“…For citrus fruit, it is commonly known that deficit irrigation applied during the first stage of fruit development (stage II as defined by Bain, 1958), increases total soluble solids (TSS) and decreases acid levels (TA) at maturation (Treeby et al, 2007). Nevertheless, our results showed that there were no effects of water restriction in TSS levels neither in 2007 nor in 2008 which were very similar in all treatments.…”

An experiment on regulated deficit irrigation (RDI) was performed during two growing seasons (2007 and 2008) in a drip-irrigated orchard of Navelina/Cleopatra in Senyera (Valencia, Spain). Two RDI treatments, where water application was reduced to 40% and 60% of the «irrigation dose» (ID), were carried out during the initial fruit enlargement phase (Stage II, 17 th July to 2 nd September). The rest of the year they were irrigated at 110% ID. These treatments were compared with a control, where irrigation was applied without restriction during the whole year at 110% ID. The ID was obtained from the evapotranspiration data, as well as from the characteristic variables of drip irrigation for the specific experimental orchard. The effects of the treatments on yield, fruit quality, and vegetative growth are discussed in relation to tree water status (midday stem water potential, Ψ st ). Minimal Ψ st values reached in the treatment with the highest stress intensity were -1.71 and -1.60 MPa in 2007 and 2008 respectively. These Ψ st values reached as a consequence of the water reduction in the RDI summer treatments applied in this study did not affect yield or fruit quality, allowing water savings between 16% and 23%. In conclusion, water restriction during summer, and once «June drop» has finished, favours the better use of water resources by Navelina citrus trees, achieving an increase of water use efficiency (between 14% and 27% in this case), provided that an appropriate irrigation in autumn allows for tree recovery.Additional key words: citrus trees; drip irrigation; Navelina; stem water potential; water relations; water use efficiency. ResumenEfectos del riego deficitario controlado sobre el crecimiento, producción y calidad de la fruta en cítricos de la variedad Navelina Se ha realizado un experimento de riego deficitario controlado (RDC) durante 2007 y 2008 en una parcela de Navelina/Cleopatra regada por goteo en Senyera (Valencia, España). Se aplicaron dos tratamientos RDC al 40 y 60% de la dosis de riego (ID) durante el periodo de crecimiento inicial del fruto (Fase II, 17/07 al 02/09). El resto del año se regaron al 110% de la ID. Estos tratamientos se compararon con un control, regado todo el año al 110% de la Dr, determinada a partir de la evapotranspiración, así como de los parámetros característicos del riego por goteo de la parcela de ensayo. Los efectos de los tratamientos sobre la producción y calidad de la cosecha, así como sobre el crecimiento vegetativo, se discuten en relación al estrés hídrico producido (potencial del tallo al mediodía solar, Ψ st ). Los valores mínimos de Ψ st alcanzados por el tratamiento más estresado fueron de -1.71 y -1.60 MPa en 2007 y 2008 respectivamente. Estos valores de Ψ st alcanzados como consecuencia de la reducción del riego en los tratamientos RDC en verano aplicados en este trabajo, no produjeron mermas en la producción ni en la calidad de la cosecha, permitiendo ahorros de agua entre el 16 y el 23%. Se concluye que la reducción del riego en verano, tra...

“…percentage reached 96.8%, fruits with 3.9 cm diameter, 0.7 cm thick arils, individual fruit weight of 38.3 g and a yield of 296 kg for tree. In "Fortune" mandarin trees, Dell'Amico et al [14] observed that plants subjected to water stress increased 21.35% more fruits per plant than the plants managed with sufficient irrigation; however, in other studies with citrus fruits, it has been observed that limited irrigation conditions are responsible for a greater number of smaller fruits given their lower average weight and lower final diameter [15]. The trees with girdling, the variables no showed effect, although there was an effect on flower percentage, fruit diameter, shelf-life, and kilograms per tree.…”

