Abstract(s)
O estágio decorreu na Herdade das Casas Velhas, na freguesia de Vila Fernando,
concelho de Elvas. Consistiu no acompanhamento das operações culturais realizadas
entre fevereiro e julho de 2023 em duas parcelas de olival em sebe, plantadas em 2020,
uma com a variedade ‘Arbequina’ (9,5 ha) e a outra com a variedade ‘Koroneiki’ (6,0
ha). Foram acompanhadas as operações da poda, do controlo da vegetação do solo, da
rega, da fertilização e dos tratamentos fitossanitários. Adicionalmente foram feitas
observações da fenologia, seguindo a escala BBCH, do período de floração, da qualidade
da flor e da taxa de vingamento das inflorescências. A poda teve como objetivo limpar a
base da sebe, para facilitar a colheita com máquina automotriz, tendo também sido
eliminados ramos que cresciam em direção á entrelinha. As fertilizações e os
tratamentos fitossanitários foram feitos num esquema fixo que nos pareceu pouco
específico para os olivais da Herdade, após indicação tardia da empresa que presta apoio
técnico. A instalação de 2 sondas Wartermark permitiu verificar que, mesmo após duas
alterações das dotações da rega, o teor de humidade do solo era inferior ao desejável,
situação mais crítica na variedade ‘Koroneiki’ onde um solo mais ligeiro requeria uma
gestão da rega diferente. Nas próximas campanhas será requerida mais informação sobre
os resultados das análises do solo e foliares para participação conjunta, com a empresa
de apoio técnico, nas decisões de fertilização. Os tratamentos fitossanitários também
deverão se ajustados à estimativa de risco para este local específico e realizados seguindo
os princípios da proteção integrada. Deverão ser instaladas mais sondas nas outras
parcelas de olival e a gestão da rega deverá ser consoante as leituras Verificou-se que a
variedade ‘Arbequina’ é mais precoce que a ‘Koroneiki’, e, esta variedade também
apresenta uma maior percentagem de flores perfeitas e uma maior taxa de vingamento
inicial e final.
The internship took place at Herdade das Casas Velhas, in the parish of Vila Fernando, in the municipality of Elvas. It consisted of monitoring the cultural operations carried out between February and July 2023 on two plots of hedged olive groves, planted in 2020, one with the 'Arbequina' variety (9.5 ha) and the other with the 'Koroneiki' variety (6.5 ha). 0 ha). The operations of pruning, soil vegetation control, irrigation, fertilization and phytosanitary treatments were monitored. Additionally, observations were made of the phenology, following the BBCH scale, of the flowering period, of the flower quality and of the fruit setting rate. The purpose of pruning was to clean the base of the hedge, to facilitate harvesting with a self-propelled machine, also eliminating branches that grew towards the interlines. Fertilization and phytosanitary treatments were carried out in a fixed scheme that seemed to us not very specific for the Herdade's olive groves, after a late indication from the company that provides technical support. The installation of 2 Wartermark probes made it possible to verify that, even after two changes in the irrigation allocations, the soil moisture content was lower than desirable, a more critical situation in the 'Koroneiki' variety where a different soil required a different irrigation management. In future campaigns, more information will be required on the results of soil and foliar analyses for joint participation, with the technical support company, in fertilization decisions. Phytosanitary treatments should also be adjusted to the risk estimate for this specific location and carried out following the principles of integrated protection. More probes should be installed in the other olive grove plots and irrigation management should depend on the readings It was found that the 'Arbequina' variety is earlier than the 'Koroneiki', that the percentage of perfect flowers is also higher in this variety and which presents higher rate of initial and final setting.
