The estimation model of agroclimatological resources of the territory which takes into consideration the biological peculiarities of vegetable craps is worked out on the base of maximum productivity conception. The regularities of formation of agroclimatological condition of growing and yield formation in different agroclimatological condition are shown here. The quantitative estimation of influence of agroclimatological characteristics exchangeability on the plant process productivity is received.
The problem of influence of level of plant mineral nutrition on productivity is under consideration in the paper. Computation equations for the effect of the application rates of fertilizers on productivity of dry standing crop are derived. All the parameters of the equations are juxtaposed with plant physiology. Estimation of influence of mineral nutrition level on the processes of photosynthesis and respiration is given. The computation can be used at crop capacity sequencing.
