Abstract

The objective was to obtain information for Panicum maximum v. Tanzânia related to the combined supply of potassium and magnesium, through the evaluation of the number of tillers and leaves, leaf area, leaf chlorophyll concentration, and shoots dry matter yield. An experiment was carried out in a greenhouse by using nutrient solution during the Spring season in Piracicaba, state of São Paulo. An incomplete 52 factorial was used, with potassium and magnesium rates, in a randomized block design, with four replications. Plants were harvested twice. Potassium and magnesium rate combinations highly influenced shoots yield in the second harvest. Potassium rates significantly changed the number of tillers and leaves, and leaf area at both growth periods, whereas forage yield was influenced only in the first growth. Magnesium rates resulted in changes in chlorophyll concentration in the two growths, but promoted changes in leaf area in the second growth.
