| Abstract:
Field experiment was conducted in order to optimize production factors such as seed sowing date and type of plant cover in early leeks, grown for harvest in July. The best quality transplants and maximum marketable yield were obtained by sowings at the beginning of January. Similar effects were noted from sowing carried out two weeks later, while its further delay to February caused a significant reduction in yield. Early leeks planted in mid-April responded well for all types of covering used for 5 weeks from transplanting into the open field. Among the tested covers flat perforated plastic with 50 holes per 1 m2 appeared to be slightly more efficient, followed by a low plastic tunnel and Agryl P-17. | |
