ANALYSIS OF THE INFLUENCE OF SOME DOSES OF POTASSIUM AND NITROGEN ON NO. OF BRANCHES/PL. AND ON THE NUMBER OF PODS/PL. ON THE ARHITECT RAPESEED HYBRID CROPED IN THE S-E AREA OF ROMANIA

Abstract

In the south-eastern area of Romania, the Arhitect rapeseed hybrid was tested, in order to determine its adaptability to the pedo-climatic conditions specific to this geographical area. In the present study, there were studied the influence of potassium and nitrogen on characters such as no. of branches./pl. and no. of pods/pl. Thus, related to no. of branches/pl., only a very high dose of potassium and, respectively, doses of 100 and 150 kg N a.s./ha. value significantly influence this character. Related to the number of pods/plant, this character is influenced significantly in value especially by the increase in the nitrogen dose and less by the potassium dose.
Also related to the variation of the correlation coefficient between the no. of brnches/pl. and of no. of pods/plant depending on the with potassium and nitrogen fertilizing level, the highest values of this index were calculated especially for the highest doses of nitrogen.
