The response of wild oats (Avena fatua L.) to sowing rate and herbicide application
No full textA
2-year field study was conducted during the rainy seasons of
1999 and 2000 at Houfa in northern Jordan, to study the influence
of various sowing rates (20kg ha–1, 40kg ha–1
and 60kg ha–1) and 2,4-D application at two growth
stages (stage 13 (3-leaf) and stage 44 (Mid boot)) on yield
components and productivity of wild oats. The highest biomass
and grain yields were produced at 60kg ha–1 and the
lowest at 20kg ha–1 in both seasons. On the other
hand, the highest number of tillers per plant was produced at
20kg ha–1 and the lowest at 60kg ha–1
in both seasons. Differences in weed number and fresh weight
were significant among various weed control treatments in both
seasons. Hand-weeding proved to be the best weed control method.
In both growing seasons, yield reductions occurred when 2,4-D
esters were applied to oats at stage 13 (3-leaf). Hand-weeding
was more effective than 2,4-D applications in suppressing weed
growth.African Journal of Range & Forage Science 2003, 20(3): 239–24
