EFFECT OF VERMICOMPOST (COW MANURE) AND MYCORRHIZAL ON SOME PHYSIOLOGICAL CHARACTERISTICS OF TURNIP (BRASSICA RAPA L.) IN HYDROPONIC CULTURE

Excessive use of fetiilizers to increase the product and distmb the ecological balance and biological environment and also has caused many environmental hazards. The excretion of lru·ge amounts of animal waste as a serious enviromnental problem and it is costly. In a recent research, using earthwonns to conveli organic waste has been considered. Compost derived from the activity of eatihwOims on organic waste, which is called vetmicompost, which ru·e vety valuable and imp01iant nutrients for plants. Using vennicompost reduces the negative effects of cheinical manme and increase soil fetiility. In addition, a myconhizal fungus is stimulating plant growth and affect on some indicators plant growth. In this study, the effect ofvennicompost on three levels (zero, 20% and 50%) and ftmgi at two levels (without fungi and with ftmgi) on tumip plantswas investigated. The results showed that the ftmgal inoculation, getmination, growth pru·ameters (total chlorophyll content, fmit diameter, leaf umber, leaf ru·ea, shoot fresh weight and my weight) was significantly altered, especially in symbiotic fungi with these root of plants in 20% vetmicompost.
