YIELD AND MORPHOLOGICAL FEATURES OF LEEK (ALLIUM PORRUM L.) CULTIVATED IN THE TECTONIC FORELAND OF CRIMEA

key words: leek, date of sowing, cultivation density, yielding, morphological features

Summary:

The experiment carried out over 2010-2012 at the experimental field of Crimean Agrotechnological University in Simferopol, Ukraine (44°56'N, 34°06'E). It was investigated the effect of cultivation method (cultivation from seedlings and direct sowing to the ground) and the date of seeds sowing - direct to the ground (first 10-days of March, second 10-days of March, first 10-days of April) - for seedlings (second 10-days of February, first 10-days of March, second 10-days of March); distance between the plants in rows (20, 25 and 30 cm) on the morphological features and yield of leek ‘Sizokrył'. Leeks were grown in double rows spaced by 40 cm. Plants grown from seedlings were characterized by the better biometrics features than grown from seed sowing directly into the ground. Delaying the sowing date of seeds by 10 days at seedlings production (compared to control date i.e. first 10-days of March) influenced the most favourable on the biometrics features of the yield. In the leek cultivation from direct sowing to the ground the earliest date caused achieve the plants with the best parameters. Leeks cultivation in the distance of 25 cm in rows contributed to achieve plants with significantly the highest stalk diameter and the highest number of leaves. Increase the area per plant resulted in a significant increase in the width of the leaf blade. The correlation analysis of the results showed that the diameter of the stalk depends on the plant height, number of leaves and their width.
