Hof Forecrops Beer Upon the Quality of Malting Barley.Peer-reviewed article

Š OČKAY

Through a number of very exact polyfactorial field trials the author has studied the effects  of two forecrops, i. e. of silage maize and winter wheat, upon some important mechanical and chemical properties of spring malting barley. Ears on principal stems and on offshoots were evaluated separately by applying the following criteria: effects of forecrop upon the uniformity of corns, proportion of ear number on offshoots to that on pincipal stems, average weight of 1000 corns and contet of protein in dry matter of corns. Spring barley grown after silage maize was better than that preceded by winter wheat. No diference was found in protein percentage between the ears on principal stems and on offshoot ones. Winter wheat as aforecrop is in this respect less favourable. The protein content in ears from mein stems was 3,5%, i. e. by 0,47% higher than in ears on offshoots. Forecropt has very marked effects  upon  the total protein content the values for barley after silage maize being better . The difference amounts to - 11.3% and - 8,2%. For barley after silage maize strong negative correlation was found between the total yield and protein content, whereas for barley having winter wheat as a forecrop negative coorelation was insignificant.
