“…These results are in line with results from an earlier study in which the shoot biomass of narrowleaf vetch and tiny vetch grown under P-non-limiting conditions over a long growing period in a subtropical region ranged from 42-62% and 12-25%, respectively, of the value of hairy vetch (Anugroho and Kitou 2007). Even though Chinese milk vetch is widely used as a cover fertilizer crop in rice fields in temperate regions (Samarajeewa et al 2005), it did not grow well under the subtropical conditions of the present study.…”

Soil acidity is one of the most serious causes of land degradation and limits crop production in subtropical agriculture. A number of legumes have adapted to P‐limiting conditions, and the aim of the present study was to select an appropriate species for use as a winter legume cover crop under subtropical soil conditions in Okinawa, where P deficiency stems from soil acidification. Four vetch and four clover species were examined in pot trials. Of these, hairy vetch (Vicia villosa Roth) was found to be the most tolerant of P‐limiting conditions. The shoot biomass of hairy vetch was also generally higher than that in the clover species when the P supply was non‐limiting in the spring season. Hairy vetch was then compared in a pot trial with four clover species for an extended period of growth with adequate P supply. The N fixing activity of hairy vetch in the vegetative stage was 3.2‐fold greater than that of the clover species. Nitrogen and P uptake in shoots and roots was significantly higher in hairy vetch than in the clover species in the vegetative and flowering stages. The C/N ratio in the shoots and roots of hairy vetch tended to be lower than that in the clover species. Shoot K uptake by hairy vetch was significantly higher in the vegetative stage than that in the clover species. In a field trial, shoot biomass and nutrient uptake of hairy vetch were similar on four different subtropical soils with pH values ranging from 5.7 to 7.5. Hairy vetch is an appropriate winter legume cover crop to improve subtropical soils by increasing organic matter and supplying nutrients to the subsequent crop.

“…Chinese milk vetch is a viable option for a sustainable winter cover crop because it improves both soil fertility and crop yield (Samarajeewa et al, 2005). Chinese milk vetch can also increase soil pH (Zhang et al, 2017), although this effect was not observed in our study.…”

Background Chinese milk vetch (Astragalus sinicus L.) can improve paddy soil fertility and ecology through nitrogen fixation, but it can also increase greenhouse gas emissions. Our primary objective was to investigate how Chinese milk vetch, rice straw, and nitrogen fertilization affect the methane and microbial components of the rice rhizosphere. Methods We examined the rhizosphere’s methane emissions and microbial abundance and diversity after incorporating Chinese milk vetch and rice straw into paddy soil. We used high-throughput sequencing of the 16s rRNA and ITS1 genes to study changes in the bacterial and fungal communities, respectively. Over the course of our experiment, we applied seven different treatments to the paddy soil: conventional fertilization (the control treatment) for winter fallow crops, three levels of nitrogen in Chinese milk vetch, and three levels of nitrogen in Chinese milk vetch combined with rice straw. Results Rice yield and methane emissions increased during cultivation when the soil was treated with Chinese milk vetch with and without added straw. The nitrogen application also affected the methane fluxes. Alpha diversity measurements showed that Chinese milk vetch increased the diversity of the soil fungal community but did not significantly affect the bacterial community. Chinese milk vetch affected the rhizosphere microorganism communities by increasing the number of Methanomicrobia.

“…These enzymes could be change the soil biological modi cation (Caravaca et al 2002). Chinese milk vetch winter legume have been broadly used for crop rotation mostly in rice eld at southern parts of china (Samarajeewa et al, 2015). Recently, the cultivation of green manure crops has become a common practice to increase soil fertility in south china earlier; wide attentions have been given to N utilization in green manure species.…”

Winter green manure potentially uptake large amount of phosphorus (P) and potassium (K) from the soil. However, the mechanism underlying nutrient uptake in green manure varieties remain elusive. This study illustrates the P and K uptake potential in different leguminous and non-leguminous species through integrated approaches. The designed studies evaluated the 10 green manure crops included five leguminous species (i.e smooth vetch hairy vetch, common vetch, lathyrus sativus, and milk vetch) and five non-leguminous species (i.e February orchid, chinese radish, forage radish, rapeseed and ryegrass) were planted. Experimental results indicated that the smooth vetch had highest P and K uptake capabilities among all leguminous species. While, rapeseed and chinese radish greatly P and K obtain among all non-leguminous treatments. Therefore various species also affected soil P and K availability and soil enzymes. Soil enzymatic activities including phosphatase (150.7%) and N-acetyl-glucosaminidase (95.4%) were elevated in lathryus sativus compared to the hairy vetch and common vetch respectively. The highest β-glucosidase (95.2%) and leucine-aminopeptidase (107.6%) activities accumulated in lathyrus sativus greater than the smooth vetch in all legumes species. In non-leguminous treatments phosphatase (500.5%), β-glucosidase (424.4%), and N-acetylglucosaminidase (256.3%) activities were improved in chinese radish as compared to the rapeseed. In constrast ryegrass was promoted greatest leucine-aminopeptidase activity by 182.7% higher than forage radish. However soil enzymes significanlty improve soil nutrient status. As a conclusion smooth vetch, rapeseed, and Chinese radish varieties have more P and K obtain capacity and forage radish could enhance soil enzyme activities. It is suggested these varieties might be a better choice in green manuring practice for improving nutrient management and soil nutrient quality in agro-ecosystems.
