“…This reduction in peach yield was anticipated because other studies indicate similar negative RDI effects that are explained by a decrease in nutrient uptake and photosynthetic yield due to stomatal closure and reduction of the number of leaves, resulting from the decrease in shoot growth [16,39] . However, contrasting results have been reported from other studies, indicating that RDI applied to peach during Stage II did not affect fruit yield even under stress levels up to 35% ETC [40,41] . These results have been explained by the low water requirements of peach trees during Stage II to satisfy normal fruit growth without accentuating their fall, thereby maintaining fruit yield.…”

The effects of regulated deficit irrigation (RDI) on the performance of almond cv. Tuono, peach cv. JH-Hall and plum cv. Stanley were assessed on the Saiss Plain (NW, Morocco) over three consecutive growing seasons (2011-2013). Irrigation treatments consisted of a control, irrigation applied to fully satisfy crop water requirements (100% ETC), and two RDI treatments, irrigation applied to 75% ETC (RDI-75) and 50% ETC (RDI-50). These three treatments were applied during fruit-growth slowdown periods corresponding to Stages II and III in almond and Stage II in peach and plum. Yield and fruit quality traits were determined. The effect of RDI differed between species. Yield and fruit size were reduced significantly only in peach under RDI-50. Fruit quality improved in this species in the first year of the experiment, with an increase of sugar/acid ratio and polyphenol content. Plum quality also improved but the effects were significant only in the second and third years. Similar results were recorded in almond kernel, but their epidermal grooves were deeper under RDI-50, and this may have affected their commercial value. It is concluded that water can be saved during the fruit-growth slowdown period by up to 25% in peach and 50% in almond and plum with improvements in fruit quality without affecting total yield.

“…Production benefi ts of drip may also lie in the response of peach to restricted root volumes (Boland et al, 2000a(Boland et al, , 2000b. Root systems are typically confi ned by drip because it wets only a fraction of the soil volume wetted by other systems (Mitchell and Chalmers, 1983).…”

A 3-year study was done to determine the effects of furrow, microspray, surface drip, and subsurface drip irrigation on production and fruit quality in mature `Crimson Lady' peach [Prunus persica (L.) Batsch] trees. Furrow and microspray irrigations were scheduled weekly or biweekly, which is common practice in central California, while surface and subsurface drip irrigations were scheduled daily. Trees were maintained at similar water potentials following irrigation by adjusting water applications as needed. Tree size and fruit number were normalized among treatments by pruning and thinning each season. Surface and subsurface drip produced the largest fruit on average and the highest marketable yields among treatments. Drip benefits appeared most related to the ability to apply frequent irrigations. Whether water was applied above or below ground, daily irrigations by drip maintained higher soil water content within the root zone and prevented cycles of water stress found between less-frequent furrow and microspray irrigations. With furrow and microsprays, midday tree water potentials reached as low as –1.4 MPa between weekly irrigations and –1.8 MPa between biweekly irrigations, which likely accounted for smaller fruit and lower yields in these treatments. To reduce water stress, more frequent irrigation is probably impractical with furrow systems but is recommended when irrigating during peak water demands by microspray.

Tamaño de contenedor y tipo de sustrato afectan la eficiencia en el uso del agua en Gerbera jamesonii para flor cortada (¹) LIBERTAD MASCARINI (2) ; GABRIEL LORENZO (2) ; HECTOR SVARTZ (2) ; SABRINA PESENTI (2) ; SILVIA AMADO (2) (1) Recebido em 04/02/2010 e aceito para publicação em 09/08/2011.(2) Facultad de Agronomía -Universidad de Buenos Aires. Avenida San Martín 4453 (1417) Ciudad Autónoma de Buenos Aires, Argentina RESUMENSe probaron dos tamaños de contenedor (macetas de 4 y 8 L) y tres mezclas de sustrato (% de turba/perlita 0/100, 25/75 y 50/50) con el objetivo de determinar la combinación óptima para el cultivo de gerbera para flor cortada, considerando la productividad comercial (cantidad y calidad de flores) y el impacto ambiental (eficiencia en el uso del agua y fertilizantes). La mejor combinación en el primer año de producción fue macetas de 8 L con sustrato 0/100, seguido de los contenedores de 4 y 8 L con 25/75, con un rendimiento de 53.4 , 30.5 y 29.7 flores./m-2 respectivamente. El resto de los tratamientos tuvo un rendimiento similar de alrededor de 20 flores m-2. La calidad comercial de las flores cortadas fue aceptable en todos los tratamientos. En cuanto a la eficiencia medida como agua consumida por flor cosechada, el tratamiento 8 L 0/100 resultó claramente superior con un valor de 1.23 L/flor, el resto de los tratamientos estuvieron entre 2.17 y 4.14 L/flor, guardando relación tanto con el tamaño de contenedor como con el tipo de sustrato utilizado. La importancia de estos resultados es la consideración simultánea de los factores que hacen a la rentabilidad comercial y al desarrollo de tecnologías sustentables para los cultivos intensivos.

ABSTRACT Container size and growing media affects water use efficiency in a Gerbera jamesonii cut flower cropTwo containers (4 and 8 L plastic pots) and three growing media mixture types (0/100, 25/75 and 50/50 % of peat/perlite) were used, with the aim of determining the optimum combination for gerbera cut flower crop, considering both commercial productivity (yield and quality of cut flowers) and environmental impact, (water and fertilizer use efficiency). The best combination in the first year of production was 8 L and 0/100, followed of 4 and 8 L with the 25/75, with a yield of 53.4, 30.5 and 29.7 flowers m-2 respectively. The yield of the rest of the treatments were similar, around 20 flowers m-2. Commercial cut flower quality was aceptable in all treatments. Considering the efficiency measured as the ratio water used per flower harvested, 8L 0/100 was clearly superior with a value of 1.23 L/flower, the rest of the treatments were between 2.17 y 4.14 L/flower, keeping relation as much with container size like with growing media mixture. The importance of these results is the simultaneous consideration of many factors which affect both comercial profitability and development of sustainable technology for intensive crops.
