Cost-benefit analysis of almond orchard under regulated deficit irrigation (RDI) in SE Spain
Open accessAbstract
A cost-benefit analysis was performed for a mature, commercial almond plantation [Prunus dulcis (Mill.) D.A. Webb] cv. Cartagenera in SE Spain to determine profitability under regulated deficit irrigation (RDI) and an irrigation regimen covering 100% crop evapotranspiration (ETc). The plantation was subjected to two drip irrigation treatments for four years: T1 (control) irrigation providing 100% ETc coverage throughout the growth cycle, and T2 (RDI treatment) an irrigation strategy that provided 100% ETc except during the kernel-filling period, when only 20% ETc coverage was provided. A 28% water saving was achieved with this RDI strategy, while almond production was reduced by only 7%. RDI represented an increase in the efficiency of water use, and cost-benefit analysis showed a 10% mean annual reduction in operating costs compared to the control irrigation regimen. This reduction in costs was basically due to the 28% saving in the cost of water and the corresponding saving in electricity. RDI treatment had a greater short-term than long-term benefit per unit cost. The irrigation costs per kg of almond were 0.76 Euros kg-1 and 0.58 Euros kg-1 under RDI and control conditions respectively. The break-even point was lower under RDI; each kilogram cost 0.05 Euros less to produce than in the control conditions. The results show how RDI, and specifically how this irrigation strategy, may be considered agronomically and economically appropriate in semiarid conditions.

The operational costs found in this study are in the order of magnitude as found in other Spanish almond studies and were validated with a local extension service company.
“Moreover, the operational costs found in this study are in the order of magnitude as found in other Spanish almond studies (García et al., 2004;MAPA, 2018), and were validated with a local extension service company ('Crisara', Chirivel, Spain).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
