THE STUDY OF THE IMPACT OF SOIL LIMING ON THE MORPHOLOGICAL AND PRODUCTIVE INDICATORS OF SAGE (SALVIA OFFICINALIS L) IN THE SECOND YEAR OF THE EXPERIMENT AND THE CORRELATIONS BETWEEN THEM

Sage (Salvia officinalis L) is the most widespread medicinal plant in Albania and which ranks first for export among aromatic and medicinal plants. It extends almost across the entire Albanian territory, being represented by morpho-biological and chemical variations depending on the soil and the areas of extension. For the economic interest it has had and continues to have, it is cultivated in some areas of Albania and mainly in the stony soils of Koplik. The chemical composition of the herb depends greatly on the chemical composition of the soil and the climatic and soil conditions. The essence content varies depending on the climatic and soil conditions and ranges from 2.6% contained in the sages of the southern part of Albania to 3.8% and rarely 4.1% of the sages in the northern part of Albania. The content of calcium carbonate (CaCO3) affects the morphological indicators, production, and chemical composition of sage herb. Precisely, to determine this influence, a field study was undertaken on sage development rate and essence content. The experiment was set up with four variants and four repetitions. The variants are: V1= no liming, V2= 40 kv/ha lime, V3= 80 kv/ha lime and V4 = 120 kv/ha lime.
