Agrotechnological assessment of the application of biological preparations and micronutrient fertilizers in spring wheat

The results of the research on assessment effectiveness application biological fertilizer Humistim and micronutrient fertilizers MicroFeed Complex Extra Phosphorus in cultivation spring wheat under conditions Kursk Region are presented. As a result research, it was found that preparations (Humistim, Phosphorus) contributed to better growth development wheat, reduced leaf-stem diseases, increased yield quality grain. Thus, when treating seeds (5 l/t) crops tillering phase early booting l/ha) with fertilizer, septoria 16.4 %, efficiency 36.4 by 0.55 t/ha, gluten content grain 2.1%, compared control variant. When using at rate 1.5 l/t for seed treatment l/ha crop slightly lower amounted -32.6-33.7 0.52-0.53 1.7-1.9 %. Calculations economic showed direct production costs 825 rubl./ha, but due increase yield, cost gross 6,600 conditional net income 5,775 1 ton decreased 511.55 rubles. micronutrients similar methods lower: value 27,693.31-30,255.31 rubl./ha. provided minimum 2,940 rubles/ha, which is its higher cost.
