Green synthesis of copper nanoparticles mediating Curcuma caesia Roxb. leaf extract and assessment of its antifungal activity against Colletotrichum capsici
The copper nanoparticles were synthesized using the leaf extract of black turmeric (Curcuma caesia Roxb.) and were characterized using UV-VIS spectrophotometer, DLS, NTA, SEM, and FTIR. The biosynthesized CuNPs showed an SPR peak in the range of 225-230 nm. The NTA results revealed the size of CuNPs to range from 100 to 200 nm. DLS measurements showed CuNPs synthesized at 300C reaction temperature produced NPs of size 116.8 nm and had a zeta potential of -21.7 mV. SEM studies revealed the morphology of copper nanoparticles as irregular rod-like structures arranged in a flower-like pattern. FT-IR analysis confirmed the presence of functional groups, viz., OH, C-H, N-H, C-N, and C=C, which triggered reduction of copper ions to CuNPs. The CuNPs showed antifungal activity against Colletotrichum capsici and showed maximum growth inhibition (63.93%) at 500 ppm concentration. The mode of action of CuNPs against the fungal pathogen was divulged by NBT staining, quantification of MDA, leakage of intracellular components, antioxidant enzymes and light microscopy. The results confirmed the generation of ROS, causing membrane lipid peroxidation, leakage of intracellular components, causing distortion and death of the fungus. The field experiment reported that CuNP successfully reduced the disease severity of leaf spot of turmeric. The treatment T6 (Rhizome treatment with CuNPs @ 100 ppm and foliar spray with CuNPs @ 100 ppm, thrice at 21 days interval) showed lowest disease severity (34.4 %) with maximum yield (20.98 t/ha). Thus, results from this study provides alternative solution for management of leaf spot of turmeric.
Quantitative Evaluation of Soil Quality Based on Soil Nutrients and Physico-chemical Characteristics of Soils in Kandi District of Punjab
Kandi regions are dominated by different soil types varying in fertility status due to soil erosion owing to undulating topographical features. For assessment of soil nutrient status of study area, the soil sampling was conducted to investigate the variation in macro nutrient, micronutrient and physicochemical characteristics of soil. Soil sampling were carried out in three tehsils of SAS Nagar with three different types of soil, viz., Sandy loam, Silt loam and Loam soil. A total 105 soil samples were collected from surface soil (0-15 cm) for analysis. The results reported that the soils slightly acidic to slightly alkaline (5.9 to 8.5) in the whole range. Organic carbon (OC) was found to be varying from low to very high (0.18 to 0.78 %). Phosphorus and sulphur were significantly found Silt loam soil. DTPA-extractable Fe, Mn and Cu were found to be dominant concentration in all soils whereas the deficiency of Zn was found under all existing soil types. Interestingly, OC have also significant positive correlation with Nitrogen (r = 0.353), Sulphur (r = 0.212), Zinc (r = 0.257) and Iron (r = 0.327). Soil quality based on principal component analysis reported Fe, Cu, Mn, EC and K are major dominating parameters to be considered of soil in Kandi region.
Validation of Ethno Veterinary Medicines Used for Retained Placenta Treatment in Cattle
Ethnoveterinary medicines play a significant role in traditional dairy farming practices. Ethnoveterinary medicines are often used by traditional dairy farmers to manage various aspects of animal health. There is every possibility of extinction of traditional knowledge in rural areas. Hence it is the need of the hour to document the prevailing traditional knowledge of various ailments of cattle. One such ailment is retained placenta. A survey was conducted with 40 representative farmers who were practicing ethno veterinary medicines to treat retained placenta were selected purposefully from 4 districts of Tamil Nadu in India to validate the different ethnoveterinary medicines used to treat retained placenta in cattle and also comparing the present ITKs with the Modern Veterinary drugs for treatment of retained placenta in cattle. A sample of 40 farmers were interviewed through structured interview schedule to document the ITK’s used for treatment of retained placenta. The six ITKs for the retained placenta condition were subjected to validation test through the QuIK (Quantification of Indigenous Technical Knowledge) method. All the ITKs were found to be effective against retained placenta. However, these were perceived to be comparatively less effective than the Modern Veterinary Drug (MVD) in numbers of animals cured and quickness of healing. The indigenous practices were perceived better than MVD in respect of their availability, lesser side effects and lower cost.
Evaluation of growth performance and mineral accumulation of broilers fed chromium
A total of 360 day old straight run Vencobb broiler chicks were randomly allocated to six treatment groups with three replicates of 20 birds in each to study and compare the effect of chromium from three sources(inorganic, organic or nano) at two different dosage level on performance, and tissue accumulation in broiler chickens. The trial lasted for 6 weeks. The control group (T1) was given with the standard broiler diet while the other groups were supplemented with chromium(Cr) at 200 µg/kg (inorganic chromiumchloride-T2, organic chromiumpropionate (CrProp)-T3, chromiumpicolinate (CrPic)-T4 and nanochromium(nanoCr-T6) and 100 µg/kg (nanoCr-T5) diets. The results showed significantly increased body weight gain, decreased feed consumption and improved feed efficiency in nanoCr followed by organic and inorganic Cr supplemented groups. The Cr content in the plasma and liver was significantly increased by nanoCr followed by organic CrPic (200 µg/kg) supplemented groups while Cr in thigh muscle was increased by both nanoCr and organic CrPic (200 µg/kg) and that of breast muscle was increased by all Cr fed groups. It can be suggested that the addition of chromium to soya bean and maize diets improves the performance of broilers with increased plasma, liver and muscle tissue accumulation.
Methodology of Identification and Characterization for Sustainable Development of Small and Marginal Farmers in Jammu
The present study was conducted to characterize the status of different farming systems and their impacts on the livelihood of farmers in Jammu. A total of 120 farmers were selected for multistage strategies, out of these 40 organics, 40 inorganic, and 40 integrated farming systems were selected from the study area based on different interventions. Descriptive statistics were derived and calculated for analyzing the socio-economic data. Propensity score matching (PSM) was applied with kernel matching and radius matching methods to assess the impact of organic, inorganic, and integrated farming on farmers’ employment creation and income generation. The results of the baseline survey revealed that out of 120 sample farmers were categorized as follows: landless (15%), marginal (18%) small (44%), medium (14%,) and large (9%), respectively. The highest employment duration for the male gender was 152.5man days/year from farming systems like Crop+ Livestock+ Poultry + Horticulture (C+L+P+H) under integrated farms and for organic and inorganic these values hoisted at 125.5 and 104.5man days /year. The highest returns were obtained from the pulse-mustard-wheat cropping system with a B: C ratio of 2.03 followed by the rice-maize-vegetable cropping system with a benefit: cost ratio of 1.97. The average calorie intake of food secure per household was 2910 kcal, 2793 kcal, and 2854 kcal for organic, inorganic, and integrated farming systems, respectively. To assess the livelihood pattern through the asset pentagon approach, net-worthy improvement was found based on different capitals of farm households practicing in organic, inorganic, and integrated farming. Based on different problems a constraint-facing index (CFI) was calculated to suggest policy recommendations.
