Citation: Korres, N., Bararpour, T., Slaton, N.A., Price, A.J. 2018. Effects of salinity on rice and weeds: Short- and long-term adaptation strategies and weed management. In: Hasanuzzaman,M., Fujita, M., Nahar, K., Biswas, J., editors. Advances in Rice Research for Abiotic Stress Tolerance. Cambridge, MA: Publishing/Elsevier. p. 159-176.

Interpretive Summary: Rice (Oryza sativa L.) is an important staple crop that feeds more than one half of the world’s population. Salinity has been a key abiotic plant stress damaging crop production worldwide. Rice, as the most sensitive cereal crop to salinity, is particularly at risk to salinity stress due to crop irrigation and flooding weed control practices. Therefore, understanding causes and the related consequences of salinity on rice is needed to counteract negative effects. In addition, weed competition and management is one of the major constraints of rice production due to environmental selection of saline tolerant troublesome weed species over time. Thus, weed population dynamics and composition in saline environments is different compared with traditional rice cultivated environments. These issues will be addressed in this chapter in an attempt to highlight the most important factors and challenges, as well as suggest short- and long-term adaptation strategies, in this complex production system. Information provided in this chapter may also assist to determine the potential of rice weed occurrence in saline areas potential efficacious control methods.
