On the Issue of Planning Sowing Agricultural Crops With the Minimum Risk Under the Presence of Various Agroclimatic Conditions

“…x x x = is a column vector, x means Euclidean norm. Therefore, for any sequence x x ) is not an infinitely growing function on 2 . X =  Indeed, since ( ) ( )…”

“…where i N means the number of years for which statistics on the yield by the kind of crop has been collected. Fields (including the current cultivated field under consideration) with more or less similar soil characteristics under different agroclimatic conditions: see [2], [3], [36], [40] are considered. Using statistical methods, having properly processed [42]- [47] the known empirical data…”

“…Now let us find out whether the found local minimum * x ∈ Ω of the optimization problem ( 5) is also its global minimum. For this, we note that the objective function ( ) 2 x σ of problem ( 5), if we consider it as a quadratic form, is a canonical form with positive coefficients, and, therefore, it is a positive definite quadratic form at…”

“…Crop yields are very sensitive not only to soil fertility indicators, but also to climatic indicators, the main of which are temperaturehumidity and temperature-wind (taking into account radiation) indicators. Together these indicators are called soil-climatic indicators (conditions), and it is these conditions that determine the success or failure of all stages of the process of growing crops [2]- [12]. The yield of crops by country, depending on soil and climatic conditions, crop farming, as well as macroeconomic conditions, is quite different.…”

On One Scientifically Based Sowing Management for Getting Pareto-Optimal Crops Harvest

“…Together these indicators are called soil-climatic indicators (conditions), and it is these conditions that determine the success or failure of all stages of the process of growing cereal crops -the stage of selecting a variety of grain culture, its vernalization, the stages of processing and preparing the soil, the stages of determining the optimal sowing time and optimal seeding rates, stage of seed treatment, stages of seasonal treatment of crops, etc. [2], [3], [6], [7]. The yield of cereal crops by country, depending on soil and climatic conditions, crop farming, as well as macroeconomic conditions, is quite different.…”
