Abstract
Description
In the years of 2013–2014, pot experiments were
conducted to determine the influence of sowing depth and seed
size on the dynamics of spring wheat emergence and yields. The
study was carried out in Mitscherlich pots using the random block
method, in four replications. The experiment included spring
wheat cultivar Tybalt. The first factor of the experiment was the
sowing depth of seeds (1, 3, 5, 7 cm), while the second factor
was the seed size. Four levels of the second factor were taken
into account: a1 – certified material (purchased), a2 – small-sized
seeds (1.8 – 2.2 mm), a3 – medium seeds (2.2 – 2.5 mm), a4 –
large seeds (> 2.5 mm). Adequate size of seeds for the study was
ensured by sorting out of the certified material on Vogel screens.
The research showed the joint impact of seed size and sowing
depth on grain yield formation, number of plants and ears per
pot and production tillering. The application of the sowing depth
of 7 cm resulted in a significant decrease in grain yield from the
pot of all seed fractions, especially the smallest fraction of seeds
(1.8 – 2.2 mm). The variant of sowing large seeds (> 2.5 mm) at
the depth of 3 cm turned out to be the most beneficial for grain
yield.
