The biggest total and marketable carrot
root-crop yields were obtained applying fertilizer with nitrification inhibitor Total yield in comparison with the yield
of carrots grown without fertilizers increased 10.3 t ha-1, or 17.2 %; the marketable
one – 7.5 t ha-1, or 17.8 %, but the output of marketable yield in comparison with this of
carrots grown without fertilizers increased only slightly, and because of the fertilizing
with Cropcare 10 10 20 and monomial fertilizers – even decreased (Fig. 4). Probably
rather rich in nutrients soil guaranteed suitable nutrition conditions, ant the application
of fertilizers increased only non-marketable yield.
