Abstract
In order to investigate effect of nano potassium and nano silicon and nitrogen rate in two rice cultivars, an experiment was carried out as split factorial in randomized complete blocks design with three replications at Sari, Iran in 2013 and 2014. Rice cultivars were chosen as main plots including Tarom Mahalli and Tarom Hashemi. Nitrogen rates 34 and 69 kg N ha–1 and nitroxin with nano-particle including nano-potassium, nano-silicon and control treatment chosen as sub plot. The results indicated the most panicle length and plant height had obtained for Tarom Hashemi cultivar. Third and fourth internode bending moment in Tarom Hashemi was more than Tarom Mahalli. Fourth internode breaking resistance for Tarom Hashemi equal to 6.55% was more than Tarom Mahalli. But third internode bending moment was less. The highest fourth internode bending moment in both years was obtained with nanosilicon application. In both years third and fourth internode lodging index in Tarom Hashemi was more than Tarom Mahalli. With nano potassium using in first year the highest internodes lodging index was observed with nano potassium consumption. For Tarom Hashemi the highest third internode breaking resistance was obtained with nitroxin application.
