Parallel coordinate plots of maize traits under different magnesium applications

摘要

The paral el coordinate plot is proposed as an efifcient tool for visualization of 13 traits of“stay-green”maize (Zea mays L.) cultivar exposed to different methods of magnesium application. The ifeld experiment was conducted in the Department of Agronomy, PoznańUniversity of Life Sciences, on the ifelds of the Department of Teaching and Experimental Station in Swadzim in 2006–2008. Experiment was conducted as a single-factor experiment with seven applications of magnesium in a randomized complete block design with four replicates. The highest mean values of grain yield and 1 000-grain weight were obtained after application of variant T3 of magnesium (10 kg MgO ha–1 soil) in the al three years of study.
