Effects of nitrogen fertilization and pesticides on spring barley yield
1998
Kubinec, S. (Vykumny Ustav Rastlinnej Vyroby, Bratislava (Slovak Republic))
The effects of four levels of N nutrition (non-fertilized control, 30, 60 + 30 kg.ha-1, according to inorganic N content in the soil) and the effects of four levels of pesticide treatment (untreated control, herbicides, insecticides, as required herbicides, insecticides, fungicides) on the stand height, grain yield, 1000 grain weight (TGW) and the share of grains on sieves with the mesh of 2.2, 2.5, and 2.8 mm in two varieties of spring barley (Jubilant, Garant) were evaluated. N fertilization influenced positively the stand height and also the achieved yields. The yield with N fertilization according to inorganic N in the soil 7.25 t.ha-1 was insignificantly higher than that with N rate of 90 kg.ha-1. With pesticides, complete treatment by herbicides, insecticides, and fungicides ensured the highest mean yield of 7.42 t.ha-1, significantly higher than the yields in other variants.
