Abstract:Pri gnojenju koruze se mora upoštevati količina mineraliziranega dušika (N-min) v tleh tako pred setvijo kot ob dognojevanju. Na njivi v Žitencah v občini Sveti Jurij v Slovenskih goricah je v poskusu, s štirimi obravnavanji (0 – kontrola, 20 + 30 kg N ha-1, 40 + 60 kg N ha-1 in 70 + 80 kg N ha-1 ob setvi in ob dognojevanju v istem zaporedju) analiziran vpliv odmerkov dušika na vsebnost klorofila v listih, silažno maso ter pridelek zrnja. Pridelek zrnja je največji pri odmerku 40 kg N ha-1 ob setvi in 70 kg N ha-1 pri dognojevanju v fazi BBCH 17/19. Vrednost klorofilmerskega odčitka je v fazi BBCH 7 – 9 pri kontroli 501, pri 70 kg N ha-1 pa 610. Korelacijski koeficient med klorofilmerskimi odčitki in pridelkom zrnja kaže 80 odstotno povezanost in čvrsto korelirata.

Title:Suitability of chlorophyll meter readings for top dressing in maize
Abstract:On the field in Žitence, Sveti Jurij v Slovenskih Goricah, a field trial with four treatments; 0 – control, 20 +30 kg N ha-1, 40 + 60 kg N ha-1 and 70 + 80 kg N ha-1, before sowing + top dressing at stage 7-9 leaves respectively was done. The effects of nitrogen rates on chlorophyll readings in leaves, silage mass and grain yield were analysed. Grain yield was the significantly highest at 40 kg N ha-1 at sowing time and 60 kg N ha-1 added at BBCH 7-9 stage. Chlorophyll readings in the control treatment were 501, and at the rate 60 kg N ha-1 610. Correlation coefficient between chlorophyll meter readings and yield is showing 80 % correlation, which means strong connection.
