We aimed to develop liquid nitrogen fertilizers containing ferrocene and test them in 
practice. To do this, we synthesized water-soluble salts of p-ferrocenphenol and p, m-ferrocenyl 
benzoic acids. The reaction was carried out according to the following scheme:

Ferben-sodium 
We conventionally called them Ferphenol, Ferben-Potassium, Ferben-Sodium. 
We studied the effects of synthesized biologically active compounds in combination with 
KAS (urea-ammonium nitrate) on the growth and development of cotton and wheat plants, as 
well as on increasing productivity. 
The experiments were conducted in 2020 in the cotton fields of the farm "Khojaariqli 
Pakhlavon" in Markhamat district of Andijan region. SAKO was selected as a water standard as 
a control. For the experiment, variant 1 of water (control), variant 2 of Ferphenol, variant 3 of 
Ferben-potassium, variant 4 of Ferben-sodium, variant 5 of KAS, variant 6 of SAKO were 
selected.
