Definition of fertilizer amount for different varieties of dry beans on the basis of the direct use of field experiment results

Studies were conducted following the methodology “ISSPOD - OmSAU (Integrated System of Soil and Plant Operational Diagnostics)”. The aim of the research was to create the optimal conditions for feeding dry beans on the meadow-chernozem soil of Western Siberia. The object of the research were dry beans ( Phaseolus vugaris L. ) of different varieties - Olivkovaya, Sirenevaya, Luker’ya. Field experiments were carried out on shallow meadow-chernozem soil with low content of humus and high content of loam following a scheme consisting of eight options with the introduction of different doses of mineral macrofertilizers. The effect of different doses and compositions of mineral fertilizers under the conditions of Western Siberia on the yielding capacity of dry bean varieties has been studied. Depending on the different doses and compositions of fertilizers, the increase in the yielding capacity of beans ranged from 0.4 to 2.9 t/ha. Fertilizer treatment had a positive impact on the harvest volume of the crop at study. In addition, the results of the field experiments provide a means of calculating the rates of fertilizer treatment for each particular variety. For each variety, different options of the field experiment scheme have proven to be optimal for the cultivation of beans.
