“…Our results suggest that T2 and T5 have a relatively positive effect on soil ρb. In contrast, other studies have reported higher ρb under NT at 0-5 cm depth compared to CT in cropping systems other than RRS [35,38,39]. Soil pH is an important soil quality factor affected by farmers practice and its modifications in the present study ( Figure 1B).…”

“…In a study in Bangladesh, minimum tillage unpuddled transplanting had no negative effect on rice yields across seasons and years, but reduced the time taken for land preparation and crop establishment and decreased the cost of production [9]. The negative effects of RT/NT on crop growth do not necessarily become concerns in wet-seeded flooded rice production systems [39]. The increase in rice yield in the present study may not only be due to tillage, but also due to the combined effect of conservation tillage, residue and nutrient management practices.…”

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.

“…Soil aeration is low in continuous rice cropping systems due to water logging. NT can further exacerbate the low soil aeration through increasing soil compaction and decreasing soil porosity (Huang et al, 2012b). As compared with continuous rice cropping systems, rice-upland rotations can lead to an increase in soil porosity within rice-growing season (Huang and Ding, 1995), which may to some extent offset the decreased soil porosity by NT.…”

“…The presence of crop residues over the soil surface prevents aggregate breakdown by direct raindrop impact as well as by rapid wetting and drying of soils. There are also reports showing slight or no differences in D b values between CT and ZT in the surface soil layers [58][59][60]. At 11-15-cm and 16-20-cm depths, D b was significantly higher in T1, T2, T3 and T4 than in ZT-DSR (T5 and T6).…”

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
