“…Organic spinach contains more phenolics compared to conventional ones. Therefore, organic samples were characterized by a higher antioxidant power than conventional spinach [64]. In the present experiment, we found a strong interaction between cultivation methods and years.…”

Bioactive compound profiles in organic and conventional sweet basil were analyzed by HPLC, and the enzymatic status and antioxidant status of plants cultivated with the two systems were also examined. Fluorescence microscopy was used for the determination of compounds’ locations in the basil leaves. The experiment was conducted from 2019 to 2021. Organic and conventional basil samples were obtained directly from Polish herb producers. The results showed that the chemical profiles of organic and conventional basil leaves are different. Not only the cultivation method but also the experimental year had a significant impact on the antioxidant content in basil leaves. Organic basil contained significantly more dry matter (11.97 g 100 g−1 FW) compared to conventional one (10.54 g 100 g−1 FW) and a higher tendency for total phenolic compounds (5.24 mg g −1 DW) accumulation. The higher bioactive compound content reflects the antioxidant activity (61.0%, 54.33%, and 46%) in organic basil compared to conventional (46.87%, 38.055, and 39.24%) with respect to the analysis method (ABTS, DPPH, and FRAP). Catalase activity (39 µmol H2O2 min−1 mg−1) in organic basil was higher compared to conventional (23.19 µmol H2O2 min−1 mg−1) ones. The obtained results are very unique and could be used by herb producers as a key for high-quality basil production. The higher concentration of bioactive compounds in organic basil gives a better nutraceutical status to this popular herb.

“…Exposure to ultraviolet radiation (Rozema et al, 1997), environmental stresses (Ehrhart, 2014), allelopathic interactions (Mann et al, 1987), and availability of nutrients in the soil could also stimulate the biosynthesis of these natural products. It has also been shown that the levels of fertilization in nitrogen, phosphorus, potassium and calcium can affect the production of secondary metabolites in plants (Oloyede et al, 2012;Sabrina et al, 2012;Omar et al, 2012;Vignesh et al, 2012), and therefore that the presence of macronutrients is essential for plant growth and has a significant effect on the accumulation of polyphenols and antioxidants (Parr et al, 2000).…”

The availability of secondary metabolites in various plant parts can be influenced qualitatively and quantitatively by managing ecological factors or farming practices. Purpose of this study was to determine the impact of organic and mineral fertilization on the content of phenolic compounds and antioxidant activity in fruit of the tomato Mongal F1 variety. Experimentation was carried out in a randomized block factorial design. Results of study revealed that plant treated by organic fertilizers have 16.36± 0.07mg Trolox Equivalent (TE)/100g fresh tomato (ft) antioxidant activity and 6.96± 0.63mg Gallic Acid Equivalent (GAE)/100g ft total phenols content while the plant treated by mineral fertilizer have 15.57± 0.05 mg TE/100g ft for antioxidant activity and 6.09± 0.13mg GAE/100g ft for total phenols content. Furthermore, it was reported that, as compared to mineral fertilization, organic fertilization significantly increases the antioxidant activity and phenolic compounds production in Mongal F1 tomato variety. This increase is probably due to the availability of various major and minor elements in organic fertilizer contrary to mineral fertilizer which has only three major elements, nitrogen, phosphorus, and potassium. 79 days after transplanting, fruit ripping has no obvious effect on the accumulation of these compounds.

“…The results are in conformity with El-Sabour et al, 1997 who also found increased chlorophyll content of leaves in Helianthus annus (sunflower) when soil was treated with organic compost. Vignesh et al (2012) observed increased chlorophyll concentration and antioxidant activity of spinach leaves under organic fertilizer amendments.…”

The present investigation was aimed to assess the influence of different organic manures (Farmyard manure and vermicompost), inorganic fertilizers and Azophos biofertilizer on different physiological attributes of tomato. The field experiment was conducted during 2005-06 and 2006-07 at Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India by combining 14 treatments in randomized block design with 3 replications. The results revealed that nutrient sources significantly influenced different physiological attributes as the chlorophyll content of leaves and LAI (Leaf area index) kept on increasing and peaked at 60 DAT(Days after transplanting) and 75 DAT respectively and declined thereafter. The dry matter production was highest at 75 DAT. Again application of vermicompost (4 t/ha) with 75% of inorganic fertilizers inoculated with biofertilizer resulted in significant improvement of physiological attributes as well as yield. Vermicompost emerged as better organic nutrient source over farmyard manure. Inoculation with biofertilizer exerted more positive results over uninoculated treatments and benefits of biofertilizer application were more in presence of vermicompost as compared to farmyard manure.
