ABSTRACT: In field experiment carried out in years 2003-2007 at the Research Station at Mochełek (53o13’ N; 17o51’ E) near Bydgoszcz on good rye complex soil, the effect of fertilisation (147 and 221 kg NPK•ha-1), plant protection (control – no plant protection, herbicide, herbicide + fungicide), and seeding density (400 and 600 grains•m-2) on the yield and grain technological quality of winter wheat cultivar Tonacja grown in short-time monoculture was estimated. Research showed that winter wheat cultivation in 3-year monoculture on light soil caused a significant decrease in its yield from 5.70 t•ha-1 in the first year of monoculture to 2.92 t•ha-1 and 1.73 t•ha-1, respectively, in the second and third year of continuous cultivation. Advantageous effect on the size and quality of the grain yield of winter wheat grown in monoculture was given by the application of herbicide Huzar 05 WG and an increase in the fertilisation dose of NPK. Single application of fungicide Alert 375 SC during vegetative growth and an increase in seeding density did not create such an effect.

ABSTRACT: In a field experiment in years 2007-2009 at Mochełek (53o13’ N; 17o51’ E) near Bydgoszcz on good rye complex soil, the effect of forecrop (spring barley, blue lupine, blue lupine + spring triticale, spring rape) and nitrogen fertilisation (40, 80, 120, and 160 kg N•ha-1) on the yield and grain technological quality of winter wheat cultivar Tonacja was estimated. It was stated in the research that significant elements in the agronomical practices of winter wheat grown on light soil, although affecting independently, are forecrop and nitrogen fertilisation. Grain yield and its quality on a worse stand cannot be improved by increased fertilisation. The most favourable standfor winter wield yield was blue lupine in pure sowing. Spring rape, and also a mixture of lupine with spring triticale and spring barley were worse forecrops than blue lupine. On light soil in region and years with relatively low precipitation sums during the growth period, independently of forecrop, nitrogen fertilisation above 80 kg N•ha-1 did not increase significantly grain yield but affected positively its technological quality.

ABSTRACT: In a three-year field experiment carried out at Mochełek in the vicinity of Bydgoszcz on good rye complex soil over 2003-2005 there were evaluated an effect of the forecrop, a varied soil tillage under the forecrop and the herbicide dose Huzar 05 WG on weed infestation and yield of Kris winter wheat. The experiment demonstrated that winter wheat grain in the stand after narrow-leaf lupin was more plump and the yields were higher than after spring barley as well as that the kind of the forecrop did not have a considerable effect on the characters of technological quality of bread-baking grain. The tillage method for winter wheat forecrops did not affect weed infestation and yield. Decreasing the dose of Huzar 05 WG herbicide by 1/3, as compared to the dose recommended by the manufacturer, is possible when growing winter wheat as it does notlead to a decrease in the grain yield, despite a slight increase in weed infestation.

ABSTRACT: 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.
