“…The improvement in the ascorbic acid content of strawberry cultivars might be due to the increase level of metabolites that might have triggered the precursor of ascorbic acid biosynthesis in plants as mulches probably led to differences in soil moisture content, enhanced nutrient availability which in turn affected plant growth, development and strawberry fruit quality. The results are also in concord with the reports of Pramanick et al (2013), Rostami et al (2022), Chakraborty et al (2023).…”

Present study was conducted during 2021-2023 at NICRA adopted village Paiyong, under the aegis of Krishi Vigyan Kendra, Kalimpong to evaluate strawberry (Fragaria × ananassa Duch.) cultivars under the subtemperate condition of Kalimpong. According to the results obtained, we found that cultivar Camarosa significantly exhibited maximum plant height, plant spread, number of leaves, number of runners and flowers per plant, recorded minimum days taken for 50 % flowering and flowering to harvest days, maximum berry weight, highest yield per plant, Total soluble solid, Total sugar and Ascorbic acid respectively followed by cv.Festival whereas, cv. Winter dawn exhibited lowest plant height, plant spread, number of fruits and flowers per plant, recorded maximum days taken for flowering and harvest shown significant decline of yield per plant, pertained minimum Total soluble solids (TSS), Total sugar and Ascorbic acid. As the results indicated that the performance of cv. Camarosawas significantly better in terms of vegetative, yield and yield attributing characters.

“…The positive effect of the combined fertilisation with potassium nitrate (100 mg dm −3 ) and humic acid (40 mg dm −3 ) on the vegetative and reproductive growth, total yield, the content of chlorophyll and nitrogen in leaves in the cultivation of potted cucumbers was also shown by Kazemi [64]. There are also many reports on benefits gained from the application of humic substances in the cultivation of commercial crops, such as sugar cane [3], kiwi [65], hot pepper [66], or strawberry [5].…”

“…According to Stevenson [4], humic substances are a group of heterogenous acids (humic and fulvic ones) and their salts (humates). Humic acids (HA) are built of mainly carbon, hydrogen, and oxygen, in addition to small amounts of nitrogen and sulphur [5]. An important role in humic acids is played by functional groups, which determine the properties of humic acids, such as hydrophilicity, acidity, or ion exchange capacity [5][6][7].…”

Use of Organic Materials to Limit the Potential Negative Effect of Nitrogen on Maize in Different Soils

2022

This study was launched to test organic materials in the form of humic acids (HA) applied to soil to improve the effect of nitrogen on maize, and to determine an optimal dose of HA, which will be ecologically safe and will counteract potential negative (phytotoxic) influences of excessive nitrogen fertiliser doses, on two soils with different textural composition. The maize plants grown on the loamy sand were characterised by a higher value of the SPAD leaf greenness index, yields, and a lower content of total-N and sulphate sulphur in maize. Urea, and especially UAN, promoted higher SPAD leaf greenness index values during the stem elongation stage and particularly during the tassel emergence stage. The effect of urea on maize yields was positive on both soils, but UAN had a positive effect on this parameter only on the loamy sand. HA tended to increase the SPAD leaf greenness index. The impact of HA on plant height and yields (especially medium dose) was generally positive. However, a negative effect of the interaction of HA with UAN on the plant height and maize yield on the sand was observed. HA caused an increase in the total-N content, and their highest dose also decreased the sulphate sulphur content in maize. The application of HA to soil has a positive influence on the growth and development of plants and can create positive effects by mitigating adverse consequences of intensive agricultural production in the natural environment.

“…All these features of humic acid would improve the yield of the product, as well as their quantity and quality. In this sense, several studies have been performed on the effect of humic acid on the yield of different plants [16][17][18][19][20][21], but little information is available about the interaction between HA and bioactive compounds and the effects of these interactions on physiological or biochemical processes.…”

Lettuce (Lactuca sativa L., Asteraceae) is a popular vegetable leafy crop playing a relevant role in human nutrition. Nowadays, novel strategies are required to sustainably support plant growth and elicit the biosynthesis of bioactive molecules with functional roles in crops including lettuce. In this work, the polyphenolic profile of lettuce treated with glutamic acid (GA), humic acid (HA), and their combination (GA + HA) was investigated using an untargeted metabolomics phenolic profiling approach based on high-resolution mass spectrometry. Both aerial and root organ parts were considered, and a broad and diverse phenolic profile could be highlighted. The phenolic profile included flavonoids (anthocyanins, flavones, flavanols, and flavonols), phenolic acids (both hydroxycinnamics and hydroxybenzoics), low molecular weight phenolics (tyrosol equivalents), lignans and stilbenes. Overall, GA and HA treatments significantly modulated the biosynthesis of flavanols, lignans, low molecular weight phenolics, phenolic acids, and stilbene. Thereafter, antioxidant capacity was evaluated in vitro with 2,2-diphenyln-1-picrylhydrazyl (DPPH), 2,2′-Azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), and cupric ion reducing antioxidant capacity (CUPRAC) assays. In addition, this study examined the inhibitory properties of enzymes, including acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), tyrosinase, alpha-amylase, and alpha-glucosidase. Compared to individual treatments, the combination of GA + HA showed stronger antioxidant abilities in free radical scavenging and reducing power assays in root samples. Moreover, this combination positively influenced the inhibitory effects of root samples on AChE and BChE and the tyrosinase inhibitory effect of leaf samples. Concerning Pearson’s correlations, antioxidant and enzyme inhibition activities were related to phenolic compounds, and lignans in particular correlated with radical scavenging activities. Overall, the tested elicitors could offer promising insights for enhancing the functional properties of lettuce in agricultural treatments.
