“…Surface residue retention in zero-tillage suppresses weed emergence to a certain extent, residues also restrict manual or mechanical weed control [36]. The experimental results were also corroborated with the findings of Chaudhari et al [37], reported highest dry biomass of total weeds under zero tillage followed by zero tillage + residue treatment.…”

“…Schwab et al [40] indicated that conventional tillage eliminated compaction of sub-surface soil due to deep tillage, which may have enhanced root growth and subsequent nutrient and water uptake thereby produced higher seed yield. Getting of higher yield is also result of effective weed control that enhanced yield attributes and thereby yield [37].…”

Tillage and crop residue management play an imperative role in soil physico-chemical properties that eventually affects crop productivity. The objective of the study to find out a compatible combination of tillage and crop residue management for achieving sustainable food production by improving soil properties, providing favorable environment to crop plants. Secondly, managing crop residues effectively to reduce environmental pollution arising due to crop residue burning. With this aim, a field experiment was conducted on six years continued running experiment under conservation agricultural practices during rabi season of 2019–20 on chickpea. The experiment was comprised of five tillage operations with or without crop residue in main plot and three levels of nutrients in sub plots laid out in split plot design with three replications. Reduced Tillage with 60cm residue height (RT60) was recorded higher growth and yield attributes over conventional tillage practice that attributed to economic yield enhancement. The percent yield increment under NT and RT with 30 and 60cm height residue retention varied from 6.91% to 9.67% over conventional tillage. Maximum grain (2380 kg ha-1) and biological output (5762 kg ha-1) was recorded under RT60 (T4), which ascribed to higher net return (Rs 60551 ha-1) and benefit-cost ratio (2.97). The augmentation in net monetary benefit among tillage systems was lies between 24.32% to 37.78% over conventional tillage. The seed protein content ranged between 20.38 to 21.69% among the treatments. Moreover, total N uptake was maximum under RT60, while total P and K uptake was higher in No Tillage with 30cm residue height (T1). No-Tillage with 60cm residue height (NT60) recorded relatively higher soil moisture content (SMC) (22.71 and 15.40%). Treatment NT30 accrued relatively higher value of soil bulk density (1.42 Mg m-3) followed by NT60 and RT60 in comparison to conventional tillage (1.34 Mg m-3). In conclusion, NT and RT with 60cm residue height along with STCR (N3) nutrient dose was found effective for sustainable food production.

“…Additionally, the availability of energy and nutrient resources and the limited oxidation of soil organic carbon, favored by the prevalence of soil microorganisms, likely contributed to this observed enhancement. These results of this present investigation, are supported by Chaudhari et al [50] who observed that the combination of zero tillage + residue retention and inter-cultivation (IC) + hand weeding (HW) as the most suitable strategy for sustenance of greatest soil microbial biomass.…”

In a diversified cropping system, the kinds of tillage methods and weed management practices significantly influence soil microbiome, which affects crop productivity. The synergetic impacts of such practices on soil microbiome in association with yield under diverse crop rotation with conservation agriculture (CA) have not been extensively explored thus far in Southern India. Thus, a CA experiment was undertaken to investigate the impact of tillage and weed management on soil microbiome and fungal diversity at 30 days after sowing (DAS) and tasseling stage (60 DAS) of maize (in the 8th crop cycle) and to monitor yield. Three tillage practices; T1:CT(C)-CT(M)-fallow(NSr), T2:CT(C)-ZT(M)-ZT(Sr) and T3:ZT(C) + SrR-ZT(M) + CR-ZT(Sr) + MS and weed control tactics involved; W1-Chemical weed control, W2-Herbicide rotation (in alternative year), W3- Integrated weed management (IWM) and W4-Single hand-weeded control were laid-out in split-plot design. Rhizosphere soil and rhizoplane samples were collected from the respective plots at 30 DAS after herbicides application and tasseling stage (60 DAS). Analysis for microbial population and fungal diversity, enzyme and microbial activities was done duly following standard procedures. The salient findings indicated; a decline in enzyme activities, microbial population, microbial activities at initial stages (30 DAS) due to impact of herbicides which later on increased by tasseling. These biological properties were higher under T3 and W4, followed by IWM except metabolic quotient (qCO2) which showed a decreasing trend relative to T1, T2 and W1, W2 at both sampling stages of maize. Kernel yield (KY) and System yield (SY) were enhanced by T3 and IWM, herbicides treated plots (W1 and W2) compared to T1, T2 and W4. Talaromyces flavus, a beneficially rhizosphere micro-inhabitant was identified under T3 in combination with IWM. Considering both crop productivity and soil biological assessment, T3 and IWM were considered the best treatment combinations among all others with SY (4453 kg ha− 1). These findings signify the importance of adopting reduced tillage (T3) and IWM to achieve sustainable biodiversity and food security. This will further help the farmers and the policy makers to deeply understand the effectiveness of developing sustainable and eco-friendly tillage practice and weed control strategy for improving soil health and bolstering sustained crop productivity.
