Response of wheat to urea and its relation to soil-plant test values (in Iraq)
1983
Mohammad, B.A.
In this study emphasis has been placed on soil collected from two different regions in Northern Iraq, and the use of different chemical and biological soil tests. The study intended also to a. investigate the pattern of NPK uptake during the various growth stages of the wheat variety (ARAS), b. to study the wheat response to urea fertilizer applications in two different soils, c. to evaluate the residual effect of urea fertilizer application on the growth and NPK uptake of the following crop (corn) d. to compare and correlate some soil test values in order to adopt them as parameters of soil fertility by comparing the values with growth characteristics of wheat plant grown in the two soils investigated
