Forage yield and nutritive value of Tanzania grass under nitrogen supplies and plant densities R. Bras. Zootec.
Freitas,Fabrício Paiva de; Fonseca,Dilermando Miranda da; Braz,Thiago Gomes dos Santos; Martuscello,Janaina Azevedo; Santos,Manoel Eduardo Rozalino.
The objective of this experiment was to evaluate the nitrogen and plant density influence on the yield, forage dissection and nutritive value of Tanzania grass (Panicum maximum Jacq.). The design was of completely randomized blocks with three replications in a factorial arrangement with four nitrogen levels (0, 80, 160 or 320 kg/ha N) and three plant densities (9, 25 or 49 plants/m²). The plots were cut at 25 cm from soil level when the canopy reached 95% of light interception. The total dry matter forage yield and dry matter forage yield per harvest increased linearly with the nitrogen fertilization. The leaf and stem yield had the same response. The senesced forage yield was quadratically influenced by the nitrogen. The stems ratio in the morphologic...
