Effect of Some Organic Materials on Yield and Plant Nutrient Content of Curly Leaf Salad (Lactuca Sativa Var. Crispa)

Abstract

Caipira (Lactuca sativa var. Crispa) curly leaf salad varieties used in the study and 3 different organic materials (vermicompost, gidya, leonardit) and their control group using different doses (3%, 6%, 9%) and garden soil (0%) designed as. In this study, it is aimed to determine the effects of vermicompost, gitya and leonardite applications on plant nutrient content in different doses as organic material in salads that have an important place in human nutrition and when chemical nitrogen fertilizers are applied. According to the research findings, the effects of organic substances applied on the yield components examined were found to be significant. Although vermicompost application increased the yield approximately 2 times, no statistical difference was found between the doses. It was also determined that the effect of vermicompost on early growth in curly leaf salad was statistically significant and vermicompost gave good results especially to the intake of K+, Zn+ and Cu+ elements into the plant. In general, it has been determined that applications of gidya in terms of plant nutrient content do not give positive results.
