Abstract
The experiment was carried out at the field of During the growing season of 2010 – 2011. The aim was to study the effect of humic acid with threes concentration (0, 2.5 and 5 ml/litter) and two transplanting container size (7 , 10 cm) and the interaction treatments growth , quantity and quality yield of cabbage, The experiment design was arranged according to R.C.B.D with three replicates The results showed that adding humic acid with 5 ml/Litter caused significant increase in the growth parameters (the number of external leaves,chlorophyll percentage , leaf area , the Fresh weight for external and internal leaf , the percentage of dry matter for internal leaves). Meanwhile the big size of transplanting container caused a significant increase in the percentage of dry matter in the external leaves. The interaction treatment between the addition of humic acid with 5 ml/Litter and the big transplanting container size caused the best growth in the leaves , roots and added the highest production 34.23 T/hea.
