Effect of Organic and Chemical Fertilizer Applications on Yield And Chlorophyll Content of Yedikule Lettuce (Lactuva Sativa L.) Plant

This study was conducted in Erciyes University Agricultural Research and Application Land in 2020 to determine the effects of organic and chemical fertilizers applied from the base to the Yedikule lettuce plant on plant yield and plant chlorophyll content. In the study, solid worm manure (100 kg da-1) was preferred as organic fertilizer, while 15 - 15 - 15 compound bottom fertilizer was preferred as chemical fertilizer. Seedlings of lettuce plants were planted with 16 plants in each plot, with a row spacing of 25 cm and a spacing of 50 cm between rows. In the study, the chlorophyll content of plant leaves (SPAD) was examined, as well as the yield parameters of plant height (cm), plant width (cm) and plant fresh weight (g/plant). As a result of the examination, it was determined that chemical fertilizer application had a positive effect on the fresh weight of the plant, and organic fertilizer application had a positive effect on the chlorophyll content
