Abstract Increasing water shortage and low water productivity in the irrigated drylands of Central Asia are compelling farmers to adopt resource conservation technologies, such as dry seeded, non-flooded rice. Alternate wet and dry (AWD) water management combined with alternative establishment methods, e.g., zero tillage planting in bed and flat layouts, and residue retention, may substantially reduce rice irrigation water requirement. Field experiments were conducted in a rice–wheat cropping… 
Parameterization and modeling of paddy rice (Oryza sativa L. ssp. japonica) growth and water use in cold regions: Yield and water-saving analysis
Abstract Rice is the high-water consumption crop that feeds more than half of the world population. The planting area of cold region rice is expanded rapidly in recent years due to the high market
Comparative advantages of conservation agriculture based rice–wheat rotation systems under water and salt dynamics typical for the irrigated arid drylands in Central Asia
Abstract In Central Asia, the increasing water shortage and labor scarcity, high cost of production, increasing secondary soil salinization, and land abandonment are compelling farmers to change to
Simulating the impact of water saving irrigation and conservation agriculture practices for rice–wheat systems in the irrigated semi-arid drylands of Central Asia
Abstract Resource scarcity (labor, water, and energy) and high production costs are challenging the sustainability of conventional methods for rice and wheat establishment in Central Asia. Water
Impact of alternate wetting and drying on rice physiology, grain production, and grain quality
Results indicate that plants grown under safe AWD conditions at this site have an increased grain mass compared to plants growing under CF, and this may be partly due to a high number of productive tillers.
Effects of Alternate Wetting and Drying Irrigation Regime and Nitrogen Fertilizer on Yield and Nitrogen Use Efficiency of Irrigated Rice in the Sahel
The objectives of this study were to investigate water saving strategies in the paddy field and to evaluate the performance of some of the newly released rice varieties. Field experiments were
Aerobic Rice with or without Strategic Irrigation in the Subtropics
It is important to consider variations in flowering time, yield potential, and drought patterns when developing rice varieties for rainfed semi-arid tropical conditions, as well as when quantifying the benefits of strategic irrigation.
Increasing profitability, yields and yield stability through sustainable crop establishment practices in the rice-wheat systems of Nepal
Abstract The rice-wheat rotation is the dominant cropping pattern in the Terai ‘food basket’ of Nepal. Current production practices require significant labor, water, and energy which erode
Mulching Improves Water Productivity, Yield and Quality of Fine Rice under Water‐saving Rice Production Systems
Water-saving rice production systems are inevitable in the wake of severe water shortage in rice-growing regions of the world. Mulches can improve water productivity, yield and quality of rice
Agro-environmental sustainability of different water management practices in temperate rice agro-ecosystems
Water management practices alternative to continuous flooding are highly required to enhance water use efficiency and safeguard environmental quality in temperate rice agro-ecosystems. In this work,
Effect of Crop Management Practices on Crop Growth, Productivity and Profitability of Rice–Wheat System in Western Indo-Gangetic Plains
An experiment was conducted with three managements varied in tillage, crop establishments, residue, fertilizer, water to evaluate crop behaviour, irrigation water use, crop productivity and


Mineral nitrogen dynamics in irrigated rice–wheat system under different irrigation and establishment methods and residue levels in arid drylands of Central Asia
Abstract Increasing water shortage and low water productivity in the irrigated drylands of Central Asia are compelling farmers to develop and adopt resource conservation technologies. Nitrogen (N) is
Effect of water management on dry seeded and puddled transplanted rice. Part 1: Crop performance
Abstract An alarming rate of ground water depletion and increasing labour scarcity are major threats to future rice production in north west India. Management strategies that reduce the irrigation
Yield potential and water use efficiency of aerobic rice (Oryza sativa L.) in Japan
Abstract Intensive rice farming in aerobic soil, referred to herein as aerobic rice, can greatly reduce the water input compared to that of flooded rice cultivation. The objective of this study was
Evaluation of alternative tillage and crop establishment methods in a rice-wheat rotation in North Western IGP
Direct-seeded or transplanted rice after no-tillage can be more efficient and profitable alternatives to current practice (puddled transplants rice), however, require further refinement in areas of cultivar development for no-Till direct-seeding condition, nutrient, water and weed management to harness maximal potential.
Growth, yield and water productivity of zero till wheat as affected by rice straw mulch and irrigation schedule
Intensive cultivation of rice and wheat in north-west India has resulted in air pollution from rice straw burning, soil degradation and declining groundwater resources. The retention of rice residues
Saving of Water and Labor in a Rice–Wheat System with No-Tillage and Direct Seeding Technologies
Conventional tillage and crop establishment methods such as puddled transplanting in the rice-wheat (Oryza sativa L.-Triticum aestivum L.) system in the Indo-Gangetic Plains (IGP) require a large
Effect of water-saving irrigation on rice yield and water use in typical lowland conditions in Asia
Abstract With decreasing water availability for agriculture and increasing demand for rice, water use in rice production systems has to be reduced and water productivity increased. Alternately
Rice production in water-scarce environments
Rice production in Asia needs to increase to feed a growing population. Though a complete assessment of the level of water scarcity in Asian rice production is still lacking, there are signs that
Field water management to save water and increase its productivity in irrigated lowland rice
Abstract Rice production in Asia needs to increase to feed a growing population whereas water for irrigation is getting scarcer. Major challenges are to (i) save water; (ii) increase water
The implications of land preparation, crop establishment method and weed management on rice yield variation in the rice–wheat system in the Indo-Gangetic plains
Yielding of dry seeded rice sown after dry cultivation of soil were broadly comparable with those of transplanted rice, providing weed competition was absent, and support the proposition that direct seeding of rice could provide an alternative to the conventional practice of transplanting.
