Indoor medicinal cannabis cultivation systems enable year-round and better control of growing factors, however, such are energy resource intensive. Nutrient deprivation during flowering can trigger nutrient translocation modulate the production cannabinoids, which might increase agronomic use efficiency, thus, a more sustainable fertilizers. This experiment compares two fertilizer types (mineral organic) applied in three dilutions (80, 160 240 mg N L −1 ) to evaluate effect on biomass, Cannabidiol (CBD) yield efficiency N, P K. is first study showing potential reduce input while maintaining CBD cannabis. Under stress, inflorescence was significantly lower at final harvest, this compensated by higher concentration, resulting 95% using one-third less fertilizer. The P, K nutrient-deprived plants achieved larger mobilization nutrients increasing utilization acquired nutrients. – for increased 34% organic fertilizers 72% mineral comparing dilution with (160) highest concentration (240). Differences between occurred only harvest indicating limitations uptake due forms Our results showed acquisition fertilizer, proposing necessity improve either timing bio-availability or soil amendments.

Nitrogen Sources Reprogram Carbon and Nitrogen Metabolism to Promote Andrographolide Biosynthesis in Andrographis paniculata (Burm.f.) Nees Seedlings

Carbon (C) and nitrogen (N) metabolisms participate in N source-regulated secondary metabolism medicinal plants, but the specific mechanisms involved remain to be investigated. By using nitrate (NN), ammonium (AN), urea (UN), glycine (GN), respectively, as sole sources, we found that sources remarkably affected contents of diterpenoid lactone components along with C reprograming Andrographis paniculata, compared NN, other three raised levels 14-deoxyandrographolide, andrographolide, dehydroandrographolide (except UN), neoandrographolide AN) a prominent accumulation farnesyl pyrophosphate (FPP). These also photosynthetic rate fructose and/or sucrose reduced activities phosphofructokinase (PFK), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), phosphoenolpyruvate carboxylase (PEPC) pyruvate (PDH). Conversely, carboxykinase (PEPCK) malate enzyme (ME) were upregulated. Simultaneously, citrate, cis-aconitate isocitrate declined, assimilation was inhibited. results indicated AN, UN GN metabolic flow carbohydrates from glycolysis into TCA cycle downstream assimilation. Furthermore, they enhanced arginine GABA metabolism, which increased replenishment cycle, ethylene salicylic acid (SA) levels. Thus, proposed reprogrammed attenuating competition for C, promoting synthesis andrographolide through plant hormone signaling. To obtain higher production A. AN fertilizer is recommended its management.
