Influence of some growth regulators on productivity, chemical composition and nutritive value of spring vetch was investigated in Trakia University, Stara Zagora, during the period of 20022003. Three complex substances N-40 (naphthaleneacetic acid NAA) 20 and 30 cmз/da, HP-55 (chlorophenoxyacetic acid) 10 and 20 cm3/da and F-31 (chlorophenoxyacetic acid + naphthoxyacetic acid NOA) 30 cmз/da were evaluated. Treatment of spring vetch, variety 666 in full bloom stage with above mentioned growth regulators had positive effect. The highest effect was obtained after treatment with HP55, 10 сmз/da. The yield of grain and straw was increased 14.915.6% and yield of crude protein 14.319.3% and feed units 14,116.3%. Growth regulators had no substantial effect on the chemical composition and nutritive value of grain and straw.
