Rice Production, Augmentation, Escalation, and Yield Under Water Stress

Rice (Oryza Sativa) is a grass and highly stipulated cereal crop. Water stress is an existing and future trauma to rice production. It severely manipulates plant growth and production that ultimately results in yield loss. Cell size, molecular activities, tissue formation, organ establishment, flower formation, reproduction mechanism, grain fabrication, and seed maturation are partially or fully interrupted. Flowering stage is more susceptible to water stress. Reproductive organs are structurally and functionally influenced. Fertilization failure or grain filling loss and immature seed formation could result. Yield loss happens less severely when water stress occurs during vegetative phases but is more severe during panicle growth. Water stress and its tolerance to rice crop are therefore considered the critical issue under study and research. Various institutes and scientists worldwide are trying to explore new ways and schemes to overcome this strain. New ways are being investigated by providing suitable alternative rice harvesting strategies than traditional ways of cropping. Most of the Asian countries are still habitually grown rice in abundance water as they are doing so from over the years. In different agro-ecosystems, water is going to scarce, but it is provided by the farmer by fetching through different sources. Because farmers are in fear of crop loss and yield loss in case water is unavailable to their routine cropping, they must be encouraged by introducing water efficient use and water stress-tolerant practices in rice cropping. Scientific exertions in this contemplate still in progress to achieve free of yield loss adopted policies and approaches. This assessment is a part of scientific advancement to examine and inspect rice crop effects under water stress.
