IMPACT OF FOLIAR FERTILISATION OF PLANT ON THE CONTENT OF MACROELEMENTS IN POTATO
Elzbieta Boliglowa, Stanislaw Dzienia
The 1990-1992 research investigated the impact of foliar fertilisation on the chemical composition of potato leaves, stems, stolons and tubers over flowering. It was observed that neither foliar fertilisation with a 6% of aqueous solution of carbamide and a multi-component fertiliser (Agrosol - K) nor solid fertilisation caused significant differences in the contents of N, P, K, Ca, Mg in respective potato plant parts. During the flowering period the most equivalent K : (Ca + Mg) ratios were found in stem.
Key words: potato, foliar fertilisation, content of microelements.
