Influence of Bioactivesoil combined fertilizers on yield and quality of spring hard and soft wheat

The experimental data on effect of Bloom & Grow and Immune System fertilizers on growth, development, yield and grain quality of spring durum and soft wheat in light gray forest soils of the Chuvash Republic are presented. The results of two research years revealed that in plants treated with fertilizers, the growth period ‘seedling-ripening’ is reduced by 7-8 days, height of the treated soft wheat plants exceeded the control variant by 12.5 cm, length of the main spike - by 0.4 cm, number of grains per spike - by 6.1, and grain mass per spike - by 0.23 g. Plants of spring durum wheat treated with micronutrient fertilizers exceeded the control variant by 25.1 cm in plant height, length of the main spike, number of grains in it and grain weight significantly exceeded the control variant. The 1000 seed mass exceeded the control variant by 7.28 grams. The increase in the yield of spring soft wheat was 0.89 t/ha (26.3%), and durum wheat - 0.93 t/ha (28.6%). Application of Bloom & Grow and Immune System fertilizers led to an increase in gluten content in spring soft and durum wheat grains, and an improvement in gluten deformation rate to group 1 with the accumulation of minerals.
