Abstract

The influence of calcium levels on the growth of Stylosanthes guyanensis (Aubl.) SW. c v "Cook" plants was studied under the following treatments: T1 (200 mg of calcium/litre); T2 (133.33 mg of calcium/litre); T3 (66.66 mg of calcium/litre) and T4 (without calcium). The study was carried out in a hydroponic media with Hoagland & Arnon's number one nutrient solution. The experiment was designed as a completely randomized split-plot design, considering the five samplings performed in 14 day intervals as main plots. The influence of different treatments was evaluated through leaf area (LA), specific leaf area (SLA), leaf weight ratio (LWR), and leaf area ratio (LAR). The results obtained indicated that stylo plants had a better development in the 200 mg of calcium/litre level in nutrient solution.
