Abstract
The aim of the work was to study the use of organic fertilizers on the growth and development of pepper culture. Work was carried out on the territory of the Guba district of Azerbaijan, on meadow–forest soils in 2027–2018. The compost Guba-Khachmaz was used. Pilot sites with various composting options were laid. As a result of the work, it was found that in the version of 20 t/ha of compost with every 100 centners of the crop, nitrogen — 36 kg, phosphorus — 13 kg, potassium — 42 kg are removed from the soil. In the control version, these indicators were respectively: 31, 10, 34 kg. In conclusion, it was concluded that the application of compost significantly affected the utilization of nutrients.

Summary
При этом изучали накопление питательных веществ в почве и качественные показатели под действием компоста. Перед внесением в почву органических удобрений брали пробы из компоста для определения содержания питательных элементов [2]. Обсуждение результатов При применении 20 т/га компоста значительно увеличивается количество доступных форм азота по сравнению с контрольным вариантом без удобрений. Содержание суммы доступных форм аммиачного и нитратного азота в почве в слое 0-20 см в варианте 20 т/га компоста составляло: в период бутонизации 20,8 мг/кг, в период цветения 22,5 мг/кг, в конце вегетации 27,5 мг/кг, в контрольном варианте эти показатели соответственно равнялись 30,0; 25,5 мг/кг; 17,5 мг/кг.
