The influence of an organic and conventional systems on chemical composition of potato tubers
Apstrakt
The crude protein and protein, free amino acid and nitrate contents in potato tubers of five varieties growing in organic and conventional crop management systems were Studied in the field experiment. Field trials were carried out on two localities of different altitude and soil conditions. Mean content of crude protein was significantly higher in tubers from organic crop management than in tubers from conventional system ( 11.02 and 9.83 % in dry matter, respectively). Similar result was observed in protein content (in organic 5.51 % and in conventional 5.08 % in dry matter, respectively). Variety was the factor having the highest direct effect on crude protein as well as protein contents. Tubers from conventional crop management showed an increased tendency to accumulate nitrates.
