- Abstract
The influence of some plant growth regulators on the nutritive value and energy efficiency of winter pea, variety Mir was investigated. The experiment was conducted in the period 2003-2006 at Trakia University, Stara Zagora, with 3 complex preparations as followed: N-40 (naphthaleneacetic acid - NAA) - 200 and 300 cm3/ha; HP-55 (chlorophenoxyacetic acid) - 100 and 200 cm3/ha and G-31 (chlorophenoxyacetic acid + naphthoxyacetic acid - NOA) - 300 cm3/ha in 300 l/ha solution. The studies demonstrated that the application of growth regulators during the bloom period had no effect on the nutritive value of grain and straw, but had a positive effect on the energy obtained from the biomass of winter pea and the energy efficiency of the production. The highest coefficient of energy efficiency was obtained by treatment with N-40 - 200 cm3/ha - 7.8 for GE; 3.7 for ME and 2.1 for NE, that was by 14.71%, 15.16% and 15.25%, respectively higher compared to untreated control. The combined application of N-40 at a dose 200 cm3/ha with insecticide for control of weevil (Bruchus pisi L.) did not decrease the energy efficiency.
