“…Using higher number of input and other field operation under conventional tillage practices, increases cost from the above treatments while less cost of cultivation under conservation tillage increases net monetary benefit. Adoption of no-tillage practice declined the cost of cultivation by 35% for directseeded upland rice over conventional tillage [50]. Similar findings (25-30% less cost of production) were also reported by Lal et al [4].…”

“…Low dry matter accumulations in zero tillage, possibly due to compact soils layer at plough depth in the initial years, and which might have adverse effect on root and plant growth [48,49]. In rice-maize system, maize yield was significantly reduced by 7.9% when no residue was applied to previous crop (rice), while yield was improved by 8.2% when residue applied @ 3 t/ha [50].…”

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.

“…In addition to optimized fertilization and agricultural mechanization, no-till technology with a straw return is also a good method for decreasing the CFs and WFs of crop production. This technology cannot only increase yield and reduce fertilizer use but can also increase soil water holding capacity, reduce soil evapotranspiration and nutrient loss, and increase soil organic carbon [50,51], which can alleviate carbon emissions and freshwater consumption and thus decrease CF and WF simultaneously.…”

Greenhouse gas (GHG) emissions and freshwater scarcity are central environmental concerns that are closely linked to crop production. The carbon footprint (CF) and water footprint (WF) of a crop can reflect the effects of crop production on GHG emissions and water use (WU), respectively. Studying the CFs and WFs associated with crop production will be conducive to understanding the environmental changes caused by agricultural activities, and exploring the relationship between CFs and WFs can provide a basis for strategies that reduce environmental pressures. We estimated the CF and WF of maize production in Jilin Province from 2004 to 2017 and analyzed their spatiotemporal characteristics. The results showed that the average CF and WF were 0.177 kg CO2eq/kg and 0.806 m3/kg from 2004 to 2017, respectively; 69% of the GHG emissions were due to the manufacture; transportation and application of fertilizer; and 84% of the water use was attributed to the green WF. The relationship between the CF and WF of maize production was significantly positive and indicated the possibility of simultaneous mitigation. Potential practices such as the optimization of fertilization and of agricultural machinery use and the incorporation of no-till technologies with the straw return are recommended to mitigate both GHG emissions and water use and achieve triple-win agriculture with low carbon use and water and energy savings

“…Agricultural waste can be used for many economic purposes but the cost involved in its collection, processing, and transportation is much higher than the economic returns. 16,[28][29][30] Annualy, global agricultural production systems generates about 4.6 billion tonnes of utilizable agri-residue. 17,31 About 500 Tg crop residues are generated by Indian agriculture every year, out of which more than 25% are burnt on the farm.…”
