Dnipro, Erastovskaya izsledovskaya station. The reaction of the soil solution is neutral, the pH of the water extract is in the range of 6.5-7.0. The content of humus in the arable layer is from 4.0 to 4.5%. Gross content of nutrients: nitrogen from 0.23 to 0.26%, phosphorus from 0.11 to 0.16%, potassium from 2.0 to 2.5%. The nitrification ability of ordinary chernozem is average and high (2.0-3.2 mg N per 100 g of soil). Mobile phosphorus, according to Chirikov, in the arable layer - 7-10 mg per 100 g of soil.

Почва: малогумусный важкосуглинкови черноземы и их слабо смыты разновидности. Реакция почвенного раствора нейтральная, pH водной вытяжки находится в пределах 6,5-7,0. Содержание гумуса в пахотном слое от 4,0 до 4,5%. Валовое содержание питательных веществ: азот от 0,23 до 0,26%, фосфор от 0,11 до 0,16%, калий от 2,0 до 2,5%. Нитрификацийна способность чернозема обыкновенного средняя и повышенная (2,0-3,2 мг N на 100 г почвы). Подвижного фосфора, по Чирикова, в пахотном слое - 7-10 мг на 100г почвы.

Scheme of research efficiency complex mineral fertilizers PARTNER ™ on corn:

Control (without seed treatment and sowing)
Urea (4 kg/ha) in the phase of 5-6 leaves
ENERGY NPK 13.40.13 + AMK + ME (3 kg / ha) in the phase of 5-6 leaves
ENERGY NPK 13.40.13 + AMK + ME (3 kg / ha) Urea (4 kg / ha) in the phase of 5-6 leaves
ENERGY NPK 20.20.20 + AMK + ME (3 kg / ha) Urea (4 kg / ha) in the phase of 10-12 leaves
ENERGY NPK 13.40.13 + AMK + ME (3 kg / ha) Urea (4 kg / ha) in the phase of 5-6 leaves BOR + NPK 9.12.35 + 2B + ME (3 kg / ha) in the phase before panicle shedding
ENERGY NPK 13.40.13 + AMK + ME (3 kg / ha) Urea (4 kg / ha) in the phase of 5-6 leaves ENERGY NPK 20.20.20 + AMK + ME (3 kg / ha) in the phase of 10-12 leaves that the maximum number of plants formed forks on variants with the use of complex fertilizers with an increased content of phosphorus, both in pure form and in a mixture with urea and universal complex fertilizer.

Важным элементом производительности кукурузы является показатель количества початков на растениях.

Так, подсчет початков перед сбором показал, что максимально растения сформировали вилки на вариантах с применением комплексного удобрения с повышенным содержанием фосфора как в чистом виде, так и в смеси с карбамидом и универсальным комплексным удобрением.

The data of the morphological characteristics (the length of the beginning and the number of grains) also showed a direct dependence on complex fertilizers.

An integral indicator of the influence of any agricultural activity is the yield of the crop. The analysis of the obtained yield of corn indicates a significant influence of complex water-soluble fertilizers PARTNER ™ on its level.

Influence of foliar fertilization with PARTNER ™ complex fertilizers on elements of corn productivity, 2017.

Corn yield per grain in 2017 depending on foliar fertilization with PARTNER ™ complex mineral fertilizers, t/ha.

Conclusion

Weather conditions in 2017 in terms of humidity and air temperature were average favorable for the emergence of seeds, growth and development of corn plants, but the dry and hot weather in the summer did not allow to fully realize the genetic potential of plants and to obtain the corresponding productivity of cultivated crops.

The use of complex fertilizers PARTNER ™ on corn crops led to an increase in yield. Spraying plants in the development phase of 5-6 leaves with complex fertilizerPARTNER ENERGY NPK 13.40.13 + AMK + ME contributed to an increase in grain yield by6.5 c/ha (16.2%) compared to the control.
SprayingPARTNER ENERGY NPK 20.20.20 + AMK + ME in the later phase of corn development (10-12 leaves) also turned out to be effective, the average yield increase was5.5 t/ha (13.7%).

The maximum productivity of corn was obtained in variant with double spraying of cropsENERGY NPK 13.40.13 + AMK + ME in the phase of 5-6 leaves andENERGY NPK 20.20.20 + AMK + ME in the phase of 10-12 leaves.
The increase in grain yield compared to the control was8.6 c/ha or 21.4%.
