Relation between nitrogen nutrition index and production of spring malting barley

Original language description

Although the nitrogen nutrition index (NNI) is a widely used indicator of plant nitrogen status, no model of NNI calculation for spring barley (Hordeum vulgare) reflecting also specific malting requirements of grain has been published. The aim of this study was to determine an optimal range of the nitrogen nutrition index with respect to optimal grain protein content, plump grain yield and lodging of spring malting barley during 7-year (2007 - 2013) strict field experiments. The most suitable indicators for evaluation of the nitrogen concentration in shoot biomass of the spring malting barley in our experiments proved to be Justes et al.s model Nc = 5,35 DM(-0,442) designated for winter wheat and Zhaos model Nc = 4,76 DM(-0,39) designated for winter barley, where DM is shoot dry matter in t/ha. The nitrogen nutrition index for spring malting barley should not exceed a value of NNI = 0,80 and NNI = 0,90 using the Justes et al.s model and the Zhaos one during the BBCH 30 - 45 growth stages.
