“…These results may be due to the impact of pruning on increasing the proliferation of roots that leads to an increase in the absorption of nutrients (Saifuddin et al, 2010). Regarding the enhancing effects of P-fertilizer on growth characteristics as reported by the present data, it may be due to the effects of P-fertilizer on improving the levels of plant hormones (IAA, GA 3 and cutokinins) which play pivotal roles in stimulating plant growth (Kahil et al, 2017;Huang et al, 2019). In contrast to the other nutrients necessary for plants, phosphorus is the least mobile and least available for plants under most soil conditions, whether acidic or alkaline because it is suitable for absorption in a certain range of soil pH (Ramaekers et al, 2010).…”

Mill), is one of the substantial industrial crops cultivated for the high-value of its essential oil around the world (Hassan et al., 2018;Attia et al., 2020). Among rose G ETTING the highest flower yield with high-quality volatile oil of Rosa damascena Miller var. trigintipetala Dieck through good agricultural practices is one of the main challenges for oil production. Despite the critical role of pruning and P-fertilizer which strongly improve the flower productivity, their impacts on growth, flower yield, volatile oil and some physiological and biochemical processes are still poorly investigated on damask rose. Thus, in this experiment, two pruning levels i.e. 80 and 100cm from ground level and three rates of P-fertilizer (0, 15 and 30kg P 2 O 5 ha -1 , respectively) were examined. The tallest plants were observed in response to the combined treatment of pruning level at 100 cm and P-fertilizer at 30kg ha -1 . However application of the same P-fertlizer level with pruning at 80 cm resulted in the highest new shoots number/ hill, flower yield components, oil content, relative water content, chlorophyll content, stomatal conductance, total soluble sugars, and N, P and K percentages relative to the other treatments. The flower yield was increased by 23.52% when plants pruned at 80cm and fertilized with P at 30kg ha -1 compared to the pruning at 100cm withought P addition. Decreasing pruning level and increasing P-fertilizer enhanced the protein content while reduced the free amino acids content. Conclusevelly, to obtain higher flower yield and volatile oil productivity, pruning damask rose plants at 80cm and P-fetilizet at 30kg ha -1 is recommended.

“…To improve plant adaptation to a range of stress, grafting scion varieties onto rootstocks is extensively employed for many woody economic species [35,36]. A great deal of research has been conducted on rootstock-induced changes in scion vigor [37][38][39], but there has been a lack of literature that has examined the influence of scion genotypes on biomass allocation and root development in grafted plants, especially under nutrient limitation. A previous study reported variety differences in spatial distribution and monthly dynamics of fine roots for five different cultivars of C. oleifera using the minirhizotron technique [29].…”

Grafting provides a way to improve tolerance to low phosphorus (P) stress for plants, and has been extensively applied in commercial cultivars grafted onto appropriate rootstocks. However, little literature is available concerning the scion-mediated effect on P efficiency in grafted plants. In this study, three different Camellia oleifera Abel. scion cultivars (G8, G83-1, and W2) were grafted onto the same rootstock (W2) under controls (0.5 mM) and low-P (0 mM) availability for eight months. The results showed that the scions significantly affected root-to-shoot weight ratios, the root morphology with a diameter larger than 1 mm, P accumulation, and the P utilization efficiency (PUE) of the root. A higher increase in the root-to-shoot weight ratio under the low-P supply was observed in the G83-1/W2 (26.15%) than in the G8/W2 (0%) and the W2/W2 (5.32%). Root PUE of the scion G8, G83-1, and W2 was improved by up to 113.73%, 45.46%, and 20.97% under the low-P supply. Moreover, G8/W2 exhibited higher shoot P accumulation and the highest root PUE under the low-P supply, indicating a high capability to tolerate P deficiency by maximizing the cost-effectiveness of P remobilization to photosynthetic organs. This suggested the vigorous variety of G8 could be a promising scion to improve grafted C. oleifera tolerance to low-P stress. Our results would have important implications for exploration and identification of a superior scion variety to enhance the ability of resistance concerning P deficiency stress in C. oleifera.

Water stress is the most detrimental stress which has significantly affected the yield particularly in arid climates. It is quite important to provide peanuts with a suitable supplement that can enhance its resistance and yield. Therefore, the current study aims to study the efficacy of cobalt and zinc on peanuts growth, yield, nutrient contents, and water use under full and limited irrigation conditions. For this purpose, a split- split plot experiment was conducted in 2021 and 2022. Three levels of peanuts gross water requirements (GWR) (100, 80 and 60%) were allocated in the main plots. In the sub plots, the plants were treated with cobalt (0 and 7.5 mg l-1). While the sub-sub plots were divided to tested the impacts of chelated zinc as (foliar and soil applications). Under GWR60% we detected marked reductions in yield and it was found that the adoption of separate soil applications of zinc under these conditions or foliar applications of zinc under GWR100&80%, had a significant impact on the most examined traits. However, compared to the control, adopting GWR60% and applying separate cobalt application thereof have significantly led to a lowest decline in iron, copper, yield and water use. Moreover, it was found adoption of foliar zinc applications in a combination with cobalt under GWR60% improved yield. This study recommend adopting GWR60% and treating plants with combined applications of foliar zinc+ soil application of cobalt, which could help plants overcome the negative impacts of water stress and achieve the highest yield and water use.
