Abstract

The investigation into winter and spring barley production in correlation with the brewing quality and yield of grains in the Republic of Croatia from 1970 to 2002 was carried out. The regression analysis of yield of kernels using the data from the State Institute for Statistics, Croatia, shows for this period the annual yield increase by 52 kg/hectare. The yield analysis from the trials at the Osijek Institute of Agriculture with the prevailing varieties in specific five-year periods in the large scale production, an annual increase by 94 kg/hectare/year in winter barley and by 26 kg/hectare in spring barley was found.
The quality analysis in the Republic of Croatia of the period from 1970 to 2002 showed that, in total, the extract content was 79.19%, the extract difference 2.49%, mass portion of proteins in malt 12.53%, Kolbach index 41.12%, Hartong 42.36%, viscosity cp 8.6 1.549 mPas and diastatic power 309 U.WK. When comparing the malt quality in winter and spring barley varieties it was noticed that on average the spring barley varieties vs. the winter barley varieties had a higher and more unfavorable protein content in malt, but lower viscosity and greater diastatic malt power.
In production of winter barley and in investigated thirty year period the most important varieties were Mursa, Alpha, Pan, Robur, Sladoran, Plaisant, Rex, Angora, Zlatko, Lord, Barun and in production of spring barley varieties Union, Velebit, Berenice, Jaran, Gimpel, Astor, Scarlett.
