Abstract
The present study aims to contribute further to identify the behaviors Menofia grass fields in order to facilitate resistance.
Amount of rain does not meet the needs of the farming where the average annual rainfall 38 mm, so agriculture is dependent on irrigation from the Nile and the sub-Menoufi wind and follow the system of permanent irrigation, and drainage are covered by banks and the public.
The agricultural cycle is the tripartite system of cotton is used for the session to maintain.
The study on the division of field grass crops associated with the study:
* Weeds associated with crop completely (starting from cultivation until harvest) and the weeds associated with crop part (the period in his life) and the latter can be either early or late appearing to emerge.
It turns out that the greater the crop growth period (winter or summer) is less than the proportion of weeds associated with its wholly and partially associated with increased grass and vice versa.
