Description
  • The work brings the results of the formation of yield elements in winter wheat {Triticum aestivum L.) grown in ecological agriculture. Two cultivars of winter wheat, EBI and ESTICA, were grown in stands of different densities (with 250 and 500 seeds sown per 1 m2 respectively) and in two periods of sowing (September and October). In the vegetative period there was a loss of plants during the period of sowing and germination of about 20% and with the higher sowing rates of up to 30%. With late sowing, 45 to 55% plants were lost during germination. The yields were higher with early sowing in the second half of September. The sowing rate of 250 seeds per 1 m2 was insufficient, the optimum rate would have been 400 seeds. In each ear up to 35 caryopsis with a mass of 1.65 g can be formed and the mass of 1000 grains should be high, in our experiment it was 47.2 g. This structure of the yields components brought an average yield 6.56 tonnes per

  • Práce přináší výsledky sledování výnosových prvků u ozimé pšenice (Triticum aestivum L.) pěstované v ekologickém zemědělství. Dvě odrůdy pšenice ozimé, EBI a ESTICA byly pěstovány při různé hustotě porostu(250 a 500 semen setých na 1 m2) a ve dvou dobách setí (v září a v říjnu). Ve vegetativním období došlo k úbytku rostlin v období setí-vzcházení okolo 20% a u vyšších výsevků až o 30%. S pozdním výsevem ubylo 45 - 55% rostlin během vzcházení. Výnosy byly vyšší při časném setí v druhé polovině září. Množství výsevu by mělo být vyšší než 250 obilek na 1 m2, optimální by bylo 400 obilek na 1 m2. V každém klasu by mělo být 35 obilek s hmotností 1,65 g a hmotnost 1000 obilek by měla být vysoká - v našem pokusu to bylo 47,2 g. Tato struktura přinesla v průměru uvedeného pokusu výnos 6,56 tuny na hektar. (cs)
