“…They also reported that an increase in soil salinity build up averaged over soil profile in irrigation at 60% of the Chinese pan evaporation was very small over original soil salinity. Singh et al (2018) reported that the application of irrigation water through a sprinkler or low energy water application each at 2 days interval with 4 cm depth at each irrigation significantly improved the water productivity and energy productivity over a surface method of irrigation with a similar level of rice grain yield in all irrigation systems. This finding again reports the successful use of a micro-irrigation system in problematic soil.…”

Soil is an important natural resource providing water, nutrient, and mechanical support for plant growth. In agroecosystem, continuous manipulation of soil is going on due to addition of input, removal of nutrients, changing water balance, and microbial life. These processes affect soil properties (physical, chemical, and biological), and the deviation of these properties from the normal status is controlled by soil buffering capacity and soil resilience. If these changes are beyond the reach of soil resilience, then soil loses its original state, leading to soil degradation. At present, the extent of the degraded area in the world is 1,036 to 1,470 million ha. This urges the need for maintaining soil health rather than the mere addition of input for crop production. Soil health is an integrative property that reflects the capacity of soil to respond to agricultural intervention, so that it continues to support both agricultural production and the provision of other ecosystem services. Maintaining the physical, chemical, and biological properties of soil is needed to keep it healthy, and this is possible through the adoption of different agronomic approaches. The diversification of nutrient sources with emphasis on organic sources, adoption of principles of conservation agriculture, enhancement of soil microbial diversity, efficient resource recycling through the integrated farming system, and amendment addition for correcting soil reactions are potential options for improving soil health, and are discussed in this review. This article reviewed the concept of soil health and its development, issues related to soil health, and indicators of healthy soil. At the same time, the impact of the ill health of the soil on crop productivity and resource use efficiency reported in different parts of the world in recent years are also reviewed. The agro-techniques such as green and brown manuring in arable land and agroforestry on degraded and marginal land were followed on piece meal basis and for economic gain. The potential of these and several other options for maintaining soil need to be recognized, evaluated, and quantified for their wider application on the front of soil health management avenues. The use of crop residue, agro-industrial waste, and untreated mineral or industrial waste (basic slag, phosphogypsum, etc.) as soil amendments has a huge potential in maintaining healthy soil along with serving as sources of crop nutrition. The review emphasizes the evaluation and quantification of present-day followed agro-techniques for their contribution to soil health improvement across agro-climatic regions and for wider implications. Furthermore, emphasis is given to innovative approaches for soil health management rather than mere application of manures and fertilizers for crop nutrition.

“…Varieties MICHAEL T. AIDE were also shown to be important yield predictors. Singh et al (2018), in India, observed rice production on sodic soils having treatments involving (i) A traditional farmer-use irrigation practice, (ii) Sprinkler irrigation and (iii) A low energy water application device. Sub-treatments involved irrigation frequency.…”

G LOBAL rice production remains critically import for food security; however, fresh water is an ever-increasingly diminished resource. The objective of this manuscript is to select central and comprehensive research focusing on rice production and diminished water availability to isolate and authenticate emerging initiatives to address continuance of rice production and to ensure water sustainability. Three regions were selected: (i) Asia with an emphasis of China and India, (ii) The United States of America and (iii) The Mediterranean region with an emphasis on Egypt. Each of these regions recognize current or emerging issues associated with water quantity, water quality, urbanization, climate change and other technological, social and policy constraints; however, each region has a different hierarchy of issue importance. China and India recognize climate change, aquifer overdraft and pollution of water resources as central issues, whereas the mid-South region of the United States of America is more focused on irrigation technology to improve farm profitability. Egypt is primarily focused on water quantity and quality limitations, with substantial research addressing desertification and saline soils/water. This review focuses on stated research objectives in compelling, peer-reviewed literature to indicate regional approaches addressing the causes of restricted water availability for rice production and the most-probable approaches for maintaining rice production to safeguard food security and producer profitability. Thus, unique rice water management approaches are predicated on the region's water quantity and quality environmental assessment.

“…The higher values were achieved when the irrigation schedule was based on AWD (alternate wetting and drying) at a 5-day interval. Singh et al (2018) while evaluating different methods of irrigation report that the use of a LEWA (Low Energy Water Application) device and Sprinkler may double the irrigation water productivity in rice crops. The irrigation water productivity reported for a surface method of irrigation was 4.63 INR/m 3, whereas in the case of the Sprinkler and LEWA device, it was 7.28 and 7.38 INR/m3, respectively.…”

Productive use of water reflects better food and nutrition for families, more income, and productive employment. Targeting high water productivity can reduce the cost of cultivation of crops and lower energy requirements for water withdrawal. For several decades, researchers have made efforts to enhance water use efficiency. The primary objectives of these efforts were to conserve water rather than reflect the economic gains of water use. With the growing demand for water by sectors other than agriculture, the focus has changed, and the emphasis is more on the net economic return per unit of water used. This objective can be well addressed by assessing the water productivity of irrigation practices as the term water productivity is used to more accurately characterize the relationship between the output or income (such as biomass or yield) and the volume of water resource. At the same time, WUE measures the ratio or percentage of effective water demand to water consumption. Considering this concept, this paper presents the performances of different irrigation regimes in rice and wheat crops grown under a sodic environment regarding water productivity. The irrigation regimes are a combination of varying depths and varying irrigation schedules. In rice crops, ten combinations of irrigation regimes were developed by varying two irrigation depths (5 and 7 cm) and five scheduling techniques (2 DAD (days after the disappearance of ponded water), 3 DAD, 5 DAD, 7.5 kPa and 10 kPa in rice. Similarly, two irrigation depths (3 and 5 cm) and five scheduling techniques (30% SMD (Soil Moisture depletion), 50% SMD, 70% SMD, IW/CPE ratio -0.8 and IW/CPEratio 1.0 in wheat crop. One control each in rice and wheat considering farmers' practices in the area was considered for comparison. The results reflect that the irrigation regime of applying 5 cm irrigation depth at 3 to 5 DAD in rice may result in higher irrigation water productivity (IWP). The observed values of water productivity in rice were 1.18 and 0.9 when 5 cm irrigation depth was scheduled at 5 DAD and 3 DAD respectively. In the wheat overall irrigation regime, applying 5 cm irrigation depth at the IW/CPE ratio 0.8 performed better. The irrigation water productivity value observed in this case was 2.27 kg/cubic m of water used. The results were further analyzed to decide the best-performing schedule for the RW cropping systems by combining the results under different irrigation regimes. Applying 5 cm irrigation depth at 5 DAD in rice and at an IW/CPE ratio of 0.8 may lead to optimum water utilization and higher crop yield, in the RW cropping system,.
