Summary: Increasing productivity per unit area is crucial for meeting cereal demand in sub-Saharan Africa. This study evaluated the contribution of recommended agronomic practices (RAP) and fertilization on closing the yield gap. Results showed that RAP and farmer-selected best practices significantly increased grain yield, while NPK fertilization further enhanced the yield. Different agronomic practices have varying effects on reducing the yield gap and need to be considered in terms of cost and fertilizer prices.

Summary: The study aimed to improve rice farmers' productivity and profitability in rainfed lowlands of Indonesia by closing the yield gap during the dry season. By comparing recommended practices with farmers' current practices, the research found that implementing improved varieties and nutrient management, along with water reservoir infrastructure and information access, significantly increased rice yield and net returns. This suggests there is potential to increase rice production in rainfed lowlands through appropriate crop and nutrient management, supplemental irrigation, and reducing the yield gap.

Summary: A study compared the trap success of multiple-capture traps with linear trap barriers to single-capture traps in rice fields in Indonesia and the Philippines. It found that multiple-capture traps were significantly more effective in catching rodent pest species and capturing more individuals and species of rodents, indicating their higher efficiency in monitoring and controlling rodent populations.

Summary: A successful experiment was conducted at the Federal University of Agriculture, Abeokuta in Nigeria to study the influence of integrated nutrient sources on the performance of two lowland rice varieties. The experiment used a split-plot two-factorial design and collected data on rice yield and growth. The results showed that ARICA 3 outperformed NERICA L-34 in terms of growth and harvest data.

Summary: The rice yield in Thailand has shown different growth patterns over the past 45 years, closely related to changes in irrigation water availability, increased fertilizer application, proportion of high-yielding varieties adopted in different regions, and continuous agronomic improvement. The dominance of varieties with high grain quality but limited yield potential in Northeast Thailand highlights the importance of grain quality in determining total rice production.

Summary: Rice yields in Uruguay have increased rapidly between 1990 and 2013, but there are signs of a recent slowdown. This study aimed to determine if the slowdown is due to the average yield approaching the yield potential ceiling. By using a simulation model and weather data, the study found that there is still room for increasing rice yields in Uruguay.

Summary: This study used Kansas, the largest wheat producing state in the U.S., as an initial assessment to quantify yield gaps and identify key management factors. The research discovered that management practices such as nitrogen, phosphorus, and sulfur fertilizer, as well as foliar fungicide, played significant roles in grain yield, with interactions varying across different seasons and regions.

Summary: We conducted field experiments to study the effect of weather variables on rice yield across five rice ecologies in India. We found that different weather elements have different effects on rice yield in different rice ecosystems. Critical thresholds for above average, average, and below average yield were identified for each ecology. Factors such as minimum temperature, rainfall, and bright sunshine hours were found to significantly impact the yield. Additionally, we found that the rice cultivar Swarna performed differently at different sowing dates and locations.

Summary: Iron (Fe) toxicity is a major challenge for plant cultivation in acidic waterlogged soil environments, particularly for lowland rice, a staple food crop. A study identified genes related to excess Fe tolerance in rice, which could be crucial for targeted breeding of rice crops for increased Fe tolerance during domestication.

Summary: Arable land is facing challenges due to social development and environmental anomalies, impacting food security. Future food security relies on improving yield per unit area, specifically by breeding high-yield, stable-yield, and climate-resilient rice varieties. Variety improvement has significantly increased rice yields and stability from 1991 to 2017, with differences across regions and rice types. Variety improvement has also changed rice yield sensitivity to climate resources, particularly solar radiation and accumulated temperature, helping to maintain or increase yields under environmental challenges like climate change.
