THE EFFECT OF NITROGEN, MAGNESIUM AND IRON APPLICATIONS ON THE NUTRIENT CONTENT OF PARSLEY (Petroselinum crispum)

The aim of this study is to investigate the effects different rates N, Mg and Fe applications on mineral content parsley leaves. experiment was carried out in a greenhouse according randomized plot design with three replications. Seven dose treatments were designed as 130, 160, 190, 220, 250, 280 310 kg per ha N ammonium nitrate (33% N), 40, 80, 120, 200, 240 magnesium sulphate (16% MgO) 8, 16, 24, 32, 48 56 ferrous (20% Fe). did not significantly affect phosphorus concentrations nitrogen uptake plant increased all element highest K Ca values determined fertilizer applications. amount leaves also depending increasing rates. results indicate that most effective nutrition fertilizers doses up increase above permissible level.
