The current study goal is to determine the influence of some organic fertilizers over the growth and the productive qualities of the glasshouse cucmbers grown as a substrate culture. The experimental work was conducted in non-heated glasshouse Venlo type in Maritza VCRI Plovdiv with Defense cucumber variety (EZ). Adding Humustim to the nutrition regime of the glasshouse cucumbers increases the first quality production (99550 kg/ha).The quantity of the yield from second quality was not influenced by the use of the studied fertilizing bioproducts. The treatment with Humustim did not significantly increase the total yield in comparison with the conventional fertilization but there was considerable higher influence over the productivity among the rest of the fertilizing bioproducts. As a result of adding the organic fertilizers to the nutrition regime the percentage distribution of the production from first quality was not increased.
