ARTICLE ANNOTATION

quote
This article describes the effect of plant topping timing on the cotton weight per boll in cotton varieties Ravnaq-1 and UzPITI-103, depending on plant density and the timing of thinning operations. The study found that chemical plant topping is optimal when thinning is carried out at the stage of 1–2 true leaves, maintaining a plant density of 80–90 thousand plants per hectare.
