A Contrbution to Determining the Economy Sour Cherry and Plum Shaking

Abstract

Picking sour cherries and plums, compared to other orchard maintenance operations, like cutting, fertilizing and protecting fruit, requires the engagement of a large labor force, much time, and carries high costs, that influence the price of the product heavily. This paper analyzes the possibilities related to the use of a mechanized way of picking, i.e. shaking, showing the advantages of using shakers. Besides the analysis of the shake-off time, this paper also presents the indicators of economic advantages of the application of a tractor-driven fruit shaker for a certain fruit plantation over hand picking. Research has undoubtedly shown the advantage of using shaker over the manual way of picking of fruit.

Ubiranje višanja i šljiva u poređenju sa ostalim operacijama obrade voćnjaka, orezivanja, đubrenja i zaštite voćka zahteva veliko angažovanje radne snage, dugačak vremenski period, odnosno visoke troškove koji se odražavaju i na cenu proizvoda. U radu je analizirana mogućnost primene mehanizovanog načina ubiranja, otresanjem, uz obrazloženje prednosti primene tresača. Osim analize vremena otresanja dati su i pokazatelji ekonomske prednosti primene konkretnog traktorskog tresača voća za određenu plantažu voća u odnosu na ručno branje. Istraživanja su ukazala na prednosti primene tresača u odnosu na ručno branje plodova.
