“…The cultivation of RRS under T5 produced on average 30.6% higher grain yield over that of T2 (Figure 4). These trends indicate an opportunity for NT with improved nutrient management in lowland rice cultivation with some yield advantage [3]. Similar grain yield of rice under puddled and minimum or unpuddled conditions have also been reported [3,62].…”

“…Enhancement of the TOC stocks of paddy soils can improve soil quality and has the potential to mitigate global warming. Moreover, a continuation of CT practice can enhance SOC and N mineralization by increasing oxidation of organic matter, disruption of soil aggregates, and increasing aeration, hence causing a reduction in SOC stocks [3,52]. Consequently, NT farming has been widely recommended as an alternative to CT for enhancing SOC sequestration in soils [3,18,[51][52][53][54].…”

Consequently, NT farming has been widely recommended as an alternative to CT for enhancing SOC sequestration in soils [3,18,[51][52][53][54]. Some studies have reported that NT practices can increase the SOC stock compared to CT in paddy agro-ecosystems [35,52] and the application of rice residues along with inorganic fertilizer could enhance SOC sequestration in the double-rice cropping system in some soils and ecoregions of India [55].…”

Over centuries and even today, traditional farming practices are well performed without any ecological degradation. However, management practice such as conservative tillage combined with nutrient and residue could increase the crop production as well as soil fertility. A three-year replicated study was conducted to assess the effects of agronomic modification of traditional farming practices on productivity and sustainability of rice (wet season)-rice (dry season) system (RRS). The replacement of farmers practice (T 2 ) with conservation effective tillage (no-till (NT)) and integrated nutrient management (INM) practice along with 30% residue retention (T 5 ) enhanced the straw, root and biomass yield of both wet season rice (WR), dry season rice (DR) and system as a whole over T 2 . Treatment T 5 recorded significantly lower soil bulk density ( b ) and higher pH than the T 2 after three years of the experiment. Further, treatment T 5 increased total soil organic carbon (2.8%), total soil organic carbon stock (2.8%), carbon sequestration rate (336.5 kg ha −1 year −1 ), cumulative carbon stock (142.9%) and carbon retention efficiency (141.0%) over T 2 of 0-20 cm depth after three year. The soil microbial biomass carbon concentration was significantly the highest under T 5 . Similarly, the dehydrogenase activity was the maximum under T 5 . Adoption of conservation tillage and nutrient management practice involving NT and INM along with residue retention can enhance the system productivity, and C and N sequestration in paddy soils is thereby contributing to the sustainability of the RRS.

“…In this anoxic soil environment, physical protection of SOM in soil aggregates is less effective in stabilizing SOM than in aerobic soils, possibly by the effect of water decreasing aggregate stability during the flooded rice growing season (Nascimento et al, 2009). Consequently, SOC is increased to a very small extent, if any, by the adoption of no-tillage in irrigated rice fields (Nascimento et al, 2009;Rosa et al, 2011;Ghimire et al, 2012;Das et al, 2014;Huang et al, 2016).…”

ABSTRACT:The DayCent ecosystem model, widely tested in upland agroecosystems, was recently updated to simulate waterlogged soils. We evaluated the new version in a paddy rice experiment in Southern Brazil. DayCent was used to simulate rice yield, soil organic carbon (SOC), and soil CH 4 fluxes. Model calibration was conducted with a multiple-year dataset from the conventional tillage treatment, followed by a validation phase with data from the no-tillage treatment. Model performance was assessed with statistics commonly used in modeling studies: root mean square error (RMSE), model efficiency (EF), and mean difference (M). In general, DayCent slightly underestimated rice yields under no-tillage (by 0.07 Mg ha -1 , or 9.2 %) and slightly overestimated soil C stocks, especially in the first years of the experiment. A comparison of observed and simulated CH 4 daily fluxes showed that DayCent could simulate the general patterns of soil CH 4 fluxes with slight discrepancies. Daily soil CH 4 fluxes were overestimated by 0.43 kg ha -1 day -1 (12 %). Growth-season CH 4 emissions under no-tillage were also somewhat overestimated (11 % or 45.29 kg ha -1). We conclude that DayCent simulated SOC, rice yield, and CH 4 with some inaccuracies, but the overall performance was considered adequate. However, the model failed to represent the observed potential of no-tillage to mitigate CH 4 emissions, possibly because model algorithms could not capture the actual field conditions derived from no-tillage management, such as soil redox potential, plant senescence, and surface placement of plant residue.

Ratoon rice is resource efficient to produce economically sound and environmentally sustainable rice production. However, there is no more information on the relative impact of soil tillage practices on soil physical and chemical properties, microbial biomass, and enzymatic activity, and grain yield in a rice–ratoon rice cropping system remains to be tested. Systematic study of soil under ratooning rice model is a problem to be solved in the development of ratooning rice model. This study primarily investigated the long‐term (from 2014 to 2020) changes in soil bulk density (BD), soil organic carbon (SOC) concentration, total nitrogen (TN) concentration, microbial biomass, β‐glucosidase activity (BG), urease activity (UR), and yield under four treatments: no‐tillage (NT), no plowing tillage + rotatory tillage (RT), plowing tillage in winter + rotatory tillage (PTW), and plowing tillage in spring + rotatory tillage (PTS). NT increased BD by 9.65%–12.97%, and RT increased the 20–40 cm soil layer BD by 8.80% in 2020, compared with the baseline initial value (in 2014). Plowing tillage (PT) time had no significant effect on BD. All tillage methods decreased the SOC concentration in the 0–20 cm soil layer, and only RT increased the TN concentration. PT was the only treatment that increased the SOC and TN concentrations in the 20–40 cm soil layer. Both the main‐season rice yield and the ratoon season rice yield ranked PTW > PTS > NT > RT, in which the main‐season rice yield increased by 28.15% and the ratoon season rice yield increased by 25.19% in PTW. Overall, the PTW treatment had the highest microbial biomass, enzyme activity, and grain yield compared with the other tillage methods. In conclusion, plowing tillage in winter + rotatory tillage is a more suitable tillage method under the mode of ratooning rice.
