The effect of adding nitrogen and potassium to the soil and spraying on the accumulation Dry matter and nitrogen concentrations in shoots of wheat plant Triticum aestivum L

Abstract

A field experiment was conducted in Ershadiyeh in a sedimentary soil with a mixture of clay and silty texture in
the winter season. 2005-2004 to determine the best concentration of nitrogen and potassium to spray on
The vegetation of the wheat plant, cultivar Ibaa 95 - in the two stages of inflorescence and flowering and complementary
of fertilization and their effect on dry matter accumulation and the percentage distribution of nitrogen concentration.

in the shoot of wheat plants.
A factorial experiment was carried out with a completely randomized block design, RCBD, which included four
The concentration of nitrogen is 6000, 5000, 4000, 0} mg N.L-1 in the form of urea fertilizer
(N% 46) {, and the four concentrations of potassium are 0, 500, 1000, 1500} mg K.L-1 in a form
Potassium sulphate fertilizer {(K% 41.50) in addition to the traditional addition treatment to the soil
And three microt. The results showed the superiority of foliar feeding with nitrogen and potassium fertilizers.
Significantly increased the accumulation of dry matter and the percentage of nitrogen concentration in the total

The vegetative growth of wheat compared to the treatment of conventional addition to the soil.
