摘要：It has become necessary to use various techniques in agriculture including nanotechnology techniques in agriculture. It is gaining interest as one of the promising approaches to increase crop production. It possesses all the characteristics needed to be used in agriculture such as high solubility, good efficiency and can be used in small quantities. This increases the efficiency of fertilizers and reduces the cost compared to conventional fertilizers. An experiment was conducted in pots in Plant Production Department at the Technical Agricultural College in Mosul of Iraq to study the effect of spraying with some nano practices fertilizer on the vegetative growth of broad bean (V icia ;fa b a L.). The experiment included five treatments (without fertiliza- tion,ZnO NPs 50 ppm and S NPs 50, 100 and 200 ppm) carried out in completely randomized design. Analysis of the data indicated that zinc nanomaterials (50ppm) and high concentration of sulfur nanomaterial (200ppm) caused significant increase in broad bean length, but without significant differences with sulfur concentrations of 50 and 100 pmm. Zinc nanomaterial at 50ppm concentration had an effect on the number of branches of broad bean). Only zinc nanomaterial (50ppm) had a significant effect on number of leaves compared with sulfur concentrations and the control. There were no significant differences with different treatments of sulfur and as well as control, except sulfur 200 ppm. The zinc nanomaterial had a significant effect on the area of broad bean leaves.
