Research on agriculture and the environment described by scientists at Suleyman Demirel University
2009 DEC 24 - (VerticalNews.com) -- "This research was conducted to determine the effects five different nitrogen doses (N 0, 50, 100, 150 and 200 kg ha(-1)) and four phosphorus doses (P2O5 0, 40, 80 and 120 kg ha(-1)) on root and leaf yields and yield components of forage turnip (Brassica rapa L.) under Mediterranean region of Turkey in the 2006 and 2007 growing seasons," investigators in Isparta, Turkey report.
"According to averages of two years, the effect of N doses was significant at all components and P doses were significant at leaf yield, leaf DM yield, root and leaf CP contents, leaf CP yields, ADF and NDF contents in root and leaf. N doses increased root length, root diameter, root yield and DM yield, leaf yield and DM yield, root CP content and yield, leaf CP content and yield, P treatments increased leaf yield, leaf DM yield, root CP content, leaf CP yields," wrote M. Turk and colleagues, Suleyman Demirel University.
The researchers concluded: "Nitrogen and phosphorus doses decreased ADF and NDF contents of root and leaf of forage turnip."
Turk and colleagues published their study in the Journal of Food Agriculture & Environment (Effects of fertilization on root and leaf yields and quality of forage turnip (Brassica rapa L.). Journal of Food Agriculture & Environment, 2009;7(3-4 Part 1):339-342).
