Predictive Assessment of Changes in Water Needs of Accompanying Crops of Rice Crop Rotation in Changing Modern Conditions

Abstract

The chapter considers an approach for assessing and forecasting the water needs of accompanying crops of rice crop rotation in changing modern conditions of rice irrigation system's functioning. The obtained results can be effectively used in the development of adaptive measures to the climate changes in the context of water, energy, and food crises, as well as in the justification of resource-saving regimes and technological solutions in projects of reconstruction and modernization of rice systems aimed at achieving the goals of optimizing the use of water and energy resources during their functioning. The chapter presents the results of a machine experiment on the predictive assessment of the water needs of accompanying crops in variable natural-agro-melioration conditions of the Danube area. The conditions of the water needs formation for various types of accompanying crops were determined according to accepted schemes of technologies and water regulation regimes on irrigated lands of rice systems. A comparison of the obtained results with real production data was carried out.
