The experiment factors were irrigation regimes including (i) full irrigation (well-watered), (ii) restricted irrigation from silicle formation (late-stress), (iii) restricted irrigation from flowering (mild-stress) and (IV) restricted irrigation from maximum stem length (early-stress) and planting dates consisting of (i) 27-Sep, (ii) 12-Oct and (iii) 25-Oct. The highest oil content (30.04%) was obtained from the first sowing date and was 2% and 5.4% higher than 12-Oct and 25-Oct, respectively. Obtained grains from well-watered irrigation regime had significantly more oil content (31.02%) than the other irrigation regimes. Delaying in sowing date and water-deficit stress raised saturated fatty acids (palmitic, stearic and arachidic acids). While delayed sowing date (12 and 25-Oct) and water-deficit stress (low, mild and severe stresses) increased the content of palmitic, eicosenoic and erucic fatty acids, the oleic, linoleic and linolenic acids were reduced in such conditions. It seems that postponing the sowing date to 12-Oct and restricting irrigation from silicle formation would be reasonable as it can decline water consumption.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2847 - 2861"},"PeriodicalIF":2.4,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45792602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Millsp.]. Arsenic reduced mycorrhizal symbiosis, nutrient availability and plant biomass by inducing oxidative stress. Si and AM inoculations decreased metalloid uptake and reactive species generation, with higher benefits under M2, followed by Si, then M1. Higher efficiency of M2 corresponded to its colonization ability and glomalin production as well as its capability of enhancing nutrient uptake by modulating soil enzymes (alkaline phosphate-ALP and arylsulfatase-aryl-S) activities. In addition, S metabolism and antioxidant system got up-regulated, leading to increased synthesis of thiol compounds and antioxidants in the order M2>Si>M1. Accumulated thiols further reduced As translocation by chelating and immobilizing metalloid in plant roots. Moreover, significantly higher As tolerance could be recorded when plants were supplemented with a combination of +Si+M2, indicating functional complementarity between the two amendments. The study, thus, demonstrated introduction of Si and AM in the rhizosphere as a promising strategy for inducing As tolerance to pigeonpea.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2814 - 2832"},"PeriodicalIF":2.4,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46493932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The closed chamber method was used to continuously monitor CO2 concentration in soil profiles of winter wheat-summer maize rotation fields in the North China Plain (NCP) during 2015–2017. Additionally, we evaluated the contribution of different tillage methods (Rotary tillage (RT), Subsoiling (SS), No- tillage (ZT), and conventional tillage (CT) in combination with Straw return (s) and straw removal (0)) to reducing soil CO2 emission. The results showed that the concentration of CO2 increased with the soil depth and peaked at the 150 cm layer. The trend of CO2 concentration in soil profiles under different tillage treatments was CTS > RTS > ZTS > SSS, and the average concentration in maize season was higher than that in wheat season. In addition, soil moisture and temperature in the 0–10 cm soil layer were significantly correlated with soil CO2 concentrations. Thus, our results highlight that the SSs plays a critical role in moderating soil CO2 emissions. This process merits further study to effectively regulate soil CO2 release and achieve carbon neutrality with less carbon emissions in farmland ecosystems.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2833 - 2846"},"PeriodicalIF":2.4,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49157524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of the analysis clearly explain the difficulty in the risk evaluation: i) difficulty in increasing exchangeable K, owing to retention as non-exchangeable K by vermiculite; ii) difficulty in retaining exchangeable K due to low K buffering capacity, reflecting the lack of K-selective clay minerals; and iii) difficulty in increasing soil solution K intensity due to high K buffering capacity, reflecting the abundance of K-selective clay minerals. Among the parameters calculated from the Q/I relationship analysis, β values, corresponding to the retention rate of loaded K to the soil, for total K (βt), exchangeable K (βe), and non-exchangeable K (βn) would be useful as simple indicators of soils with a predicament in the risk evaluation of radiocesium uptake by crops through exchangeable K.

Treatments consisted of three tillage methods: conventional tillage (CT) which involved the preparation of a flat seedbed using handhoe, annually constructed tied ridges (ATR) and tied ridges that had been constructed during the previous season and had been repaired (residual tied ridges–RTR). Data were collected on labour requirements and crop performance. RTR increased economic returns by 29% and 80% over ATR and CT, respectively. Maize grain yield shows a trend of RTR >ATR>CT with values ranging from 2465 kg ha−1 to 4185 kg ha−1 (P < 0.01). While tillage and/or variety did not influence sorghum grain yield significantly (P > 0.05). The use of RTR is recommended because of low labour requirements and greater economic benefits than CT and ATR under maize cropping systems.","PeriodicalId":8154,"journal":{"name":"Archives of Agronomy and Soil Science","volume":"69 1","pages":"2784 - 2797"},"PeriodicalIF":2.4,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49062928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with control treatment, the application of three biochars (at the rate of 3%) had significantly improved soil fertility, i.e. organic carbon, total nitrogen, available nitrogen and available phosphate, respectively. Biochar treatments significantly increased soil porosity, and aggregates stability, while reduced the soil salinity compared to the control treatment. Meanwhile, biochar application significantly increased the plastic index of coastal clayey soil while decreased soil tensile strength and shrink swell properties compared to the control. Biochar clearly altered soil pore characteristics, consequently rebuilding the new ions leaching channels. Overall, the cow manure biochar (650 °C) at the rate of 3% treatment showed maximum efficiency on soil salinity, fertility, physicomechanical properties, and crop yield.
