Desislava Todorova, Нriska Boteva

Abstract: Biological efficiency of organic poultry manure in head cabbage for later field production was investigated during the period 2010 – 2013 in the Institute of Agriculture, Kyustendil. As a result, the diameter of the heads cabbages increases compared with non fertilized control with 2.3 and 3.0% in varieties
Balkan and Pazardjishko podobreno. In variety Balkan organic fertilization induces increasing yields by 13.6%, while the increase in Pazardjishko podobreno was only 2%. The results аbout vitamin C content are diverging, with a low increase in values has Balkan and a significant reduction in Pazardjishko
podobreno (15.4%). The dry matter content ranged from 10.8 to 11.1%.
