Effect of nano titanium oxide, nano zinc and multiwall carbon nano tube on yield and yield components of green gram was carried out in Kohkiloyeh-Boyrahmad province, Iran with 30 degrees 45' N and 50 degrees 44' in 2013 growing seasons. The experiment was arranged as factorial in a completely randomize block design with three replications, treatments including: four concentrations (zero, 50, 100 and 200 mg/l) of above nano particles, were spraying on green gram plants at 4-2 leaf, 8-6 leaf stages and pod stage. The results showed all of nano particle treatments had significant effect on some yield components of green gram plants. Concentrations of multiple carbon nano tube at 50, 100 and 200 mg/l had significant effect on number of pod/plant, seed thousand weight and biological yield, also nano titanium oxide at 50 mg/l had positive effect on grain yield. The harvest index, the number of grain/pod and seed protein percent was higher under 50 and 200 mg/l of nano zinc treatments. In conclusion, the spraying of 50 mg/l of above nano particles had the highest effect on yield and its components of green gram.
