Optimizing Lead Phytoextraction from Metal-Enriched Water Using Arundo donax: A Response Surface Methodology (RSM) Approach
Phytoremediation is a sustainable and eco-friendly approach that uses plants to remove water contaminants. It shows great promise in addressing water pollution. The aim of this study is to evaluate the effectiveness of phytoremediation in treating water contaminated with various pollutants. The study specifically investigates the impact of ethylenediaminetetraacetic acid (EDTA) on the growth and physiology of Arundo donax, a plant used in lead (Pb) phytoremediation. Response surface methodology is used to optimize experimental conditions to maximize Pb removal by Arundo donax. The results demonstrate that the use of EDTA enhances the solubility of Pb in water, making it easier for the plant's roots to absorb it. There are significant correlations between the concentrations of Pb, the time of sampling, the use of EDTA, and the amount of Pb eliminated. The validity of our model and the significance of the studied factors were confirmed through analysis of variance (ANOVA). The results highlight the potential of using EDTA-assisted Arundo donax for Pb phytoremediation. This research contributes to the development of sustainable and efficient methods for mitigating Pb-induced water contamination, which is crucial for protecting human health and the environment.
Nutrient composition of ghee residue and their digestibility in chicken
Ghee residue is a by-product of dairy-industry involving in manufacture of ghee. Ghee residue was analyzed for its proximate composition, gross and metabolizable energy content, complete amino acid, fatty acid and mineral profiles. It was also assessed for apparent digestibility of crude protein, amino acids and retention of minerals in poultry. The dry matter, crude protein, ether extract and total ash contents (per cent) in ghee residue were 90.19, 25.71, 51.35 and 4.83 respectively, with no crude fibre. The gross energy of ghee residue was 7279 kcal/kg. The lysine, methionine, threonine and arginine contents in ghee residue were 0.98, 0.51, 1.28 and 0.79 per cent, respectively. The linoleic and linolenic acid contents of ghee residue were 2.22 and 0.33 per cent of fat, respectively. The calcium, phosphorus and magnesium content were 0.78, 0.72 and 0.73 per cent, respectively. The content of copper, iron, manganese and zinc in ghee residue were 18.18, 138.26, 9.47 and 28.97 mg/ kg, respectively. The apparent and true metabolizable energy content of ghee residue were 5570 and 5839 kcal/kg ghee residue, respectively. The apparent digestibility of crude protein was 67.96 per cent and the digestibility of lysine was found to be the lowest (66.86 per cent) among amino acids. The mineral retention study revealed that the retention of calcium, phosphorus and magnesium were found to be 57.40, 44.55 and 88.80 per cent, respectively. Similarly, the retention coefficient of copper, iron, manganese and zinc were 55.10, 57.99, 36.58 and 35.06 per cent, respectively. The finding revealed the potential of ghee residue as an energy as well as protein source and suggested that ghee residue may conveniently be considered as an alternative source of high energy poultry feed ingredient and simultaneously as a good protein source when supplemented with limiting amino acids.
Dietary supplementation of lemongrass oil and thyme oil on performance, gut health, nutrient digestibility, cholesterol and economics of production of broiler chicken
Two hundred and fifty six broiler chicks were randomly grouped into eight treatments and were fed diet without (T1) or with supplementation of antibiotic growth promoter (T2), or with supplementations of lemongrass oil at 100 mg/kg diet (T3), 200 mg/kg diet (T4), 300 mg/kg diet (T5) or thyme oil at 100 mg/kg diet (T6), 200 mg/kg diet (T7) and 300 mg/kg diet (T8). The experiment revealed that T1 had significantly lowest body weight and weight gain among all treatment groups. The groups T3, T4, T6 and T8 did not differ significantly with T2, whereas, T7 and T5 had significantly higher body weight gain than T2 and control. No significant difference was observed among treatments groups in cumulative feed intake. At the end of experimental period, the feed conversion ratio of broilers was significantly better in T7 followed by T5 and T8, than T6, T4, T3 and T2, whereas the control (T1) recorded poorest feed conversion ratio. There was no significant difference in livability among treatment groups. The group T8 had significantly higher villi length followed by the groups T7 and T6 than other treatment groups, whereas it was lowest in T2. All the groups fed with the essential oils recorded significantly higher apparent digestibility of protein and retention of calcium and phosphorus than T1 and T2. The groups T5, T4, T3 had significantly lower total cholesterol in serum, breast and thigh muscle than control (T1) and antibiotic supplemented group (T2). Return over feed cost was highest in T7 and it was lowest in control group. The supplementation of antibiotic (T2) increased the return-over-feed cost (ROFC) than control. The groups T3 and T6 produced comparable ROFC with T2, but T4, T5 and T8 produced higher ROFC than T1, but lesser ROFC than T2. Hence, it may be concluded that lemongrass oil up to 100 mg/kg or thyme oil up to 200 mg/kg broiler diet could be supplemented as an alternate to antibiotic growth promoter, without compromising the economics of broiler farm.
