Background: Moringa oleifera pods are the main constituent in typical diets throughout Thailand. Due to their nutrients and phytochemicals, moringa pods have potential as an antioxidant and anti-inflammatory agent. Freeze drying is a widely embraced method known for extending shelf life, resulting in preserved nutrients and high-quality products. Objective: This study aimed to investigate the physical properties, nutrients, and bioactive compounds of freeze-dried moringa pods as well as their anti-inflammatory effects on lipopolysaccharide-induced Raw 264.7 macrophages. Methods: Moringa pods were freeze-dried and ground. The powders were extracted with 70% ethanol at room temperature for 24 hr. and then centrifuged at 5000 rpm and 25áµ’C. The supernatant-filtered extracts were collected to determine bioactive compound contents and antioxidant as well as anti-inflammatory properties. Results: The results illustrated that freeze-dried moringa pod extract had bioactive compounds including genistein synthetic, trans-ferulic acid, p-Coumaric, myricetin, gallic acid, and syringic acid, which demonstrated antioxidant activity. In terms of anti-inflammatory effects, 50-200 Âµg/ml of extract inhibited pro-inflammatory mediators including NO production and IL-6 and TNF-Î± levels on LPS-induced Raw 264.7 macrophages. Results: These results indicate that the antioxidant and anti-inflammatory properties of freeze-dried moringa pods make them a promising new raw material for functional product development. Keywords: Anti-inflammation, Moringa oleifera, genistein synthetic, trans-ferulic acid, p-Coumaric, myricetin, gallic acid, syringic acid.

“…Phosphorus (P) is a very important nutrient for plants placed aer nitrogen (N) and a restriction factor (Balemi & Negisho, 2012;Mustonen et al, 2012;Paisey & Santosa, 2023). Phosphorus is intimately engaged in numerous plant metabolic processes, and its deficiency appears to be the primary reason for low yield.…”

The idea of a critical limit (CL) of nutritional elements distinguishes deficiency from adequacy, which could suggest fertilizer administration. The critical limit can be used to distinguish between responsive (deficiency) and non-responsive (sufficiency) sites. The study aims to estimate the critical limit of phosphorus (P) for mustard and maize in different Agro-ecological Zones (AEZs) of Bangladesh. In this context, the study was conducted in 20 types of soil and two crops (maize and mustard) both in pot and field experiments. Twenty soils from different places were used as experimental materials, among them 12 soil samples had inadequate soil fertility, 4 had low fertility, and the remaining 4 had medium levels of fertility. The treatments were two crops: BARI Hybrid Maize 7 (Maize) and BINA Sharisha 9 (Mustard) and two levels of phosphorus (P): 0 and 15 ppm. Dry matter (DM) yield was calculated and the nutritional content of plant samples was determined. Depending on the chemical properties of the soil, the results ranged from extremely low to very high levels. Reading the mustard crop, the estimated critical levels of P were found to be 14.8 ppm (graphical) and 18.9 ppm (statistical). Regarding the maize crop, the estimated critical P levels were found to be 14.5 ppm (graphical) and 12.3 ppm (statistical). When soil P is less than the CL, plants respond to P-based fertilizer effectively. The results of the trials will assist in managing P fertilizer for the sustainability of maize and mustard production in diverse soil types in different agroecological zones of Bangladesh.

Phosphorus and potassium are essential nutrients for plant growth and development. Plants will achieve optimum biomass and production if phosphorus and potassium needs are met through fertilization. Determining the availability of phosphorus and potassium in the soil is essential because it is related to decisions on phosphorus and potassium fertilizer rate recommendations. In this study, we evaluated 5 common phosphorus and potassium extraction methods by correlating the indicated soil nutrient levels to the relative biomass dry weight of tomato plants. The phosphorus and potassium extraction methods used were Mehlich-1, Bray-1, Morgan-Wolf, Ammonium acetate, and HCl-25%. Mean Root Error (MRE) and Root Mean Square Error (RMSE) were used to determine the precision of the linear regression equation model in predicting the relationship between phosphorus and potassium soil extraction methods and the relative biomass dry weight of tomato plants. The correlation of the soil extraction methods used in Andisols with the relative biomass dry weight of tomato was highly significant and very strong (r > 0.75) suggesting that Bray-1 was the best soil-phosphorus extraction method (Pr = 0.88; PMRE = 0.10; PRMSE = 4.44), while HCl-25% was the most suitable for soil-potassium extraction (Kr = 0.90; KMRE = 0.05; KRMSE = 2.95). The results of the two extraction methods will be used to determine the dosage of phosphorus and potassium fertilizers (nutrient sufficiency approach) for tomato plants grown in Andisols.
