“…However, skirting tests performed with prepruners have shown that the overall production of the tree is not affected, while mechanical harvesting is facilitated, problems with soil fungus are reduced and tree microclimate is affected (El-Zeftawi, 1976;Morales & Davies, 2000;Sauls, 2008). Similar results were obtained by Santarosa et al (2010), who tested pruning combined with thinning to regulate size and bearing in orange trees. According to Sauls (2008), bearing can be controlled with mechanical pruning, since using this technique after a year of low yield will potentially become the precursor of a highly productive year.…”

This work compares mechanical pruning followed up by hand pruning versus manual pruning in the case of ‘Fortune’ mandarins. Yield and fruit quality were measured over a three-year period. Two mechanical pruning intensities were tested, these intensities being measured as the width of the row middles left free after mechanical pruning. Although there were differences in biomass and diameter of the branches that were cut, no differences were observed between the two mechanical pruning intensities in terms of yield or fruit quality. In all pruning treatments, fruit size reached the highest category. The pruning treatments consisted in: (i) hand pruning every year, (ii) mechanical pruning followed up by hand pruning every year, and (iii) alternating the two previous methods over the years studied. On analysing the accumulated fruit production of the three years, it can be observed that there were no significant differences in yield when mechanical pruning was alternated with hand pruning over the years. When only mechanical pruning was used for the three years, however, a 22% reduction in yield was observed with respect to the treatment involving hand pruning alone. From the economic point of view, mechanical pruning shortened the time needed to complete the follow-up hand pruning by 13% with respect to just hand pruning, but this reduction in labour does not offset the cost of the mechanical equipment.

“…Also, the frequency of green pruning showed no interaction with nitrogen fertilization (Tables 1 and 2). Green pruning recommended by peach integrated production could be used for other purposes, such as to improve the luminosity and aeration of the canopy, to control excessive vegetative growth, to reduce the incidence of diseases and to facilitate cultural practices (Tutida et al 2007;Tratch et al 2010;Santarosa et al 2013). However, the use of higher intensity of green pruning (CGP) should not be recommended if the purpose was only to improve the quality of the fruit, due to the costs for its implementation.…”

Quality peach produced in fertilizer doses of nitrogen and green pruning

ABSTRACT:The increasing consumer demand for fruit quality justifies the development of researches that combine orchards management and consumers' perception of the quality of the product. The aim of this study was to evaluate the effect of nitrogen fertilization combined with green pruning intensity on fruit quality of 'Chimarrita' from high density peach trees during three consecutive harvest seasons.

“…Nas safras de 2006 e 2007, também não houver diferenças das podas em relação à Testemunha, exceto para poda trienal de 30%, que foi superior aos demais na safra de 2007, correspondendo à terceira safra após sua aplicação. Ao contrário do observado em experimentos realizados por Santarosa et al (2010), em pomares submetidos ao manejo orgânico, onde se verificou uma redução da produção de frutos no ano subsequente à realização da poda, tanto com aplicação de poda leves de 15% quanto de podas severas de 30%.…”

“…Estes fatores fazem da poda uma prática importante tanto para a produção quanto para a qualidade de frutos, principalmente em pomares de citros cujos frutos se destinam ao consumo in natura (SARTORI et al, 2007), sendo considerada uma ferramenta auxiliar para o manejo do pomar, facilitando também os tratos culturais, como tratamentos fitossanitários e a colheita. Entretanto, alguns trabalhos demonstram que a poda não interfere na qualidade dos frutos de tangerineiras (MEDEIROS et al, 2009), nem de laranjeiras com menos de sete anos de idade, conduzidas em sistemas orgânicos de produção (SANTAROSA et al, 2010).…”

RESUMO -A poda de frutificação em citricultura pode ser aplicada com o objetivo de controlar o crescimento vegetativo e promover a formação de novos ramos frutíferos. Neste sentido, o objetivo deste trabalho foi avaliar diferentes regimes de poda manual em pomares jovens de Laranjeiras 'Valência', cultivadas em manejo convencional. Utilizou-se um pomar com espaçamento de 5,0 x 2,5 m, implantado em 2001 no município de Montenegro-RS, Brasil. Os tratamentos, com início em 2004, foram: A -Testemunha (sem poda); BPoda anual de 15%; C -Poda bienal de 15%; D -Poda bienal de 30%; e E -Poda trienal de 30% do volume da copa. O delineamento experimental foi de blocos ao acaso, sendo quatro repetições e quatro plantas por parcela. Foram avaliados o número de frutos, massa total e massa média de frutos nas safras de 2006, 2007 e 2008. Foram avaliados aspectos relativos à qualidade dos frutos, como teor de sólidos solúveis totais (SST), acidez total titulável (ATT) e relação SST/AT. As podas de frutificação não alteraram significativamente a produção total de três safras, nem a qualidade físico-química dos frutos, em pomares de laranjeiras 'Valência' com menos de sete anos de idade, em sistema de manejo convencional. Termos para indexação: Citrus sinensis, manejo, qualidade dos frutos. PRODUCTION AND PHYSICO-CHEMICAL QUALITY OF FRUITS IN 'VALENCIA' ORANGE TREES WITH DIFFERENT PRUNING INTENSITIES AND FREQUENCIESABSTRACT -The pruning in citrus can be applied with the objective to control vegetative growth and renew fruiting branches. This research aimed to evaluate different manual pruning regimes in young orchards of 'Valencia' Orange, grown in conventional management. It was used an orchard with spacing 5.0 x 2.5 m, established in 2001 at Montenegro-RS, Brazil. The treatments, starting in 2004, were: A -control, without pruning; B -annual pruning of 15%; C -biennial pruning of 15%; D -biennial pruning of 30% and E -threeyear 30% pruning of the canopy volume. The experiment had a randomized complete-block design, with four-trees plots and four replications. It was evaluated the number of fruits, total fruit mass production and average weight fruit in the crops 2006, 2007 and 2008. Aspects relating to fruit quality, total soluble solids (TSS), total titratable acidity (TTA) and ratio (TSS/TTA) on juice were assessed. The manual pruning does not alter significantly the cumulative yield of three crops, nor physical-chemical and fruits quality in orchards of 'Valencia' orange under the age of seven, with conventional management system.
