| dc.description.abstract | Abstract :
A field experiment was conducted at the Bangabandhu Sheikh MujiburRahman Agricultural University, Gazipur, Bangladesh during winter season of 2006-2007 to determine the effect of plant growth regulators on seed yield of carrot. Three plant growth regulators viz. NAA 100 ppm, Ethrel 100 ppm, GA3 50 ppm, GA3 100 ppm, GA3 150 ppm, GA^ 200 ppm and untreated control were included in this study. The application of different plant growth regulators in different concentrations had significant impact on the seed yield of carrot. The highest seed yield (256.90 kg ha1) of carrot was found by GA^ 200 ppm treatment. The highest seed germination percentage (93.33) and seed vigor index (3.16) were also recorded ffomGA3 200 ppm treatment.This treatment therefore may be recommended for seed production of carrot in ShallowRedBrownTerrace soil of Madhupur tract. | en_US |
