Effects of Forecrop, Sowing Rate and Fertilization Upon the Technologie Properties of Spring Barley.Peer-reviewed article

Š OČKAY

Effects of several factors, viz.: kind of forecrop, sowing rate, fertilizing rate and weather conditions, upon the technologic properties of spring barley were studied in a series thoroughly prepared polyfactorial field trials. The study covers two forecrops, viz. winter wheat and malze grown as a silage crop, sowing rates giving 3,5; 4,0 and 4,5 milion germinating corns per 1 hectar and varios amounts of fertilizers. Regardles of their total amount the shares of main components were always constantand proportion was N : P : K = 1,0 : 0,63 : 2,07 ( N = N₀ and N₄₀). A new variety of spring barley, viz Koral HE-748, was chosen for trials. The results show, that the most important factor are weather and other conditions in individual years. Under given agronomic and ecologic contitions, typical for maize belt, better properties has barley grown after winter wheat, but only in dry years. Higher density of plants has no marked negative effects. If the sowing rate exceeds 4 milionn of germinating corns per 1 ha, the percentage of albumins is lower, whereas the proportions of starch and extract are higher. More intensive fertilization (N₄₀ + PK) has no negative effects. Provided that correct agronomic measures have been taken, factors bearing upon the technologic properties of spring barley can be arranged as follows: conditions in growing period, forecrop, fertilization etc.
