IMPROVING THE EFFICIENCY OF IRRIGATION OF ARABLE LAND

Abstract

For optimal use of agricultural land, the mechanism of hypocycloidal trajectory of end point system is suggested to be applied in the circular irrigation system. It is found that using of the mechanism of hypocycloidal trajectory of end point irrigation system in the form of a shortened hypocycloid with parameters:
 ratio of the radius of guide circle Rg.circ to the radius of forming circle r is equal
to 4;
 slip coefficient is equal to0.37 ;
 radius of guide circle is equal to 0.76  а, where а - the length of the side of the square, which fits into the trajectory of the Pivots; will provide utilization factor of arable land which is equal to 0.97. Key words: Arable land, technology of circular irrigation, trajectory parameters, shortened hypocycloid
