Abstract: 

THE EFFECT OF LIGHT, TEMPERATURE REGIMES(10/20, 25/15, 20/30 (DAY/NIGHT) ) AND DIFFERENT PLANTING DEPTH(ZERO WITH FILTER PAPER, ZERO WITHOUT FILTER PAPER) ,0.5,1,2,3,4 CM ON GERMINATION PERSENTAGE AND SEEDLING EMERGENCE OF REDROOT PIGWEED IN A RANDOMIZED COMPLETE BIOCK DESIGN WITH THREE REPLICATION IN A CONTROLLED ENVIRONMENT WAS EVALUATED.THE RESULTS INDICATED THAT LIGHT DOSENOT HAVE A LOT OF EFFECT ON GERMINATION OF THE SEED, SO THE REDROOT PIGWEED DOSNOT HAVE THE PHOTOBLASTIC PROPERTY.THE FAVORIT TEMPERATURE FOR GERMINATION WAS 25/15 AND THE FAVORITE DEPTH FOR SEEDLING EMERGENCE WAS 2 CM.NO SEEDS GREW AT 3 CM DEPTH AND THE HIGHEST SEEDLING EMERGENCE PERCENTAGE WAS AT THE ZERO DEPTH WITH FILTER PAPER.
