“…This could prove to be advantageous for the IGP, where farmlands are facing acute water shortages, and the lowering of the water table in some of the RW areas as a repercussion of extreme groundwater pumping [12,18,33]. Progress in crop water productivity (CWP) holds the promise of food security, as well as water sustainability in RW cropping systems of the IGP [13,34,50,52]. Crop establishment technologies, with an emphasis on resource conservation, are normally reported to preserve 20-35% of irrigation water in the wheat against conventional practices [9].…”

“…Third, SS of wheat does not necessarily entail the retention of crop debris as mulch. The viability of the rice-wheat cropping systems (RWCS) is threatened as a result of challenges posed by phreatic water depletion, plummeting economic returns, and productivity stagnation in south Asia [12,13]. Promoting SS-based management practices, especially the use of improved seeds, optimum fertilization, integrated soil-and cropmanagement, besides increased investment in agricultural R&D, is the key to a sustainable production system [14].…”

“…SS can also capture revenue synergies among prevailing management activities for rural development and sustainable agriculture, which would substantively contribute to attaining the Sustainable Development Goals (SDGs) (Figure 2). Nutrient transformation/mineralization in soil depends on the biological and physicochemical characteristics, and, by adopting SS, all these traits improve significantly, enhancing crop productivity in return [4,13]. In the light of the increasing popularity of SS among the farmers of the eastern IGP as a resource conservation technology, we compiled this review paper covering the concept of the SS of wheat, environmental impact of its adoption, and the potentials and constraints of SS-based technologies in the IGP of India.…”

Conventional tillage (CT)-based agriculture is known to be ecologically indiscreet, economically and environmentally unsustainable, and leads to the degradation of soil andtheenvironment in the Indo-Gangetic Plain (IGP). The surface seeding (SS) method was introduced to manage agro-ecosystems for sustaining productivity and increasing farmers’ profits, while sustaining the natural resources. Here, we conducted a systematic literature review on SS of wheat reported in the IGP, with the aim to cover the concept of SS, its impact on wheat yield, soil properties, andtheenvironment, withthepotential benefits and constraints. The major findings are: (i) an SS-based rice–wheat system improves productivity (∼10%) and profitability (20–30%),whileemploying a lesser amount of irrigation water (15–30%) and energy input (20–25%) compared to a conventional system; (ii) an SS-based system is more adaptive to extreme climatic conditions, reducesthecarbon footprint, and increases crop production; (iii) an SS approach enhances soil health by virtue of increased soil organic carbon and improved soil aggregation, as well as soil, water, and energy conservation; (iv) SS consisting of no-tillage with substantial crop residue retention offers an alternative to crop residue burning. Strong policies/legislation are required to encourage SS of wheat, in order to limit residue burning, and provide farmers with carbon credits in exchange for carbon sequestration and reduced greenhouse gas emissions.

“…However, along with CMPs, efficient utilization of irrigation water is also needed hourly under the present situation of diminishing water resources. Therefore, to understand the soil-moisture relationship across the soil profile, these irrigation practices are necessary and viable for enhancing the overall sustainability of water and crops [10].…”

In modern agriculture, reducing the carbon footprint and emission of greenhouse gases with greater energy efficiency are major issues for achieving the sustainability of agricultural production systems. To address this issue, a long-term field experiment was established from 2001 through 2016 with two contrasting tillage practices (ZT: zero tillage; CT: conventional tillage) and four irrigation schedules {I-1: pre-sowing (PS), I-2: PS + crown root initiation (CRI), I-3: PS + CRI + panicle initiation (PI)/flowering (FL), and I-4: PS + CRI + PI/FL + grain filling (GF)}. The grain yield of rice, wheat and the rice–wheat system was increased significantly by 23.6, 39.5 and 32.8%, respectively, with irrigation at four stages (I-4) compared to a single stage (I-1). Energy appraisal results exhibited that 17.2% higher energy was consumed under CT as compared to ZT (25,894 MJ Ha−1). Fertilizer application consumed the highest energy (46.5–54.5%), followed by irrigation (8.83–19.5%), and the lowest energy consumption was associated with winnowing, packing and transport (2.07–2.43%) operations. The total energy output of the rice–wheat system did not change significantly among contrast tillage, but higher energy was obtained under CT (214,603 MJ ha−1) as compared to ZT (209,728 MJ Ha−1). ZT practice improved the energy use efficiency (EUE), energy productivity (Ep) and energy profitability (Eprof) by 16.6, 21.0 and 16.6%, respectively, over CT. The EUE, SE (specific energy), Ep, net energy return (NER) and Eprof were enhanced by 17.1, 16.6, 21.0, 36.5 and 20.6%, respectively, with irrigation at four stages (I-4) compared to a single stage (I-1). Zero tillage plots reflected a 8.24% higher carbon use efficiency (CUE) and a 9.0% lower carbon footprint than CT plots. Among irrigation schedules, application of I-4 showed a 8.13% higher CUE and a 9.0% lower carbon footprint over single irrigation (I-1). This investigation indicated that ZT with irrigation at four stages (I-4) was the most sustainable option for improving the EUE and CUE with minimal GHGs emissions from the rice–wheat cropping system of Indian mid-Himalayan regions.

The global population is constantly increasing, reached 8 billion in November 2022 and is expected to reach 9 billion by 2037. This increased population is expected to increase the demand for food, clothing and shelter, which in turn are heavily dependent on limited water resources. The available freshwater resources for agricultural use are further declining due to overexploitation and changing climate in the major food baskets of the world. This increasing water scarcity is exacerbated by expanding cities due to increasing urbanization. This calls for a new look at the allocation of water to agriculture. Therefore, the development of new strategies to improve agricultural water use may serve as an important adaptation strategy. This review attempts to include a comprehensive review of the literature on (i) the status and definition of water productivity and (ii) factors responsible for low water productivity (WP) in Asian agriculture. Furthermore, it contains practical approaches to enhance water use efficiency at the farm level covering all field crops and a range of soil types, which include (i) agronomic interventions; (ii) genetic interventions, such as the identification and cultivation of crop cultivars with high WP; and (iii) genotype, environment and crop management interactions for higher WP.
