| Title : | INFLUENCE OF MINERAL FERTILIZERS AND PLANTING DENSITY ON THE GROWTH, DEVELOPMENT AND YIELD OF NARROW-LEAVED LAVENDER (Lavandula angustifolia Mill |
| Abstract : | The purpose of the research was to establish the influence of cultivation technologies on the productivity of narrow-leaved lavender. In a two-factor field experiment, the effects of three options for planting density (14.9 thousand plants/ha, 20.0 thousand plants/ha, 28.6 thousand plants/ha) and five options for the main application of mineral fertilizers (N90P90K90, N120P120K120, N180P180K180 and N240P240K240) on biometric dimensions, inflorescence yield, essential oil yield were studied. In a one-factor experiment, the influence of the foliar application of mineral fertilizers (N, P, K separately and NPK together) on the productivity of inflorescences and the content of essential oil was studied. It was established that increasing the density of planting plants increased the productivity of narrow-leaved lavender. In the variants with the highest planting density - 28.6 thousand plants/ha, the yield of freshly picked inflorescences was from 5.51 to 9.48 t/ha, and the yield of essential oil was from 61 to 107 l/ha, depending on the dose of fertilizer application. A positive effect of the application of mineral fertilizers on lavender yield and essential oil yield was revealed. The highest yield of freshly picked inflorescences of 5.49-9.79 t/ha and the yield of essential oil 60-107 l/ha, depending on the density of planting, was obtained with the main application of mineral fertilizers in the dose of N180P180K180. Foliar application of mineral fertilizers increased the productivity of lavender's inflorescences (N-by 8.1%, P-by 4.4%, K-by 7.4% compared to the control - without foliar treatments), but reduced the content of essential oil (N-by 4.6 ml/kg, P-by 4.5 ml/kg, K-by 2.9 ml/kg). Foliar application of complex fertilizer (NPK) increased the yield of lavender by 9.6%, reducing essential oil content by 2.7 ml/kg. The content of essential oil in dry inflorescences of narrow -leaved lavender among the investigated variants varied from 35.3 to 39.9 ml/kg. |
