In article working out and use questions are considered is information-prediction systems at the decision of a practical problem - a stage-by-stage estimation of productivity of spring wheat in the conditions of Altay territory. The stage-by-stage estimation of productivity under agrometeorological characteristics of years-analogues provides drawing up of forecasts prior to the beginning of vegetation, and also during the vegetative period on a basis prediction models. The problem of anticipatory forecasting of productivity of spring wheat dares by means of methods of statistical processing of the multidimensional data, mathematical modelling, a modern information technology and expert estimations.
