STUDY OF THE INFLUENCE OF THE PURITY OF THE SOWING FROW ON THE YIELD IN CULTIVATION OF MAIZE ON GRAIN

Abstract

Among the great variety of crops grown in the fields today, corn occupies a significant place. The spread of this culture is due to the declared demand for it. Therefore, today corn is becoming one of the leading crops grown in different countries and continents. One of the main processes of growing crops in general technology is to ensure quality sowing. Today, technologies that use all sorts of sensors to monitor the sowing and sowing of crops are becoming more common. Precision Planting and John Deere are one of the main manufacturers of modern sowing equipment. In their arsenal there are a number of systems to ensure optimal sowing, the main of which today are: – seed singulation on vSet sowing machines; – use of Keeton seed clamps; – application of mulching film; – application of the Clean Sweep system; – high-speed sowing of corn using the Speed Tube system; – application of Delta Force system; – application of the vDrive system; – Furrow Jet openers. The efficiency of using the Clean Sweep system during sowing is investigated. Crop residue management has become a very important operation today to maximize profitability. Hard stalks and re-sowing of corn on corn create a fairly high density of residues. The amount of residue can affect the humidity and the rate of warming of the soil in the spring. Plant remains may contain diseases that damage young shoots. Therefore, string cleaners must remove them from the cuttings. If there is enough residue, you can increase the pressure on the cleaners to remove debris. If there are few residues or the soil is too soft, you can relieve the pressure on the cleaners so that they float on top. The study used a new method of analyzing the effectiveness of sowing “Methods of flags”. As a result of the research, the effect on the yield of plant residues remaining in the furrow during sowing was obtained. The conducted researches have established the efficiency of using the clamping force control system of the Clean Sweep post-harvest residue spreaders. Based on the analysis of the research, the weight of cobs during harvesting was calculated and the dependence of friendliness and uniformity of maize seedlings on grain on yield was obtained, which shows crop losses due to delayed emergence of seedlings in each category.
