Effects of N, B, Mn and Zn nutrients foliar application on some physiological characteristics of maize (Zea mays L.) in different growth stages

摘要

In order to investigate the Effects of N, B, Mn and Zn nutrients foliar application on some physiological characteristics of maize single cross 704 (Zea mays L.) in different growth stages an experiment was conducted in factorial form based on randomized complete block design (RCBD) with three replications at the Research Station of Saatlo, Urmia, north-western Iran, during growing seasons of 2013-2014. Treatments were five levels of foliar application include (N (Urea), Mn sulfate (MnSO4.H2O), Zn sulfate (Zn SO4), boric acid (H3BO3), control and three growth stages include (the 8-10 leaves stage, the tasseling stage and the grain-filling stage. The analysis of the data showed significant effect of interaction between growth stage and foliar application on 100-grain weight and number of grain at the probability level of 5 and 1% respectively. Also foliar application had significant effect on grain yield per plant (p
