AFALON 50 WP HERBICIDE DOSE REDUCTION POTENTIAL WITH A DIFFERENT POST-HARVEST TILLAGE IN BLUE LUPIN
Field experiments were carried out over 2002-2004 at the Mochełek Experiment Station, of the University of Technology and Agriculture in Bydgoszcz, on light good-rye-complex soil. Blue lupin was grown after winter wheat. Two factors wereexamined: post-harvest tillage: A – skimming + harrowing, B – skimming + harrowing + white mustard intercrop, C – without post-harvest tillage; dose of herbicide: a – Afalon 50 WP – 1.25 kg•ha-1, b – Afalon 50 WP – 0.83 kg•ha-1. It was demonstrated that eliminating post-harvest tillage led to a decrease in the blue lupin seed yield. However the favourable effect of the white mustard stubble intercrop ploughing-in on blue lupin yielding was not significant. The increase in weed infestation as a result of the Afalon 50 WP herbicide dose reduction from 1.25 to 0.83 kg•ha-1 did not affect blue lupin yield.
