Summary: This study assessed the energy and carbon footprints, energy and carbon production efficiency, and economic benefit of direct-seeded rice, wet direct-seeded rice, and transplanted rice. The results showed that wet direct-seeded rice and transplanted rice had higher yields than direct-seeded rice. However, direct-seeded rice had lower energy input and carbon footprint, and higher energy and carbon production efficiency. Its economic benefit was not lower than wet direct-seeded rice and transplanted rice.

Summary: Dry direct-seeded rice is a popular rice production technology in many Asian countries, but weeds remain a major challenge for its establishment and productivity. Chemical weed management is effective but has negative impacts on the environment and human health, making integrated weed management the best option for sustainable rice production under this system. Competitive rice cultivars and high seeding rates were found to be promising strategies for integrated weed management in dry direct-seeded rice systems.

Summary: This study proposes a device for seedbed clearing and shaping of dry direct-seeded rice in order to remove stones, break soil blocks, level the soil, and form grooves. The overall structure and roller of the device are developed based on theoretical calculations, discrete element modeling (DEM) simulations, and field tests. The optimization parameters combination of the device obtained by simulation experiments ensures stable and reliable performance.

Summary: Conservation agriculture management practices, such as cover crops and residue retention, have been found to improve soil quality and environmental sustainability in dryland cropping systems. The long-term adoption of cowpea cover crops could be a potential practice to sustain crop productivity with environmental co-benefits, especially in the wetter regions of southeast Australia.

Summary: There is a lack of studies evaluating the complexity of grass growth models suitable for simulating grass growth in intensive grassland production systems. Therefore, two different grass growth models (GrasProg1.0 and APSIM) were compared against long-term observations from variety trials with perennial ryegrass in Germany and Denmark. The results showed that both models provided satisfactory results, indicating that the less complex GrasProg1.0 model can be incorporated into a simple decision support tool for optimizing grassland management in intensive livestock production systems.

Summary: A study was conducted to investigate the effects of different nitrogen fertilizer doses on the growth and yield of hybrid rice in a coastal ecosystem. The Agricultural Production Systems Simulator (APSIM) model was used to simulate the physiological changes of hybrid rice under varying nitrogen rates. The model showed good accuracy in predicting the effects of nitrogen on hybrid rice, although it slightly overestimated the amount of nitrogen stored in the plant's organs in the calibration data. However, this overestimation was corrected in the validation data, and a strong correlation was found between the observed and simulated nitrogen amounts.

Summary: Despite favorable hydro-edaphic conditions, lowland rice yields in East Africa remain low due to variations in cultural management practices and poor understanding of interactions. Multi-year field experiments in Tanzania and Uganda revealed the potential to boost yields beyond current regional means, with water table data playing a crucial role in model performance and highlighting the impact of water and N stress on yield.

Summary: The timing of rice planting significantly affects the productivity and resilience of the rice-wheat cropping pattern in the IGP. Synchronizing rice planting dates with the monsoon onset improves performance in the Eastern IGP, while fixed planting dates or planting medium duration varieties at monsoon onset perform best in the Northwestern IGP.

Summary: The study found that in Bangladesh's saline coastal zone, early planting of Boro rice to utilize early-season fresh water resources can significantly increase farmer profits and regional production. To achieve this advantage, farmers need to adopt early-maturing rice varieties in the monsoon season, and synchronize agronomic timings with fellow farmers and cooperate in sluice-gate management.

Summary: This paper explores the responses to cattle management practices introduced during a research project and examines the perceptions and application of new knowledge by farmers, extension staff, and policy makers. By taking a longer-term view, it demonstrates how farming households adapt and integrate knowledge from different sources into their daily practice. The focus on building capacity and empowering farmers with information to adapt and respond to change is considered a more important goal and indicator of impact than measuring adoption.

Summary: In East Africa, the yield responses to nitrogen fertiliser vary between different wetlands and years. The use of locally-validated APSIM model has shown that mineral nitrogen fertiliser can significantly increase rainfed rice yields and nitrogen use efficiency, making it profitable for smallholders. Supplemental irrigation can further enhance nitrogen fertiliser use efficiency and profitability. Spatial-temporal water stress pattern simulation can guide efficient irrigation scheduling.
