Relation Between the Yield of spring Barley and Protein Content in Its Corns.Peer-reviewed article

Š OČKAY

In 1973 -1975 aseries of field tests was carried out to study the effects of spring barley yields upon the protein percentage in its corns. All tests were limited to one of the maize growing regions with medium heavy brown soil with neutral reaction, medium high content of absorbable P and low concentracion of absorbable K. Four different varieties of barley were selected, sown silage maize, maintaining the seeding rate of 4,5 million germinating seeds per1 haand fertilized as follows : N ( basic component ) - 0, 50, 75 and100 kgper1 ha, other fertillizers in  a constant proportion to N, i. e. N : P : K = 1 : 0,63 : 1,66. No significant relation could be found be between the dry matter amount produced by yield and protein content in corns. The values of correlation coefficients depend on such factors as variety of barley, year of harvest and amount of applied fertilizers. Average values covering several years tend to equalization, which holds true both to slight, insignificant relations and marked ones. The properties of individual varieties seem to be decisive.
