The ‘Vehicular Ad hoc Network’ (VANET) has appeared as a feasible field of research. The VANETs performance is widely influenced by the routing protocol (RP). Hence, to make the RPs vigorous to recurrent communication disruptions and also aware of unstable traffic conditions, new routing techniques need to be integrated. Those protocols are termed traffic aware protocols (TAP) because their routing decisions are affected by the traffic status. Here, a TAP is designed for an urban environment. Initially, the traffic parameters for instance, traffic density (TD) and average speed are determined. The prediction of the TD besides the vehicle speed is done by employing the ‘Weighted Moving Average’ (WMA) technique. The optimization of the traffic-aware routing protocol (TARP) is done using the Hybrid ‘Worm Swarm Optimization’ (GWSO) algorithm. Moreover, this algorithm is a merge of the GWSO and the ‘Genetic Algorithm’. Finally, the performance was evaluated by determining a few metrics and then a comparative scrutiny was done.
A field experiment was conducted at Agronomy Main Research Farm, Department of Agronomy, Orissa University of Agriculture and Technology, Bhubaneswar, Odisha, India during kharif season of 2016 and 2017 on ‘Impact of Crop Establishment Methods and Weed Management Practices on Weed Dynamics and yield of rice”. The field experiment was laid out in a split plot design with three replications by taking 24 treatment combinations with four crop establishment methods in the main plot, viz., M1: direct seeded rice (DSR), M2: wet seeded rice (WSR), M3: non-puddled transplanted rice (NPTR), M4: puddled transplanted rice (PTR) and six weed management practices in the sub-plot, viz., W1: weedy check, W2: Bensulfuron methyl 0.6% + Pretilachlor 6% ((pre emergence(PE)) 0.660 kg ha-1 + hand weeding (HW) at 30 DAS/T, W3: Bensulfuron methyl 0.6% + Pretilachlor 6% (PE) 0.495kgha-1 + HW at 30 days after sowing/transplanting (DAS/T), W4: Bensulfuron methyl 0.6% + Pretilachlor 6% (PE) 0.495kgha-1 + Bispyribac-Sodium (post emergence (POE)) 0.025 kg ha-1 at 15 DAS/T, W5: Cono weeding (CW) at 15 DAS/T + hand weeding 30 DAS/T, W6: brown manuring/ green manuring. Puddled transplanted rice recorded highest yield with lowest weed incidence and direct seeded rice recorded lowest yield with highest weed incidence among different establishment methods. While, application of Bensulfuron methyl 0.6% + Pretilachlor 6% (PE) @0.660 kg ha-1 +HW at 30DAS/T recorded highest yield with lowest weed incidence.
The National Watershed Development Projects for Rainfed Areas (NWDPRA), with a broad objective of resource management for improving agricultural productivity and production to biomass on a sustainable basis and restoring ecological plans in rainfed areas, was launched in 1990–1991 in two Union Territories and 25 States of India. However, it has been put into practice in the India state of Odisha since 2001 with the primary goal of enhancing the quality of life of underprivileged groups, notably tribal women, by fostering chances that will help them raise their standard of living. The current study, which was conducted in the Badasahi and Saraskana blocks of Mayurbhanj as well as the Champua and Jhumpura blocks of Keonjhar district in the Indian state of Odisha, has been designed to analyze socioeconomic characteristics, the degree of involvement, changes in knowledge, skill, attitude, and developments from the farm women for the effective implementation of watershed programmes. The sample size for the study was 192 farm women from 24 watersheds. In order to analyze the data and determine the outcome, statistical tools like percentage, mean score, standard deviation, co-efficient of variation, correlation coefficient, test of significance, critical ratio test, multiple regression, stepwise regression, and path analysis were used. According to the study, the majority of respondents had a relatively middle socioeconomic background. In contrast to harvesting and post-harvest management, which had better associations and significantly influenced development, variable education, extension contact, social participation, possession of agricultural implements, change in knowledge of field crops, and income-generating activities. It had a negative attitude toward institutional arrangement, funding pattern, community organization, planning, programme implementation, and formulation.
Paddy sown with conventional puddled transplanting method is being considered as serious issue nowadays in view of climate change as it is more water & labour intensive technology. DSR is a feasible alternative to solve above issues so the present study was conducted in Ambala and Kurukshetra districts of Haryana, aiming at examining the preference of Direct Seeding (DSR) over Trans-Planting/Puddled Rice (TPR) and constraints experienced by farmers in its adoption during Lockdown for COVID-19 control in 2020. Empirical data was collected in 2020 & 2021, personally from 160 respondents, consisting 20 farmers from eight villages through a precisely & designed interview schedule and analyzed using standard methodology. According results majority of the respondents (78.75%) had fallen belonged to Low to Medium and 21.25 percent farmers had found to High category of overall adoption level of DSR technology during paddy season i.e. 2020 kharif, Whereas it was found for the Kharif 2021, most of farmers (88.12%) had a Low to Medium and only 11.88 percent respondents belonged to High category of overall adoption level of DSR that means the adoption of DSR among farmers, in 2020 was a little higher than of 2021 in other words farmers preferred DSR over TPR as they had been faced labour scarcity during COVID-19 pandemic in 2020, which derived them to go for DSR adoption in some extent, rather than TPR and constraint of Non availability of DSR machine at the time of sowing faced the most in lockdown as machine requirement had increased among farmers due to low availability of labour for transplanting during lockdown, Weed infestation, Insufficient knowledge of DSR cultivation, The occurrence of rain before germination were also serious obstacles in adopting DSR.
Twenty four varieties of chrysanthemum were screened for leaf longevity based on phenotypic and physiological traits. The experiments were laid out in Completely Randomized Design (CRD) consisting of 24 varieties with 3 replications. Out of 24 varieties minimum leaf longevity was recorded in cv. Pusa Shwet, while maximum in cv. Pusa Guldasta. Earliest leaf browning was recorded in cv. Raja whereas cv. Tata Century took maximum days for leaf browning. Maximum vase life was recorded in cv. Tata Century while minimum in cv. Yellow Reflex. Chlorophyll content and relative water content found to decrease with increase in storage after harvest. Maximum total chlorophyll and chlorophyll a content was recorded in cv. Pusa Guldasta while minimum in Pusa Shwet. However, Maximum chlorophyll b content was recorded cv. Jaya and minimum in cv. Raja. Maximum relative water content was recorded in cv. Tata Century while minimum in cv. Pusa Shwet. Thus among 24 varieties selected; two varieties viz., Tata Century and Pusa Guldasta performed best in terms of leaf longevity, vase life, chlorophyll content and relative water content.
