“…In this study, the positive effect of milk vetch on the subsequent rice crops is in agreement with results from Yu et al [23] and Zhu et al [17], which showed a 5-10% yield increase by including legumes such as bean or vetch in a rice-winter crop system. Similar positive effects on rice yield have been observed in multiple cropping systems such as rice-Azolla [24] and rice-fish [25].…”

“…Effects of cover crops on the succeeding crop yields have been studied in various cropping systems around the world [9,[15][16][17]. In most cases, leguminous cover crop species, such as alfalfa, red clover, and crimson clover, exhibit a positive effect on grain yield of subsequent corn or winter wheat in corn-cover crop and winter wheat-cover crop systems [18][19][20].…”

“…In most cases, leguminous cover crop species, such as alfalfa, red clover, and crimson clover, exhibit a positive effect on grain yield of subsequent corn or winter wheat in corn-cover crop and winter wheat-cover crop systems [18][19][20]. When it comes to rice, some studies reported grain yield increased following cover crops such as milk vetch, Sesbania rostrate, and Aeschynomene afraspera [17,21,22]. It is widely thought that the yield increase is the result of a better synchrony of N supply from the cover crop residues with main crop N demand.…”

“…The results of yield components analysis indicated that a greater rice plant panicle number was the only factor affected by milk vetch and fertilizer rate, rather than number of spikelets panicle −1 , grain filling, and grain weight ( Table 3). This implies that rice grain yield increase by milk vetch was a result of more vigorous growth of rice plants at or before the tillering stage [17].…”

Chinese milk vetch (Astragalus sinicus L., vetch), a leguminous winter cover crop, has been widely adopted by farmers in southern China to boost yield of the succeeding rice crop. However, the effects of vetch on rice grain yield and nitrogen (N) use efficiency have not yet been well studied in the intensive double-cropped rice cropping systems. To fill this gap, we conducted a three-year field experiment to evaluate the impacts of the vetch crop on yields and N use efficiency in the subsequent early and late rice seasons. With moderate N input (100 kg N ha−1 for each rice crop), vetch cover significantly increased grain yields by 7.3–13.4% for early rice, by 8.2–10.4% for late rice, and by 8.6–11.5% for total annual rice production when compared with winter fallow. When rice crops received an N input of 200 kg N ha−1, vetch cover increased grain yields by 5.9–18.4% for early rice, by 3.8–10.1% for late rice, and by 6.2–11.3% for annual rice production. Moreover, comparable grain yields (11.9 vs. 12.0 Mg ha−1 for annual rice production) were observed between vetch cover with moderate N and fallow with added N fertilizer. Yield components analysis indicated that the increased tillering number was the main factor for the enhanced grain yields by vetch cover. Vetch cover with moderate and higher N input resulted in higher agronomic N use efficiency and applied N recovery efficiency compared with the fallow treatments. Here, our results showed that vetch as a winter cover crop can be combined with reduced N fertilizer input while maintaining high grain yields, thus gaining a more sustainable rice production system.

“…In double-rice cropping systems, direct incorporation of CMV and/or RS into rice field is an important practice to dispose of residues and to improve soil physicochemical properties and increase crop yield. Proper management of crop residues introduces organic carbon into the soil, increasing the soil organic matter [10] as well as improving its physicochemical properties [11] , and maintaining rice production [12] . However, the incorporation of CMV and RS produces undesired consequences, such as GHG emissions.…”

Chinese milk vetch (CMV) and rice straw (RS) were incorporated into soil to substitute for synthetic N fertilizers and to maintain soil fertility. However, little is known about the integrated impacts of CMV and RS incorporation on CH 4 and N 2 O emissions in double-rice cropping systems in southern China. A field experiment was conducted to estimate the integrated impacts of CMV and RS incorporation in the early-and late-rice seasons on CH 4 and N 2 O emissions. All treatments received uniform N inputs, 6%-37% of which was replaced by CMV and RS crop residue. CMV and/or RS incorporation produced equivalent or slightly more grain yield, while reducing N 2 O emissions by 3%-43%. However, both CMV and RS incorporation increased CH 4 emissions. Annual CH 4 emissions ranged from 321 to 614 kg$hm-2 from CMV and RS amendment treatments, which were 1.5-2.9 times higher than that from synthetic N. Compared with single synthetic N fertilizer, incorporation of CMV and/or RS increased GWP and yield-scaled GWP by 45%-164% and 45%-153%, respectively. Our results demonstrate CMV and RS amendments replacing N fertilizer, maintained stable yield, mitigated N 2 O emission, but enhanced CH 4 emission. Further study is needed on crop residue management in double-cropping rice systems.

Harvesting cover crops for biofuel and livestock production: Another ecosystem service?

Harvesting cover crops (CCs) for livestock and biofuel production can be an important ecosystem service from CCs, but this potential service has not been widely discussed. We reviewed the potential use of CCs for livestock or biofuel production, impacts of CC harvesting on soils and crops, the amount of harvestable CC biomass, and strategies to enhance CC biomass production. We searched literature in Web of Science using terms such as “cover crops,” “harvesting,” “soil properties,” and “crop yield,” among others, and found about 30 papers. The literature indicates that CC harvesting does not generally affect soil properties, crop yields, and weed suppression, although the studies are relatively few. Leaving 7.5‐10 cm of CC stubble after harvest could maintain soil ecosystem services. Cover crops produce 3.37 ± 2.96 Mg ha−1 (mean ± SD) of aboveground biomass and 1.33 ± 0.98 Mg ha−1 of belowground (root) biomass. Root biomass input, representing about 30% of the total CC biomass production, could be critical to the maintenance of soil services after CC harvest. The amount of harvestable biomass while maintaining soil services ranges from 1‐3 Mg ha−1 in semiarid regions and from 1‐6 Mg ha−1 in humid regions for high‐biomass‐producing CCs. Strategies to increase CC biomass production include planting CCs early and terminating late, adapting cropping systems by using earlier‐maturity group varieties, and using flexible cropping systems. Overall, CC harvesting appears feasible, but additional research on CC management and harvesting effects on ecosystem services is needed before harvesting CCs at large scales.
