Application of Mind, Adept and Amino Energy fertilizers for cabbage

Experiment 34

An experiment with early cabbage was conducted in the Mensky district of the Chernigov region. The predecessor was cucumbers, under which manure was applied in the amount of 45 t/ha. Humic fertilizers were applied during planting according to the experimental scheme.

The increase in cabbage yield in the variants relative to the unfertilized control was:

• Adept 1 l/ha - 25 c/ha
• Adept 1.5 l/ha - 43 c/ha
• Adept 2 l/ha - 63 c/ha

The highest yield was obtained by applying Adept at a dose of 2 l/ha.

Experience 35

To study the effectiveness of various humic fertilizers, an experiment was conducted with late cabbage. Fertilizers were applied when planting seedlings. The predecessor was cucumbers, for which manure was applied at 45 t/ha.

The results of the harvest accounting are presented in Table 30.

Table 30. Efficiency of humic fertilizers Adept and Amino Energy for late cabbage

Experience shows that cabbage responds well to the Adept humic fertilizer, which contains phytohormones, micromycetes, fatty acids, phosphorus and potassium. The effect of potassium on the yield is especially noticeable. The Mind preparation turned out to be much more effective than humus, providing a multiple increase in yield per 1 liter of fertilizer. The economic profitability of these fertilizers is beyond doubt.

Experiment 36

The experiment was conducted in the Mensky district of the Chernigov region with late cabbage on podzolized chernozem. The experimental area was 0.50 ha. Manure was applied in the spring under plowing at a dose of 25 t/ha, and humic fertilizers were applied during planting at doses of 1.5 and 2 l/ha.

Phenological observations showed that at the beginning of development, cabbage looked better in the variant with humic fertilizers (1.5 l/ha) than in the variant with manure. By the end of the growing season, the difference smoothed out, but a violet-purple coloration of old leaves was observed, indicating a lack of nitrogen and phosphorus. This indicates the possibility of increasing the yield with timely mineral fertilizing.

The results of the experiment are presented in Table 31.

Table 31. Efficiency of Adept humic fertilizers for cabbage

Adept at doses of 1.5–2 l/ha provided a greater yield than 25 t/ha of manure.

Experiments 37 and 38

Experiments with early and mid-season cabbage were conducted in Makarovsky district of Kyiv region on sandy soils. The efficiency of ammonia water and ammonium nitrate was compared. Microelements — boron and magnesium — were tested against the background of these fertilizers.

Fertilizers were applied before planting:

• Humic fertilizers: Amino Energy, Adept, Mind.
• Mineral fertilizers (N20P20K20 per hectare): ammonia water (0.5% solution, 250 ml per hole), phosphorus (phosphate rock), potassium (kainite).
• Boron and magnesium - 1.5 g per well.

The results of the experiments are presented in Tables 32 and 33.

Table 32. Efficiency of humic fertilizers (Adept, Mind, Amino Energy) for early cabbage variety No. 1

Table 33. Efficiency of humic fertilizers (Adept, Mind, Amino Energy) for medium cabbage variety No. 2

Humic fertilizers (Adept, Mind, Amino Energy) were superior to mineral fertilizers in absolute yield increase and cash income. Adept showed some advantages, but the significant effect of potassium makes it difficult to draw final conclusions about the forms of humic fertilizers. Ammonia water was more effective than ammonium nitrate, probably due to the activation of humus in the root zone. A mechanical mixture of peat with mineral fertilizers was less effective than complex humic fertilizers. The addition of boron and magnesium increased the effectiveness of humic fertilizer Mind. The high income is explained by the low yield without fertilizers on sandy soils.

Experiment 39

A production experiment with early cabbage of variety No. 1 was conducted in Cherkassy district on sandy loam podzolized chernozem. The predecessor was pepper. Fertilizers were applied when planting seedlings. After 3–4 weeks, the plants in the variant with Mind (2 l/ha) were twice as tall as the control ones and had a greener color.

The results are presented in Table 34.

Table 34. Efficiency of Mind Agro.Bio for early cabbage

The greatest increase was obtained with the application of Mind (2 l/ha), which exceeded the increase from humus by almost three times. The increase from 4 t/ha of humus is equivalent to 1.5 l/ha of Mind. The highest income and minimum cost were achieved with 2 l/ha of Mind. After planting the seedlings, temporary suppression of plants was observed, which disappeared after rains, indicating the maximum dose of Mind at 2 l/ha. The dose of 0.5 l/ha was ineffective.

Experience 40

The experiment was conducted in Novomoskovsk district of Dnipropetrovsk region with cabbage variety No. 3. The predecessor was tomatoes after perennial grasses, for which 2 c/ha of mineral fertilizers (NPK) were applied. In spring, 20 t/ha of humus were applied for cultivation. Humic fertilizers were applied when planting seedlings. Three irrigations were carried out during the growing season (one by furrows, two by sprinkling).

2-3 weeks after planting, the plants in the area fertilized with Adept Agro.Bio had more leaves and developed leaf blades.

The results are presented in Table 35.

Table 35. Comparative efficiency of Adept and mineral fertilizers for cabbage

Humic fertilizer Adept (2 l/ha) has shown greater efficiency compared to mineral fertilizers.

Experiment 41

The experiment with late cabbage was carried out on ordinary black soil with irrigation in 5-fold repetition. The predecessor was tomatoes. 20-30 t/ha of manure were added under autumn plowing. Fertilizers were added when planting seedlings.

The results are presented in Table 36.

Table 36. Comparative efficiency of humic and mineral fertilizers for late cabbage (2019)

Adept (2 l/ha) gave an increase of 78 c/ha. The low percentage of increase is explained by the high yield in the control. The accuracy of the experiment is 1.21%. Adept (1.5 l/ha) is equivalent to 4 t/ha of humus in increase.

Experiment 42

The experiment was conducted in the Zaporizhia region with late cabbage on ordinary light loamy chernozem with irrigation. The predecessor was potatoes. In the spring, 20 t/ha of manure were added for cultivation. Fertilizers were added when planting seedlings.

The results are presented in Table 37.

Table 37. Comparative efficiency of humic and mineral fertilizers for late cabbage

Adept (2 l/ha) gave an increase of 423 c/ha, twice the increase from mineral fertilizers.

Experiment 43

The experiment was conducted in the Kherson region with early cabbage under irrigation. Manure was applied under autumn plowing. In the spring, when planting seedlings, Adept was applied (1.5–2 l/ha). The yield under control was 615 c/ha, with Adept — 840 c/ha, an increase of 26.8%. Acceleration of development and earlier return of production were noted.

Conclusion

Analysis of tests of humic fertilizers in various soil and climatic zones of Ukraine shows their effectiveness in increasing cabbage yields.

Efficiency and optimal doses depend on soil and climate zones (Table 48).

Table 48. Efficiency of humic fertilizers and recommended doses for cabbage in Ukraine

Humic fertilizers are superior to mineral and organic fertilizers in terms of yield increase. They provide products with low cost and high transportability. The use of humic fertilizers provides additional income due to accelerated ripening and improved product quality.

These issues require further study taking into account zonal and soil conditions.
