“…Faridvand et al [25] reported that organic fertilizers improved the growth of fennel due to their effect on the availability of most of the micro and macronutrients compared to chemical fertilizers. Eisa [61] found that organic additives (farmyard and chicken manure) and mineral NPK (50 and 100% of RD) resulted in the highest N, P, and K content in fennel plants. Previous studies proved that the accumulation of N, P, and K in plants in response to chemical, organic, and bio-fertilizations as reported in caraway [47], chamomile [62], collard [63], moringa [32], kale [64], and coriander [65].…”

Fennel fruits (Foeniculum vulgare Mill.) represent one of the plant-based natural spices. This study aims to improve the fruit yield and essential oil (EO) quality by reducing the undesirable component, estragole, under different fertilizer treatments. The fertilizers included chemical nitrogen, phosphorus, and potassium (NPK), and also the organic additive, rabbit manure (RM). For bio-fertilization, plants were inoculated with a mixture of N-fixing bacteria, and P- and K-solubilizing bacteria with/without vesicular-arbuscular mycorrhizal fungi. The results showed that fruit and EO yield parameters, total phenolic content (TPC), total flavonoid content (TFC), and DPPH scavenging activity of fruit extracts were enhanced by fertilizer treatments in both growing seasons. NPK at 150% of the recommended dose (NPK150) and RM at 60 m3/fed (RM60) recorded the highest values of plant height, umbel number/plant, 100-fruit weight, fruit yield, chlorophyll, carbohydrates, N and P content, EO content, and yield. TPC and TFC were enhanced by using biological fertilizers. DPPH scavenging activity was higher in organically and biologically fertilized fennel. The GC-MS analyses of EO revealed higher contents of the desirable trans-anethole in the organically and chemically fertilized fennel. However, the highest proportion of estragole, the undesirable compound, was recorded for NPK150 and unfertilized plants. On the contrary, increases in the EO content and yield of fennel fruits were achieved by RM along with a reduction in estragole, enhancement in trans-anethole, and increments in other favorable compounds such as fenchone and limonene. In addition, the inhibition of estragole formation was recorded with bio-fertilizers, which also increased the trans-anethole content. Furthermore, the trans-anethole/estragole ratio was significantly higher with the application of organic and bio-fertilization. Hence, organic and bio-fertilizer resources can produce high-quality fennel fruit and EO. The reduction in the use of chemical fertilizers can help to reduce environmental pollution.

“…Recently, Shehata et al (2011) and Eisa (2016) found that the percentages of N, P and K in leaves of sweet fennel and celeriac plant were increased significantly with foliar application of seaweed extract. The highest respect values of macronutrients (N, P and K) might be attributed to organic and mineral elements constituents of seaweed extract.…”

A field experiment was carried out for two successive winter and summer seasons (2016)(2017) at Ismailia Agric. Res. Station in Ismailia Governorate, Egypt using wheat (Triticum sativa cv Giza 168) and peanut (Arachi shypogaea cv Giaz 5) crops to study the effect of organic soil conditioners individually or mixed with synthetic soil conditioners on physical and chemical properties of sandy soil, nutritional status and plant productivity. The experiment was arranged in split plots design with three replicates. Five forms of organic soil conditioners were applied as main plot consists of control (NPK), yeast sludge (YS) at rate of 2 kgfed -1 , commercial humic acids (HA at rate of 1 kgfed -1) , seaweed extract (SWE) at rate of 100 g fed -1 and filter mud (FM) at rate of 5 kgfed -1 ). While the sub main plot using synthetic soil conditioners as zero addition, carboxymethyl cellulose (CMC) at rate 2% and polyvinyl alcohol (PVA) at rate 0.2 %. Results cleared that the interference usage of organic soil conditioners in combination with synthetic soil conditioners had positively affect hydro-physical properties of the soil, i.e., decreasing soil bulk density, increasing total porosity along with dry stable aggregate, as well as, the superior treatment is SWE + CMC. In general, there is no valuable difference between SWE and organic residues, whereas, YS and FM have the same trend over to control. In addition, organic matter (OM) and available macronutrients N, P and K content in soil were increased significantly with all treatments applied compared to control, the maximum increases were observed with SWE application mixed with CMC. An opposite trend was obtained with both pH and EC values which generally decreased at all applied treatments especially with (SWE+ CMC) Therefore, the application of seaweed as organic soil conditioner individually or mixed with CMC or PVA which increased significantly both wheat and peanut biological yields, straw grain and/or seed, along with total N, P and K content as compared to either control or other organic treatments application. Moreover, obtained results showed highly significant correlation ( p< 0.05) between grain and/or yield and soil EC, OM, P and N in spite of none significant correlation with pH and K. Finally, it can be concluded that organic soil conditioner especially seaweed and sugar cane byproduct was enhanced and became more effective when applied with polymers especially CMC.

“…The results showed in figure (6) and table (5) that the gene SIActin has an effective response to the effect of organic and phosphate fertilizer , whether alone or in combination, as the treatment gave 160 kg. D -1 of phosphate fertilizer, and the genotype Dollap had the highest genetic expression, which reached ( 9.849155 ) , followed by the treatment of 8 T. D -1 and genotype Hannan, which amounted to ( 9.189587 ) , while the comparison treatment and Local genotype gave the lowest gene expression and was( 0.143587 ).…”

“…This is due to its spread in folk medicine and its uses in various pharmaceutical preparations, as it contains an important essential oil at a rate of (3-6%) and includes a number of effective and active compounds, including (Anethole), (Limonene), (α-pinene), (Estragol) and ( Fenchone), which has the distinctive aroma of a fennel, and these compounds are used as a diuretic, carminative, and sedative [2][3][4] . fennel is also used as a treatment for upper respiratory tract infections due to its sedative effects on bronchitis and cough [5,6]. He pointed out [7] that the leaves of the fennel are used in the treatment of diarrhea and sexual weakness.…”

In the winter of 2021-2022, researchers on the hamlet of Banat Al-Hassan, southeast of Samarra (Iraq), conducted a field experiment in gypsum soil on one of the private farms there. Both zero and eight tons of organic fertilizer were used in the experiment. 0 and 160 kg of phosphate fertilizer D−1 and D−2. D−1 without competition from the other five sweet fennel genotypes and two fertilizer types (Local, Amigo, Dollap, Azuricum, Hannan). According to the findings, the SIPR1 gene in the 8-ton had the highest level of expression. The highest dose of D-1 for organic fertilizer treatment for the Azuricum genotype was 9.986644 mg, followed by 160 kg of the SIActin gene. Dollap genotype required 9.849155 g of D−1 phosphate fertilizer.
