“…Among the crops under study, the energy required by rice was higher followed by wheat, while greengram used the lowest energy ( Table 7 ). The highest energy consumption by rice mainly attributed to high fertilizer use, tillage practices and labour ( Babu et al, 2020 ). The DSR-based cropping system had a significantly (P < 0.05) lower energy requirement compared to PTR-based system.…”

“…The total input energy in greengram (7.22 GJ ha −1 ) was similar in all the treatments. Reduced energy requirement in rice and wheat under zero-tillage was mainly due to less input in terms of labour, diesel used for tillage and water irrigation ( Babu et al, 2020 ; Mitra et al, 2018 ). The energy output in rice, wheat and greengram under different treatments ranged from 142.87–180.31, 116.89–143.90 and 28.81–36.60 GJ ha -1 , respectively.…”

“…In other reports, the GHG emissions of crops in Germany ranged from 452 to 3505 kg CO 2 eq/ha [50]. Babu et al [51] reported that GHG emissions of crops in India varied from 1250 to 2120 kg CO 2 eq/ha. However, the GHG emissions in our study were far higher than those in other countries [52].…”

Ensuring national food security amidst ongoing economic development whilst both protecting the environment and reducing the dependence on fossil fuels are significant challenges for Chinese sustainable development. The main objectives of this study were to reveal irrigated crop (wheat, maize, and sunflower) performance in terms of energy, economic, and environmental aspects in China’s largest designed irrigation area, Hetao irrigation district (HID), and to evaluate agricultural suitability based on plant structure. An integrated indicator and comprehensively assessment method were used to evaluate the above objectives based on the results from in-person surveys. The results show that maize exhibits the best overall performance compared to two other major crops (wheat and sunflower), which supports the government policy of adjust and optimize the planting structure program (AOPST), an effective way to achieve the multiple-objectives for sustainable agricultural development. However, reducing fertilizer remains a more critical factor than AOPST. These study results provide useful guidance for policy-makers and relevant stake-holders both in a regional context for the HID and at the global agricultural governance and management level.

“…In agriculture, environmental sustainability implies good stewardship of the input resources and natural systems (Tittonell, 2014;Sabiha et al, 2016). Achieving economic sustainability in agriculture production remains an overwhelming challenge to researchers, policymakers, development partners, and national governments around the globe (Babu et al, 2020). In the current era, the conventional agriculture system has a major concern associated with the extensive use of external inputs including seeds, land management practices, agrochemicals (fertilizers, pesticides & herbicides) and water, which is negatively influencing farmers' profit and yield (Cristache et al, 2018,).…”

Better management practices (BMPs) as a sustainable approach made it attractive for growers to control the provision of pollutants from agricultural activities as well as enhance the financial return. The experiments of cotton production were conducted in four different regions of Punjab in cotton-growing years 2017-2019. The objective of the study was to evaluate the potential impact of BMPs among cotton farmers by rationalizing the use of input resources (viz., seed, fertilizers, pesticides and water). The data were collected from randomly selected adopters of BMPs (n = 400) and non-adopters of BMPs (n = 100) through a well-structured pretested questionnaire using a multistage sampling procedure from four different regions of Punjab province. Descriptive analysis was employing an independent two-sample t-test to evaluate the significant effect of BMPs on the utilization of input resources and profitability of cotton production between adopters and non-adopters of BMPs. The results indicated that adopters of BMPs were efficiently used input resources (at p ≤ 0.001 & p ≤ 0.01) and significantly enhanced the average cotton yield (855.09 kg acre-1) in Punjab, while non-adopters of BMPs had a significantly high cost of production by 11% (35,655 PKR acre-1) and output was lower by 15% (751.70 kg acre-1) under conventional farming for cotton cultivation. The economic analysis revealed that the average gross income gained by adopters of BMPs was significantly high by 11% (72,648 PKR acre-1 at p ≤ 0.001) with the maximum net return of 36% (40,785 PKR acre-1 at p ≤ 0.001) as well as a good B:C (1.28) as compared to non-adopters of BMPs. This study provides useful information about the potential impact of BMPs among cotton farmers even without the extra use of inputs. It is concluded that precision in inputs and management practices with lower input costs can significantly improve cotton productivity leading to uplift the farmers’ profit.
