Flower craft is one of the most flourish and dynamic enterprises in today's world. Tinting or artificial colouring of tuberose may be a potential value addition venture. Tuberose (Polianthes tuberosa L.) is a popular cut flower having white coloured fragrant blooms. Postharvest losses in many cut are estimated to be as high as 40% in the absence of floral preservatives. Blockage of vascular bundles due to microorganism proliferation is one of the reasons for cut flower postharvest losses. Therefore in this experiment effect of different biocides on kind and proliferation of microbes in vase solution of tinted tuberose were studied. In present experiment five different food dyes were used as tinting agent likes Blue, Apple green, Lemon yellow, Orange red and Rose pink at a concentration of 1%. Therefore an inspection was carried out to study the effect of different biocides (Calcium hypochlorite solution of 750 ppm, Sodium hypochlorite solution of 750 ppm, Benzyl adenine 450 ppm and Naphthalene acetic acid 250 ppm) on value addition and vase-life of tinted tuberose cv. Prajwal. In which flowers remained maximum fresh with higher vase-life in Lemon yellow followed by Rose pink and Apple green. Results suggest that among all chemicals Calcium hypochlorite (750 ppm) was best followed by Sodium hypochlorite (750 ppm), Benzyl adenine (450 ppm) and Naphthalene acetic acid (250 ppm).

Aims & Objective: The fast depletion of fossil fuels and the growing awareness of environmental protection has become a concerning topic. Because of this fact, the researchers are working for a long time to generate electrical energy sources due to the intermittent nature of unconventional energy sources such as solar, wind geothermal, tidal, and biomass as a sustainable, cost-effective, and environmentally friendly alternative for conventional energy sources. These systems are interconnected and full-fill demands as well as energy storage, which subsequently formed a complex hybrid renewable energy system. Hence, forecasting of energy generation, sizing of equipment is essential for the economic feasibility of a complex hybrid system. Also necessary for the design analysis. Methodology: In this research article, the proposed Functional Link Convolutional Neural Network (FLCNN) is applied to forecast the energy generation from the hybrid solar and wind energy system. Also, the Jaya algorithm has been applied to find the optimal sizing of the solar and wind based hybrid renewable energy system. Results & Discussion: The proposed method is simple in design and implementation, and it also reduces computational complexity and time. The proposed FLCNN technique has been compared with various other Machine Learning (ML) methodology, such as Convolutional Neural Network (CNN), Random Forest (RF), and Xg-Boost. In sizing, Jaya is compared with other heuristic techniques such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Cat Swarm Optimization (CSO). Conclusion: The proposed FLCNN and Jaya optimization techniques successfully applied for tasks like energy forecasting and sizing of the renewable energy system.

Flower craft is one of the most flourish and dynamic enterprises in today's world. In this craft, value addition and postharvest handling methods of cut flowers is a captivating and trilling craft gaining importance now-a-days. Tuberose (Polianthes tuberosa L.) is a popular cut flower having white coloured fragrant blooms. Tinting or artificial colouring of tuberose may be a potential value addition venture. Tinting is an important value addition technique in flower crops where colour pigments are absent or light or dull. Colouring inflorescences with edible dyes enhance the visual appeal of these flowers, increase their economic value and aesthetic beautification. Studies were carried out Tuberose (Polianthes tuberosa L.) cv. Prajwal to evaluate the ability of flower to obtain and retain different colour shades for the elimination of limited acceptability in market which is mainly due to white colour. Six different food dyes were used as tinting agent in the experiment all in powder form viz, Blue, Apple Green, Tomato red, Orange red, Lemon yellow and Rose pink at a concentration of 1%, 2% and 3% for all. The darkest shades of colours were obtained in 3% concentration while lightest shades in 1%. The maximum vase-life was found in tuberose spikes which were treated with 1% Lemon yellow whereas minimum vase life recorded for Tomato red food dye (3%). The highest Benefit: Cost ratio was obtained for Lemon yellow food dye (1.83) at concentration of 1%. Blue food dye also obtained better net realization (1.69) at 1 % concentration.Value addition from flowers is including extraction of essential oils, tinting of flowers, flower drying, and preparation of veni, corsage and bountonniere. It is widely grown as specimen for exhibition, cut flowers, artistic garlands, floral ornaments, bouquets and buttonholes. The long flower spikes are excellent as cut flowers for table decoration. The value addition technique like colouring of white flowers can add value up to 5 to 10 times (Mekala et al., 2012). Tinting or artificial colouring of tuberose may be a potential value Abstract Article History
