Abstract
Humic acid has effect on seed germination in different plant species.
In general such effects include increasing the speed of germination; higher percentage of germination and an increase in root length during the initial stage of plant growth.
Monosodium glutamate waste water from factories (MGW) has some useful amino acids and mineral elements that may have useful effects on germination.
In this study, humic acid (0, 2500, and 5000 mg/L) and MGW (0, 100, and 200 dilution times) were evaluated their effect on germination, root length, shoot length and dry and fresh weight of root and shoot of onion, lettuce and tomato seeds.
Results showed that 2500 mg/L humic acid was better than 5000 mg/L and 200 dilution times of MGW is better than 100 times and some treatments had no significant effects.
