Researches of advanced technology of cultivation of corn without application of herbicides with use of new agricultural domestic cars and a rotational mattock which revealed advantages of new technology and its efficiency in comparison with the operating are carried out.
The existing technology demands essential expenses of fuel, energy and means of chemicalixation, therefore corn cultivation on zero technology or with the minimum processing of the soil very actually.
The first experiments on carrying out direct crops of corn in the south of Ukraine are carried out in 1986.
Bottleneck of existing technology was and there is a fight against weeds. Even at modern development of technologies agricultural producers pay to weeds the unreasonable price, spending funds for energy carriers and chemical means of fight against them.
Care of crops in the south of Ukraine is carried out according to two technological schemes: with application of herbicides and without them – by means of soil machining.
Application of chemical means of fight against weeds allows to reduce number of interrow processings and to reduce power consumption of technologies. Costs of herbicides make 15-20 % of all expenses for corn cultivation. However chemical means do essential harm to environment and people. Tape introduction of herbicides allows 70sm to reduce a dose of their expenses for 50 % at width of a row-spacing.
Other technological scheme provides fight against weeds by means of means. Cultivators propashny KRN and KRNV type of national production morally became outdated and don’t meet modern requirements. Considerably modern requirements are answered by a cultivator propashny KRK-5,6.
Today spring harrows of the BPN-12 type of production are widely applied to fight against weeds by means of mechanical means in an initial stage of their development Galishina machine works. Rotational mattock MRN-5,6 has good results on quality of work and productivity. It carries out continuous processing of the soil on depth to 6sm on shoots of propashny cultures and destroys weeds in the phase "threads" that allows to reduce costs of interrow processings, to avoid application of herbicides, and will give the chance to receive non-polluting agricultural products.
Technical characteristics of rotational mattock MRN-5,6
At advanced technology of cultivation of corn agricultural cars are applied to preseeding processing of the soil, crops and care of crops also:
- a cultivator of continuous processing of the soil KPS-8, to class 30kN tractors;
- a seeder propashny 12-ryadny SUPN-12A productions of JSC Chervona z_rka to HTZ-120/121 type tractors;
- rotational mattock MRN-5,6 – designs of the South Ukrainian MIS for care of crops to class 14kN tractors.
As a whole cumulative expenses on separate operations in 1,4 times it is less, than at operating technology. The difference in indicators gave the chance to gain economic effect of application of advanced technology at a rate of 133,1 UAH. on 1 hectare.
