Published: Sept. 22, 2023

For a long time, marine macroalgae (seaweeds) have been used to produce commercial biostimulants in order ensure both productivity and quality of agricultural crops under abiotic stress. With similar biological properties, microalgae slowly attracted the scientific community biostimulant industry, particular because their ability be cultivated on non-arable lands with high biomass all year long. Moreover, recent strategies culturing these photosynthetic microorganisms using wastewater CO2 opens possibility large quantity at moderate costs while integrating local circular economy approaches. The paper aims provide state art review development cyanobacteria based biostimulants, focusing different cultivation, extraction application techniques available literature. Emphasis will placed cultivation liquid gaseous effluents as well emerging green-extraction approaches, taking consideration actual European regulatory framework.

Gibberellic acid (GA3) may help to synchronize coffee flowering, whilst ethylene (in the form of Ethephon) assist in advancing berry maturation even when applied pre-flowering stage phenophase. Functional–structural plant modeling (FSPM) can be used understand whole-plant responses, such as plant-scale photosynthesis. FSPM has never been investigate response plants external growth regulator (PGR) applications. We hypothesized that treatment with PGRs at beginning (BM) during phenophase could (1) influence leaf area and photosynthesis end BM (2) uniformity seven-year-old plants. Additionally, we assumed (3) distribution berries over vertical profile related beans’ chemical quality, irrigated would have delayed maturation, but a higher yield than non-irrigated (NI) To test these hypotheses, short sustainable period irrigation was six weeks before harvest. Irrigated were treated GA3 or Ethephon. A combination field measurements (leaf gas exchanges, collection bean analyses relation strata) computer used.

AbstractCrop production plays a critical role in global food security, with key commodities such as corn, wheat, soybean, and rice ranking among the most widely cultivated crops. These major crops are predominantly grown within extensive cropping systems. However, these systems threatened by fungal diseases, which may cause substantial yield reductions. The adopted strategy to manage pathogens extensively worldwide is chemical control. Nevertheless, this has multiple drawbacks potential hazards, including pathogen resistance, environmental contamination, negative effects on human health other organisms. As logical result, over last decades, conventional agricultural have been questioned transition toward more sustainable methods emerged. new productive paradigm emphasizes adoption of eco-friendly approaches disease management, biofungicides biostimulants tools gaining popularity. establishing regulatory framework for different countries proven challenging due lack harmonization. primary objective review gather dispersed information technologies (either available market or being studied) applicable generated latest scientific advances.