Rambutan growing in the state of Chiapas has brought about a demand for new plantations; however, this species has several biotic and abiotic factors that limit its production. These factors include phytosanitary problems, deficient agronomical handling, and production alternancy. Because of this, the objective of the present study was to evaluate the effect of the application of agronomical practices such as pruning, ringing, water stress, and their interaction on the rambutan alternancy. The experiment was carried out in the "La Chinita" commercial orchard located on KM. 4.5 the Huehuetan Station, municipality of Huehuetan, Chiapas, Mexico. We used 48 rambutan trees in production with an age of 14 years. Two production cycles were evaluated. The experiment was established under a divided plot experimental design in random complete blocks with a factorial arrangement and six replicates; each tree being a replicate. The study factors were: water stress, pruning, girdling, irrigation (control), and their combinations, resulting in eight treatments. The evaluation was done during flowering, fruit set, and harvest. In flowering, the treatments with permanent irrigation in both evaluated cycles (2010-2011 and 2011-2012) manifested a production alternancy behavior, with an average 36.4% flowering in the first evaluation cycle and increased to 82.1% in the second cycle. The treatments with water stress kept a proportional flowering during the first and second cycles of 97.9% and 95.3%, respectively. The water stress influenced the bunch weight (PR) variable fruit set with bigger fruits and higher bunch weight than the irrigated treatments. In production, pruning and girdling together with water deficit had no alternancy in both production cycles.

“…Em trabalhos desenvolvidos por Alves Júnior (2006), em pomar de lima ácida 'Tahiti' com quatro anos de idade, não foi observada diferença na produtividade de frutos, diâmetro de frutos e espessura da casca, quanto aos níveis de irrigação de 25, 50, 75 e 100% da evapotranspiração de referência. No entanto, estudos com a técnica de PRD, com uso de deficit de 40 a 50% da ETc, constataram reduções do diâmetro e peso médio de frutos em tangerina (Kirda et al, 2007) e laranja-de-umbigo (Treeby et al, 2007). Contudo, nesses estudos, o tratamento com deficit hídrico com irrigação fixa a um dos lados das plantas teve resultados semelhantes aos tratamentos de deficit com PRD.…”

Resumo -O objetivo deste trabalho foi avaliar o efeito do deficit hídrico associado ao secamento parcial do sistema radicular ("partial rootzone drying", PRD) na produção e eficiência de uso de água, em pomar de lima ácida 'Tahiti', na Região do Semiárido baiano. Utilizou-se o delineamento de blocos ao acaso, com seis tratamentos e seis repetições. Os tratamentos com PRD foram realizados pela alternância periódica (7, 14 ou 21 dias) dos lados em que o microaspersor localizava-se em relação às plantas. Esses tratamentos foram conduzidos com lâmina d'água equivalente a 50% da evapotranspiração da cultura (ETc) e comparados ao tratamento com deficit hídrico de 50% da ETc com microaspersor fixo em um dos lados das plantas, e ao tratamento 100% da ETc, com aspersores de ambos os lados das plantas. Avaliou-se também o PRD (21 dias) com diminuição da irrigação em 25% da ETc. O PRD com 50% da ETc não difere do tratamento com esse mesmo deficit e sem alternância de lados da irrigação, em termos de produtividade, eficiência do uso da água, e diâmetro e peso dos frutos, independentemente do período de alternância dos lados de irrigação. O PRD com diminuição da irrigação em 25% da ETc não causa perdas em relação à condição sem deficit e sem localização da irrigação.Termos para indexação: Citrus latifolia, citros, eficiência de uso de água, limão Tahiti. Water deficit and partial rootzone drying in an acid lime orchardAbstract -The objective of this work was to evaluate the effect of water deficit and of partial rootzone drying (PRD) on the yield and water use efficiency in a 'Tahiti' lime orchard, in the Semiarid Region of Bahia state, Brazil. The experiment was carried out in a randomized block design, with six treatments and six replicates. Treatments with PRD were carried out by the periodic alternance (7, 14 or 21 days) of the sides in which the micro sprinklers were located in relation to the plants. These treatments were performed with a water depth equivalent to 50% of crop evapotranspiration (ETc). They were compared to the treatment with 50% water deficit, using one fixed micro sprinkler at one of the plant sides, and to the treatment at 100%, with sprinklers at both plant sides. PRD (21 days) with 25% ETc water depth reduction was also evaluated. PRD at 50% ETc do not differ from the treatment with this same water deficit and without alternating irrigation sides for productivity, water use efficiency, and fruit diameter and weight, regardless of the irrigation alternating period. PRD with 25% ETc water depth reduction do not cause losses in comparison to the condition without deficit and without localized irrigation.
