Abstract

In this article, the effectiveness of various phosphorus fertilizers in the cultivation of white cabbage under the conditions of typical gray soils in the Samarkand region is studied. The application of different phosphorus fertilizers against the background of N180K90 improved the growth and development of white cabbage. The plant height was 2.0–3.4 cm higher compared to the control variant, and the cabbage head mass was 0.74–0.78 kg heavier. The use of various phosphorus fertilizers also had a positive effect on the yield structure of the cabbage head. It is noted that under these soil conditions, the use of PS-agro fertilizer is more effective than ammophos fertilizer.
