Effect of autumn nitrogen fertilization on winter oilseed rape growth and yield parameters

Popis výsledku v původním jazyce

Autumn fertilization of winter oilseed rape with nitrogen was monitored in exactly delimited small field experiment in the period of 2013/14-2015/16. The cultivar used was DK Exstorm, sowing amount: 50 seeds/m(2) and fertilizer applied in autumn was Ureastabil - granulated urea with urease inhibitor (NBPT). The application period was at the end of October, doses 40 and 80 kg N/ha. Research results confirmed a statistically important effect of autumn fertilization on growth of the above-ground biomass and roots. Statistically important effect on seed yield was confirmed, too. The dose of 40 kg N/ha resulted in the highest seed yield, on average by 10,6 % higher than reference (5,7-6,5 t/ha). On the other hand, the dose of 80 kg N/ha increased the seed yield only by 7,4 % on average (5,4-6,3 t/ha). Fertilization effects on the oil content and one thousand seeds weight were statistically insignificant. The results show that considering the given local and weather conditions and low mineral nitrogen cont
