Economics of Cabbage Production Under Different Levels of Integrated Nutrient Management in Varanasi Region of Uttar Pradesh, India

The excess use of chemical fertilizers is hazardous for soil and environmental health. To reduce the level of chemical fertilizers the field experiment was conducted during Rabi season of 2016-17 at horticulture research farm, Department of Horticulture, U. P. College, Varanasi (Uttar Pradesh). The experiment was laid out in a randomized block design (RBD) with nine treatments. These treatments were replicated thrice. The treatments included various levels of NPK, FYM, vermicompost, Phosphorus Solubilizing Mycorrhiza. Economic analysis of different treatments of cabbage production in Varanasi region (Uttar Pradesh) revealed variation in net capital investment. The results show that among different integrated nutrient management (INM) levels, half dose of NPK ha-1 + Vermicompost @ 2.5 tons ha-1 + Azospirillum @ 5kg ha-1 + Phosphorus Solubilizing Mycorrhiza @ 5 kg ha-1 has highest net return followed by half dose of NPK ha-1 + FYM @ 15 tons ha-1 + Phosphorus Solubilizing Mycorrhiza @ 5 kg ha-1 + Azospirillum @ 5 kg ha-1. Lowest net return was observed with half dose treatment of NPK ha-1 + FYM @ 15 t ha-1. Cabbage crop nutrition by supplying recommended dose of NPK ha-1 (150 kg: 125 kg: 100 kg) recorded highest cost-benefit ratio (3.11) while, half dose of NPK ha-1 + FYM @ 15 t ha-1 gives lowest cost-benefit ratio (2.05) among the all INM levels.

Impact of Elevated Ozone on Cabbage

Tropospheric ozone (O3) is a pervasive greenhouse gas and air pollutant known for its detrimental effects on human health and vegetation. In the recent years, tropospheric ozone has been rising steadily on the account of rapid urbanization and globalization. Hence, a study to investigate the impact of elevated ozone levels on cabbage cultivars have been initiated. The cultivars Tekila and Primero, which are extensively grown in the high-altitude region of the Western Ghats, India were used as test crop, where ozone levels are a growing concern. The study employed a comprehensive experimental design, encompassing ozone stress (200 ppb), cabbage varieties (Tekila and Primero), and different growth stages of the cabbage plants. Ozone fumigation at 200 ppb was used to simulate elevated ozone conditions, reflecting potential future scenarios. To assess the extent of impact both physiological and biochemical parameters were extensively analyzed. The results revealed that elevated ozone concentrations had a significant negative impact on both cabbage cultivars. Photosynthetic rate, stomatal conductance, and chlorophyll content declined progressively as ozone exposure continued, leading to maximum reductions of 71.2, 81.03 and 32.98% respectively. However, protective mechanisms were activated in response to ozone stress, including increased proline by 32.24%, ascorbic acid by 64.75%, catalase by 3.58%, and peroxidase activities by 56%, suggesting the cabbage plants' efforts to mitigate oxidative damage. Overall, this study highlights the vulnerability of cabbage cultivars to elevated ozone levels and emphasizes the need for effective mitigation strategies to safeguard crop productivity and ensure sustainable agriculture in regions facing escalating ozone pollution. Further research is essential to develop and implement solutions that can protect vital crops like cabbage from the adverse effects of tropospheric ozone.

Characteristics of Vegetable Juice Fermented with Lactobacillus plantarum MKHA15 and Leuconostoc mesenteroids MKSR

The objective of this study was to develop fermented vegetable juices that possess antidiabetic and antioxidant activities. Lactobacillus plantarum MKHA15 (MKHA15) and Leuconostoc mesenteroides MKSR (MKSR) were applied to ferment onion, cabbage, and tomato juices at 37℃ and 30℃ for 72 h, respectively, and their functionality was tested using the 12 h hour-fermented juice by MKHA15, and 48 h hour-fermented juice by MKSR. Inhibition of α-glucosidase activity was observed in all fermented juices. The onion juice fermented by MKHA15 showed significantly higher α-glucosidase inhibition activity compared to other juices. All juices showed more than 70% inhibition of α-amylase activity. The DPPH radical scavenging activity of onion juice fermented by MKSR showed significantly lower activity than cabbage and tomato juices; however, no difference was observed between the types of starter cultures. The SOD-like activity of cabbage juice fermented by MKSR was the highest among the fermented juices. The juices fermented by MKHA15 showed higher reducing power than those by MKSR. Therefore, we believe that cabbage, onion and tomato juice fermented by MKHA15 and MKSR would be useful in probiotic juices, as they possess antidiabetic and antioxidant activities.

Formulation and Charcterization of Lake Color Obtained From Red Cabbage.

