Abstract

Field experiments were carried out in the Experimental Farm of Agricultural Production and Research Station (APRS), National Research Centre (NRC), Nubaria Province, El-Behaira Governorate, Egypt. The effect of the use of different speeds in (rpm) and operating period in (min) on harvest productivity and damage percent were evaluated. The main objective of this study is to design and evaluate hand-held harvester for olive. This work describes the complete design of an olive harvesting machine especially conceived for secular olive plants with the purpose of increasing the mechanization level of the harvest operation and permitting the production of high quality fruits.
Using the portable machine for olive harvest, which was designed, it was found that in the three cases using it without spraying and using spraying after a week and spraying after two weeks, the production of harvesting of the machine was the best using the speed of 1600 rpm followed by the speed of 1250 rpm and finally the speed of 900 rpm. Variety of Kornakey was the most responsive to harvest the next god the brand Shamlalli and finally Bikool The percentage of damage was the highest ratio using the fastest speed 1600 rpm and followed by 1250 rpm and finally the speed 900 rpm was the least response to the damage Bikool followed by the Shamlalli and finally Kornakey. This can be summarized by noting that the productivity of the harvest increases with this machine and the percentage of damage is increased as the speed increases.
