Purpose: development of a current model of water consumption rationing and calculation of the corresponding rates and terms for agricultural crops irrigation under various hydrometeorological parameters.
Materials and methods: the basis for the developed model is a series of field experiments conducted in 2012–2014, as well as analytical studies, the scheme of the experiment, soil and hydrometeorological characteristics, water balance dynamics, precipitation and total moisture supply of the irrigated massif, water consumption according to the development stages of summer planting potatoes were determined.
Results and discussion: the model under consideration includes taking into account the water-physical properties of soil, the lowest moisture capacity and moisture reserves, setting critical limit for the irrigation regime, temperature and air humidity deficit, the duration of the growing and inter-irrigation periods, on the basis of which the water consumption of the selected crop is calculated according to the growth phase. Further, the irrigation regime is calculated: the irrigation rate and the difference in moisture reserves, which comparison with the critical limit allows to conclude on irrigation necessity or its prediction for the near future (up to five days) after which irrigation will be needed. A complex for differentiating the irrigation regime with the determining deficits and standards for the parameters under consideration is provided.
Conclusions: the model of water consumption rationing, performed on the use of two hydrometeorological factors, taken into account the growth and development phases of the crop under consideration, makes it possible to substantiate the actual calculation of the corresponding norms and terms of agricultural crops irrigation. The model is stable and can be used in land reclamation practice as a part of general technological complex for agricultural crops cultivation on irrigated lands.
