Effect of soil tillage and weed control on wheat productivity [electronic resource].

Includes reference.

Two field experiments were carried out at EL-Gemmeza Agric. Expt. Sta., ELGharbia Governorate, Middle Delta, dUling 1997/1998 and 19981/1999 seasons to study the effect of some tillage systems including no-till (as a control), Chisel plowing (16-18 cm), moldboard plowing (18-20 cm), subsoiling + chisel plowing and subsoiling + moldboard plowing and weed control treatments (Arelon, Granstar, Grasp and unweeded check) on the growth and yield of wheat and on the spread of weeds in wheat plots. The results of the combined analysis of both seasons could be summarized as follows: Bulk density and salinity of the soil were not significantly affected by tillage treatments in both seasons. Whereas, soil porosity % was affected by tillage treatments in the first season. The highest porosity % was recorded by subsoiling + moldboard plowing. Subsoiling + moldboard plowing significantly surpassed the 4 other systems, and Areton was significantly superior to the other 2 herbicides in depressing weeds at 50, 90 and 120 days from sowing (DFS). The significant interaction indicated superiority of subsoiling + moldboard plowing with Arelon in depressing weed infestation.
