Effect of planting time and seedling feeding area on the yield and biochemical composition of leek (Allium porrum L.)

Abstract

In the article, the results of the research carried out in order to study the effect of planting time and feeding area on the biochemical composition of leek (Allium porrum L.) are presented with an in-depth scientific analysis. Planting was done by hand in 4x1 cm rows in 7x40x60 cm boxes in the greenhouse on February 20, March 10, and April 1. Seedlings appeared after 10-12 days, on May 1 they were transplanted to open ground. This ensured that the seedlings were 70, 50, and 30 days old. Planting in open ground was carried out in a scheme of 50x10 cm. Harvesting took place on September 1-5. At the end of the research, the data analysis shows that by evaluating the nature of growth of false stem diameter in leek onion plants at different planting periods during the growing season, it can be noted that the feeding area for seedlings is larger and the seedlings when planted early, standard products had earlier maturity and higher product quality.
