“…In addition, the other researchers also reported that biofertilizers developed from solid extract of green algae, influenced chlorophyl and proline content, and growth of sunflower plants (Chbani et al ., 2015;Majed et al, 2015). Similar effects of biofertiizers developed from solid extracts, were also reported in vegetable (Li et al, 2017), soybean (Kocira et al, 2018), rice (Sunarpi et al, 2018), cucumber (Sunarpi et al, 2019) and tomato plants (Sunarpi et al, 2020) . Thefe facts are corelated with arguments that the application of biofertilizers containing solid extracts which are rich with essential elements will provide the availability of eesential elements in soil media.…”

“…Solid extract provide essential elements in soil, which are ready to be absorped by root system to support plant hight, tlller number, which ultimately shoot sytem. This phenomena has been reported by many researchers in other plants, maize (Safinaz and Ragaa 2013), Lepidium sativum (Godlewska et al, 2016), rice (Sunarpi et al, 2018), soybean (Kocira et al, 2019), cucumber (Sunarpi et al, 2019) and tomato plants (Sunarpi et al, 2020). However, IAA contained in liquid extract is not enough quantity to stimulate the growth of shoot system of rice plants.…”

An exessive use of inorganic fertilizers in agriculture cultivation system causes many disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and harm our environment. Therefore, it is needed to find out raw materials for development of organic biostimulant and biofertilizer inducing essential element absorption, growth and yield of plants, which are adaptive to our environment as well. Previous researchres reported that seaweed contained plant growth hormones and essential elements in liquid and solid extracts respectively. This article reports effect of solid and liquid extracts of Sargassum cristafolium on growth and yield of rice plants. The extracts were extracted according to modified procedure.. Solid extract (350 gr) of Sargassum cristafolium was mixed with soil (6650 gr) to become 7 kg soil media. Moreover, liquid extract (10%) of Sargassum cristafolium was sprayed to rice plants once a week during vegetative growth. The results shown that addition of 350 gr of solid extract to soil media increased growth (plant high, tiller number, shoot dry weight and root dry weight) and yield (penicle number and grain weight per plants) significantly compared with those of plants which were not supplied with solid extract. However, spraying liquid extract of Sargassum cristafolium did not affet significantly growth and yield of rice plants, even small change happen in growth and yield parameters of the rice plants supplied with solid extract. This indicates that solid extract is a potential source for development of biofertilizer which is adaptive to our environment to support sustainable agriculture system.

“…However, brown seaweeds such as Sargassum species have drawn much attention due to their fast-growing nature [7]. This is possibly due to the presence of plant growth hormones in Sargassum species, which potentially contributes to its rapid growth [8,9]. Seaweed has been reported to be extremely rich in nutrients, including macro-and micronutrients, which could balance the plant's endogenous hormones and greatly promote growth [10].…”

Excessive use of chemical fertilizer could potentially decrease soil productivity by decreasing soil microbiome diversity. In this study, we evaluated the effects of fermented seaweed fertilizer in the soil microbial community of paddy plants (Oryza sativa L.). The paddy seedlings were divided into five groups, control (C0), chemical fertilizer (CF), seaweed fertilizer (SF), chemical and seaweed fertilizer combination 50:50 (CFSF1), and chemical and fertilizer combination 75:25 (CFSF2). The CFSF1 combination showed to be the most effective in inducing plant height (83.99 ± 3.70 cm) and number of tillers (24.20 ± 4.08). After 8 weeks after transplantation, the isolated DNA from each soil treatment were subjected to 16S rRNA (v3–v4 region) next-generation sequencing. The beneficial Acidobacteriota was most abundant in CFSF1. At genus level, the nitrifying bacteria MND1 was seen to be abundant in CFSF1 and also present in other SF treatments. The genus Chujaibacter is highly abundant in CF, which potentially plays a role in denitrification resulting in soil degradation. In addition, the CFSF1-treated soils show significantly higher diversity of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). The current results could potentially contribute to the utilization of SF as a bioremediator and promoting green agriculture practice by reducing the amount of CF usage.

BACKGROUNDThe use of pesticides in greenhouse vegetable cultivation is necessary and significant. However, traditional pesticide application methods such as the use of backpack sprayers with water‐diluted pesticides have certain drawbacks, e.g., uneven distribution, high labor intensity, and safety risks.RESULTSIn this work, fluazinam ultra‐low‐volume liquids (Flu‐ULVs) were prepared using oily solvents as carriers. The effects of different oils on the physical properties of the preparations were investigated. The Flu‐ULV can be sprayed directly using a hand‐held ultra‐low‐volume (ULV) sprayer without dilution with water. Compared with commercial water‐based suspension concentrates of fluazinam, the Flu‐ULV samples showed better wetting of tomato leaves, better atomization, and more uniform droplet distribution. At a dosage of 300 mL/ha, the coverage rate of tomato leaves ranged from 32.47% to 79.3%, with a droplet deposition density of 556 to 2017 droplets/cm2. Application of Flu‐ULVs provided 70.86% control efficacy against gray mold in tomatoes, which was higher than those achieved with reference products. Dermal exposure to Flu‐ULVs was also evaluated in greenhouse experiments. The coverage rates for all parts of the operator's body ranged from 0.02% to 0.07%, with deposition volumes of 2.23 to 12.26 μg/cm2.CONCLUSIONGround ULV spraying of fluazinam was proved to be an effective and safe management option for the control of tomato gray mold in greenhouses. This study laid a foundation for the use of ultra‐low volume spray to control vegetable diseases in greenhouse, especially those induced by high humidity environment. © 2024 Society of Chemical Industry.
