Description
Seven phosphorus rates in the nutrient solution were studied in a greenhouse experiment for Brachiaria brizantha (Hochst) Stapf. Plants had 54 days of growth and 49 days of regrowth. Significant responses in forage yield, tiller number and root dry weight were found. Plant tops were divided into four parts and phosphorus concentration in each one significantly changed with phosphorus rates. Sampling of the young leaf blades and analyzing for phosphorus is proposed for diagnostic purposes. A critical phosphorus concentration of 1.2 g kg-1 is suggested as the critical level in the young leaf blades.
