| Abstract | ||
| This experience was carried out in a private nursery in the city of Baquba, Diyala governorate for the period from 24th Fab. 2013 to 1st .Dec. 2013 to study the effect of humic acid spray on Cleopatra mandarin(Citrus reshni) seedlings tolerance to irrigation water. Seedlings treated with three salinity levels of irrigation water (ECw= 0.7, 3.0, 4.5 ds m-1), and two levels of Humic acid (0 and 1 %). The results can be summarized as follow: The increase in the level of salinity of irrigation water caused a significant decrease in seedlings growth through lower values of most studied growth parameters ,whereas it caused an increase in leaves Proline, sodium and chloride content. Spraying of humic acid on vegetative system led to improve of vegetative growth parameters and leaves content of chlorophyll, phosphorus and potassium whereas this application caused a decrease in leaves proline, sodium and chloride content. | ||
