Effect of different rates of Pielik and Chwastox on yield and content of protein and nitrate in perennial ryegrass varieties



Effect of different rates of Pielik and Chwastox on yield and content of protein and nitrate in perennial ryegrass varieties



Zeszyty Problemowe Postepow Nauk Rolniczych (282): 249-259



In field trials at Lipki in 1973-5, perennial ryegrass Mako, Gazon and Nadmorska were treated with 1.5, 3 or 5 l Pielik (2,4-D) or 2, 4 or 6 l Chwastox (MCPA)/ha. Herbicide treatments increased DM yields at the 1st cut by 4.8-14%. Pielik decreased yields at the 2nd cut by 12-23%. The highest rates of both herbicides decreased yield at the 3rd cut by 5-6% compared with untreated controls, reduced total and digestible protein contents and increased nitrate content.
