Abstract:

Onion (Allium cepa L.), a globally cultivated vegetable crop, possesses a shallow root system, making it vulnerable to abiotic stresses. The increasing frequency of extreme weather events in recent years necessitates sustainable solutions to enhance onion growth. Biostimulants offer a promising and accessible approach to promote onion growth and quality in an environmentally friendly and sustainable manner. This study investigated the effects of nine commercial microbial biostimulants (LALRISE Mycorrhizae, LALRISE Bacillus, Mighty Mycorrhizae, MycoApply, Spectrum DS, Spectrum Myco, Spectrum, T

Abstract:

The parasitism of root-knot nematodes, Meloidogyne spp., can cause heavy yield losses to vegetable crops. Plant biostimulants are often reported for a side-suppressive effect on these pests and many commercial products are increasingly included in sustainable nematode control strategies. Source materials of most biostimulants derived from plant or seaweed raw materials were documented for a reliable suppression of root-knot nematode species, whereas the suppressiveness of microbial biostimulants was found largely variable, as related to the crop and to environmental factors.

This study was to determine if AMPEP and Kelpak can induce thermal resistance in<i> Pyropia yezoensis</i>. <i>P. yezoensis</i> blades were exposed to different concentrations (control: 0, low: 0.001, high: 1 ppm) of AMPEP and Kelpak at 10°C for 6 and 7 days, respectively. Those blades were then cultivated in von Stosch enriched seawater medium at different temperatures (10, 15, 20, and 25°C) with 12 : 12 L : D photoperiod a

Abstract:

Although advanced production systems have been developed in the last 20 years, water scarcity is still a growing problem in agriculture. This study aims to evaluate the effect of different strategies that combine the application of seaweed and microbial biostimulants with regulated deficit irrigation (RDI) strategies on the irrigation water productivity (WPI), fruit quality parameters and soil enzymatic activity in pepper plants (Capsicum annum sp.) under two commercial greenhouse conditions. In each trial, two treatments were applied: (i) irrigation according to Farmer criteria without biosti

Abstract:

Biological control agents and biostimulants are niche sectors within the Crop Protection and Plant Nutrition sectors which are experiencing rapid growth, driven by an increasingly favourable regulatory environment, growing pest resistance to conventional products, the pull for sustainable agriculture and technological advances. Whilst there are now more BCAs registered than conventional CP products the products also have some limitations compared with conventional products and the sector remains confined mainly to fruit and vegetables, both indoors (protected crops) and outdoors.

Abstract:

Ecklonia maxima is a brown algae seaweed largely harvested over the last years and used to produce alginate, animal feed, fertilizers, and plant biostimulants. Their extracts are commercially available in various forms and have been applied to many crops for their growth-promoting effects which may vary according to the treated species and doses applied. The aim of the study was to characterize the effect of adding an Ecklonia maxima commercial extract (Basfoliar Kelp; 0, 1, 2, and 4 mL L−1) to the nutrient solution of a hydroponic floating system on growth, yield, and quality of leaf lettuce

Biostimulants and rooting enhancers, i.e., auxins, affect many aspects of plant development. The experiment in this paper focused on the response of single-node rose semi-woody cuttings to rhizogenesis-enhancing preparations based on plant extracts in terms of changes in polyphenolic acid content. The shoots were cut at four stages of flowering development: (i) flower buds closed, (ii) open flower, (iii) immediately after petal shedding, (iv) 7–14 days after petal shedding. The experimental material consisted of six old, once-flowering rose cultivars (‘Duchesse d’Angoulême’, ‘Hurdals’, ‘Maiden

Abstract:

In the horticultural sector, the achievement of an efficient and eco-friendly sustainable production of plants is nowadays challenging. Indeed, in plant vegetative propagation of woody ornamentals, the substitution of chemical products used to promote rooting of cuttings with natural extracts would be a desirable goal. Thus, the aim of this work was to test the replacement of synthetic phytoregulators, such as auxins and brassinosteroids, with biostimulants, such as seaweed extracts, for the rooting promotion of rose cuttings.

The cultivation of walnuts (Juglans regia L.) has become increasingly popular worldwide due to the nutritional value of the nuts. Plant biostimulants (PBs) and nutrient-rich products have been increasingly used in agriculture to improve yield, quality, and abiotic stress tolerance. However, farmers need fast laboratory studies to determine the most suitable treatment per crop or ecosystem to take full advantage of these products. Evaluating nucleolar activity and protein content can provide clues about the most appropriate treatment. This study aimed to determine how five commercial products,

Many researchers have been studying seaweed for more than seven decades. According to our needs, research has been done separately in different aspects. There are several chemical fertilisers commercially available today, but they significantly reduce or harm soil fertility, growth, and yield. The amount of fertiliser needed by the plant or crop will determine the fertility of the soil. When compared to terrestrial foods, the seaweed fertilisers had a lot of nu
