“…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]. Moreover, ZT promotes nutrient retention by reducing leaching through the physical barrier created by crop residues, improving nutrient availability, mainly N, P, and K, for plant uptake [90,91]. Additionally, the undisturbed soil structure and increased OC content in ZT soil foster a diverse and active microbial community that plays a vital role in nutrient cycling and mineralization [92], converting SOM into plant-available forms ( [93].…”

“…While ZT offers long-term soil conservation benefits [112], careful consideration of these cost factors is essential for farmers. CT systems exhibit higher yield potential due to favorable seedbed preparation, which promotes better seed germination and reduces weed competition [91]. Effective weed control and pest management in conventionally tilled systems contribute to improved crop growth and yield, minimizing yield losses [107].…”

“…Additionally, the gross returns in IWM are higher, while the net returns and B:C ratio are higher in W1 [116] due to the higher cultivation costs. With appropriate locationspecific optimization of the available techniques, IWM can be recommended with regard to environmental aspects and issues such as herbicide resistance and weed shift [91,117].…”

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.

“…Direct seeding of rice accelerates establishment and early harvesting compared to transplanted rice, thus enabling timely wheat seeding [5] thereby promoting the sustainability of both rice and wheat in the rice-wheat cropping system [6]. With the introduction of resource-conserving technologies, direct seeding is emerging as a feasible alternative to transplanted rice [7]. Concerns about water scarcity are being addressed by the growing use of direct-seeded rice (DSR), which is a more economical and sustainable option.…”

Aim: The aim of the experiment was to check the effect of establishment techniques and weed management strategies on chemical properties of soil. Study Design: The design of the experiment was split plot design. Place and Duration of Study: Assam Agricultural University-Assam Rice Research Institute, Titabar, Assam, India, during the sali season of 2022-2023. Methodology: A total of three establishment techniques viz., broadcasting , drum seeding and line sowing in main plot and six different weed management practices namely hand weeding at 20, 40 and 60 DAS , pyrazosulfuron-ethyl @ 30 g/ha at 2 DAS fb bispyribac-Na @ 25 g/ha at 25 DAS, pyrazosulfuron-ethyl @ 30 g/ha at 2 DAS fb mechanical weeding at 40 and 60 DAS, pyrazosulfuron-ethyl @ 30 g/ha at 2 DAS fb bispyribac-Na @ 25 g/ha at 25 and 45 DAS , weed free check and weedy check in sub plot , respectively. Where DAS=Days after sowing and fb=followed by. Results: Results revealed that among various establishment techniques, drum seeding technique resulted in the lowest available nitrogen (237.87 kg/ha), phosphorus (21.67 kg/ha) and potassium (150.15 kg/ha) in the soil, respectively after harvest. Moreover, under various weed management practices, pyrazosulfuron-ethyl @ 30g/ha at 2 DAS fb bispyribac-Na @ 25 g/ha at 25 and 45 DAS showed lowest nitrogen (236.87 kg/ha), phosphorus (21.37 kg/ha) and potassium (149.23 kg/ha) in the soil, respectively after harvest which was next to weed free check. Conclusion: Combined application of drum seeding along with pyrazosulfuron-ethyl @ 30g/ha at 2 DAS fb bispyribac-Na @ 25 g/ha at 25 and 45 DAS can facilitate optimum plant population of crop with dense canopy cover, resulting in higher uptake of essential minerals and nutrients by the crop, enhancing the overall yield of rice while minimizing weed population throughout the growing period.
