Abstract:
In order to establish the influence of different nitrogen, phosphorus and potassium fertilizers rates as well as of their
interaction on wheat flour there was set up an experiment in 2011 where there were applied several fertilizer rates with the
wheat crop on the cambic baticalcaric chernozem from A.R.D.S. Caracal, District Olt. There were determined the following
indicators: wet gluten, falling number, Zeleny sedimentation test, gluten formation index, glutemic index, pharinograph test
and alveograph test. This way, the wet gluten content has determined to the obtaining of values that show a flour of good
quality when moderate rates of nitrogen (N100 – N150) along with moderate rates of phosphorus, reaching 24.8-25.3% wet
gluten. The same way, the other quality indicators of the wheat flour as Zeleny sedimentation test has recorded values of
61-63 ml, the falling number of 234-244 second and the pharinograph and alveograph tests have conducted to obtaining of
flour of good quality when rates of N100-N150P80 were applied. So, after determining these indicators there was
established that the best quality of flour was given by moderate rates of nitrogen, N100 – N150 on moderate rates of
phosphorus, P80. The applying of nitrogen, phosphorus and potassium fertilizers alone does not ensure a proper quality of
the flour.
