The influence of bromoxynil, N fertilization levels and method of sowing on weed control and yield of wheat
|

Abstract: Field experiments were carried out for two successive seasons to investigate the effect of the interaction between methods of sowing ( drilling and broadcasting) and rates of bromxynil under different nitrogen fertilizer levels on weed control and yield of Wheat ( grain and straw).
The results showed that the higher rates of bromoxynil ( 1.0 and 1.5 L / fed. ) were significantly more effective in controlling broadleaved weeds in both seasons compared to the lower rate ( i.e.0.5 L. / fed.). The interaction between bromoxynil at 1.5L./fed. and the drilling method gave the best control of weeds compared to the broadcasting method; while the two methods of sowing gave similar results when bromoxynil at 1.0 L./ fed. was applied. The results obtained for the grain yield, however, showed that the interaction between 1.0L./Fed. of bromoxynil in the drilling method gave a significantly higher grain yield compared to any other treatment in both seasons. This was also clear in results obtained for the interaction between the three factors under investigation. Thus, the highest significant yield of grain was obtained by bromoxynil at 1.0 L/fed. in the drilling method under 90 kg nitrogen in both seasons. Straw yield was significantly increased by the higher rates of bromoxynil increased by the higher rates of bromoxynil (1.0 and 1.5 L./fed.) and harvest index was significantly improved using the drilling method but in one season only.
