Navigating environmental challenges in rice cultivation for food purpose

Rice, the crucial staple crop, is threatened by widespread climate change impacts on its cultivation. The rice agronomic traits including plant height, tiller number, leaf number, panicle count, and overall yield are strongly dependent on environmental factors such as day length, temperature, rainfall and soil parameters. Rice growth is affected by temperature fluctuations leading to heat stress or cold damage, which diminish yields, and decreases grain quality. High and low rainfall conditions have negative effects on growth conditions, as plant height, tiller number and grain yield are reduced. Genes interact with soil parameters such as texture, pH and nutrients, organic matter content to influence rice growth. Good soil conditions will further benefit nutrient absorption and root development, and will in turn benefit agronomic performance. However, the plant height, tiller production, and yield are all limited by suboptimal soils with nutrient imbalances or poor structure. This is important for developing rice varieties that are resilient to changing climatic conditions by understanding the complex interactions of genetic and environmental factors. Rice breeders and farmers can help produce more resilient varieties to thrive under adverse conditions with genetic tools and good environmental management to achieve food security and economic profitability.
