| Summary: | Four levels of N, P and K nutrition (poor, moderate, satisfactory and high) and all their possible combinations
with 64 treatments in two replications (128 plots) were studied in a long term field trial on barley yield and
malting quality. A standard East-European spring barley "Opal" (bred in Czechoslovakia) was grown in 1986,
13th year of the agricultural experiment, involving various crops in previous years, on a calcareous loamy
chernozem soil. The optimum fertility levels for yield enhancement resulted in the poorest malting quality: low
modification and extract but long saccharification time and high protein. To solve this problem the brewing
industry will have to apply the well-known technological methods available since growers are not likely to give
up their fertilizers. Applying soil and plant analysis data, having knowledge about both soil and plant optimum
values, the danger of the excessive use of fertilizers can be realized and decreased. |
