Abstract

In order to evaluate the effect of barvar-2 phosphate biofertilizer and FOLIAR APPLICATION of micro nutrient on the yield and the yield components of grain CORN (Var. single cross 704), this experiment was carried out using factorial experiment design with two factors in effect based on randomized complete block design at three replications in Gharakandi village of chaipareh in 2010. In this experiment, the first factor (A) was in 3 levels: a1= barvar-2 phosphate + triple superphosphate, a2 = barvar-2 phosphate (inoculation of seed), and a3= triple superphosphate (soil application). The second factor (B) was in 5 levels: b1= B, b2= Zn, b3= Cu, and b4= Mn with FOLIAR APPLICATION of MICRONUTRIENTs, and b5= non FOLIAR APPLICATION of MICRONUTRIENTs. The results showed that plant height and number of grain row were affected by both of the factors. The effect of factor B especially Zn was significant on number of leaves, the number of grain in ears, ear diameter, straw yield, and biological yield, But the effect of factor A was not significant for this characters. The effect of barvar-2 phosphate was significant on grain depth in ear. The interaction of both the factors and the FOLIAR APPLICATION of micro nutrients had significant effect on grain yield and cob diameter. Totally the results showed that when the phosphates in the soil are in the average limit, this can increase the growth index and crop yield by dissolving a solution phosphates resources. The results of comparison showed that the barvar-2 phosphate biofertilizer was cost savings and reduced consumption phosphate fertilizer and the FOLIAR APPLICATION of micro nutrients because of Removing shortage their nutrition effect, increase the growth and adjusts development and finally improve yield and yield components. Highest grain yield was 15.89 t/ha in b2 treatment, and the lowest one was 12.7 t/ha in control treatment.
