irrigation treatments (no irrigation—NI, irrigated 50 mm at flowering—I1, irrigated 50 mm at tillering and jointing—I2, and irrigated 50 mm at tillering, jointing, and flowering—I3) were applied under every N rate in 2018. The Agricultural Production System Simulator (APSIM) was calibrated and validated for the local oat variety. Under rainfed conditions in both years, oat yields under high and low N were 7.98–8.52 and 5.09–6.53 t ha−1, respectively; the high N rate significantly increased forage yield and N uptake compared to low N conditions by 22.2–67.4% (p < 0.01) and 42.0–162.0% (p < 0.01), respectively. In 2018, irrigation increased oat forage yield by 29.8–96.6% (p < 0.01) and increased N uptake by 19.6–50.5% (p > 0.05); N rates had no significant effect on forage yield (p > 0.05), but significantly increased N uptake by 42.6–64.7% (p < 0.01). I2 was superior to I3 in terms of increasing water use efficiency (WUE) while maintaining high forage yield and N uptake. APSIM-oat was calibrated with data under both rainfed and irrigated conditions and was confirmed to have good accuracy and lower normalized root mean square errors (NRMSEs) for phonology dates, forage yield, soil water storage, and N uptake. Scenario analysis was performed with 30-year historical weather data; five N rates were designed for rainfed conditions, and 25 scenarios comprising five N rates and five irrigation levels were designed for irrigated conditions. Simulations showed that the N rate of 90 kg ha−1 resulted in the best performance for oat under rainfed conditions. Under irrigated conditions, irrigation promoted oat nitrogen uptake. Thus, overall an N rate of 120 kg ha−1 in combination with irrigation of 120 mm applied during the vegetative growth period performed the best. This optimized strategy may provide guidance on water and N management of oat forage production in the Tibetan Plateau and similar alpine regions worldwide. The promoted strategy increases yields while reducing water and nitrogen resource wastes, thus decreasing the environmental pollution from agriculture and responding to the sustainable development of farmland ecosystems.

“…Common vetch ( Vicia sativa L.) is an annual high-quality legume crop widely grown worldwide, especially in China, Canada, and Mediterranean countries [ 7 , 8 , 9 ]. It has received increasing attention from researchers due to its beneficial effect on the soil and contribution to maintaining ecosystems [ 10 , 11 ]. Moreover, the common vetch was found to have high levels of starch with a high gelatinization temperature and relatively low setback.…”

Three extraction methods: water extraction, lactic acid bacteria fermentation, and back-slopping fermentation were applied to extract a new type of legume starch, common vetch starch. Our results showed that the lactic acid bacteria fermented starch had the highest amylose content (35.69%), followed by the back-slopping fermented starch (32.34%), and the water-extracted starch (30.25%). Furthermore, erosion surface, lower molecular weight, smaller particle size, larger specific surface area, and a higher proportion of B1 chain were observed in the fermented starch, especially in the back-slopping fermented starch. All the extracted starches showed a type C structure, but a type CB structure was observed in the back-slopping fermented starch. In addition, the relative crystallinity of the lactic acid bacteria fermented starch (34.16%) and the back-slopping fermented starch (39.43%) was significantly higher than that of the water-extracted starch (30.22%). Moreover, the swelling power, solubility, pasting, and thermal properties of the fermented starches were also improved. In conclusion, the fermentation extraction method, especially back-slopping fermentation, could improve the quality of the extracted common vetch starch when compared with the traditional water extraction method.
