Summary

Study of rice field terracing impact on filtration rate, soil salinity, water mineralization and rice yield; rice field water-salt balance depending on micro-relief; economic grounding optimal parameters of rice field micro-relief Massif is located within a desert and semi-desert zone with continental climate. Soil can be divided into two layers: top-3m thick-loam and lower-60m thick-sandy loam. Irrigated area 33ha. Water supply and disposal is made through earthen canals. Equations and models are developed describing dependence of rice yield of terracing degree, irrigation norm, water salinity and filtration rate; main factors are revealed influencing yield. Economic assessment is done on rice field relief parameters on rice systems productivity.

Key words

Soils, rice systems, rice field, water-salt regime, filtration, irrigation norm
