<p><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;">This study was conducted in order to determine the effects of beneficial microorganisms on two lettuce cultivars ('Maritima' and 'Patagonia') in organic production. Two beneficial microorganisms, namely mycorrhiza (</span><i style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">Glomus</i><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;"> spp.) and </span><i style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">Trichoderma harzianum</i><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;"> stain KRL-AG2 and their combination (mycorrhiza + </span><i style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">T. harzianum</i><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;">) were tested comparing with the control (no treatment). Lettuce (</span><i style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">Lactuca sativa</i><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;"> L.) plants were grown between 14.11.2016 and 02.03.2017 in an unheated greenhouse with a plant density of 5.7 plant m</span><span style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">-2</span><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;">. At the end of the growing period, yield and head quality parameters such lettuce size, color, vitamin C and nitrate contents were determined. The results showed that cultivar 'Patagonia' gave the highest yield (2.18 kg m</span><span style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">-2</span><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;">) and highest head size (366.16 g m</span><span style="margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-stretch: inherit; font-size: inherit; line-height: inherit; font-family: LiberationSansRegular, Arial, sans-serif; color: rgb(51, 49, 45);">-2</span><span style="color: rgb(51, 49, 45); font-family: LiberationSansRegular, Arial, sans-serif;">), however among the tested microorganisms, mycorrhiza had higher performance as beneficial microorganism compared with the other treatments.</span><br></p>
