چکیده
Irrigated agriculture in semi-arid regions is expected to increase the future, which puts greater demands on scarce water resources. Sustainable irrigation strategies will support agricultural resilience climatic change. The response of “Sweetheart”/Mazzard sweet cherry trees ( Prunus avium L.) postharvest deficit (PDI), as a conservation method, was studied over three seasons (2019–2022) Okanagan Valley British Columbia, at five commercial orchards. following treatments were applied; i) control full irrigation, irrigated according conventional growers’ practice each orchard, ii) PDI-30: 27%–33% reduction volume, after harvest (67%–73% control), and iii) PDI-50: 47%–52% (48–53% control). Spring phenology (the timing flower bud development, from side green bloom), moisture content cold hardiness, fruit yield quality (before storage shelf-life conditions) assessed determine if PDI altered development subsequent growing season. Neither PDI-30 nor PDI-50 caused changes phenology, hardiness or relative control. also had no effect conditions. These results suggest could be used reduce use regions, like Valley, without affecting production quality.

Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...

The effects of regulated deficit irrigation (RDI) were studied on 9 year-old apricot-trees (Prunus armeniaca L. cv. ‘Búlida’) grafted on ‘Real Fino’ rootstock. Two irrigation treatments were established. The first, a control treatment, was irrigated to fully satisfy the crop water requirements (100% ETc) and the second, a RDI treatment, was subject to water shortage during the non-critical peri...
