Biochar was generally used to reduce the macronutrient releases and to mitigate NO gas emissions in cropland. This experiment evaluated the trend of major plant nutrient releases using the modified Hyperbola model and the greenhouse gas emissions by incorporating different poultry manure compost biochar with organic resources. The treatments consisted of the control as the organic fertilizer materials, the incorporated poultry manure compost biochar with organic fertilizer materials (PMCBF), and the incorporated plasma-activated poultry manure compost biochar with organic fertilizer materials (PAMBF) under redox conditions.

This study investigated the effect of plasma treatment on reused water and evaluated the interactions of the plasma-treated water (PTW) with plants or microbes to determine the optimal PTW for reuse. The repeated treatment gradually accumulated nitrate (NO) in the PTW and lowered its pH; afterward, it led to the sprouted soybeans accumulating other inorganic ions in the PTW. The biomass of soybean sprouts was enhanced by the accumulated NO but decreased due to the pH effect.

Cold plasma treatment has been studied to enhance the germination, growth, and bioactive phytochemical production in crops. Here, we aimed to investigate the effects of cold plasma treatment on the growth, bioactive metabolite production, and protein expression related to the physiological and osteogenic activities of oat sprouts. Oat seeds were soaked for 12 h, and then exposed to plasma for 6 min/day for 3 days after sowing.

Ginseng (Panax ginseng Meyer) sprouts are grown to whole plants in 20 to 25 days in a soil-less cultivation system and then used as a medicinal vegetable. As a nitrogen (N) source, plasma-treated water (PTW) has been used to enhance the seed germination and seedling growth of many crops but has not been investigated for its effects on ginseng sprouts. This study established an in-situ system for N-containing water production using plasma technology and evaluated the effects of the PTW on ginseng growth and its bioactive phytochemicals compared with those of an untreated control.

Crops during their early growth stages are vulnerable to a wide range of environmental stressors; thus, earlier seed invigoration and seedling establishment are essential in crop production. As an alternative to synthetic chemical treatments, plasma technology could be one of the emerging technologies to enhance seed germination and seedling vigor by managing environmental stressors. Recent studies have shown its beneficial effects in various stress conditions, suggesting that plasma treatment can be used for early crop stress management.

Article Synopsis
  • This study investigates gene flow from genetically modified (GM) herbicide-resistant Brassica napus to its wild relatives through wind and bee pollination, which raises ecological concerns in agricultural settings.* -
  • Results show that the maximum gene flow to male sterile (MS) B. napus and B. juncea decreased significantly with distance from HR B. napus, with positive percentages only within close proximity; for MS R. sativus, there was no observed gene flow.* -
  • The findings indicate that small donor plots favor insect pollination over wind, highlighting the need for better management of gene flow to mitigate environmental risks.*

Background And Objectives: The volume of the air cavities in the paranasal sinuses is not only the simplest, but also the most important index for paranasal sinus evaluation. However, few volumetric studies have been performed in all age groups. The purpose of the current study was to outline the normal development of paranasal sinuses in all age groups, and to determine normal adult volumetric values by means of computed tomographic (CT) scan of paranasal sinus using volumetric procedures.
