Chickpeas (Cicer arietinum L.) are a valuable legume crop due to their nutritional value. To maintain chickpea productivity and avoid the adverse effects of climate change on soil and plant processes, it is crucial to address demand. Achieving this necessitates implementing sustainable agricultural practices incorporating the use of biostimulants, adaptable crops for arid conditions, as well as pest and disease-resistant crops that are sustainable over time. Three varieties of chickpeas were analysed to determine the effect of two different biostimulant application methods on both germination and vegetative growth. Possible effects due to location were also examined by conducting tests at two different sites. Significant variations in biostimulant response were evident only during the germination period, but not during the vegetative development stage, where the observed statistical differences were influenced more by the location or variety of chickpeas employed. Furthermore, this study examined the effect of biostimulants on nutrient cycling within the soil–plant microbiota system. Nitrogen-fixing bacteria (NFB) are present in the soil of chickpea crops at an order of magnitude of 10⁷ CFU/g DS. Additionally, an average concentration of 10⁶ CFU/g DS of phosphorus-mobilising bacteria was observed. Applying biostimulants (BioE) to seeds resulted in a successful germination percentage (GP) for both Amelia (AM) and IMIDRA 10 (IM) varieties.

Camelina sativa (L.) Crantz, a native European oilseed crop of the Brassicaceae family, is notable for its short life cycle, making it well-suited for crop rotation and diversification. Its seeds contain a high content of oil (36–47%) that is rich in polyunsaturated fatty acids (PUFAs) such as alpha-linolenic acid (ALA, C18:3, Ω-3) and linoleic acid (LA, C18:2, Ω-6). This oil has diverse industrial applications, including low-emission biofuels, animal feed, pharmaceuticals, biolubricants, bioplastics, and cosmetics. We analyzed the expression of seven key enzymes involved in fatty acid biosynthesis across nine C. sativa accessions at three stages of silique development using highly efficient qRT-PCR assays designed for the target genes and a normalizing control. Our detailed expression analysis revealed significant variation across varieties, with only the gene FAB2c exhibiting genotype-independent expression, indicating a constitutive and essential role in monounsaturated fatty acid (MUFA) biosynthesis. Other genes showed significant interactions between the variety and developmental stage, highlighting the combined influences of genetic background and silique maturation on gene regulation. V18 emerges as particularly promising, exhibiting elevated expression of genes linked to PUFA and VLCFA biosynthesis—traits of significance for food, biofuel, and industrial applications. These findings, together with the developed qRT-PCR assays, provide valuable tools for selecting Camelina varieties with optimized genetic profiles, highlighting the potential of harnessing natural transcriptional diversity for crop improvement.
