Saving energy in urban electrified train operation: Tracking optimal speed profile and backing regenerative braking energy to utility source by active rectifiers in traction substations

Paper ID- AMA-14-02-2022-11129

Significant traction energy consumption for electrified train operation has posed a great challenge to metro systems, so seeking energy saving solutions is necessary. Among many energy-efficient operation methods, this paper proposes two combined energy saving solutions: applying Pontryagin's maximum principle for determining the optimal speed profile with fixed trip time in an aim at operating trains to track this optimal speed profile, and using active rectifiers replaces diode rectifiers in traction substations to recuperate regenerative braking energy as the electric trains track the optimal speed profile. Designing control for active rectifiers includes three control loops: the current control loop with sliding mode control, the voltage control loop, and phase-locked loop (PLL) enable energy to flow bi-directionally. When trains operate in braking phases, active rectifiers back the regenerative braking energy to utility source. Simulation results with data collected from metro line Cat Linh-Ha Dong, Viet Nam conducted on Matlab/Simulink have evaluated saving energy for the whole metro line is up to 11.96% compared with consumption energy without using any saving energy solutions.

Impact of Salicylic acid on Biochemical composition in the fruits of Chilli (Capsicum annuum ) plants infected by Colletotrichum capsici (Sydow) Butler and Bisby

Paper ID- AMA-14-02-2022-11128

A field experiment was conducted at Horticulture Farm, SKNCOA, Jobner during 2015-16 and 2016-17. In this study, four different varieties viz., Pusa Jwala, Pusa Sadabahar, Pusa Dipti and Amulaya and three germplasms NU-7078, NP-46A and G-S of chilli were raised and transplanted in third week of July. Roots of chilli seedlings were dipped in hundred ppm solution of salicylic acid for 30 minute before transplanting and same concentration of salicylic acid was also sprayed on all varieties before flowering and per cent disease intensity was noted 90 days after sowing. The peroxidase activity was increased (28.95%) in infected plants of Pusa Sadabahar variety followed by Pusa Depti (20.59%), NP-46A (19.35%) and Amulya (18.18%) while it was minimum in Pusa Jwala (9.09%) as compared to healthy ones. Minimum disease intensity was recorded in Pusa Sadabahar (7.93%), as it was also resulted in maximum increase in peroxidase, while higher per cent disease intensity was recorded in Pusa Jwala (43.4%), which resulted in minimum increase in peroxidase. The polyphenol content was increased maximum (23.68%) in infected plants of Pusa Sadabahar variety followed by Amulya (20.69%), NP-46A (17.14%) and it was found minimum in Pusa Jwala (13.04%) as compared to healthy ones. Phenol content was increased maximum (23.53%) in infected plants of Pusa Sadabahar variety followed by NP-46A (20.45%), G-S (14.29%), NU-7078 (12.50%) and it was recorded minimum in Pusa Jwala (12.00%) as compared to healthy ones.

AnanasApp: Development of Fertilizer Calculator App for Pineapples

Paper ID- AMA-14-02-2022-11127

Pineapple is a fruit crop that constantly contribute to Malaysian agricultural GDP. Local pineapple industry is dominated by smallholders who are largely ill-equipped with ICT and modern technology. Sarawak as the nation’s second largest producer after Johor, has a substantial yet declining size of agriculture, forestry, and fishing workforce. Therefore, the state needs to capitalise on the increasingly accessible e-agriculture technology and high value crop such as MD2 pineapple (Ananas comosus var. MD2) to optimise yield and workforce. Efficient fertiliser management is essential to ensure sufficient and timely usage of fertiliser and related resources. Therefore, the AnanasApp mobile app is introduced as a tool to boost ICT application in local pineapple industry. AnanasApp that is built for the Android platform, is designed to assist with fertiliser management across all pineapple farming scales by identifying fertiliser requirements and costs per crop cycle, and guiding users to systematic fertilisation application. Equipped with important features such as simplicity, ease of use, user-friendliness, and high level of accessibility, the app can also attract younger pineapple growers and subsequently sustain the industry’s workforce.

Effect of Weed Management Practices on Weed Control Efficiency, Yield and Economics of Transplanted Rice in Typic Ustochrept Soil of Uttar Pradesh

Paper ID- AMA-13-02-2022-11125

A field experiment entitled “Effect of Weed Management Practices on weed control efficiency, yield and economics of transplanted rice was conducted during Kharif 2016 at Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U. P. (India) to find out the impact of different herbicides on weed flora, yield and economics of transplanted Rice (Oryza sativa L.). Among weed management practices sole application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE), Pyrazosulfuron (150 g a.i ha-1 PE), Butachlor (1.5 kg a.i ha-1) obtained selectivity towards broad leave weeds, whereas Oxidiargyl (100 g a.i ha-1 PE), Anilophos fb Bispyribac Sodium (400 g a.i ha-1 PE fb 25g a.i ha-1 POE), Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) performed selectivity towards narrow leave weeds, respectively. Similarly, Pyrazosulfuron fb Azimsulfuron (150 g a.i ha-1PE fb 30 g a.i ha-1 POE) recorded selectivity towards narrow leave weeds. Among weed management practices, this research finding indicates that the application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) proved to be the most effective in minimizing the total weed density (5.0,6.26 and 6.10 m-2), biomass of weed and enhancing the weed control efficiency (74.96 %), grain yield (46.20), net return (47902) and benefit ratio (2.27) which have the potential of being used as best combination of herbicides. Effective weed control practices could be used for the better production of transplanted rice in Typic Ustochrept soil of Uttar Pradesh.

Response of saline water irrigated mustard crop growth and yield under Cut-soiler PSSD salinity management

Paper ID- AMA-12-02-2022-11124

All aspects of plant growth and development are adversely affected by salinity stress. In arid and semi-arid regions, where rainfall is scanty, this detrimental effect on the crop productivity becomes more prominent. Salt stress induced crop losses are likely to increase substantially in the coming decades if appropriate corrective measures are not undertaken to tackle the intertwined menaces of salinity, water logging, and ions toxicities. This study clarifies the effectiveness of Cut-soiler (machine) constructed rice residue filled preferential shallow sub surface drainage (PSSD) to improve the drainage function and consequent effect on growth traits and yield of mustard during 2019-21. The study comprised of Cut-soiler drains as main plot treatment with two soil types (sub-plot) and three irrigation water salinity (4, 8, 12 dS m-1) as sub-sub plot treatment in a double replicated split-split experiment. Cut-soiler PSSD resulted in higher drainage outflow of water and salts with applied irrigation and rainfall events and reduced soil salinity by ~50.36 % without any extra salt loading even with the application of 12 dS m-1 salinity water irrigation. Such reduction in soil ECe, due to Cut-soiler constructed PSSD, led to significant improvement in plant height, number of leaves, branches and plants, leaf weight ratio, leaf area duration, specific leaf area, specific leaf weight, absolute growth rate and dry matter efficiency. These positive changes consequently enhanced mustard biological yield (18.08 %) and dry matter efficiency. All together it was observed that Cut-soiler PSSD effectively reduced the soil salinity even under the application of saline water (upto 12 dS m-1) irrigation.
