| Popis: | U radu je prikazana usporedba radnih učinaka samokretne platforme „Pluk-O-Trak“ i vučene prikolice u berbi jabuka. Terenska istraživanja i pokusi provedeni su u Kominu (Dolina Neretve) na sortama jabuka Cripps Pink, Fuji Kiku 8 i Granny Smith na površini nasada od 7,3 ha. Gustoća sadnje u nasadu je 2,7 m x 0,6 m, odnosno 6.170 sadnica po hektaru. Rezultati istraživanja su impresivni u pogledu radnih učinaka i kvalitete ubranih plodova jabuka. Današnja tehnologija uzgoja jabuka je poznata, no profit se krije u reduciranju troškova u slučaju primjene vučenih platformi za berbu plodova. Nabavna cijena vučene prikolice, poprilično jednostavne izvedbe je značajno niža u odnosu na samokretnu platformu, a da pri tome nema bitnije razlike u radnim učincima i kvaliteti ubranih jabuka. Tako se trošak berbe kod primjene samokretne platforme kreće od 0,80 - 0,90 kn/kg, a kod vučene prikolice svega 0,10 - 0,14 kn/kg ubrane jabuke. U kalkulaciji troška berbe je osim troška radne snage-berača uključena i amortizacija platforme i prikolice. Primjenom strojne rezidbe jabuke i prikolica za berbu moguće je svesti trošak proizvodnje jabuke u rasponu od 1,35 – 1,50 kn/kg. The paper compares the performance data of “Pluk-O-Trak” self-propelled fruit harvesting machine and towed harvesting platform in apple harvest. Field studies and experiments on Cripps Pink, Fuji Kiku 8 and Granny Smith apple cultivars were carried out in Komin (Neretva Valley) orchards, totalling 7.3 ha. The tree density in orchards was 2.7 m x 0.6 m, i.e. 6,170 seedlings per hectare. In terms of measured performance and the quality of harvested apple fruit, the results of our research were impressive. Despite current apple growing technology being well known, the profit lies in reducing costs by using a towed fruit harvesting platforms. The purchase price of a fairly simple towed platform is significantly lower than self-propelled harvesting machine, without significant difference in their performance and the quality of harvested apples. The cost of harvest using a self propelled harvesting machine thus amounted to 0.80 – 0.90 EUR/kg, while the cost of harvest using a towed harvesting platform amounted to only 0.10 – 0.14 EUR/kg of harvested apples. In addition to labour costs (pickers), the calculation of harvesting costs also included the depreciation of self propelled harvesting machine and towed harvesting platform. Mechanical pruning and towed harvesting platforms may reduce the cost of apple production from 1.35 to 1.50 EUR/kg. |
