The fruit and leaves of bitter melon, a medicinal plant which is particularly used for digestive system

diseases and wound treatments, are substantially rich in minerals and vitamins, especially Fe, Ca, P and vitamin

B. There are a limited number of studies conducted on the nutrient needs of this plant, which is cultivated in the

Aegean and Mediterranean Regions of our country. It is known that mycorrhizae, which display a type of symbiosis

based on the mutual benefit between fungi that produce hyphae and plant roots in the soil, increase the uptake of

especially phosphorus and certain other elements by plants under controlled field conditions. In the present study,

G. mosseae type mycorrhiza was inoculated (500 spore pot-1) during sowing under greenhouse conditions in order

to observe the effectiveness of mycorrhiza application. In the study, which was also conducted as a pot experiment

in order to determine the appropriate amount of phosphorus and iron fertilizer for the plant, fertilizer applications

were made at doses of 0-5-10-15 kg P2O5 da-1 and 0-5 mg Fe kg-1. In the study, it was aimed to observe the effect

of mycorrhizal inoculation on the plant P and Fe uptake in bitter melon. After sowing, the germination and growth

conditions of the plants were observed and the leaf chlorophyll values of the plants were measured until the time

of flowering. According to the variance analyses conducted on the chlorophyll measurements of the plants, it was

determined that mycorrhizal inoculation P<0.05, phosphorus fertilizer application P<0.01 and iron fertilizer application

P<0.05 had an effect on chlorophyll content, moreover, there was an interaction between mycorrhizal

inoculation and P application.
