Abstract: Details of the field experiments which were carried out in the Kazliskiai organic farm from 1999-2001 were needed for our investigations. The integrated evaluation method enabled us to make complex evaluation of the influence of catch crops (red clover, common ryegrass, white mustard and winter rape) for green manure and animal manure on spring barley agrocenosis in organic farming. The variances of the 11 indicators were subdivided into scales of 9 points. The resulting evaluation points were marked in a network diagram. The evaluation threshold, which is equal to 5 points, was also marked. The integrated evaluation index, consisting of the average of evaluation points, its standard deviation and standard deviation of the average of evaluation points which are below the evaluation threshold, was calculated. The influence of red clover for green manure on barley agrocenosis, according to the calculated integrated evaluation indices, is stronger than that of other catch crops and manure
