No full textA study was conducted to standardize packaging technology for export of jasmine flowers. Experiments were laid out in FCRD in three replications, with 12 chemical treatments, and packing with unit packing boxes and thermocol boxes under gel-ice cold condition. Effects of various chemical treatments and their interaction with packaging were studied and observations were recorded on visual quality (freshness index, flower-opening index, colour retention index and fragrance score) of flowers and physiological parameters associated with post harvest quality of flowers. Export suitability of the package was also studied and Cost:Benefit ratio (CBR) worked out. Chemical treatment of flowers with 4% boric acid, packing in aluminum-foil lined boxes and further packaging in thermocol boxes under gel-ice cold condition was found to be significantly superior to Control, and recorded a shelf life of 42.88h. This package also recorded maximum freshness index (70 to 90%), minimum flower-opening index (10.5 to 50%) and maximum colour retention index (77.77 to 88.88%) of flowers. CBR was 1:2.5

No full textA Review and Analysis of GAN-Based Super-Resolution Approaches for INSAT 3D/3DR Satellite Imagery using Artificial Intelligence
No full text627-638The Indian National Satellite System (INSAT)-3D/3DR is a geostationary satellite that is used for meteorological
applications in the Indian region. Geostationary satellites have significant spatial coverage and good temporal resolution that
help to monitor the evolution and propagation of meteorological systems. Meteorologists use satellite images to observe the
locations of severe weather and understand the physical processes involved in the system. Image Super-Resolution (SR)
aims to convert low-resolution images into high-resolution images while maintaining image quality. The SR techniques will
improve the visualization of convective systems and tropical cyclones, facilitating accurate location-based warnings. This
paper presents a comparative comparison of computer models for converting Low-Resolution (LR)(INSAT)-3D/3DR
images into super-resolution images. This study also discusses and investigates the various Generative Adversarial Network
(GAN)-based models, including the Super Resolution Generative Adversarial Network (SRGAN), Enhanced Super
Resolution Generative Adversarial Network (ESRGAN), and Real Enhanced Super Resolution Generative Adversarial
Network (Real-ESRGAN). The findings are compared to established approaches such as Bicubic Interpolation and Super-
Resolution Convolution Neural Network (SRCNN). This study demonstrates that Real-ESRGAN performs better on weather
satellite images than other cutting-edge approaches
Soil test based nourishment to enhance yield attributes, nutrient-uptake, pigment and economics of beetroot grown in Western Ghats of Tamil Nadu
No full textBeetroot (Beta vulgaris L.) is a widely cultivated root vegetable globally known for its significant health benefits. This study was conducted on a farmer’s field in the Nilgiris district of Tamil Nadu\u27s Western Ghats, using the improvedcrystal hybrid beetroot, to evaluate the effects of varying dosages of nitrogen (N), phosphorus (P), potassium (K) and integrated nutrient management systems on yield attributes, nutrient uptake, pigment content and costeffectiveness. The experimental trials were carried out in Kadanad village during the winter of 2024 and in Emerald village during the summer of 2024. The treatments included untreated nutrient controls, a general fertilizerrecommended dose (GFRD), GFRD combined with farm yard manure (FYM), soil test crop response (STCR) inorganic-based nutrient doses targeting yields of 350, 400 and 450 q ha-1, STCR integrated-based nutrient doses with the same yield targets and the farmer’s standard fertilizer application. The findings showed that the treatment with 1.80 N + 2.33 P2O5 + 1.16 K2O q ha-1 combined with FYM @125 q ha-1 (T3) achieved the largest root diameter (8.76 cm), root perimeter (28.67 cm), total root length (20.40 cm), edible root length (8.1 cm), root fresh weight (264.51g per plant), root dry weight (23.53g per plant), root yield (442.10 q ha-1), nutrient uptake of N (181.65 kg ha-1), P (35.26 kg ha-1), K (195.98 kg ha-1) and pigment content (total betalain 138.02 mg 100g-1 FW, betacyanins 93.34 mg 100g-1 FW, betaxanthins 44.68 mg 100g-1 FW). This treatment also achieved the highest gross revenue (1,326,300 Rs), net income (1,100,300 Rs) and benefit-cost ratio (4.87:1)
Physico-chemical properties of spray dried anthocyanin extract from hibiscus flowers (Hibiscus rosasinensis L.) as food colourant
No full textFlowers are a rich source of bio-pigments like carotenoids, anthocyanins and betalains. Among these, anthocyanins are the most abundant pigments and Hibiscus flowers are one source of anthocyanin pigments. The major drawback in using hibiscus anthocyanins as a food colourant is their stability. Hence, to enhance stability, microencapsulation of aqueous extract of hibiscus petals was attempted with maltodextrin encapsulation at different TSS levels and temperatures and the physico-chemical and functional properties of spray dried hibiscus powder were assessed. Microencapsulation of anthocyanin extract with maltodextrin at 15° brix and 180 °C resulted in the highest dried powder recovery (17.85%), anthocyanin content (64.81 c3g eq.mg/L) and water solubility (99.58%). Physical properties like bulk density (0.593 g/m3) and tapped density (0.695 g/m3), was significantly higher in spray dried hibiscus powder obtained with maltodextrin 20 °brix at 170 °C. Based on Hausner’s ratio (1.16), Carr index (14.04) and hygroscopicity (17.85%), hibiscus spray dried powder exhibited good flowability when dried with maltodextrin 15 °brix at 180 °C. Chromometer values of spray dried encapsulation with maltodextrin 15 °brix at 180 °C proved a deep red shade with more darkness (L*38.5) and (a* 23.50 and b* -0.67) when compared to other treatments. The spray dried powder also exhibited significant colour stability when used as food colourant in aonla juice, lemon juice, curd and butter cream. This study explored the potential of spray-dried anthocyanin extract from hibiscus flowers as a bio-colourant in the food industry
Unveiling genetic richness: Profiling broad bean diversity in the Nilgiri Hills through morphological, biochemical, and SSR markers
No full textThis study aimed to uncover the genetic relationship among broad bean genotypes to establish a high-yielding strain to elevate the status of this underutilized vegetable in the country. Twenty broad bean genotypes were assessed using randomized block design to reveal their genetic connections derived from twelve morphological factors and seven biochemical attributes. In addition, SSR primers were used to examine the molecular differences. The multifaceted data obtained were combined to evaluate genetic distinctions among these genotypes. The genetic analysis revealed that pod production per plant exhibited superior values of both phenotypic and genotypic coefficient of variation. Association analysis of green pod yield featured a strong positive correlation with seed yield, carbohydrate content, pod count per plant and 100 seed mass. The most notable positive direct influence on green pod yield was due to 100 seed weight. Choosing traits with a strong correlation with pod yield, along with moderate to high levels of phenotypic coefficient of variation (PCV), genotypic coefficient of variance (GCV), heritability and genetic progress would boost the effectiveness of the broad bean improvement program. The cluster analysis sorted the 20 genotypes into six groups, highlighting the considerable variation within each group. Among the SSR primers screened, the peak PIC score of 0.660 was noticed for the primer GBSSR-VF-172. The dendrogram constructed based on SSR markers resulted in two major clusters, illustrating the genetic affiliations and diversity within the genetic lines. This multidimensional characterization highlighted significant genetic disparities among broad bean genotypes, facilitating the selection of superior genotypes to develop high-yielding cultivars
