Abstract : This examination aims to determinate influence of fertilizers toward  weed infestation, morphological and productive traits of different  alternative small grains, as well as to examine the correlation of the  studied traits of alternative small grains with weed infestation in  organic production. The field experiment was conducted on luvic  chernozem in completely randomized blocks, repeatad four times, in  the three year period insert ignore into journalissuearticles values(2013/2014-2015/2016);. Examination was  carried out on one winter cultivars of naked barley, spelt, durum,  compactum wheat and triticale, and the experiment included  fertilization with microbiological fertilizer insert ignore into journalissuearticles values(5.0 L ha-1); as well as the  combined application of microbiological insert ignore into journalissuearticles values(5.0 L ha-1); and organic  fertilizer insert ignore into journalissuearticles values(3.0 t ha-1);. Results obtained pointed out that examined  factors have important influence toward number and the dry weed  weight, but the influence toward diversity weeds is negligible. The  smallest the total number of weeds insert ignore into journalissuearticles values(12.7 plants m-2);, as well as the  dry weight of weeds insert ignore into journalissuearticles values(18.5 g m-2); was noted in the spelt insert ignore into journalissuearticles values(P˂0.01);.  The considerably significant smaller the total number of weeds on  the variant F2 insert ignore into journalissuearticles values(14.7 plants m-2); compared to F1 insert ignore into journalissuearticles values(15.4 plants m-2); and  F0 insert ignore into journalissuearticles values(15.5 plants m-2);, while dry weed weight on the variants F1 insert ignore into journalissuearticles values(23.7  g m-2); and F2 insert ignore into journalissuearticles values(23.8 g m-2); significant higher comparing to control F0  insert ignore into journalissuearticles values(20.7 g m-2);. The use of fertilizers have significatly influenced the  increase of the stem height insert ignore into journalissuearticles values(5.5-10.0%);, spike length insert ignore into journalissuearticles values(6.4-9.9%);,  weight of the plant insert ignore into journalissuearticles values(9.5-20.8%); and the weight of grains in the spike  insert ignore into journalissuearticles values(7.8-16.9%);. The negative dependence of the weeds number  insert ignore into journalissuearticles values(r= -0.69); and its dry weight insert ignore into journalissuearticles values(r= -0.39); relаted to the height of  stem, and, also, negative dependence between weight of grains in  the spike with the weed number insert ignore into journalissuearticles values(r= -0.32); has been perceived.  These results of examination showed that proper selection of the  genotypes with the application of fertilisers could have a significant  effect on the weeds in the organic production alternative small  grains.
