“…In the relatively short time of 2.5 years (after Crop 7), the SP and HR practice resulted in increased SOC concentrations at 0-0.15 m soil depth when compared to current practice involving intensive tillage along with 2021) reported significant increases in SOC after three years under SP (24%) and zero tillage (23%) as compared to CT at 0-0.05 m soil depth in the rice-lentil/wheat-jute systems of Bangladesh. Likewise, Saurabh et al (2021) reported a 18% increase in SOC at 0-0.1 m soil depth under zerotill direct seeded rice followed by zero-till wheat as compared to puddled transplanted rice followed by conventional wheat after four years in a rice-wheat system of Eastern Indo-Gangetic Plain. Increases in SOC pools with CA after four years in a rice-wheat cropping system of Northwest India were also reported by Jat et al (2019).…”

Studies of rice‐based systems in the Indo‐Gangetic Plain (IGP) have demonstrated the beneficial effects of Conservation Agriculture on soil organic carbon (SOC) status, along with increased soil health and crop productivity. However, it remains unclear as to the time for such treatments to have a positive effect. In this study of lentil‐mung bean‐rice and wheat‐mung‐rice rotations in Bangladesh positive effects of strip planting or bed planting, along with residue return, on SOC pools were apparent after 1.5 years, compared with intensive conventional tillage and limited residue return. Conventional tillage resulted in higher CO2 emission compared with strip planting or bed planting as did high residue return. In the cereal‐dominated rotation, the strip planting system sequestered carbon at a rate of 0.24–0.53 Mg C ha−1 year−1 (at 0–0.15 m depth) while conventional tillage was associated with a carbon loss of 0.52–0.82 Mg C ha−1 year−1. In the legume‐dominated rotation, neither practice sequestered SOC. Under strip planting, a minimum annual crop residue input of 1.7 Mg C ha−1 for the cereal‐dominated system and 5.2 Mg C ha−1 for the legume‐dominated system was required to maintain SOC at equilibrium. We conclude that strip planting with high levels of crop residue return can be an effective and quick strategy in either slowing the loss of SOC or improving C sequestration in the intensive rice‐based systems of the Eastern IGP.

“…The second set of experiments based on diversified CA cropping systems was established in 2015, where an experiment comprising seven tillage and crop establishment (TCE) methods for a rice–wheat-mungbean system was established in a randomized complete block design (RCBD) with three replications. Briefly, seven treatments in different management practices were divided as follows: Sc1) random puddled transplanted rice (RPTR)-conventional tilled (CT) broadcast wheat (BCW)-zero-till mungbean (ZTM); Sc2) line puddled transplanted rice (LPTR)-CT drilled wheat (CTW)-ZTM; Sc3) conventional tilled machine transplanted rice (CTMTR)-zero-till wheat (ZTW)-ZTM; Sc4) zero-till machine transplanted rice (ZTMTR)-ZTW-ZTM; Sc5) system of rice intensification (SRI)-system of wheat intensification (SWI)-ZTM; Sc6) CT direct-seeded rice (CTDSR)-ZTW-ZTM; Sc7) zero-till DSR (ZTDSR)-ZTW-ZTM 15 , 20 (Supplementary Table 2 ). The third set of CA experiments was established in the rainy season of 2016 to address the rice-fallow production system, where rice-chickpea, rice-lentil, rice-safflower, rice-linseed, and rice-mustard sequences were followed under diverse tillage production systems (ZTDSR, CTDSR and TPR with and without residue management practice 27 (Supplementary Table 3 ).…”

Conservation agriculture (CA), which encompasses minimum soil disturbance, residue retention either through crop residue, or cover crops and crop diversification-based crop management practices can modify the status of pest dynamics and activities under the changing climatic scenarios. CA has been advocated extensively to optimize the use of available resources, maintain the environmental quality, enhance crop productivity, and reduce the climate change impacts. Information related to the impacts of long-term CA-production systems under rice-based cropping systems on pest status is lacking, particularly in middle Indo-Gangetic Plains (MIGP). Under CA, puddling is completely avoided, and rice is directly sown or transplanted to maintain better soil health. Different sets of experimentations including farmers practice, partial CA and full CA (CA) as treatments in rice-based cropping systems, were established from 2009, 2015 and 2016 to understand the long-term impacts of CA on pest dynamics. In this study, direct and indirect effects of tillage (zero, reduced and conventional tillage), residue retention and cropping sequences on abundance and damage by pests were investigated. After 4–5 years of experimentation, populations of oriental armyworm [Mythinma (Leucania) (Pseudaletia) separata (Wlk.)] in wheat, mealybug [Brevennia rehi (Lindinger)] and bandicoot rat [Bandicota bengalensis (Gray)] in rice were found to increase abnormally in CA-based production systems. Conventionally tilled plots had a significant negative effect while residue load in zero-tilled plots had a significant positive effect on larval population build-up of M. separata. Zero tillage had a higher infestation of mealybug (52–91% infested hills) that used grassy weeds (Echinochloa colona, Echinochloa crusgalli, Cynodon dactylon, Leptochloa chinensis and Panicum repense) as alternate hosts. Cropping sequences and no disturbance of soil and grassy weeds had higher live burrow counts (4.2 and 13.7 burrows as compared to 1.47 and 7.53 burrows per 62.5 m2 during 2019–2020 and 2020–2021, respectively) and damaged tillers (3.4%) in CA-based practices. Based on the present study, pest management strategies in CA need to be revisited with respect to tillage, residue retention on soil surface, grassy weeds in field and cropping sequences to deliver the full benefits of CA in MIGP to achieve the sustainable development goals under the climate change scenarios.

“…But the continuous adoption of this system has resulted in several negative effects on soil health (Nandan et al, 2021). Repeated puddling in coarse and medium-textured soils has resulted in subsurface compaction, which affects the cultivation of successive upland crops, such as wheat, by restricting the root growth and causing aeration problems (Hossain et al, 2021;Saurabh et al, 2021). Puddled transplanted rice, when following a wheat crop, exposes the hidden organic matter to air and results in its oxidation, thus leading to structural degradation of the soil.…”

The rice–wheat cropping system (RWCS) is the backbone of Indian farming, especially in the north-western region. But continuous adoption of the RWCS in northwest India has resulted in major challenges and stagnation in the productivity of this system. Additionally, the Indo-Gangetic Plains of Pakistan, Nepal, and Bangladesh are also facing similar challenges for sustainable production of the RWCS. Several emerging problems, such as the exhausting nutrient pool in soil, deteriorating soil health, groundwater depletion, escalating production cost, labor scarcity, environmental pollution due to crop residue burning and enhanced greenhouse gas emissions, climatic vulnerabilities, and herbicide resistance in weed species, are a few major threats to its sustainability. To address these challenges, a wide range of sustainable intensification technologies have been developed to reduce the irrigation and labor requirements, tillage intensity, and straw burning. Awareness and capacity building of the stakeholders and policy matching/advocacy need to be prioritized to adopt time- and need-based strategies at the ground level to combat these challenges. This review summarizes the current status and challenges of the RWCS in the northwest region of the country and also focuses on the precision management options for achieving high productivity, profitability, and sustainability.
