Wykorzystanie biostymulatora Nano-Gro i międzyplonu ścierniskowego jako czynnika fitosanitarnego w monokulturowej uprawie pszenicy ozimej

Abstract

Summary One-factorial field experiment was conducted in 2010–2013. The aim of the study was to evaluate the usefulness of Nano-Gro biostimulant and stubble catch crop in reducing the occurrence of stem base diseases of winter wheat growing in continuous crop under traditional or reduced post-harvest and pre-sowing tillage and the influence of these factors on wheat productivity. The significantly higher infection of stems and roots of winter wheat growing in continuous crop as well as the decrease in grain yield by 12.3% were observed in relation to crop rotation. In plowing system the seed-dressing with Nano-Gro biostimulant and the combined use of that product with the annual plowing down stubble catch crop of white mustard significantly reduced the infection of stem base respectively by 28.7 and 21.9% compared with monoculture without regenerative practices. After tillage simplification stem base diseases reduction (by 17.5%) were found only after plowing down biomass of cat ch crop. The degree of the root system infection generally did not depend on tillage and regenerative practices but there was significant correlation between grain yield and index of root infection.
