ABSTRACT

 

In our country there are controversies regarding the effect of the nitrogen fertilizers on vegetable bacterisation, on the two factors combinations for production increasing.

 In this context, in Arad ecological and agricultural area, during 1999-2002 period of time, the effect of nitrogen fertilization on the bacterisation found was studied by using Biotrofin as biological fertilizer.

The results that were obtained during the entire studied period impose doses of nitrogen fertilizer (30 kg s.a/ha) in combination with Biotrofin biofrtilizer applied to seeds (10 l/ha).
