A scientific article co-authored by Łukasz Domański (M.Sc.), a doctoral student from the Siedlce University Doctoral School in the discipline of agriculture and horticulture has been published in the Agronomy Science.
The aim of the study was to determine the effect of herbicides and biostimulants on the content of total nitrogen, protein nitrogen and total nitrogen uptake by tubers of three varieties of edible potato edible potatoes. The results were obtained from a three-year field experiment with the following factors:
I - three varieties of edible potato - Bartek, Gawin, Honorata; II - five ways of applying herbicides and biostimulants: 1 - control facility, 2 - mechanical-chemical treatments and Harrier 295 ZC herbicide, 3 - mechanical-chemical treatments and Harrier 295 ZC herbicide + Kelpak SL biostimulant at the end of plant emergence, 4 - mechanical-chemical treatments and Sencor 70 WG herbicide, 5 - mechanical-chemical treatments and Sencor 70 WG herbicide + Asahi SL biostimulant at the end of plant emergence. Total nitrogen content was determined in the dry weight of tubers using the Kjeldahl method. Significant effects of factors on the content of total nitrogen and protein nitrogen in tubers and on the uptake of total nitrogen by potato tubers were shown. The highest content of total and protein nitrogen was recorded in the tubers of the Bartek variety, and the highest nitrogen uptake was recorded with the yield of the Honorata variety.
