Results of Field Trials of Adept and Amino Energy for Crops: Sugar Beet, Flax, Winter Rye, and Lupine

Chernihiv Region

Trial 28

The trial was conducted in the Mena district on an 8-hectare area with sugar beet. The soil was low-humus chernozem, highly leached, sandy-loamy. Fertilizers were applied during sowing. Mass seedlings appeared: with Adept — May 8, with peat compost — May 11. In May, NPK fertilization was applied across the entire plot.

Yield results are presented in Table 26.

Table 26. Effectiveness of Adept for Sugar Beet (Mena District)

As in potato trials, the use of the humic preparation Adept proved more economically effective than peat compost. The conditional net income per hectare with Adept exceeded that from peat compost.

Zhytomyr Region

Trial 29

The trial was conducted in the Luhyny district with sugar beet following a stubble predecessor (rye). The field was plowed in fall and fertilized with peat-manure compost. Adept was applied during pre-sowing treatment. The root crop yield was:

• Peat-manure compost 30–40 t/ha: 42.1 t/ha
• Peat-manure compost 30–40 t/ha + Adept 2 L/ha: 63.7 t/ha

Kherson Region

Trial 30

The trial was conducted on chestnut soils in the Kherson district on a 23-hectare plot. The predecessor was tomatoes. During the growing season, two irrigations of 450–500 m³/ha were performed.

Yield results are presented in Table 27.

Table 27. Effectiveness of Adept with Local Application for Sugar Beet

Adept at a dose of 2 L/ha, applied with seeds, showed effectiveness comparable to 30 kg of ammonium nitrate and 80 kg of superphosphate. With Adept, 0.5–0.6 kg/ha of nitrogen and 0.7–0.8 kg/ha of phosphorus were introduced, whereas with mineral fertilizers — 10 kg of nitrogen and 14–16 kg of phosphorus.

Sugar content in beets was:

• Control: 18.6%
• Mineral fertilizers: 17.8%
• Adept: 19.2%

Adept, unlike mineral fertilizers, increases the sugar content of beets.

Kyiv Region

Trial 31

The trial was conducted in the Makariv district on a 10-hectare area with flax. Fertilizers were applied during sowing.

Yield results are presented in Table 28.

Table 28. Influence of Adept and Amino Energy on Flax Seed Yield (Kyiv Region)

Amino Energy at a dose of 1.5 L/ha showed the highest yield increase. For Adept, the optimal dose is 1.5 L/ha, as the maximum increase per 1 L of fertilizer was achieved at this dosage.

Trial 32

The flax trial was conducted on control field No. 4 in the Makariv district using spring plowing. Fertilizers were applied during sowing by broadcasting.

Yield results are presented in Table 29.

Table 29. Influence of Adept and Amino Energy on Flax Seed Yield (Kyiv Region)

Humic fertilizers showed the best results. The maximum effect was achieved with Adept at a dose of 2 L/ha. The optimal dose for Amino Energy is 1.5 L/ha. The yield increase from manure was 10 times lower than from humic fertilizers.

Poltava Region

Trial 33

The trial was conducted in the Poltava region with a combined sowing of winter rye and lupine for grain using fall plowing. The predecessor was oats. Rye was sown in September, lupine — in mid-April along the rows. Fertilization was applied at a rate of 2 L/ha. The vegetative part of the field with fertilization differed sharply from the control.

A test mowing in mid-July showed:

• Rye green mass yield increased by 66%.
• Lupine green mass yield increased by 2.6 times.

Final grain harvest results:

• Control (no fertilization): rye — 0.5 t/ha, lupine — 0.38 t/ha
• Adept fertilization: rye — 1.2 t/ha, lupine — 0.5 t/ha

Humic fertilizers significantly increase the yield of green mass and grain for rye and lupine. Fertilizing winter crops in spring can be an effective agricultural practice.

Conclusion

Analysis of humic fertilizer trials in various soil-climatic zones of Ukraine demonstrates their effectiveness in increasing yields for sugar beet, flax, winter rye, and lupine.

Effectiveness and optimal doses depend on soil-climatic zones (Table 48).

Table 48. Effectiveness of Humic Fertilizers and Recommended Doses for Sugar Beet, Flax, Winter Rye, and Lupine

Humic fertilizers outperform mineral and organic fertilizers in yield increase. They provide products with low production costs and high transportability. The use of humic fertilizers generates additional income due to accelerated maturation and improved product quality.

Further study is required, taking into account zonal and soil conditions.
