Effect of Decreasing Water Irrigation Quantity on Growth and productivity of Flame Seedless Grapevines in Clay Soils Conditions

Abstract

The present investigation was carried out during three successive seasons (2015, 2016 and 2017)to determine water requirement on growth, yield and fruit quality features of Flame seedless grapevines. In Aga, Dahlia Governorate, Egypt, the chosen vines were seven years old, planted in a clay soil, spaced 2.5×2 meters apart and irrigated by flood system, spur pruned, trained to the quadrilateral cordon and trellised by the pergola system. The vines were pruned during the second week of January with bud load (56 buds/vine).The work in the first year was considered as a preliminary trial and then the experiment proceeded with the same manner during the second and third seasons, respectively. Four levels of irrigation water as follows: irrigation with5000m 3 /Fadden (control), 4500m 3 /Fadden, 4000m 3 /Fadden and 3500m 3 /Fadden. Obtained results revealed that irrigation of Flame seedless grapevines with 4000m 3 /Fadden recorded the highest water use efficiency which it reflected in getting vegetative growth better, increasing yield/vine and improving berry quality attributes of Flame seedless grapevines in both seasons. From the obtained results, it can be recommended that Flame seedless grapevines irrigated with 4000m 3 /Fadden had the best results which it gained a good yield with high fruit quality attributes.

Effect of Irrigation Systems, Rates and Polymer on Water Use Efficiency, Yield and Fruit Quality of Grape Under Desert Conditions

“…These results may be due to that subsurface drip irrigation allows uniform soil moisture, minimize the evaporative loss and delivery water directly to the plant root zone which increases use efficiency (Kramer and Boyer 1995). This result agreement with Gaser et al (2018) who showed that water use efficiency (WUE)was significantly affected by different levels of irrigation in 2016 and 2017 seasons of this study. It was found that vines irrigated with 4000m3 /Fadden had significant values of this parameter followed by 4500m3 /fadden, while 5000m3 /fadden ranked the third position.…”

Effect of Superabsorbent Polymer Application on Soil Hydraulic Properties, Growth, Yield, and Water Use Efficiency of ‘Early Sweet’ Grapevine (Vitis vinefera) under Different Irrigation Levels

“…The highest percentage of fruitful buds with SAP application may be due to the increasing water-holding capacity of the soil around the roots. These results are in somewhat agreement with those found by EL Gendy (2012) and Gaser et al (2018), who reported that water stress was effective in inducing early bud break compared to continuously well-watered vines.…”

“…This is confirmed by Branch et al (2009), who showed that the application of SAP increases vegetative growth by increasing the soil's capacity to store water and nutrients. This result agreed with Gaser et al (2018), who reported that water stress decreased vegetative growth traits in grapevine. Additionally, the findings of our study are consistent with those of Pattanaaik et al (2015), who discovered that soil application of SAP at a concentration of 100 g/tree greatly improved the vegetative growth of Khasi mandarin compared to the control.…”

“…Lower water use and increased WUE by the crop are evidence of this, which is a key goal of deficit irrigation systems in vineyards (de Souza et al, 2005). This result agreed with Wei et al (2017) and Gaser et al (2018) who showed that water use efficiency (WUE) was significantly affected by slight deficit irrigation. Water use efficiency (WUE) can be increased by using SAP under slight deficit irrigation (Rabeh et al, 2022).…”

Evaluation and description of three grape cultivars suitable for export under Egyptian conditions

“…These results are consistent with those obtained by El-Morsy et al (2017), who studied the black cultivar Arra 24 and the white cultivar Arra 30, noting that these cultivars exhibited thick internodes. According to Gaser et al (2023), cultivars of starlight and sugrafourteen showed the same tendency and numerous researchers working with various cultivars Tarbia, 2017 andEl-Sayed andFayed, 2023).…”
