Investigation on effects on efficiency and some quality criteria of (Lactuca sativa var. crispa) whit different nutritional recipients in I culture

This study was carried out in the Physiology laboratory of Van Yuzuncu Yil University Faculty of Agriculture, Department of Horticulture, in the climate and in the aquaculture. This thesis study was carried out in order to determine the yield and quality differences which will be produced as a result of applications of different nutrient solutions applied to Caipira variety curly leaf lettuce prepared in a still water culture. Seven different applications were made in the study. Control group 1 used standard hoagland solution. By modifying the standard Hoagland nutrient solution, in 2nd application, Magnesium (Mg) and Phosphorus (P) were increased by 10 %. In the 3rd application, Mg and Potassium (K) were increased by 10 %. In the 4th application only Nitrogen (N) was increased by 10 %. In 5th application, micro elements and N are increased by 10 %. On the 6th application, micro elements and K are increased by 10 %. In the seventh application, Mg and N contents are increased by 10 %. At the end of the study, the weight of chronos, root weight, root weight, number of marketable leaves, number of leaves taken, amount of dry matter dissolved in water, amount of chlorophyll and color were analyzed. As a result of the analyzes made, the difference between the plant growths in terms of crown weight and crown height was found to be statistically significant (p˂0.05). The fourth application has been the best development in terms of both crown weight and crown height and hence yield.
