Determination of the Effects of Different Nitrogen and Phosphorus Applications On Leaf Area of Echinacea (Echinacea purpurea L.)
Journal Title: ISPEC Journal of Agricultural Sciences - Year 2023, Vol 7, Issue 1
Abstract
This study was conducted to determine the changes in the leaf area, particularly in the drug part used for medical purposes, of Echinacea purpurea plant caused by different nitrogen (0, 10, 20, and 30 kg/da) and phosphorus (0, 5, 10, and 15 kg/da) applications. The change in leaf area was determined to be between 23.01-62.95 cm2. Based on the measurements obtained from the leaves in the study, a simple and highly accurate model was developed by measuring the length and width of the leaf on the plant without the need for expensive equipment, without damaging the leaves, or harvesting them for future Echinacea studies. The developed model was modeled as Leaf area = (-0.06367) + (0.007245 x L) + (0.02498 x AVW) - (5.913e-05 x L²) + [0.9975 x (L x AVW)] (L: length and AVW: average width). The model was found to have a high R-squared value (R² = 0.9993).
