Resource shortages, driven by climatic, institutional and social changes in many regions of Asia, combined with growing imperatives to increase food production whilst ensuring environmental sustainability, are driving research into modified agricultural practices. Well-tested cropping systems models that capture interactions between soil water nutrient dynamics, crop growth, climate farmer management can assist the evaluation such new One model is Agricultural Production Systems Simulator...
The worldwide usage of and increasing citations for ORYZA2000 has established it as a robust reliable ecophysiological model predicting the growth yield rice in an irrigated lowland ecosystem. Because its focus on lowlands, computation ability is limited to representation effects highly dynamic environments upland, rainfed, aerobic ecosystems yield. Additional modules routines quantify daily variations soil temperature, carbon, nitrogen, environmental stresses were then developed integrated...
Abstract Greater nitrogen efficiency would substantially reduce the economic, energy and environmental costs of rice production. We hypothesized that synergistic balancing benefits for soil exploration among root architectural phenes is beneficial under suboptimal availability. An enhanced implementation functional–structural model OpenSimRoot integrated with ORYZA_v3 crop was used to evaluate utility combinations phenes, namely nodal angle, proportion smaller diameter roots, number; L‐type...
Development and testing of reliable tools for simulating rice production in salt-affected areas are presented this paper. New functions were implemented existing crop models ORYZA v3 the cropping systems modelling framework APSIM. Field experiments covering two years, different sites, three varieties used to validate both improved models. We salt balance module model APSIM simulate observed daily soil salinity with acceptable accuracy (RMSEn <35%), whereas measured at a given interval days...
Rice is the staple food for almost half of world population. In South and East Asia, about 40% rice production from deltaic regions that are vulnerable to salt stress. A quantitative approach was developed characterizing genotypic variability in biomass production, leaf transpiration rate net photosynthesis responses salinity during vegetative stage, with aim developing efficient screening protocols accelerate breeding varieties adapted salt-affected areas. Three were evaluated pots under...
Recent studies on yield gap analysis for rice in Southeast Asia revealed different levels of intensification across the main 'rice bowls' region. Identifying key crop management and biophysical drivers gaps provides opportunities comparative analyses, which are crucial to better understand scope narrow increase resource-use efficiencies The objective this study was decompose into their efficiency, resource, technology components map sustainably production four lowland irrigated areas through...
Significance Steady agronomic and genetic interventions helped sustain high annual rice production in an intensive irrigated monoculture system under a changing climate. However, the did not achieve increases yield required to keep pace with growing global demand for because potential was stagnant, apparent biotic constraints limited wet season.
Implementation of environment-friendly soil organic matter (SOM) enhancing technologies (SOMET) is crucial for addressing degradation. This study aims to examine the usage status SOMET (i.e., fertilizer, manure, and compost) from dimension long-term non-usage, dis-usage, late-usage identify drivers these four behaviors usage. We utilized national representative datasets 1659 Bangladeshi rice-farmers periods 2013, 2016 2020 with climate hazards data. Households were categorized into non-user...
Abstract Mountain rye (MR: Secale strictum syn. S. montanum) is a forage grass that considered candidate for perennial grain development in Australia. A greater understanding of the triggers flowering would aid integration this dual-purpose into Australian grazing and cropping systems. The objective experiment was to determine effects cold incubation (vernalisation) periods varying duration on yield, biomass production, phenology MR, compared dual purpose annual winter wheat cultivar...
Asian Mega-Deltas (AMDs) are important food baskets and contribute significantly to global security. However, these areas extremely susceptible the consequences of climate change, such as rising temperatures, sea-level rise, water deficits/surpluses saltwater intrusion. This study focused on maize crop suitability mapping yield assessment in two major AMDs: Ganges Delta, spanning parts northeast India Bangladesh, Mekong Delta across Vietnam Cambodia. We investigated historical reanalysis...
With rapidly increasing investment in water control infrastructure (WCI) and a recently ratified agriculture development strategy that promotes integrated farming of high-value products such as fish, agricultural production, already fundamental to Myanmar’s economy, will be central driving the countries’ socioeconomic transformation. Water planners managers have unique opportunity design manage WCI incorporate fish and, so doing, reduce conflicts optimise benefits both people ecosystem...
While climate information services are widely available, translating into actionable solutions to reduce risk, which readily taken up by producers, remains a critical challenge. Here, we apply bio-economic approach assess the potential economic value of seasonal forecasts (SCFs) as basis for use in agricultural decision-making. We case study approach, quantifying impacts precipitation on rice cropping, dominant farming system Greater Mekong Region (GMR) Southeast Asia. demonstrate values...

Abstract Sustainable Soil Management Practices (SSMP) offer potential benefits while conserving natural resources. However, the low adoption of SSMP limits achievement their full potential. To examine current state knowledge on and identify research gaps, we systematically reviewed 269 peer‐reviewed publications pooled from Scopus, Web Science ScienceDirect, covering period 1994 to 2022. We assessed temporal spatial transitions identified a broad perspective 14 themes highlight trends gaps....
