EFFECT OF PRECEDING CROPS, TILLAGE AND WEED CONTROL TREATMENTS ON GROWTH AND ASSOCIATED WEED CHARACTERS OF CORN
Agronomy Department, Faculty of Agriculture, Mansoura University, Egypt.
Abstract
The field experiment was carried out at the Experimental Station Farm in Agronomy Department, Faculty of Agriculture, MansouraUniversity, during 2014 and 2015 seasons to determine the effect of preceding crops, tillage and weed control treatments as well as their interactions on growth and associated weed characters of corn (Zea mays L.) Single Cross Giza 168 yellow (S.C. 168). Each preceding winter crop (wheat, Egyptian clover and filed bean) treatment was carried out in separate experiment. Every experiment of preceding crop was conducted in strip-plot design with three replications. The obvious results of this investigation can be summarized as follows:
Sowing field bean as a preceding crop of corn exceeded other preceding crops and produced the highest values of all studied characters over both seasons.
The highest values of corn growth characteristics and the minimum values of fresh and dry weights of total weeds/m2 were achieved by using chisel plow twice.
The maximum averages of growth characteristics were achieved as a result of controlling the growing weeds in corn field by hoeing two times before the first and second irrigations (after 21 and 35 days from sowing). Two hoeings treatment more effective than other studied weed control treatments in striving weeds, subsequently significantly decreased fresh and dry weights of total weeds/m2 and produced the lowest values.
Finally, it can be concluded that sowing field bean or Egyptian clover as preceding crops before corn and tillage field by using the chisel plow twice besides controlling weeds growing in field by hoeing twice in order to maximize growth at the same time reduce weeds competition under the environmental conditions of Dakahlia Governorate, Egypt.
