The development of root system of forage grasses is influenced by the supply of mineral nutrients. The experiment was carried out in a greenhouse in Piracicaba, São Paulo State, with the objective of evaluating the effect of nitrogen and magnesium rates on dry mass yield, total length and surface, specific length and surface, and concentrations of nitrogen, magnesium, calcium and potassium in the root system of Brachiaria brizantha Stapf. cv. Marandu. It was studied five rates of nitrogen (2, 9, […]

A greenhouse experiment was carried out during the Spring 2004 aiming to evaluate Panicum maximum cv. Tanzania root system as related to the combined supply of K and Mg in nutrient solutions. A randomized block design was used, with four replications, in an incomplete 52 factorial experiment with 13 combinations between K and Mg fertilization rates, in mmol/L: 0.4K/0.05Mg; 0.4K/1.35Mg; 0.4K/2.65Mg; 3.2K/0.70Mg; 3.2K/2.00Mg; 6.0K/0.05Mg; 6.0K/1.35Mg; 6.0K/2.65Mg; 8.8K/0.70Mg; 8.8K/2.00Mg; 11.6K/0.05Mg; 11.6K/1.35Mg, and 11.6K/2.65Mg. Roots were collected after the second harvest of […]
