The effect of the type of preparation with the content of nano-copper and copper on the coverage of winter rape plants
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 4
Abstract
The aim of the study was to determine the average total coverage of winter rapeseed surface sprayed with copper foliar fertilizer and nano-copper and to determine the total plant surface in the three development stages studied (12, 14 and 16 BBCH). Coverage studies were carried out in the "Aporo1" chamber at a speed of 0.86 m·s-1, pressure of 0.20 and 0.28 MPa, using two conventional nozzles for spraying: XR 110-02 and DF 120-02. To determine the size of the coverage, the samplers were used in the form of water-sensitive papers attached to the horizontal and vertical surfaces of artificial plants. The degree of coverage was determined by a computer method of image analysis. To determine the size of the projections of the horizontal and vertical surfaces of the studied plants, they were photographed in each development phase, then they were subject to graphic processing. In Scan2Cad, photos were transformed into a vector image, then using the AutoCad 2014 program, the projection size of the tested surfaces was read. The total surface of plants was determined after determining the size of vertical and horizontal projections of plants. It was found that after use of the DF 120-02 nozzle, a better coverage of the sprayed plants was achieved in each development phase and with all applied spraying parameters compared to the XR 110-02 nozzle. There was no statistically significant effect of the nano-element on the value of average coverage of the surface of the winter rapeseed plants.
