Épocas de poda e uso da irrigação em figueira 'roxo de valinhos' na região de Botucatu, SP

Abstract

O trabalho teve como objetivo avaliar a poda de frutificação da figueira 'Roxo de Valinhos' em julho, agosto, setembro e outubro, com e sem o uso de irrigação complementar, nos ciclos de 2004/2005 e 2005/2006, em experimento realizado em Botucatu (SP). O delineamento experimental adotado foi o de parcelas subdivididas, com cinco repetições, sendo as parcelas correspondentes aos tratamentos com e sem irrigação e as subparcelas, as quatro épocas de poda realizadas. Foram avaliadas características de crescimento, produtividade e sazonalidade. Pelos resultados, permitiu-se concluir que agosto, com o uso de irrigação complementar, foi o mês mais favorável para a realização da poda da figueira, no município de Botucatu (SP), proporcionando maior crescimento dos ramos, e maiores produtividades médias no ensaio tanto no ciclo agrícola 2004/2005 (5,13 t ha-1), quanto no de 2005/2006 (5,82 t ha-1). Em condições não irrigadas, melhores respostas foram obtidas com poda em julho, agosto e setembro de 2004/05 e julho e agosto de 2005/06. O período produtivo da figueira no município estendeu-se de dezembro a abril, e com o uso de irrigação houve maior número de colheitas e ampliação do ciclo produtivo.

Water requirement and yield of fig trees under different drip irrigation management

“…The best results were obtained for the 2-day irrigation interval treatment, with 223 fruits that attended the industry commercial standards, representing the production of 5.13 kg per plant and estimated yield of 8,554 kg ha -1 (Table 3). This result is similar to the Brazilian national mean of 8,620 kg ha -1 (IBGE, 2013), but inferior to those obtained by TECCHIO (2010) andDALASTRA et al (2009) Irrigation in fig tree crops (mean of both irrigated treatments) promoted a 27% increase in fruit total yield of irrigated plants with 2-day intervals when compared with non-irrigated ones. In all experimental area, the 2-day irrigation intervals in the clayey soil promoted a 47% increase when compared with the non-irrigated sandy clay loam soil.…”

“…HERNANDEZ et al (1994) studied the effect of different irrigation levels on fig trees in the region of Ilha Solteira, São Paulo State, and concluded that the applied levels promoted positive effects on the yield of ripe fruits, total yield, branch length, and length and diameter of ripe fruits, recommending the application of 75% of Class A pan evaporation. LEONEL & TECCHIO (2010), when evaluating the pruning effect, either in the presence or absence of irrigation, from July to October, concluded that the irrigation practice promoted higher harvest numbers and expansion of the production cycle.…”

Phenology and Yield of the ‘Roxo De Valinhos’ Fig Cultivar in Western Potiguar

“…Figure 2 shows that branch diameter was highest at 63 days of evaluation (21.13 mm), indicating maximum growth rate, being of 21.13 mm; taking into account the initial diameter of the branches, there was an increase of 27.35%. Leonel and Tecchio (2010) found average branch length values ranging from 49.01 to 53.99 mm, for not irrigated and irrigated plants, respectively, in the first season. While in the second crop, the average values corresponded to 60.32 and 61.15 mm, without and with the use of irrigation, respectively.…”

Phenology, vegetative growth, and yield performance of fig in Southeastern Brazil

“…In a study with 'Roxo de Valinhos', in the municipality of Botucatu, SP, Brazil, Leonel & Tecchio (2010a) obtained a harvest stage of 91 days in the 2004/2005 cycle, and 132 days in the 2005/2006 cycle, indicating that the cycle length is intrinsically related to climatic factors. In the current study, 'Roxo de Valinhos' obtained a harvest stage of 67 days.…”
