The effects of different application methods and doses of bionur microbial on the yield and quality of curly lettuce

This study was carried out in order to determine the effects of Bionur microbial, contained macro and micro nutrients Thiobacillus spp., different application forms (leaf, soil, both leaf and soil) and doses (leaf: 0, 150, 300, 450 ml / 100 lt, soil; 0, 1.5, 3.0, 4.5 l / da) on yield and quality of curly salad at Tokat Gaziosmanpasa University, Agricultural Research and Application Center in the screenhouse between October 2018 and April 2019. In the experiment, Caipira curly salad was used. Seeds were sown on September 13, 2018 and harvest was done on April 5, 2019. The experiment was carried out in randomized block design with three replications. In this study, yield and quality parameters (total plant weight, marketable plant weight, head length and head diameter) pH, titration acidity, water soluble dry matter of curly salad were investigated. The highest marketable plant yield was obtained at 1.5 lt / da (756.14 g) from soil. The effect of Bionur microbial's application forms and doses on quality parameters was not significantly affected.
