The results of the treatment of half of the fertilizer recommendation in combination with the third level of organic fertilizer and bio-fertilizer gave results that do not differ significantly from the treatment of the full fertilizer recommendation in the above triple interference in soil and plant characteristics (IAA, average plant height), and this indicates the importance of the role of organic and biological fertilizers in Minimize mineral fertilizers.
