Nano fe fertilizer dose and density effects on popcorn (ksc 604 p.c.) yield components

This research was conducted to determine the effects of Fe ferilizer application rates and density on grain yield and yield-related plant characteristics of popcorn in Arak, located at central part region of IRAN during 2011. The experiment was designed in a randomized complete block design with a split-plot arrangement with three replications. Fe doses of 0, 0.5, 1 and 2 mg 1000-1 were arranged in the main plots and density 6, 7.4, 8.8 and 10.2 plants m2 were considered as sub-plots.. Among the physiological parameters and analysis of net absorption was less affected by fe fertilizer. Absorption curve analysis showed a net decline during the growing season. The results showed that with increasing density, leaf area index, LAI durability and increased plant growth. The increased density reduces absorption was purified and analyzed. Increasing LAI increased light absorption in fieldIncrease photosynthetic capacity of plants that will eventually lead to increased performance. Much of the growth rate of density increase was related to increased leaf area index.
