IMPACT OF SELECTED GROWTH REGULATORS AND EKOLIST ON YELLOW LUPIN SEED YIELD (LUPINUS LUTEUS L.)

Janusz Prusiński, Magdalena Borowska

 

ABSTRACT



A strict, two-factor field experiment in split-block design with the control was carried out at the Mochełek Experiment Station over 1997-1999. Plants of ‘Teo’, traditional yellow lupin cultivar, were treated with varied doses of growth regulators and Ekolist (macro- and micro-nutrient fertiliser) at the beginning of plant flowering. The following growth regulators were applied: auxin – indole-3-butritic acid (A), cytokinin – 6-benzyloaminopurine (C), gibberellin (gibberellic acid) (G), A+C, A+G, A+C+G and Ekolist, all of them applied in three doses: low, medium and high. Over the successive research years the plants were sprayed on June 25, 14 and 14. Over full flowering, 20 control-plot plant flowers on the main stem and branches were counted. Before harvest 20 plants were sampled from each plot to determine the seed yield components. The growth regulators and Ekolist applied limited the unfavourable abscission of generative organs, which resulted in a significantly higher, than the contr

Key words: yellow lupin, growth regulators, Ekolist, seed yield and its components.
