Effect of selected fertilizer a bioactive preparation on winter oilseed rape production
PAUL, Radim
The goal of this thesis was to establish and evaluate a pilot experiment. The effect of 5 variants with the application of biostimulants on yield-producing elements, yield and oiliness of winter rape seeds was evaluated. No biostimulant was applied in the control variant. In variant 1, 0.5 l of ExelGrow was applied in BBCH phase 34. In variant 2, 5 l of Talisman was applied in BBCH phase 39. In variant 3, 2 l and 3 l of Talisman were applied in BBCH stages 39 and 51. In variant 4, 2 l of Talisman was applied in BBCH phase 39, 3 l of Talisman was applied in BBCH phase 51 and 0.5 l of ExelGrow was applied in BBCH phase 51. The experiment was carried out in the 2020/2021 marketing year on a family farm near the village of Dobkov near city of Chotěboř. The content of nutrients in the dry matter of above-ground biomass was only minimally affected by the individual variants. The actual seed yield was positively affected, with variant 4 (4.14 t*ha-1) achieving the highest yield. The oil content of the seeds was not statistically significantly affected by the variants. Variant 2 reached the highest oil content (42.40 %). Of the monitored yield-generating elements, the weight of a thousand seeds was negatively affected by individual variants, the highest was in the control (5 g). On the contrary, the number of pods on the plant was positively affected with a statistically significant difference (150 pcs) in variant 4. The number of seeds in the pod was not affected by the individual variants (18 - 19 pcs).
Winter wheat growing in terms of selected farms
PAUL, Radim
The goal of the bachelor thesis was to establish and evaluate a pilot experiment. The effect of 3 nutritional variants with a graded dosage of nitrogen and the application of a growth regulator with the active substance trinexapac-ethyl on the yield and quality parameters of winter wheat grain was evaluated. There was 145 kg pure nutrient N*ha-1 of growth regulator in scenario 1, 191 kg pure nutrient N*ha-1 in scenario 2 and 191 kg pure nutrient N*ha-1 with applied growth regulator in scenario 3. The experiment was performed on a family farm in the growing season of the year 2018 and 2019 near the village Dobkov by the town Chotěboř. The actual yield was in scenarios 2 and 3 was only slightly increased (in the order of tens of kilograms) in spite of the higher dosage of nitrogen in scenario 2 and the application of a growth regulator in scenario 3. Both the higher dosage of nitrogen and the addition of growth regulator had a positive effect on yield-forming elements, and increased the number of ears per m2, further reducing the average number of grains in a spike in scenarios 2 and 3. The weight of one thousand grains was positively affected by a higher dosage of nitrogen in scenario 2, but negatively affected in scenario 3. All quality parameters (nitrogen content, gluten content, Zeleny test and bulk mass) were positively affected by a higher dosage of nitrogen in scenario 2. The application of the growth regulator in scenario 3 increased the declining trend, the Zeleny test, the gluten content, the nitrogen content and also negatively affected the bulk mass.
Evaluation of yield parameters and first pod height in soya bean (\kur{Glycine max} L.)
This work deals with the influence of the growth regulator on soybean vegetation. The main part of the diploma thesis is the evaluation of individual parameters of selected varieties. For this purpose, a pilot experiment was established in 2019 in the Benešov region in location Netvořice. This area is located in a moderately warm climate area in the area of potato production at an altitude of 390 meters above sea level. Two very early soybean varieties, Amandine and Abelina, were selected for this experiment, which are suitable for these conditions due to their shorter growing season. These varieties were grown in two variants. Control variant without treatment and variant with treatment with Energen Apikál, which increases apical dominance. Each variant and treatment variant was repeated 4 times to obtain the most accurate data. The following parameters were evaluated for both varieties: seed yield, nitrogenous substances content, number of plants per square meter, fat content, weight of a thousand seeds, plant height, number of primary branches, number of pods per plant, number of seeds in the pod and height of first pod. The highest average yield was achieved by the Amandine variety in the treated variant 3.49 t/ha. The Abelina variety achieved a very satisfactory yield of 3.18 t/ha also in the treated variant. In the untreated variant, these varieties also achieved a satisfactory yield. Amandine variety 2.99 t/ha and Abelina variety 3.06 t/ha. Another parameter determined was the nitrogenous substances content. This indicator also showed an increase in nitrogenous substances in the seed in the treated variant in both varieties. A very important monitored parameter was the height of the first pod from the soil surface. Here, after the application of Apikál, the lower floor of the pods increased by approximately a centimeter compared to the control in both varieties (Amandine 10.68 cm and Abelina 11.88 cm). In conclusion, Energen Apikál has a positive effect on both qualitative parameters and the main yield elements, which favorably affects the yield and, together with the higher location of plant pods, also partially minimizes harvest losses.
