Winter rape - a culture that is mainly export oriented, provides the first proceeds from the crop production industry to growers. Despite the rather substantial cost of resources for its cultivation, culture almost always provides profit. During the entire period of vegetation it is important to provide plants with macro and microelements. The trace elements and biologically active substances, if necessary, are better to use the method of non-root nutrition. Among the technological means that ensure successful hibernation of plants, the formation of the size and quality of the crop - there are fertilizers for non-root nutrition.
In the growing season of winter rape from 2017 to 2018, we studied the effect of extra-root nutrition by special fertilizers manufactured by the company EKORORGANIK on the production of the crop depending on the soil-climatic conditions, the level of resource support, the terms of sowing. The experimental plots of industrial crops were located in the Dnipropetrovsk and Nikopol districts of the Dnipropetrovsk region. Farms differed in terms of providing moisture, resource support for growing technology.
On the field of SFG "Niva 1" located in the Nikopol district, a comparative test was carried out of the system of foliar fertilization adopted by the farm and proposed by the company "EKORRGANIK". Scheme of the experiment included: Staging phase - ECOLINE Phosphite (K) 1.0 l / ha; Budionization - Ecoline Bohr (Premium) 1.0 l / ha + Gross Quicheilium 1.0 l / ha; Beginning of the formation of pods - ECOLINE Oliyiny (Chelaty) 1.0 l / ha.
The interim records made by us in this field (Table 1) showed the advantage of the system of foliar growing of winter rape from OOO "EKORRGANIK" in comparison with the adopted on the farm.
|Options||Height of one plant, see||Average weight of one plant, g||Number of branches per plant, pcs|
|Control - the scheme of the economy||118||392||6.4|
|Scheme from OOO "EKORGANIK"||120||937||8.8|
|+ to control||+2||+545||+2.4|
Winter canola plants in the beginning of May in the version with foliar feedings from "ECORGANIK" LLC had a significant advantage over key parameters such as the mass of plants and the number of branches per plant, which is also visible in the photo.
The feeding schemes and harvesting results are shown in Table 2.
|Phase of plant development||Economy option||Option ECORGANIC|
|Stem||Spectrum Mn + Zn 1 l / ha||ECOLINE Phosphite (K) 1.0 l / ha|
|Budionization||Spectrum Mo + B 2 l / ha||Ecoline Bohr (Premium) 1.0 l / ha + GROS Quichelium 1.0 l / ha|
|Beginning of forming pods||Spectrum Mo + B 2l / ha||Ecoline Oil (Helatas) 1.0 l / ha|
|Yield, c / ha||29.8||32.4|
|Growth, c / ha||2.6|
Harvest harvest records confirmed preliminary results. The yield increase in the variant with the system of foliar feeding from OOO "EKORRGANIK" was in absolute terms 2.6 c / ha, or 9.3% compared with the control system - the system of foliar growing of winter rape accepted at the farm.
Experienced company "EKORRGANIK" at the farm TD "Demetra"
The second economy of TD "Demetra" is located in Dnipropetrovsk region. The field on which the winter rape was sown was part of the irrigated land of vegetable crop rotation with good agrochemical and physico-chemical characteristics. The farm in the agricultural sector is quite powerful and uses intensive cultivation technologies.
The main supply system in the Demetra TD during the cultivation of winter rape was as follows: under pre-sowing cultivation - 200 kg of nitroamophos, on the permafrost soil 300 kg / ha of ammonium nitrate; two weeks 160 kg / ha of ammonium sulfate - the start of budding.
The experimental scheme of the company "EKORRGANIK" included:
Phase of budding - Ecoline Bohr (Premium) 1.0 l / ha + Ecoline Phosphite (K) 1.0 l / ha;
Beginning of flowering - ECOLINE BOR (Premium) 1.0 l / ha + ECONAL Magnesium (Helatas) 1.0 l / ha;
The development of pods - ECOLINE Oliyiny (Chelaty) 2.0 l / ha.
|Version||Weight of plants, g||Plant height, see||Average number of branches per plant, pc|
|OPTION FOR ECORGANIC||680||125||12|
|+ before control,%||+ 109||+ 112||+ 145|
Even in the conditions of a powerful main fertilizer by macronutrients, foliar nutrition contributed to the formation of more powerful plants in terms of height, mass and number of phytoplanktonic branches. The appearance of the plants from the control and experimental options is clearly visible in the photo.
At the beginning of the roasting of seeds in a pod was conducted a second intermediate account, the results of which are given in Table 4.
|Version||Weight of plants, g / m2||Average number of branches per plant, pc||Weight of pods, g / m2|
|+ before control,%||+ 117||+ 145||+ 112|
According to the records, the positive tendency for the production of rape crops was maintained and further, confirming the results of harvesting (Table 5).
