To determine the effect of N fertilizer placement, N fertiliser rate and N application timing on the competitive ability of wheat (Triticum aestivum L.) in reducing the growth and seed production of wild radish (Raphanus raphanistrum) in dryland no-tillage cropping system in the Western Australian grainbelt.
Nitrogen fertilizer timing (early or late) and placement (banded or broadcast) did not have any significant effect in reducing the growth and seed production of wild radish.
