One such practice is use of agro-waste biochar in agricultural, environmental, and climatic operations. The viability of using a biochar-based nanocomposite as a support fertilizer for the gradual release of nitrogen, potassium, and phosphorus in various media is examined in this study. The banana peel biochar (BPBC) and its nanocomposite (BNF) were prepared using a simple yet comprehensive chemical process. Synthesized materials were evaluated using FT-IR and SEM/EDX. Physical attributes as well as fertilizer basic characteristics were determined and prepared nanocomposite demonstrated noticeably better water absorbance ratio (68%), equilibrium water content (78.97%), and swelling ratio (3.64 g g⁻¹) than biochar, which is advantageous for preserving soil water levels. The salt index values (0.087mmhos/cc) of the created nanocomposite performed better when compared to the conventional fertilizers due to their safer application. Long-term availability of all doped minerals to the plants, during experimental cycle, was revealed by slow-release nutrient studies in water and soil, which is ideal for promoting germination and growth. The findings of this research revealed that prepared BNF showed improved germination parameters i.e., time for 50% germination (3.4, 3.3, 4.4 days), germination index (3.1, 3.5, 2.4), final germination percentage (91.7, 100, 83.3%), mean germination time (4.0, 3.9, 4.9 days), for cucumber, broccoli and okra, respectively. In addition to that the prepared BNF facilitated enhanced shoot and root length in all the three vegetables as compared to conventional fertilizers. The dose optimization studies depicted that best results of germination as well as plant growth parameters are facilitated by BNF (37.5 kg/ha) owing to enhancement in soil quality by supplying additional organic matter in addition to provision of nutrients on slow-release.</p></div>","PeriodicalId":17560,"journal":{"name":"Journal of the Saudi Society of Agricultural Sciences","volume":"22 8","pages":"Pages 535-545"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1658077X23000681/pdfft?md5=5c176db977a2f2a8e95daec0663341c0&pid=1-s2.0-S1658077X23000681-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47338193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Colombia, the tendency has been to grow short-cycle horticultural species, such as butternut squash (Cucurbita moschata Duchesne), that present efficient water use response. To study the physiological response of three butternut squash cultivars (UNAPAL Abanico-75, UNAPAL Bolo Verde, UNAPAL Dorado) to soil moisture regime (Kc), four irrigation water depths in two consecutive trials (0.4; 0.6; 0.8 y 1.0 trial I y 0.6; 0.8; 1.0 y 1.2 trial II) were applied in a split-plot design with 8 replicates, totaling 96 plants, where the main plot was the irrigation treatment and subplots, the cultivars. Physiognomic variables (biomass, leaf area, number of stomata, root length) showed significant biological performance (P<0.05) when the maximum soil moisture regime (Kc=1.2) was applied. In contrast, plants presented significant discrepancies in dimension and appearance (P<0.05) in water deficit conditions (Kc=0.4), with a significant decrease (P<0.05) in leaf blade macromolecular composition (soluble protein, soluble carbohydrates, chlorophylls a and b, carotenes). Water deficit also triggered hydrogen peroxide (H2O2) production, to which plants responded by producing enzymes to protect photosynthesis reactions. Malondialdehyde, proline, superoxide dismutase, catalase, peroxidases, and ascorbate peroxidase therefore increased significantly (P<0.05), all of which help restrict H2O2 while protecting plant cells from lethal lipid peroxidation caused by free radicals, the latter being significant (P<0.05) in the tolerance response of cultivars Abanico-75 and Dorado to water deficit.

Pathogen-antagonist interactions were studied in dual culture, and the morphological alterations of <em>M. phaseolina</em> mycelia in the interaction zone were examined by light microscopy. <em>Trichoderma</em> strains were applied to soya bean seeds by a seed coating technique. Their bioprotective effects were assessed by <em>in vitro</em> and <em>in vivo</em> assays to evaluate radicle length, the germination percentage and the presence of typical charcoal rot symptoms in seedlings. Two <em>Trichoderma</em> strains were selected and they were molecularly identified as <em>T. harzianum</em> species complex<em>.</em> Their antagonistic ability against <em>M. phaseolina</em> was evaluated under different water availability conditions. The mechanisms used by these two endophytic strains against the pathogen were evaluated by cryo-scanning electron microscopy. The results showed that all eight <em>Trichoderma</em> strains successfully performed biocontrol activity against <em>M. phaseolina</em> by reducing colony growth and causing morphological alterations in the mycelia of <em>M. phaseolina</em>. All endophytes improved seed germination and radicle length, and reduced typical symptoms and disease progression on seedlings. Water availability in the medium impacted on fungal growth.
