Abstract
The increasing demand for high quality fertilizer, which is being driven by human nutrition demand and agricultural soil protection, necessitates sustainable alternatives to be used as vegetable production. Thus, utilizing biochar (BC), bacterial fertilizer and their combination with organic fertilizer (OF) could be a sustainable approach. In our research work, OF, BC, liquid bacterial fertilizer (LB), and solid bacterial fertilizer (SB) were used to investigate different fertilizer combinations. Greenhouse field experiment was conducted to compare different fertilizer application and their effects on cabbage biomass, cabbage characteristics and soil physical and chemical properties. The results showed that combined application OF, BC, and LB promoted cabbage growth and resulted in the highest yield of 16.6 kg/m2. The vitamin C content was highest at 48.4 mg/kg with the combined application OF, BC, and SB treatment. The combined application OF, BC, and SB achieved the best overall comprehensive evaluation for cabbage biomass weight, vitamin C content, and total sugar content. The combined application OF and a bacterial fertilizer improved soil properties, while the addition of BC reduced the soil nutrient content. Gas chromatography-ion mobility spectrometry (GC-IMS) analysis showed that volatile organic compounds from cabbages were mainly esters, alcohols, acids, acetates, aldehydes, and ketones. These results provide a comprehensive understanding of different fertilizer applications and their effects on cabbage quality and rhizosphere soil.
期刊介绍:
The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues.
Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and:
Lack of water (drought) and excess (flooding),
Salinity stress,
Elevated temperature and/or low temperature (chilling and freezing),
Hypoxia and/or anoxia,
Mineral nutrient excess and/or deficiency,
Heavy metals and/or metalloids,
Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection,
Viral, phytoplasma, bacterial and fungal plant-pathogen interactions.
The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
