TThe effect of four levels of saline irrigation (ECi of 0.1 dS m-l, 0.25 dS m-l, 0.5 dS m-l and 1-0 dS m-l) in conjunction with restricted irrigation volumes was studied in drainage lysimeters over 2 years on peach trees (Prunus persica, L. Batsch), 3-years-old in Year 1. Strong negative linear responses to saline irrigation were measured for growth and final fruit size in Year 2. Leaf chloride increased over time and with treatment levels, reaching a maximum of 3.0% for the 1.0 dS m-l treatment at harvest in Year 2. Root weighted soil Na and Cl levels increased with increasing irrigation salinity. Both Na and C1 levels in fruit and wood were increased by saline irrigation. Photosynthesis was reduced at the high ECi level consistent with decreased conductance and likely C1 toxicity. Saline irrigation reduced tree water use (TWU). Leaf chloride was determined to be a good indicator of salinity level and expected yield reduction. The need for leaching and modification of current Regulated Deficit Irrigation (RDI) management is proposed.

The effect of salinity and shallow water tables (1.4 m depth) used in combination with Regulated Deficit Irrigation (RDI) on peach trees (Prunus persica, L. Batsch) was studied over 2 years. Under RDI management a non-saline water table contributed up to 30% of water use. A lack of control of vegetative growth in the first season indicated that a shallow water table may interfere with RDI management. A decline in tree health and growth under RDI and a non-saline water table in the following season may have resulted from salinity and/or waterlogging effects. Saline irrigation under RDI management caused an additional decline in tree growth compared with RDI under non-saline conditions, and resulted in a reduction in productivity (yield and fruit size) and increased uptake of sodium (Na) and chloride (Cl) ions in various plant tissues. Similarly, a saline water table caused a decline in tree growth and fruit size in the first season and increased uptake of Na and C1 ions. For all treatments, accumulation of C1 in the leaves, Na and C1 in the fruit, Na in the bark and storage of Na in the butt wood and structural roots was demonstrated. Differences in mechanisms of transport of Na and C1 and the importance of older wood as a storage organ for ions are proposed. The potential for butt wood as a precise indicator of past salinity treatment is suggested. A combination of a shallow water table and moderate salinity environment was shown to present a potential health hazard for peach trees. The need for refinement of RDI management to incorporate leaching in the presence of saline irrigation and/or water tables is proposed. The management of drainage is also essential.

O experimento foi conduzido no quarto ciclo de produção de bananeiras ‘Grande Naine’, ‘Galil-18’ (FHIA-18), ‘BRS Platina’, ‘Prata-Anã’ e ‘BRS Princesa’. A irrigação com déficit controlado (RDI) de 70 e 50% da evapotranspiração da cultura (ETc) foi realizada em um, dois ou três períodos de julho de 2016 a julho de 2017. Independentemente das cultivares, a altura da planta foi reduzida quando aplicado dois déficits de 50% da ETc, já a área foliar aumentou quando aplicados RDI em um período, RDI com 70% da ETc em dois períodos e RDI com 50% da ETc em três períodos. A RDI de até 50% da ETc em três períodos durante o ciclo da cultura não causa redução na produtividade em nenhuma cultivar avaliada, comparada à irrigação plena. A RDI com 70% da ETc em apenas um período, entre novembro e fevereiro, período chuvoso, possibilitou maior produtividade e maior eficiência de uso da água na ‘Grande Naine’, formando mesmo agrupamento com a ‘BRS Princesa’ e a ‘Prata-Anã’.   Palavras-chave: Musa spp., manejo da irrigação, semiárido.     COELHO, E.

PRODUCTION AND WATER USE EFFICIENCY IN BANANA CULTIVARS UNDER REGULATED DEFICIT IRRIGATION     2 ABSTRACT   This work aimed to evaluate the productivity, water use efficiency and fruit size of different banana cultivars under regulated deficit irrigation in the north of Minas Gerais. The experiment was conducted in the fourth cycle of banana production ‘Great Naine’, ‘Galil-18’ (FHIA-18), ‘BRS Platinum’, ‘Prata-Anã’ and ‘BRS Princesa’. Regulated deficit irrigation (RDI) of 70 and 50% of crop evapotranspiration (ETc) was conducted in one, two or three periods from July 2016 to July 2017. Regardless of cultivars, plant height was reduced when two 50% ETc deficits were applied, whereas leaf area increased when RDI was applied in one period, RDI with 70% ETc in two periods and RDI with 50% ETc in three periods. RDI of up to 50% of ETc in three periods during the crop cycle does not reduce yield in any evaluated cultivar compared to full irrigation. The RDI with 70% of ETc in only one period, between November and February, rainy season, enabled higher productivity and greater water use efficiency in ‘Grande Naine’, forming even grouping with ‘BRS Princesa’ and ‘Prata- Anã’.   Keywords: Musa spp., irrigation management, semi-arid.

Individual and interactive effects of restricted root volume (RRV) and regulated deficit irrigation (RDI) on productivity and water use of peach trees [Prunus persica (L.) Batsch `Golden Queen'] were studied over 3 years (1992-95). Trees were grown in lysimeters of five different soil volumes (0.025, 0.06, 0.15, 0.4, and 1.0 m3) with either full or deficit (RDI) irrigation. In Years 3 and 4, fruit size was reduced by up to 30% on trees in the two smallest volumes. Tree water use was positively related to increasing soil volume (linear, P < 0.001; quadratic, P < 0.011) in all years ranging from 1.8 to 4.4 L·mm-1 Epan in the post-RDI period of Year 2. Water use of deficit-irrigated trees was less than fully irrigated trees and there was an interaction between soil volume and irrigation treatment during RDI. Water relations did not limit growth or productivity. Tree water use was reduced under root restriction as a consequence of canopy demand rather than leaf function. Results suggest that a combination of restricted root volume and development of water stress achieve the RDI response in the Goulburn Valley, Australia.

