Foliar Application With Agrostemin on Potato (Solanum Tuberosum)
Abstract
The main aim of the investigation was to consolidate the influence ofthe diferent doses of agrostemin on the yield on potato.During 2000 and 2001 year in the region of Robovo-Strumica, onalluvial soil with neutral reaction, middle reserve with humus and nitrogen's,rich reserve with phosphorus and potassium, with field examination in threerepetitions, parcel size from 4,2 m2, was made investigation with two dose ofagrostemin, which were aplicated with foliar metod in three times on thevegetation period of potato, sort Jaerla, with interval between treatment from13 to 15 days.From all resarch variants were obtained various results on thequantitative characteristics on potato and they showed that the used doses ofagrostemin influenced positively on the average yield.The best average yield gave variant 3, where was used 4,8 gagrostemin /10 l water in three foliar aplication during the vegetation periodand gave average yield of 47,79 t/ha who comparing with control was more for7,93 t/ha or 19,89 %.References
