|Title:||Action Of Potentials Of Hydrogen On Growth And Productivity Of Sage (salvia Officinalis L.) [ação De Potenciais Hidrogeniônicos No Crescimento E Produtividade De Sálvia (salvia Officinalis L.)]|
|Abstract:||The soil potential of hydrogen (pH) is a parameter that indicates the acidity or alkalinity level. Plants are known to react differently to changes in the soil pH. Few studies have related growth and productivity of medicinal plants to the soil pH variation. The aim of this experiment was to evaluate the effect of different potentials of hydrogen in Oxisol on sage growth and productivity. With the aid of a soil acidity neutralization curve, different CaCO3 levels were applied to reach pH values of 4.5, 5.0, 5.5, 6.0 and 6.5. The experiment was carried out in a greenhouse during 18 months, covering sowing, transplanting and three-pruning phases. Plant height, leaf, root and shoot dry matter (sum of leaf, branch and stem dry matter), leaf area and root volume were evaluated. Sage growth and productivity were directly affected by the soil pH variation. The maintenance of pH > 5.0 was enough to significantly increase leaf area, and leaf and shoot dry matter of sage plants at 52.2%, 60.5% and 42.4%, respectively, and did not affect root development of sage plants grown in soils presenting different pH levels.|
