چکیده
This investigation was carried out through three successive seasons (2017, 2018, and 2019) on young pomegranate trees of the Wonderful cultivar to study effect four different irrigation treatments (100%, 75%, 50%, 25% crop evapotranspiration—ETc) vegetative growth water–yield relationship. The conducted in Foggia (Apulia region, Southern Italy), an agricultural area characterized by strong wind speeds scarce water resources. results showed effects levels fruit yield characteristics. cumulative trunk diameter, annual shoot growth, number fruits per tree, decreased from full restitution (100% ETc) severe restriction (25% ETc). weight size significantly with volumes applied crop. A linear relationship between consumption (R = 1.00 2018 1.21 2019; n 12) found. use efficiency (WUE) gave no statistical differences among treatments. response factors (Ky: 1.06 0.99 sensitivity pomegranates deficits.

Growth and yield response of potato genotypes to deficit irrigation
In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
متن کاملEffect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
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...
متن کاملAssessment of AquaCrop, WOFOST and CropSyst models for Estimating Sugar Beet Yield under Water Deficit Conditions
Sugar beet is one of the most important agricultural crops and its yield depends on irrigation water. Due to the impossibility of assessing the effect of all water amount strategies on sugar beet yield, it is necessary to use crop models such as WOFOST, AquaCrop and Cropsyst. In order to achieve this goal, a set of data collected from Shahrekord’s Agricultural Research Station were used. Treatm...

Irrigation is an inevitable part of agriculture which determines crop yield and thus food security. In modern era of agriculture, crop yield is determined on the basis of crop production per unit of water-use instead of crop production per land unit area. Deficit irrigation is introduced as a strategy for controlling water resources that leads to water resource preservation. Date palm requires...
