Effects of organical and conventional growing on the content of biologically active compounds of potatoes

It was determined that amounts of chlorogenic acid, tyrosine, and tryptophan in potato tubers depend on meteorological conditions, farming type, individual properties of a variety, and interaction of these factors (Pu003c0.05). It was noted in 2011 that organically grown potato tubers accumulated significantly higher amounts of chlorogenic acid, tyrosine, and tryptophan derivatives than conventionally grown tubers, while in 2012 the opposite was observed (Pu003c0.01). Such results are due to the different meteorological conditions during the survey years.
