Primerjava različnih novejših načinov dognojevanja koruze (Zea mays L.) z dušikom : diplomska naloga = Comparison of several new ways of maize sidedressing (Zea mays L.) with nitrogen : graduation thesisŠkerbot, IgorNa Pragerskem smo v letu 1994 in 1995 postavili gnojilni poskus s koruzo (Zea mays L.) kultivarja 'helga'. V poskusu smo primerjalno preiskušali novejše metode za določanje potreb koruze po ... dognojevanju z dušikom (N) v razvojnem stadiju 7-9 listov koruze. Preverjali smo naslednje metode: Nmin metodo, hitri talni in hitri rastlinski nitratni test. V okviru poskusne parcele velike 1000m2 smo v obeh letih postavili 7 različnih variant dognojevanja z N v 4 ponovitvah. Glede na pričakovan pridelek koruznega zrnja (10 do 12 t/ha) smo ob osnovnem gnojenju s 30 m3/ha goveje gnojevke in s 30 do 40 kg N/ha ob setvi pri ciljni vrednosti 350 do 250 kg N/ha preverjali 1 manjši in 3 večje obroke N. Preučevali smo vpliv dognojevanja na pridelek suhega koruznega zrnjain zelene mase (t/ha) in na število rastlin in storžev na hektar. Osnovno gnojenje z gnojevko je dalo 10,6 t zrnja/ha (1994) oz. 12,4 t zrnja/ha (1995). Gnojenje z mineralnim N ob setvi je pridelek povečalo za približno 1 t zrnja/ha. Dognojevanje z N (od 25-125 in od 6-156 kg N/ha v obliki uree) ni dalo signifikantnih povečanj pridelka zrnja in zelene mase. To je pri vsebnosti Nmin v tleh pred dognojevanjem -304 kg/ha (1994) oz. 194 kg/ha (1995) lahko razumljivo. Enako majhen ali nikakršen vpliv se lahko pričakuje tudi glede na visoke vrednosti EUF-Norg (obe frakciji), ki je 3,15 mg/100 g tal. Nmin metoda in talni nitratni test dajeta podobne rezultate. Torej lahko tudi s pomočjo rastlinskega nitratnega testa in vsote obeh frakcij EUF-Norg, izboljšamo doziranje N za dognojevanje.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [I.
