The plant material taken for the study was collected from maize fields in Denmark. In total, maize cobs were collected from 58 fields of 15 farms (9 organic and 6 traditional ones). The plant material (97 samples) was divided according to the following criteria: maize cultivars, effective temperature sum (ETS) during growing period, type of farm (traditional and organic farms). The dry matter content of maize cob samples was determined as well as starch, neutral detergent fiber (NDF) and acid detergent fiber (ADF), phosphorus and magnesium content. The dry matter content was negatively correlated with NDF and ADF, but positively correlated with starch. A highly negative correlation of starch content with NDF and ADF was found.

Badania przeprowadzono w oparciu o kolby kukurydzy pobrane z pól rolników duńskich w roku 2001. Łącznie pobrano 97 prób, z 58 pól z 15 gospodarstw (9 ekologicznych i 6 tradycyjnych). Uzyskane wyniki przeanalizowano w zależności zróżnicowania odmianowego, sumy temperatur efektywnych oraz typu gospodarstwa. Zawartość suchej masy w kolbach w głównej mierze decydowała o zawartości skrobi, NDF, ADF, a także zawartości fosforu i magnezu. Zawartość suchej masy była ujemnie skorelowana z zawartością NDF i ADF, natomiast dodatnio z zawartością skrobi. Wysoka zawartość NDF i ADF w kolbach kukurydzy była ujemnie skorelowana z udziałem skrobi.
