“…The adoption of DSR by paradigm shifting from conventional tillage led to a significant decrease in the carbon footprint of RWCS [33]. The direct N 2 O emission from the soil was 25-29% under conservation agriculture-based RWCS [34]. Similarly, SSNM had a marked influence on the estimated nitrous oxide (N 2 O) emission during both years of the experiment, as suggested by our study.…”

Conventional tillage practices coupled with irrational use of fertilizer in the rice-wheat cropping system (RWCS) often leads to poor productivity, low nutrient use efficiency, and cause environmental pollution. Conservation tillage with surface residue retention in combination with intelligent nutrient management might improve productivity and use efficiency of water as well as nutrients in zero-till direct-seeded rice (ZTDSR). Keeping this in mind, during the kharif season of 2018 and 2019, a trial was carried out at the ICAR-IARI in New Delhi to investigate the varying nutrient management approaches following a precise manner in DSR. The treatments consisted of soil-test-based NPK (STB-NPK) and Nutrient Expert® (+LCCN) based NPK (NE-NPK) applications, Fertilizer applied at the recommended dose (RDF) [120-60-40 kg/ha NPK], the state recommended NPK (110-50-40 kg/ha) and omission plot technique of NPK [i.e., STB (N0PK, NP0K & NPK0); SR (N0PK, NP0K & NPK0) and NE-(N0PK, NP0K & NPK0)]. The results indicated that STB NPK application led to a 12% higher grain yield over RDF. However, NE-NPK resulted in a 7% and 35% increase in N (AEN) agronomic efficiency and P (AEP) over the STB-NPK application respectively. In contrast, AEk was 24% higher in STB-NPK over NE-NPK treatment. The comparison of two years’ results that the first year performed better than the succeeding year in these respect (productivity and AE) except in the case of AEk. The N2O emission in NE-NPK treatment was also significantly reduced (49%) over the control (no N). STB-NPK treatment also improved profitability by 22% over RDF. Precision nutrient management (PNM) increased the crop yield, income, and use efficiency of nutrients and water and reduced greenhouse gas (GHG) emissions of DSR in Southeast Asia.

“…Factors such as soil health, water usage, GHG emissions, and long-term sustainability should be evaluated to make more comprehensive conclusions about the benefits and trade-offs of different tillage methods. Taking those into account, MT emerges as the superior tillage approach since it maintains soil health, is cost-effective, and yields outcomes on par with those of CT practices in the short term while after stabilization ZT can potentially improve the system's performance [ 26 , 39 ]. This experiment showed that live mulching had the highest net energy and energy output.…”

“…Reduced soil erosion, improved water infiltration and retention, higher SOC content, and improved soil structure are just a few potential advantages that these techniques can provide in the long run [ [19] , [20] , [21] , [22] , [23] ]. Additionally, conservation tillage techniques have the potential to maintain soil fertility, soil productivity, decrease labour requirements, increase profitability, energy efficiency, and reduce greenhouse gas (GHG) emissions [ [24] , [25] , [26] , [27] ].…”

“…The maximum upsurge in SOC content (0.59%) from the initial value was observed in T 5 , where the ZT practices offer several interlinked reasons for higher OC content and increased nutrient availability in comparison to CT soil. Firstly, ZT minimizes soil disturbance, preserving soil organic matter (SOM) and preventing its oxidation, resulting in higher OC levels [86,87]. The presence of crop residues on the soil surface in ZT systems further contributes to OC accumulation by providing continuous organic material that gradually decomposes, which enhances the SOC content and positively influences soil health and nutrient availability [88,89].…”

A three-year field experiment was carried out to assess the efficacy of various tillage and residue management practices, as well as weed management approaches, in a rice–wheat–green gram rotation. The treatments included: conventional till transplanted rice–conventional till wheat–fallow (T1); conventional till transplanted rice–zero-till wheat–zero-till green gram (T2); conventional till direct-seeded rice—conventional-till wheat—zero-till green gram (T3); zero-till direct-seeded rice—zero-till wheat—zero-till green gram (T4); zero-till direct-seeded rice + residue zero-till wheat + residue zero-till green gram (T5). In weed management, three treatments are as follows: recommended herbicides (W1); integrated weed management (W2); and unweeded (W3). The integrated weed management treatment had the lowest weed biomass, which was 44.3, 45.3, and 33.7% lower than the treatment W3 at 30 and 60 days after sowing and harvest, respectively. T1 grain and straw yielded more than T2 in the early years than in subsequent years. The conventional till transplanted rice–zero-till wheat–zero-till green gram system produced 33.6, 37.6, and 27.7% greater net returns than the zero-till direct-seeded rice—zero-till wheat—zero-till greengram system, respectively. Conventional till transplanted rice–conventional till wheat–fallow had the biggest reduction (0.41%) in soil organic carbon from the initial value. The findings of the study demonstrated that adopting the transplanting method for rice, followed by zero tillage for wheat and green gram, enhanced productivity and profitability, while simultaneously preserving soil health.
