Summary: | Potassium (K) plays a significant role in preventing outbreaks of pathogenic infections and thereby maintains the photosynthetic leaf area, which supplies assimilates for grain filling. The aim of this research was to investigate the role of K in barley straw anatomy, plant stand architecture, and yield formation. Growth and yield of barley improved with increasing K application rates. This appeared to be due to increased number of spike-bearing tillers, number of grains per spike, and single-grain weight. Straw and walls of cuticle, epidermis, and sclerenchymatous cells thickened in relation to applied K. Thick and firm internodes as well as efficient use of resources resulting from K applications are among key features for good-quality crop production in the field. |
