EFFECT OF FLURPRIMIDOL ON NARROW- LEAF (LUPINUS ANGUSTIFOLIUS L.) AND WHITE (LUPINUS ALBUS L.) LUPINS SEED YIELDING
Two strict field two-factor experiments were carried out at the Mochełek Experiment Station of the Bydgoszcz University of Technology and Agriculture over 1999-2001 and included traditional narrow-leaf lupin ‘Troll’ and white lupin ‘Bardo’ cultivars. At the beginning of budding (once) and flowering (once) and twice on those stages the plants were sprayed with Topflor 015SL containing 15% of flurprimidol at the doses of 0.15, 0.30 and 0.45 dm·ha-1 in 300 l of water per ha. The reaction of the lupin species researched to flurprimidol varied. Significantly highest narrow-leaf lupin seed yields were obtained when Topflor was applied at the dose of 0.30 dm·ha-1 at the beginning of flowering, and white lupin after the applying that dose twice, at the beginning of budding and at the flowering of the main stem. Flurprimidol enhanced the number of pods on lateral shoots and the number of pods per plant in white lupin; in narrow-leaf lupin there was observed its unfavourable (insigni
