Evaluation of seed yield and yield components in selected soya (\kur{Glycine max} (L.) Merrill.) cultivars in region with less favourable conditions
VŠETEČKA, Petr
The aim of this master thesis was the finding out of potential of growing the soybeans in the area with not so suitable growing conditions. The next aim was to perform the experiment with application of leaf fertilizer EGT Fulhum which increases root system volume. In the years 2016 and 2017 was in the altitude 395 m established the field experiment with the variety Amandine and since the year 2017 was also joint the experiment with the very early variety Abeline. Within these cultivars of soybean were evaluated these parameters: Seed yield, the 1000 seed weight, seed oiliness, plant height, number of pods on one plant, number of the early branches and weight of roots. The seed yield was very variable from the point of view of the year. The yield in the year 2016 was above-average, the control variant reached the yield 2,93 tons per hectare and variant treated by Fulhum 2, 78 tons per hectare. One of the studied parameter was the nitrogen content and based on the results of this parameter was noticeable reduction of nitrogen content of the treated variant in the comparison with control variant. In the further year were two compared two varieties - Amandine and Abeline. Within the both varieties were involved to the experiment the control variant and the variant treated by plant auxiliary substance. In the year 2017 was confirmed the influence of the crop area establishment on the yield quality parameters. The progress of weather confirmed the high requirements of soybean on the good rainfall conditions. Seed yield of the variety Amandine was 1,07 tons per hectare in the case of the treated variant, by control variant it was 0,88 tons per hectare. The difference of the seed yield between both variants of the variety Abeline was very little, it was 0,90 tons per hectare by the treated variant and 0,93 tons per hectare by the control variant. The application of the plant auxiliary substance didn't cause, on average, the improvement of the studied parameters so the using of this substance, for the improvement of these parameters almost doesn't make any sense.
