Integrated control of narrow and broad weeds for corn under Siwa Oases conditions [electronic resource].

Includes references.

Two field experiments were conducted in Tegzerte, Siwa Research Station, Desert Research Center during summer seasonns of 2003 and 2004 to study the influence of combinations of interrow tillage (tilled or none), row width (35 or 70cm.), cover crops (Medicago sativa or Sorghum bic%f) and herbicide (Glyphosate or none) on Zea mays weed control and yield of maize. Post emergence Glyphosate-resistant Zea mays applied at the seven-to eightleaf maize growth stage as a post emergence. The experimental design was a randomized complete block with 20 treatments and three replications. The sequencing process of interrow tillage, narrow rows and Medicago sativa cover crop are the preferable practices that were used in maize early season weed suppression prior to the post-emergence Glyphosate application. In the case of individual factor was the cover crops followed by interrow tillage. The best impact of marital factor i"n this case was the combination between interrow tillage and Med/cago sativa cover crop. Best result, occurred at treatment combinations in the late season weed control was combining between Glyphosate herbicide. narrow rows and interrow tillage. In the case of individual and marital factor were Glyphosate and combination between Glyphosate plus narrow rows are the best, respectively. Interrow tillage, narrow rows, Medicago sativa cover crop and Glyphosate herbicide are important weed management practices that can be integrated into full Z. mays production season.