Early performance (6–8 yr) of Macspur McIntosh, Golden Delicious, and Spartan apple (Malus domestica Borkh.); Fairhaven peach [Prunus persica (L.) Batsch.]; Montmorency sour cherry (P. cerasus L.); and Lambert sweet cherry (P. avium L.) trees, tissue cultured (TC) on their own roots, was compared with that of the same cultivars budded on commercially used rootstocks. TC trees of all apple cultivars were similar in size to trees budded on Antonovka seedling or M.4 and exceeded the size of trees budded on M.26. They were delayed in flowering and in cropping compared with trees budded on M.26 and M.4. No difference in titratable acidity, soluble solids, flesh firmness, weight, flavor, and color between fruit from TC trees and from trees on M.4 and Antonovka seedlings was detected in 1 yr of measurement. However, fruit from TC Golden Delicious was more russeted and fruit from TC Spartan had more soluble solids. The difference in fruit appearance between TC and budded trees may result from a root-stock effect or a difference in budwood source, because Spartan fruit from trees on M.4 was more russeted than Spartan fruit from TC trees, but was not different from Spartan fruit from trees on Antonovka seedling. Trees of Macspur McIntosh on TC M.26 and on stool-layered M.26 were similar in size and yield efficiency. TC Fairhaven was larger in size than Fairhaven on Siberian C seedling, but was less yield efficient. No difference in fruit size, flesh firmness, or color was detected between fruit harvested from peach trees on the different roots. Montmorency and Lambert TC and on F12/1 were similar in tree size, respectively, but Montmorency and Lambert TC were more yield efficient than on F12/1. Fruit of TC Lambert was lighter in color and had higher titratable acidity than that of Lambert on F12/1, perhaps a result of earlier fruit maturity.

Individual and interactive effects of restricted root volume (RRV) and regulated deficit irrigation (RDI) on vegetative growth and mineral nutrition of peach trees [Prunus persica (L.) Batsch (Peach Group) `Golden Queen'] were studied over 3 years (1992-95). Trees were grown in lysimeters of five different volumes (0.025, 0.06, 0.15, 0.4, and 1.0 m3) with either full or deficit (RDI) irrigation. Increasing soil volume increased vegetative growth as measured by trunk cross-sectional area (TCA) (linear and quadratic, P < 0.011) and tree weight (linear, P < 0.001) with the final TCA ranging from 29.0 to 51.0 cm2 and tree weight ranging from 7.2 to 12.1 kg for the smallest to largest volumes. Root density measured at the completion of the experiment decreased with increasing soil volume (linear and quadratic, P < 0.001) with root length density declining from 24.0 to 2.0 cm·cm-3. RDI reduced vegetative growth by up to 70% as measured by weight of summer prunings. Root restriction was effective in controlling vegetative vigor and is a viable alternative for control of vegetative growth. Mineral nutrition did not limit tree growth.

Abstract: The objective of this work was to evaluate the effect of shoot heading and of hand thinning in different development stages of flowers and fruits on the fruit production and quality of 'BRS Kampai' peach (Prunus persica) trees. The experiment was performed during three crop years, under the conditions of the “Depressão Central” region in the state of Rio Grande do Sul, Brazil, and the treatments were: T1, heading of half of the mixed shoot; T2, heading of one third of the mixed shoot; T3, flower thinning in the pink bud stage; T4, thinning at full bloom; T5, thinning of fruit with 5 mm; T6, thinning of fruit with 20 mm; and T7, no thinning or heading (control). Fruit production and quality were evaluated. Plants with no thinning were more productive, but showed high frequency of fruits with a diameter smaller than 60 mm. Shoot heading reduced production per tree and resulted in small-sized fruit. Thinning time did not affect production, and fruit size was greater when thinning was performed at the bloom stage. 'BRS Kampai' peach trees can be thinned starting at bloom, which provides greater fruit size, with no production loss.

Regulated Deficit Irrigation

Regulated deficit irrigation (RDI) involves inducing water stress during specific fruit growth phases by irrigating at less than full evapotranspiration. The objectives of this research were to study the effects of RDI perfomed at stage II of fruit growth and postharvest, on productivity of clingstone peaches, fruit quality as well as photosynthetic rate and midday leaf water potential. The research was conducted in a commercial clingstone peach (Prunus persica L. Batch cv. A-37) orchard in Greece. Trees were irrigated by means of microsprinklers and their frequency was determined using local meteorological station data and the FAO 56 Pennman-Monteith method. Photosynthetic rate was measured by a portable infrared gas analyzer. Midday leaf water potential was measured by the pressure chamber technique. During the years 2005 and 2006, the treatment RDII with irrigation applied at growth stage II of the peach tree did not affect productivity, fresh and dry mass of fruits. RDII reduced preharvest fruit drop in comparison to the control. RDII as well as the combined treatment RDII plus RDIP with irrigation applied at postharvest, at both years reduced shoot length of the vigorous shoots inside the canopy. RDII in comparison to the control increased the soluble solids content of the fruits and the ratio soluble solids/acidity. However it did not affect fruit acidity and fruit firmness. RDII as well as RDII plus RDIP in 2006 increased 'double' fruits and fruits with open cavity in comparison to the control and RDIP. Water savings were considerable and associated with the climatic conditions of each year.
