“…Similarly, Zhang et al [2004] reported that N fertilizer use is often double than recommended in intensive vegetable farming. Unrestricted N application is wasteful and can extend the growing period and post-pone crop maturity [Easmin et al 2009], increasing economic costs and negatively affecting human health [Elgala et al 2022]. Therefore, the reasonable use of nitrogen fertilizers should be of primary importance for protecting the environment from pollution and farm profitability [Saudy et al 2020].…”

A three-year field trial was conducted to determine the effects of mulching with black polyethylene film and fertilizing with organic and mineral fertilizers in mid-early cabbage production. The two-factor trial was set up as a split-plot design. The main plots included unmulched and mulched treatments. The sub-plots consisted of unfertilized control and five fertilized treatments. In the first and third trial years, total cabbage yield, total head yield, and average head weight were significantly higher on black polyethylene film plots than on unmulched plots. However, in the second year, the mean air temperature during cabbage growing exceeded the long-term average, and values of the examined parameters did not differ significantly between the mulched and unmulched treatments. In all three years, amounts of removed nutrients were significantly higher in treatment with composted pig manure + mineral fertilizer. Mulching significantly increased fertilizer use efficiency in the first and third years, while the second year saw better results on unmulched plots.

“…However, it lacks essential components such as glucose, organic acids, as well as calcium and magnesium ions that are necessary for plant growth. The application of water-soluble fertilizer helps to compensate for these deficiencies by providing the required nutrients to support plant growth [ 59 , 60 ]. As a result, combination of the modifier and water-soluble fertilizer application is more conducive to improvement of saline-alkali soil and crop growth on saline-alkali soil.…”

Saline-alkali soil significantly impairs crop growth. This research employs the impacts of the modifier and water-soluble fertilizer, as well as their interaction, on the root systems of alfalfa and leymus chinensis in saline-alkali soil. The results exhibit that the hydrochar source modifier effectively enhances the root growth of both forage species. There are certain improvements in the root growth indicators of both crops at a dosage of 20 g/kg. Root enzyme activity and rhizosphere soil enzyme activity are enhanced in alfalfa, showing significant improvements in the first planting compared to the second planting. The application of water-soluble fertilizers also promotes root growth and root dehydrogenase activity. The root dehydrogenase activity of alfalfa and leymus chinensis are enhanced 62.18% and 10.15% in first planting than that of blank, respectively. Additionally, the two-factor variance analysis revealed a correlation between rhizosphere soil enzyme activity and changes in root traits. Higher rhizosphere soil enzyme activity is observed in conjunction with better root growth. The combined application of a modifier and water-soluble fertilizer has demonstrated a significant interaction effect on various aspects of the first planting of alfalfa and leymus chinensis. Moreover, the combined application of the modifier and water-soluble fertilizer has yielded superior results when compared to the individual application of either the modifier or the water-soluble fertilizer alone. This combined approach has proven effective in improving saline-alkali soil conditions and promoting crop growth in such challenging environments.

“…Also foliar spray may be more efficient than the mixing application due to the microorganism degradation of allelochemicals after they have been liberated into the soil; allelochemicals have a wide range half-lives, from a few hours to a few months (Wang et al 2007;Bertin et al 2009). Furthermore, since plant extracts involve several micronutrients, they have an additive beneficial effect on plant growth and development (Elgala et al 2022).…”

Evaluation of Ficus nitida Allelopathic Potential and the Most Efficient Application Method for Controlling Weeds Associated with Sunflower Plant

Allelopathy is a phenomenon by which plants positively or negatively affect neighboring plants by releasing allelopathic compounds. These allelochemicals are secondary metabolites found in different concentrations in shoots, roots, leaves, flowers, and even pollen grains. Allelochemicals have potential as natural bioherbicides for controlling weeds when applied in the form of extracts or through intercropping, cover cropping, and mulching. The present study was conducted to investigate the allelopathic potential of Ficus nitida leaves against Echinochloa crus-galli L. and Corchorus olitorius L weeds associated with sunflower plant via two application methods (mixing of F. nitida leaf powder with soil and foliar spray of F. nitida leaf powder alcoholic extract). Two pot experiments were carried out for the two summer seasons of 2020 and 2021 in the greenhouse of the National Research Centre (NRC), Dokki, Giza, Egypt. Nine treatments were applied in a completely randomized block design. Three treatments were applied before sowing, namely F. nitida leaf powder was mixed with the soil at rates of 15, 30, and 45 g/pot. The other three treatments of alcoholic leaf powder extract of F. nitida were sprayed twice on both plants and weeds at 10, 20, and 30% (w/v) concentrations. Additionally, three check treatments—healthy (sunflower only), unweeded, and both weeds only—were applied for comparison. The recorded results showed that F. nitida had an allelopathic bioherbicidal effect on both weeds. By increasing the concentration of F. nitida extract, the bioherbicidal potential increased. Moreover, the recorded results showed that foliar spray of alcoholic extract at 30% concentration was the superior application method for controlling weeds. Mixing of F. nitida leaf powder at 45 g/pot ranked second after this superior treatment. A noticeable result is that these two superior treatments improved sunflower growth parameters and yield traits. Quantitative estimation of phenolic compounds and flavonoids demonstrated that the concentration of these allelochemicals is higher in alcoholic extract than in water extract. Moreover, phenolic acid concentrations as detected by high-performance liquid chromatography fractionation are higher in alcoholic extract than in water extract.