Colorants are mainly used to impart a distinctive appearance to the pharmaceutical dosage forms. The present study was carried out to develop aluminium lake color of a dye obtained from red cabbageusing different adsorbent (s) (Aluminium oxide or aluminium hydroxide or combination of both) in different ratio by simply mixing them to get dye adsorbed onto the surface of adsorbent.Batch Mode studies were carried out for 60 minutes. Aluminiumhydroxide at a concentration level of 30% w/v found to be the choice of adsorbent after optimization because maximum adsorption of dye from reaction mixture after 60 minutes and maximum % yield.After optimization of adsorbent the effect of pH and temperature also studied by formulating lake by varying these two parameters. It was observed that a higher temperature (50oC) and a slight acidic pH (6) favor the adsorption. The lake then characterized for various physicochemical properties like angle of repose, Carr’s index, hausner’s ratio, loss on drying, particle size and limit test for heavy metals. The lake was found to follow pseudo second order kinetics.

Cytoprotective and antiinflammatory effect of polyphenolic fraction from Red cabbage (Brassica oleracea Linn var. capitata f rubra) in experimentally induced ulcerative colitis.

In present study we investigated the anti-inflammatory effect of polyphenolic fraction isolated from Red cabbage Brassica oleracea Linn var. capitata f. rubra (PBO) on lipoplysacharide (LPS) stimulated HT-29 colonocytes and in rats with acetic acid induced colitis. Our results from in vitro studies demonstrated that PBO effectively attenuated the inflammatory response produced by cycloxygenase (COX), 5-lipoxygenase (5-LOX) and oxidative stress created via reactive oxygen species (ROS) and nitric oxide (NO) in LPS treated HT-29 cells. Additionally PBO down regulated the mRNA expression of inflammatory marker genes like COX-2, inducible nitric oxide (iNOS) tumor necrosis factor α (TNF-α), interleukin-6 (IL-6) in HT-29 cells. PBO at a dose of 200 mg/kg body weight was tested in treatment groups of animals (n = 6) for 14 consecutive days after induction of colitis. The colonic mucosal injury was assessed by histological examination. Moreover, PBO administration markedly increased the mucin content as evidenced in periodic acid Schiff (PAS) staining and the mucosal content of lipid peroxidation (LPO), confirms that PBO could significantly inhibit colonic mucosal damage. These results indicated that PBO exert marked anti-inflammatory effect in experimental colitis, possibly by regulating the antioxidant and inflammatory mediators.

LED Lights Enhance Metabolites and Antioxidants in Chinese Cabbage and Kale

Light emitting diode (LED) lights play an important role in the plant physiology and alter the metabolites in a significant manner. Glucosinolates (GSLs), polyphenols, flavonoids and antioxidant properties of Chinese cabbage and kale cultivated in varying LED lights were investigated. Analysis revealed 7 aliphatic, 3 indolyl and 1 aromatic GSLs in Chinese cabbage and kale. The total GSL content ranged from 1.5-19.08 and 1.85-24.87 µmol/g DW, and glucobrassicanapin was the predominant GSL (3) in Chinese cabbage, whereas; sinigrin (3.49 µmol/g DW) was in kale. Blue and red LED lights produced significantly higher amount of GSLs in Chinese cabbage and kale respectively. Results revealed higher amount of total polyphenol (3.845 µg/mL) and total flavanoids (3.939 μg/mL) in Chinese cabbage. Chinese cabbage and kale showed significant antioxidant activities when compare with positive control, and the antioxidant assays were slightly correlated with total GSLs, polyphenols and flavanoids contents. The influence of LED lights on glucobrassicin in Chinese cabbage and kale should be studied extensively, because GSL is the precursor of indole-3-carbinol, a potent anticancer isothiocyanate.

Encapsulation of Red Cabbage (Brassica oleracea L. var.capitata L. f. rubra) Anthocyanins by Spray Drying using Different Encapsulating Agents

ABSTRACT This study aimed to evaluate the influence of the drying air temperature (140 and 160°C) and the concentration of encapsulating agents gum Arabic and polydextrose (10 and 15%) on the physicochemical characteristics of the red cabbage extract obtained through extraction in acidulated water and drying using a spray dryer. The anthocyanin retention, antioxidant activity, water activity, solubility, color and microstructure of the final product were analyzed. Results showed that increase in the temperature did not cause significant changes in the anthocyanin quantity and antioxidant activity. The microscopic analysis revealed that for both the encapsulating agents, the absence of fissures and porosity in the particle surfaces produced powder with high solubility in water. The principal component analyses showed a strong correlation between the anthocyanin content and the antioxidant activity (r = 0.82) and luminosity (r = 0.81).
