Evolução técnica em olivicultura
Barroso, João; Peça, José; Dias, António; Pinheiro, Anacleto; Santos, Lúcio“O Grande Livro da Oliveira e do Azeite – Portugal Oleícola”, cujo autor-coordenador foi o Comendador Jorge Bohm, tem inserido no tema “Evolução técnica em olivicultura” o capítulo da evolução técnica em olivicultura, em que são abordados os seguintes aspectos: - Tecnologias culturais; - Mecanização; - Importância da rega no olival - Conceitos e prática. Em cada um dos aspectos anteriores são apresentadas as s...
Prototype of a Side-row Continuous Canopy Shaking Harvester for Intensive Oliv...
Dias, António B.; Peça, José Oliveira; Cardoso, Victor; Pinheiro, Anacleto; Souza, Domingos Reynolds de; Falcão, José MariaOlive producing countries invested largely in high density groves (200 to 550 trees per hectare) for which the trunk shaking technology were a no efficient totally mechanized system. Continuous canopy shaking is the obvious approach, in order to increase work capacity but also overcoming the problem of scarce and expensive labour. The equipment available today are adapted over-the-row grape or coffee-beans har...

Peça, José; Dias, António; Cardoso, Vitor; Souza, Domingos; Falcão, José; Pinheiro, AnacletoOlive producing countries worldwide invested largely in high density groves varying from 200 to 550 trees per hectare for which no efficient totally mechanized harvesting methodology and technology is available. Trunk shaking is not an adequate option due to lack of space and intense strain in labour and machinery. Continuous canopy shaking is the obvious approach, not only increasing working capacity but also ...
Long-Term Evaluation of the Influence of Mechanical Pruning on Olive Growing
Dias, António Bento; Peça, José; Pinheiro, AnacletoIn Portugal, olive (Olea europaea L.) groves with the traditional tree density of around 100 trees ha -1, necessitate increasing pruning costs every year. As a result farmers tend to lengthen pruning intervals. With the purpose of studying a mechanised alternative to the expensive, labor-intensive manual pruning practice, the authors established in 1997 field trials with the following three treatments: i) manua...
Máquina para a colheita contínua de azeitona em olivais intensivos
Dias, António Bento; Cardoso, V.; Reynolds de Souza, D.; Falcão, J.M.; Pinheiro, Anacleto; Peça, J.O.A diminuição dos custos de colheita nos olivais intensivos (200 a 550 árvores por hectare) terá de ser encarada como tarefa urgente para que estes olivais possam ser competitivos. Nestes olivais, a técnica tradicional de colheita com vibradores de tronco encontra limitações, como a falta de espaço para o desempenho de equipamentos de recolha associados aos vibradores; mas é sobretudo, devido a ser uma técnica ...
Estudo comparativo do desempenho de três sistemas de colheita mecânica de azeitona
Almeida, Arlindo; Peça, José; Pinheiro, Anacleto; Dias, António; Santos, Luís S.S. dos; Reynolds, Domingos; Lopes, JoãoAo longo de três anos, foi realizado trabalho experimental em olivais com densidades de plantação compreendidas entre 100 e 150 árvores por hectare, utilizando três sistemas de colheita mecânica de azeitona, que permitiram obter resultados de capacidade de trabalho (árvores por hora). Nos três sistemas, para o destaque dos frutos foi usado o mesmo vibrador de troncos. A diferença está na recolha dos frutos derr...
Farmer’s evaluation of a rolling canvas prototype against his own system for ha...
Almeida, Arlindo; Peça, José; Pinheiro, Anacleto; Dias, António; Santos, Luís S.S. dos; Lopes, João; Gomes, JoséAn olive grower was invited to organise a full day harvesting test based on two rolling canvas prototypes, using his own trunk shaker, tractors and labour. This paper reports the results observed, making also a comparison with the usual harvesting method followed by the farmer, based on a trunk shaker and canvas manually placed under the trees. Results show that the rolling canvas based system has got a slightl...
Mechanical harvesting of 400 trees per hectare olive orchards based on a rollin...
Peça, José; Almeida, Arlindo; Pinheiro, Anacleto; Dias, António; Santos, Luís S.S. dos; Lopes, João; Reynolds, DomingosAs the world's olive industries move towards higher densities of trees per hectare, different alternatives are required to collect olives harvested by trunk shakers. This paper puts forward a revised concept of the traingli cart with a rolling canvas system. The equipment consists on a 6 m long box welded to a wheeled chassis, with a rolling canvas system placed over its full length. Olives are stored until the...
Performance of three mechanical harvesting systems for olives in Portugal
Almeida, Arlindo; Peça, José; Pinheiro, Anacleto; Dias, António; Santos, Luís S.S. dos; Reynolds, Domingos; Lopes, JoãoThree mechanical harvesting systems for olives have been tested in field trials in the two main Portuguese regions of olive production: Trás-os-Montes and Alentejo. These tests took place in traditional olive orchards with 100 to 150 trees per hectare. In the three systems, olives were harvested with the same trunk shaker and were collected manually (system I); with a tractor mounted rolling canvas (system II)...
Performance of the “Oli-Picker” olive harvester in Trás-os-Montes region of Por...
Almeida, Arlindo; Peça, José; Pinheiro, Anacleto; Dias, AntónioTrunk and bough shakers are common equipment for olive harvesting. Not surprising information concerning their performance is available. For less usual equipment like canopy shakers, however, there is lack of information relative to their field work. This paper deals with the performance of an “Oli-picker” harvester which is basically a rotor device brushing the canopy, mounted on a structure making possible it...
