As opposed to direct sowing, production of seedlings of vegetable crops for .ting is commonly practiced by vegetable growers. This study was undertaken to determine the effects of humic acid on the growth and the macro and micro contents in tomato (Lycopersicon esculentum) and eggplant (Solanum melongena var. esculentum) seedlings under greenhouse conditions. Different levels of :humanic acid (50, 100, 150, 200 ml 1-1) were applied to growing media (peat) after transplanting of examined seedlings of the species every ten days by the time of planting.The highest growth rate for leaf stem and root growth were obtained at 50 and l00 ml-1 HA and 50, 100, 150 ml 1-1 HA for tomato and eggplant seedlings, :Y as compared to the control.. The highest content of macro and micronutrient contens were obtained at 100 ml 1-1 HA and 200 ml l-1 HA for tomato and eggplantseedlings, respectively as compared to the control.

Wpływ różnych stężeń kwasu huminowego na wzrost siewek pomidora i oberżyny oraz ich skład chemiczny W niniejszej pracy podjęto próbę określenia wpływu kwasu huminowego (HA) na wzrost siewek oraz zawartość makro- i mikroelementów w siewkach pomidora (Lycopersicon esculentum L.) i oberżyny (Solanum melongena L. var. esculentum) w warunkach szklarniowych. Stosowano 50, 100, 150 i 200 ml 1-1 HA do podłoża (torf) co 10 dni od czasu przesadzenia siewek. Najlepsze wyniki w zakresie wzrostu liści, pędów i korzeni otrzymano po użyciu stężeń 50 i 100 ml l-1 HA w przypadku pomidora oraz 50, 100 i 150 ml 1-1 HA w przypadku oberżyny. Najwyższą zawartość makro- i mikroelementów stwierdzono w roślinach pomidora po zastosowaniu roztworu o stężeniu 100 ml l-1, a w roślinach oberżyny - 200 ml l-1 HA.
