Abstract
Rice (Oryza sativa L.) is a crucia cereal crop that supplies around half of the Earth‟s people within 6% of the daily calorie intake. It is worth noting that to meet global needs in 2035, rice productivity must be increased by 26% (United Nations 2019). Various drawbacks restrict, the yield of the rice crop and have a devastating impact on rice cultivation including, pest infestation, unfavorable environmental conditions accompanied by climate change, salinity stress, insufficient nutrients, and deficit irrigation (DI) as a result of an emerging shortage of water resources.
