During the period of 2003 2005 in Trakia University Stara Zagora influence of some plant growth regulators on chemical composition of winter pea variety Mir was investigated. Experiment was conducted with 3 complex preparations as follows: N-40 (naphthaleneacetic acid NAA) 20 and 30 cm3/da; HP-55 (chlorophenoxyacetic acid) 10 and 20 cm3/da and G-31 (chlorophenoxyacetic acid + naphthoxyacetic acid NOA) 30 cm3/da in 30 l/da solution. Treatment of winter pea, variety 'Mir'in full bloom stage with above mentioned growth regulators had no substantial effect on the chemical composition of grain and straw. Positive tendency for increasing amount of crude protein and decreasing amount of crude fiber into the grain was observed after application with growth regulator HP-55 10 cm3/da.
