Ocena zdolności kiełkowania nasion oraz wybranych parametrów biometrycznych (długość oraz sucha masa korzeni i koleoptyla) słonecznika zwyczajnego (Helianthus annuus) po zastosowaniu preparatów zawierających efektywne mikroorganizmy (EM)
Seed germination and early growth microbiotest PhytotoxkitTM was used in the
experiment, which consisted of 3 independent laboratory experimental series with
one month intervals each and 3 replications. The aim of this study was to evaluate
germination dynamics and capacity as well as selected biometric parameters after
seed treatment with two preparations containing effective microorganisms: EM
Farma (EMF) and EM Farma Plus (EMFP). Sunflower seeds (H. annuus) were
chosen as the experimental material. Seeds soaked in distilled water were control
objects (K) in these experiment. Apart from control (K), reference material was
prepared in the form of two biostimulants: Kelpak SL (KSL) and gibberellic acid
(GA3). The effect of the two biopreparations EM Farma (EMF) and EM Farma Plus
(EMFP) was beneficial related to germination capacity and biometric parameters of
sunflower (H. annuus).Doświadczenie przeprowadzono z użyciem mikrobiotestu kiełkowania i wczesnego
wzrostu roślin – PhytotoxkitTM. Testy obejmowały 3 niezależne serie doświadczeń
laboratoryjnych w odstępach miesięcznych po 3 powtórzenia. Celem doświadczenia
była ocena dynamiki i zdolności kiełkowania oraz wybranych parametrów
biometrycznych nasion po zastosowaniu dwóch preparatów zawierających efektywne
mikroorganizmy: EM Farma (EMF) oraz EM Farma Plus (EMFP). Materiałem do
badań były nasiona słonecznika zwyczajnego (H. annuus). Obiekt kontrolny (K)
stanowiły nasiona, moczone jedynie w wodzie destylowanej. W doświadczeniu
oprócz kontroli absolutnej (K), zastosowano również jako obiekty porównawcze dwa
biostymulatory: Kelpak SL (KSL) oraz kw. giberelinowy (GA3). W przeprowadzonym
doświadczeniu stwierdzono korzystny wpływ zastosowanych biopreparatów EM
Farma (EMF) i EM Farma Plus (EMFP), związany z polepszeniem dynamiki
kiełkowania oraz wybranych parametrów biometrycznych słonecznika zwyczajnego
(H. annuus)
The effect of the type of preparation on the deposit of copper while spraying the winter oilseed rape
The aim of the research was to determine the copper deposit volume on winter oilseed rape in three development phase (according to the BBCH scale: 12, 14 and 16). The experiment was performed in triplicate at the spraying speed of 0.86 m s-1. Two working fluids were used: foliar fertilizer Mikrovit Copper 80 and a nanocopper preparation, at the dose of 160 g Cu ha-1. The deposition treatment of the plants was conducted in the spraying chamber ‘Aporo1’ at two pressures (0.20 and 0.28 MPa), using two different types of flat fan nozzles. The dried rape plants were mineralized, and then, in order to determine the deposit, the Cu element concentration was measured using the spectrometer. The largest deposit of copper was obtained using the foliar fertilizer Mikrovit Copper 80 and using a double flat fan nozzle DF 120-02. The statistical analysis of the results of the study showed a significant effect of the type of liquid used on the value of copper deposit on winter oilseed rape plants
