Abstract

in the article, the results of the research carried out in order tostudy the influence of the time of planting and the area of feeding theseedlings on the biometric parameters of the leek (Allium porrum) plant arepresented with a deep scientific analysis. Planting was done by hand in 4x1cm rows in 7x40x60 cm boxes in the greenhouse on February 20, March10, and April 1. Seedlings appeared after 10-12 days, on May 1 they weretransplanted to open field. With this, 70, 50, 30 days of seedlings wereprovided. Planting in open field was carried out in a scheme of 50x10 cm.Harvesting took place on September 1-5. Morpho-biometric indicatorsinclude determining the main quality indicators of seedlings beforeplanting in open field: plant weight, false stem diameter, plant height andnumber of leaves. In each replicate, 10 of the most typical continuouslyrecorded plants were identified, excluding plants from the soil. Thefollowing indicators were determined for these plants: plant height, falsestem diameter, number of leaves. Plant height was measured from thebottom of the leaves to the tip. At the end of the research, the data analysisshows that the effect of the feeding area of the seedlings during thegrowing season on the above-ground mass of the plant was the sameduring all planting periods. Over the entire growing season, leek plantsgrown with the largest feeding area had a higher above-ground mass thanthose with the smallest seedling feeding area.
