Abstract

This article presents the results of a study on the effect of planting dates and plant density on the growth and development of the medicinal plant Stevia rebaudiana. The research was conducted under irrigated gray soil conditions of the Fergana region. Three planting dates (April 1–15, April 15–30, and May 1–15) and two plant densities (83,000 and 111,000 plants per hectare) were evaluated. The results showed that early planting (April 1–15) with a spacing of 60×20 cm (83,000 plants/ha) ensured higher main stem height and better vegetative growth. Increased plant density reduced the feeding area and negatively affected plant growth. The findings highlight the importance of optimizing agronomic practices for successful stevia cultivation under irrigated conditions.
