Abstract
Two field experiments were conducted at experimental Farm of National Research Centre at Nobarya during 1998 and 1999 seasons to study the effect of some weed control treatments [unweeded - Hand hoeing - Fluroxypyr herbicide] and foliar micro elements fertilization (Greensit and Stemifule) on growth, yield and its components, chemical composition and associated weeds of maize plants.
The main results could be summarized as follows:
All weed control treatments alone or in combination with foliar fertilization had significant effect on fresh and dry weight of maize weeds after 45 and 75 days from sowing. The highest efficiency in decreasing fresh and dry weight of total weeds was obtained by hand hoeing with Greensit or with Stemifule followed by Fluroxypyr with Greensit or with Stemifule.
. All weed control treatments as well as both microelements fertilizer treatments markedly increased growth characters of maize [plant height, No. of leaves per plant, Fresh weight of plant and leaf area] yield and its components [number of ears, ear length and diameter, No. of grains/row, weight of ear grains per plant, weight of 100 grains and grains yield/fed. as well as chemical composition [oil %, protein % and total carbohydrates %], Maximum values were obtained by hand hoeing with Greensit or with Stemifule followed by Fluroxypyr with Greensit or with Stemifule. On other hand, the lowest values were obtained by unweeded plants.
