Bio-power efficiency of dusting of seeds microcells (Zn, Cu, Mn) at cultivation of the spring-sown field in the conditions of the forest-steppe of Western Siberia
Results of use of dusting of seeds by microcells for increase of productivity of grain of a spring-sown field are presented. Field and laboratory methods are involved in work. In the researchers conducted in 2009-2012 on the meadow and chernozem soil in the conditions of the forest-steppe of Western Siberia efficiency of dusting of seeds by microfertilizers (Zn, Cu, Mn) a spring-sown field of a grade "Duet" against the balanced nitrogen-phosphorus-potassium food is established. Introduction as macrofertilizers (N60P60K60), and microfertilizers (Zn, Cu, Mn) considerably increased productivity of grain of the studied culture. All increases were essential. The maximum productivity of grain was in Zn50Cu50Mn50 option made 3.00 t/hectare. The greatest payback of the introduced fertilizers under a spring-sown field in option of combined use of microfertilizers. In these options each brought kilogram of fertilizers calculated on the basis of optimum levels of the maintenance of macrocells in the soil paid off from 2.8 to 5.8 kg of grain. Thus, payback of macrofertilizers increases when dusting seeds microcells. The importance of a power assessment arises from a disproportion between energy consumption and power production, that is it is necessary to define degree payback of power expenses of the energy which is saved up in a crop. At combined use of macrofertilizers and microfertilizers power costs of receiving additional ton of grain decrease, from the point of view of power efficiency of use of fertilizers, in more effective options. Calculation of bio-power efficiency showed that in the best option of introduction of microcells of efficiency is equal 6.31. Thus, calculation of power efficiency of use of fertilizers allowed most precisely, objectively and comprehensively to estimate system of fertilizers in all technological processes connected with culture of a spring-sown field.
