METHOD AND DEVICE OF DETERMINING LEVEL OF AGRO-TECHNOLOGIES EFFICIENCY Russian patent published in 2013 - IPC A01G7/00 A01G9/24 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to the field of agriculture. In the method from a large number of variables the variable of order is selected in a complex multifactorial system "plant - environmental factors", changing the most rapidly and influencing most strongly on the processes in the system. Also the control parameters are chosen by which it is possible to carry out the influence on the productive processes of plants. At that the level of effectiveness of agro-technologies is determined by the ratio of the value of the exergy of the variable of order in the actually obtained crop production, in the experiment with the estimated agro-technology to the value of the theoretical exergy of the variable of order obtained by calculating from the expression: η(%)⁼℮_"рпц"/℮_tpp where η is an indicator of the effectiveness level of optimality of agro-technologies, ℮_"рпц" is real yield in exegetical units, ℮_tpp is theoretical value of potentially possible yield under the given environmental conditions in exegetical units. The device comprises a sensor of exergy of optical radiation for crop production, the unit of estimated value calculation of exergy of power of exergy of optical radiation, a storage unit. The device comprises the unit of determining the level of efficiency of agro-technologies. At that the output of the unit of exergy of power calculation of optical radiation is connected to the first input of the unit of determining the level of efficiency-optimality of agro-technologies, the output of the storage unit is connected to the second input of the unit of determining the level of efficiency of agro-technologies, and the output of the unit of determining the level of efficiency of agro-technologies is connected with the operator agro or the input of the information system.

EFFECT: inventions enable to increase the productivity of plants by plant cultivation taking into account the environmental conditions of the land.
