YIELD AND QUALITY OF LEEKS AS AFFECTED BY METHOD OF GROWING

The research was carried out in 2005 at the Lithuanian University of Agriculture, Department of Horticulture. The aim of research was to investigate the yield and quality of different leeks cultivars as influenced by different grown methods. Leeks were growing in these ways: I way – growing in smooth surface; 2 way – growing into 15 cm deep furrows; 3 way - growing on the 15 cm furrows; 4 way – growing in the holes of 20 cm depth. The biggest harvest has been received from the early leek varieties, total harvest - 36,63 t ha-1, standard harvest – 31,12 t ha-1 and late leek varieties total harvest - 26,85 t ha-1, standard harvest – 24,05 t ha-1) grown in smooth surface. The early leeks grown in the holes of 20 cm depth has been received the biggest mass per plant (average 325,0 g) and mass per plant of the late leeks has been received from the leeks grown on the 15 cm furrows (average 274,7 g). The early leeks of the best biochemical composition have been grown in the holes of 20 cm depth and the late leeks have been grown on the 15 cm furrows.Žemės ūkio akademijaVytauto Didžiojo universiteta
