“…Under conservation tillage, residues accumulated on the surface and subsurface and slow decomposition of these due to reduced soil disturbance resulted in higher organic C and total N. Earlier work reported that SOC and N concentration increased by 7.7 g kg −1 and 197 kg-ha respectively, at 0 to 15 cm soil after continuous 4 years of rice-wheat rotation in north-west India [18,44,59]. Similarly, Małecka et al [60] found maximum SOC and total N 10,200 mg kg −1 and 1120 mg kg −1 at top (0 to 5 cm) soil of 7 years continuous no-till in Poland. Whereas, more organic carbon and nitrogen in wet tillage with crop residues incorporation of the rice scenario in comparison with that of other in the deeper soil profile (15 to 30 cm soil depth) was reported earlier [47,61].…”

In South Asia, soil health degradation is affecting the sustainability of the rice-wheat cropping system (RWCS). Indeed, for the sustainability of the soil quality, new adaptive technologies, i.e., conservation tillage and straw management resource conservation, are promising options. This investigation was focused on the interaction of tillage and straw management practices and their effects on Aridisols, Yermosols soil quality, and nutrients dynamics with different soil profiles within RWCS. The long-term field experiment was started in 2014 with the scenarios (i) conventional tillage (SC1), (ii) residue incorporation (SC2), (iii) straw management practices (SC3 and SC4) and conservation tillage (SC5). Conservation tillage practice (SC5) showed significant impact on properties of soil and availability of nutrients in comparison with that of conventional farmers practice (SC1) at the studied soil depths. The SC5 showed significant results of gravitational water contents (25.34%), moderate pH (7.4), soil organic-matter (7.6 g kg−1), total nitrogen (0.38 g kg−1), available phosphate (7.4 mg kg−1), available potassium (208 mg kg−1) compared to SC1 treatment at 0 to 15 cm soil depth. Whereas, DTPA-extractable-Cu, Mn, and Zn concentration were significantly higher, i.e., 1.12 mg kg−1, 2.14 mg kg−1, and 4.35 mg kg−1, respectively under SC5 than conventional farmer’s practices, while DTPA (diethylene triamine pentaacetic acid) extractable Fe (6.15 mg kg−1) was more in straw management practices (SC4) than conventional and conservation tillage. Therefore, conservation tillage (SC5) can surge the sustainability of the region by improving soil assets and nutrients accessibility and has the potential to minimize inorganic fertilizers input in the long run.

“…Climate change is threatening the agriculture, making farmers more vulnerable; posing challenges to sustaining productivity of farmers who constitute >50% population of country (Kumar et al 2021a). Considering that new approach is needed; development and deployment of technologies and capacity building have important role to play not only in building the farmer capability but also in changing the mindset (Kumar et al 2021b). Bihar is only state in the country that experiences drought and floods on a recurring basis.…”

There is an urgent need for identification of eco-friendly and cleaner production systems that are more productive, profitable, efficiently use energy/water/carbon input and are environmentally safer. Under that context, a long-term experiment was conducted during 2019–21 at the farmers’ fields of Krishi Vigyan Kendra (KVK), Gaya, Bihar. The main objective of the study was to evaluate the productivity of diverse cropping systems for irrigated and rainfed conditions. Nine cropping system, viz. transplanted puddled rice (TPR)–wheat (conventional-till)-fallow (farmers practices) [CS1],TPR-wheat(zero-till)-mung (ZT) [CS2], Conventional-till direct seeded rice (CTDSR)-mustard (ZT)-mung (ZT) [CS3], ZTDSR-lentil (ZT)-fallow [CS4], Maize (CT)-lentil (ZT)-mung (ZT) [CS5], Bajra (CT)- lentil (ZT)-mung (ZT) [CS6], Bajra (CT)-wheat (ZT)-mung (ZT) [CS7], TPR-chickpea (ZT)-fallow [CS8] and TPR-maize (CT)-fallow [CS9] were used for the present study. Maximum system productivity was recorded with maize (CT)-lentil (ZT)-mung (ZT) (13.2 t/ha), which was 46, 3.9, 13.8, 94.7, 22.2, 15.8, 39.5, 11.9% higher compared to CS1, CS2, CS3, CS4, CS6, CS7, CS8 and CS9, respectively. Net returns (`211677/ha) and Benefit cost (B:C) ratio (3.59) were recorded maximum with maize (CT)-lentil (ZT)-mung (ZT). Land use efficiency was the maximum with TPR-wheat (ZT)-mung (ZT) (92.6%). Carbohydrate equivalent yield was also maximum with TPR-wheat (ZT)-mung (ZT). Diversification of rice-wheat system with millets i.e. Bajra (CT)-lentil (ZT)-mung (ZT)/Bajra (CT)-wheat (ZT)- mung (ZT) improves the system productivity by 19.5–26.1% compared to TPR-wheat (CT)-fallow. Thus, the present study could be important to identify an alternate cropping systems for enhancing the overall system productivity and profitability sustainably through adoption of environment-friendly technologies.

“…However, we have not noticed any decrease in SOC content in the deeper soil layer. Differences in SOC stock under NT or CT can be linked to variable yield (Virto et al, 2012) and, therefore, net primary productivity, which decides the amount of organic matter inputs to the soil in the form of crop residue (Kumar et al, 2021). Under NT, the crop residue remains on the surface and is expected to influence the SOC concentration in the upper soil layers only, while the same likely to get incorporated to greater soil depth under CT and thereby alter the SOC balance of greater soil depth than NT (Meurer et al, 2018).…”

Deteriorating soil health, diminishing soil organic carbon (SOC), development of subsurface hard compact layer and declining system productivity are barriers to achieving sustainable production in the traditional rice-wheat cropping system (TA) in the eastern Indo-Gangetic Plain of India. Conservation agriculture (CA), which favours minimum soil disturbance, crop residue retention and crop diversification could be a viable alternative to the TA to address most of those major problems. With that in mind, a long-term experiment is being implemented at ICAR-RCER, Patna, Bihar, India, with four treatments: (a) TA, (b) full CA (fCA) and (c and d) partial CA (pCA1 and pCA2), differing in crop establishment methods, cropping system and crop residue management in a randomized complete block design. Measurement of soil health parameters was carried out in the 11th year of the experiment. The results revealed a beneficial effect of CA and 46 and 40% increase in SOC concentration and stock, respectively, under fCA over TA in the 0-7.5-cm soil layer. The effect of partial CA (pCA1 and pCA2) was variable, but an increasing trend was always observed under pCA compared to TA. There was an enrichment in SOC content of aggregates under CA irrespective of size class; however, no relation was found between SOC content and aggregate diameter. The contribution of macroaggregates to SOC stock was larger (36-66%) under CA in the 0-7.5-cm soil layer.Adoption of CA improved the macroaggregate content, MWD and GMD of aggregates, and aggregation ratio. Soil macropore content was greater under fCA, whereas other parameters were similar among treatments. The impact of CA was mostly limited to 0-7.5 cm soil layer and a maximum up to 15 cm soil depth while evaluation until 60 cm soil depth was realized. The yield of rice in