Effect of Some Preservative Solutions on Keeping Quality and Vase Life of Cut Narcissus Flowers (Narcissus tazetta L)
The vase life of cut Narcissus flowers is generally short due to bent neck and wilting. This study was conducted to determine the effects of different concentrations of PBZ (0, 30, and 60) mgL-1 and CuSo4 (0, 150, 250) % on the vase life and their interaction on relative fresh weight, and water uptake of cut narcissus flowers (Narcissus tazetta L). Distilled water was used as the control. The analysis of length variances conducted on the effects of Paclobutrazol (PBZ) and Copper sulfate (CuSo4) on the duration of petal freshness the results showed that the different length of Narcissus flowers (20 and 30) cm significantly affected the length of narcissus flowers (20) cm gave the higher value 8.556 days compared to the 30 cm length gave 8.037 days. The maximum significantly delayed petal freshness shows when put the cut flower on preservative solution containing 150 % of CuSo4 which give 8.458 days. About the different concentration of Paclobutrazol (PBZ) which effected significantly on vase life, relative fresh weight and water up take the 30 mgl-1 obtaining a higher value 10.627 days, 57.722 g and 94.980 g. While the lower value of vase life obtained on 60 mgl-1 reached 10.508 days. About the interaction between the different level of CuSo4 and different concentration of PBZ on all parameter such as duration of petal freshness, vase life observed the maximum value reached 8.917 days, 11.515 day respectively when put the cut narcissus flower for 30 cm on jar containing 0 PBZ combine with 150 % CuSo4. Also, the relative fresh weight and water uptake give the maximum value when put the flower 20 cm length on jar containing 60 mgl-1 PBZ combine with 150 % CuSo4 and 30 mgl-1 combine 150 % reached 125.797 and 63.333 g respectively.
Impact of Conservation Agriculture Practices on Soil Health and Crop Productivity under Millet-Based Cropping Systems: Review
Conservation agriculture (CA) practices have emerged as sustainable alternatives to conventional agriculture, particularly in the context of millet-based cropping systems. Many studies now available worldwide show the capacity of conservation agriculture (CA) as a sustainable system to overcome negative consequences on soil health, to prevent soil degradation and to guarantee food security. Soil health is a term used to describe the general state or quality of soil, and in an agroecosystem, soil health can be defined as the ability of the soil to respond to agricultural practices in a way that sustainably supports both agricultural production and the provision of other ecosystem services. Furthermore, CA can preserve the production and supply of soil ecosystem services while lessening the detrimental effects of traditional agricultural methods on soil condition. Agricultural development today presents before unheard-of difficulties; CA is therefore very important for the sustainability of intensive farming. Reduced tillage together with crop residue retention could lower fixation of P in soil, improve labile P content and enhance organic-P (Po) accumulation and its mineralization by phosphatases; this could be an additional benefit of conservation agriculture (CA) in soils. Currently, there are many evidences throughout the world that demonstrate the capability of conservation agriculture (CA) as a sustainable system to overcome these adverse effects on soil health, to avoid soil degradation and to ensure food security.
