New approaches in plant
production gain importance due to the accumulation of organic residues and the
problems caused by agricultural inputs that are used extensively in traditional
methods. For this purpose, materials such as plant and animal wastes and compost
are widely used. In this study, the effects organic and chemical fertilizer
source on the essential nutrient content, nitrate accumulation and the growth
of lettuce plant (Lactuca sativa L.) were investigated. The experiment was
carried out according to the randomized plots experimental design under
greenhouse conditions, with 2 chemical fertilizer applications (with or without
chemical fertilizer), 1 compost material (kitchen waste compost), four
different doses (0, 8, 16, 24, 32 g kg-1) and 3 replications.
For
15
kg pure N da-1 as chemical fertilizer, 15-15-15 (N:P2O5:K2O)
fertilizer was used. Overall, kitchen waste compost (KWC) applications
increased plant growth and nutrient content. However, the most significant
increases occurred in the trial subjects where chemical fertilizer and KWC were
applied together. The use of KWC together with chemical fertilization increased
the plant height, wet weight and dry weight, as well as nitrate (NO3)
accumulation, nitrogen (N), calcium (Ca) and magnesium (Mg) content in the
plant more than KWC. While the highest plant height values were
found in 32 g kg-1, 24 g kg-1 of chemical fertilizer and
KWC medium in wet and dry weight, the highest N content and nitrate (NO3)
accumulation were obtained at 16 g kg-1 dose. As
a result, compost applications were effective in nutrient concentrations when
used with chemical fertilizers and nitrate accumulation remained at acceptable
values.
