“…The TN concentrations significantly decreased with the increase in the tillage frequency and intensity and followed the order of NT > RT > PT at 0-5 cm depth in both years [54]. Therefore, conservation tillage (NT/RT) based farming practices have been widely recommended for improving the TSN and N sequestration in soils [7,18,52,53,56]. However, C:N ratio has not been significantly affected by different treatments in the present study (Table 5).…”

“…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.

“…Relatively higher percentage increase of SOC stock was observed in F 4 with T 6 treatment (56.3Mg Cha -1 ) followed by F 6 with T 2 (51.4Mg Cha -1 ) and F 3 with T 1 (48.4Mg Cha -1 ). Xue et al, (2015) found that over time, CT system generally exhibit a significant decline in SOC concentration due to destruction of the soil structure, exposing SOM protected within soil aggregates to microbial organisms. Ghimire et al, (2012) revealed that 9.89% greater SOC in 0-50 cm soil profile under no-tillage than under conventional tillage in a rice-wheat system.…”

“…Increases in C concentrations, especially in surface soil, in response to ZT and residue mulch are known [44][45][46]. From a literature review, showed that in 40 of 78 cases, the SOC content was higher in ZT compared to CT; in 7 cases it was lower and in 31 of the cases there was no significant difference [47].…”

Resource conservation technologies (RCTs) such as zero tillage (ZT), dry direct seeded rice (DSR) and crop residues as mulch are known to increase productivity and profitability of rice-wheat system (RWS) in South Asia. There are, however, few studies on assessing the effect of RCTs on physical and chemical properties of soil under RWS.A field experiment on a sandy loam soil was conducted on RWS for two years at Modipuram, India involving six treatment combinations of three tillage and crop establishment methods in rice, (i) conventional puddled transplanted rice (CT-PTR), (ii) conventional dry tillage followed by direct seeding of rice (CT-DSR), and (iii) zero tillage followed by direct seeding of rice (ZT-DSR), and two green manuring options (with and without intercropping of Sesbania aculeata, -S or +S). In the succeeding wheat, rice residue (RR) was retained in sesbania green manure treatments and it was removed from no sesbania plots. Wheat was direct sown after ZT (DSW) in all the plots. Substituting PTR/ DSW without crop residues with ZT-DSR/DSW plus residue cycling reduced electrical conductivity from 0.146 dS m -1
