“…The specific angle of contact considers the indicator which determines the ability of plant to absorb solutions through their shoot. So, even there is an increase in angle value, that leads to more disharmonies between them and less absorption of the solution which means less benefiting (Macedo et al, 2021). This is due to the abundance and density of alkaloid substances that cover the cauliflower leaves, which prevent or reduce the absorption of many of the liquids that are sprayed on their leaves surfaces.…”

The experiment was conducted at the research station of the Department of Horticulture and Landscape - College of Agriculture - Tikrit University for the 2019-2020 season, to study the effect of spraying organic fertilizer (seaweed extract) and growth regulator (cytokinin) on the growth and yield of the cauliflower plant. The experiment included two factors: spraying seaweed extract in three levels, (S0) 0 ml l-1 as a control, (S1) 3.3 ml l-1, (S2) 6.6 ml l-1. The second factor was spraying cytokinin in three levels: (G0) 0 mg l-1 as a control, (G1) 10 mg l-1, (G2) 40 mg l-1. The experiment was carried out according to the Randomized Complete Block Design R.C.B.D with three replications and the averages were compared according to Duncan's multiple range tests at a probability level of 5%.The results showed that spraying seaweed extract (S2) increased the percentage of phosphorus, potassium and boron significantly compared with all other treatments. Meanwhile, the application of cytokinin did not affect significantly on all the studied characteristics. The interaction traetments caused significant effect in fresh weight of leaf, phosphorus%, and potassium% with S0G0, S2G2, and S2G0 respectively compared with S2G0, S0G0, and S0G2 treatments which had the lowest values for previous characteristics respectively.

“…Nutrient solution varies according to composition and plant nutritional status, with the lowest concentrations used with the highest salt index fertilizers to avoid leaf burning and not severely de cient trees (Hippler et al 2018a, b;Sawan et al 2001). In addition to these soluble salts, chelated fertilizers, such as ethylenediaminetetraacetic acid (EDTA) or sparingly soluble sources, are available for foliar applications (Bell and Dell 2008;Macedo et al 2021). However, chelated micronutrients are likely not e ciently absorbed by citrus leaves (Boaretto et al 2002;Sartori et al 2008;Zhang et al 2014).…”

Background and AimsCitrus trees are severely affected by zinc (Zn) de ciency, which impairs plant growth and fruit yield. Zn fertilization is usually recommended in eld orchards, and application strategies toward nutrient use e ciency are key for successful crop management. MethodsField studies were carried out with sweet orange trees for four growing seasons, testing Zn (nitrate, sulfate or EDTA) applied either via fertigation or foliar spray compared to a control without Zn. ResultsThe Zn concentrations in the soil increased with nutrient supply by both application methods. Zn-EDTA via fertigation increased soil nutrient availability compared to the control. Likewise, Zn-nitrate via foliar application also increased soil Zn levels. Regarding the plant, Zn-EDTA via fertigation increased leaf nutrient levels only after the third year of fertilization, whereas Zn-nitrate via foliar spray increased leaf levels in the short term, up to 120 mg kg − 1 . To a lesser extent, Zn-EDTA or sulfate also increased leaf Zn compared to the control. Accumulated fruit yield was ~ 20% higher in trees with Zn-EDTA via fertigation and ~ 20% higher in trees with Zn-nitrate or sulfate via foliar application compared to the control, with these latter exerting greater responses. Trees supplied with Zn exhibited lower H 2 O 2 and higher CAT activity compared to the control, which correlated with a fruit yield increase. ConclusionIn conclusion, Zn-EDTA via fertigation or nitrate or sulfate via foliar application improved the horticultural performance of trees, supporting the establishment of best nutrient management practices in fruit production.

“…However, the capacity of leaves in absorbing, metabolizing and translocating such particles is still a matter of controversy. Macedo et al (2021) found Zn and B uptake from concentrated suspension in coffee plants grown for 240 days after foliar fertilization under controlled conditions. In opposite, Migliavacca (2021), in a short-term study, found that poorly soluble sources of Mn were not able to revert deficiency symptoms by soybean whereas the soluble sources reverted such symptoms.…”

Uptake of zinc by soybean leaves using sources with different solubilities

Uptake of zinc by soybean leaves using sources with different solubilitiesZinc is an essential micronutrient for soybeans, and its absorption in plants is affected by the solubility of zinc sources in the soil. In this study, we investigated the zinc uptake by soybean leaves using foliar application of different zinc sources with varying solubilities. We used three different zinc sources: zinc oxide, zinc sulfate, and zinc EDTA, each with different solubilities. The experiments were conducted in four soybean cultivation areas: Santa Carmem/MT, Itaara/RS, Itai/SP, and Piracicaba/SP. The applied dose of zinc was 400 mg per hectare, with the objective of evaluating whether soybean performance when fertilized with less soluble sources could match that of soluble sources. This dose was split into two applications, at growth stages V4 and V8, and leaf samples were collected at stages V6, R2, and R4. Trifoliate leaves were also collected for the analysis of antioxidative enzymes, assessment of micronutrient content in the grains and leaves, as well as productivity and 1000-grain weight evaluations. However, in this study, it was not possible to establish a clear relationship between different soybean yields when comparing low-solubility sources with highly soluble ones.
