The article presents research based on which the biotechnology of land reclamation in rice crop rotations after fish fallow to improve water and land resources efficiency of rice systems is developed. Irrigation regimes’ influence on rice yield and grain quality was studied. Vegetation experiments and field studies were carried out to establish the place of fish fallow and rice share in the fish/rice crop rotation composition. It is established that after fish fallow the highest Rapan rice variety yield is obtained at shortened and periodic flooding with 5 cm layer up to tillering phase. Under the shortened flooding regime, the qualitative indicators of rice grain and straw in terms of macronutrients content are the best in comparison with other regimes. The most balanced rice irrigation regime under the studied conditions is the regime with periodic flooding with a water layer of 5 cm.
