Comparison of Variable Rate Application and Uniform Distribution of Fertilization on the Yield of Forage maize
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 4
Abstract
The purpose of this research is that we compare quantity used chemical fertilizer on forage corn in two ways, variable rate application and uniform distribution. Therefore we chose two tract of land. They were 1000 square meter and each of tracts had divided to 40 cells that they had dimensions of 5×5. We made between all of the cells, the first tract to determine quantity of azote, phosphorus, potassium and from the other tract, we chose sample five random. In first tract, proportional distributed fertilize on the basis of soil test and the table of fertilize recommendation and need of each cells. In other tract, distribution of fertilize on the basis of total taking area. Consideration results of the compare mean test the use of fertilize urea, supper triple phosphate and potassium sulfate was lesser in the way of proportional distributing toward the uniform distribution the numbers were in order %30 , %45.5 and %40 that they represented meaningful difference in level of %99. Although average of yield of dry substance in VRA 430 kg/ha was more toward the other way, but it didn’t show meaningful difference in level of %95. But difference of yield of corn, seed and protein were meaningful in the VRT toward the other one in level of %95 and they were in order 0.890 , 0.140, 0.06 kg/ha.

Effect of salicylic acid on yield and yield component of grapevine (Vitis vinifera) under salinity stress condition
Salinity is one of the limiting factors in agricultural production. Salicylic acid, as a plant growth regulator, is able to increase the salt tolerance of crops. Therefore, the effects of salicylic acid on quantitative...
