Abstract: 

MOST OF THE WEED SPECIES HAVE AN INHIBITION EFFECT ON CROPS. MOST OF THE WEEDS STUBBLE RETURNE TO THE SOIL AFTER CROP HARVEST AND FROM MORE INTENTION SOIL PHYTOTOXICITY RESOURCE. THE EFFECTS OF SECALE STUBBLES ALLELOPATHY ON THE GERMINATION AND SEEDLING GROWTH OF WHEAT CULTIVARS WAS CARRIED OUT IN THIS RESEARCH. THE TRIAL WAS A FACTORIAL EXPERIMENT BASED ON A RANDOMIZED COMPLETE BLOCK DESIGN WITH 3 REPLICATIONS, CARRIED OUT IN THE GREEN HOUSE OF FACULTY OF AGRICULTURE, BU-ALI SINA UNIVERSITY, IN 2009. EXPERIMENTAL TREATMENTS WERE WINTER WHEAT CULTIVARS (ALVAND, TOUS, SAYSON AND NAVID) AND STUBBLE AMOUNTS OF SECALE BASED ON 0, 20, 40, 60 AND 80 PLANTS M-2 DENSITIES, WHICH ACCORDING TO THE PLANT WEIGHT OF SECALE AT THE HARVEST (15 G PLANT-1) WERE EQUALS TO 0, 7.6, 15.24, 22.86 AND 30.48 GRAM OF STUBBLE PER PLOT. THE RESULTS SHOWED THAT WHEAT CULTIVARS DIDN’T HAVE SIGNIFICANT DIFFERENCE IN LEAF AREA AND LEAF WEIGHT OF PLNT, CHLOROPHYLL INDEX AND TILLER NUMBER PER PLANT. ALL WHEAT CULTIVARS SHOWED A REDUCTION TREND IN ALL CHARACTER, BY INCREASING SEED STUBBLE AMOUNTS. GERMINATION WAS NOT AFFECTED BY CULTIVAR, WHEREAS GERMINATION OF SAYSON AFFECTED BY STUBBLE LESS THAN OTHERS AND HAD THE MOST PLANT DRY WEIGHT AND PLANT TILLERS NUMBER SIGNIFICANTLY. THE LOWEST PLANT LEAF AREA AND CHLOROPHYLL INDEX BELONGED TO NAVID CULTIVAR AT THE ALL STUBBLES TREATMENTS.
