Abstract
In order to study of magnetic field and nanosilver effects on fodder maize in comparison to micronutrients fertilizers, an experiment was conducted at research farm of Razavi Research and Technology Institute in the year 2007. This experiment was done with 7 treatments based on randomized complete block design with four replications. Treatments were including (T1) magnetic field and silver nano particles + Kemira fertilizer (T2) magnetic field and silver nano particles + Humax fertilizer (T3) magnetic field and silver nano particles (T4) Kemira fertilizer (T5) Librel fertilizer (T6) Humax fertilizer (T7) control (NPK). Results showed that fresh yield was the highest in (T3) and T4 treatments. These treatments increased the maize fresh yield 35 and 17.5 percent in comparison to control respectinely. Dry matter yield of exposed plants to magnetic field and silver nano particles was more than other treatments significantly. There was not significant effect on fresh weight of maize ear. Magnetic field and silver nano particles treatments (T3 and T1) showed the greatest ear percentage in plant and the lowest found in T7 and T5 treatments. It is seems that in T3 treatment, depletion of Ca, N and P of soil was greater than other treatments. Exposure to magnetic field and silver nano particles enhanced the crude protein and decreased ADF in silage resulting in increasing silage quality.
