EXPERIMENTAL ESTIMATES OF PROVIDING SEED FEEDING AREAS FOR STRIP SEEDING WITH A DISC COULTER WITH A DEFLECTOR DISTRIBUTOR
An effective factor in increasing the yield of grain crops has long been considered to provide the sown seeds with the necessary nutrition area when sowing. ideally, the plant's nutrition area should be in the form of a circle with an area of 10 ...25 cm2 without overlapping with the neighboring ones. This distribution of feeding areas means an ideal spread of crops without borders and row spacing. However, in the grain production, the standard crop with a row spacing of 15 cm was spread out, where the seed distribution is artificially limited to a narrow strip where the grain feeding areas overlap. According to experts, this placement of seeds, which has developed historically, is not justified by either the experience of agricultural production or agricultural science. The availability of seeds with the necessary feeding area for row sowing is small - about 15%. At the present time, agricultural science is showing increasing interest in the technologies of ideal spread seeding. But the ideal is not yet obtained due to the lack of appropriate coulters. In these conditions, the band seeding method that closely implements the ideal multiple seeding comes to the fore. We propose a number of designs for single-disc and single-disc coulters for strip sowing, which form a fairly wide furrow up to 100 mm
