Coffee cultivation in agro forestry system in the non-traditional Bastar zone of Chhattisgarh

Paper ID- AMA-25-10-2021-10812

The present investigation was undertaken in the Darbha block of Bastar region in Chhattisgarh. The data's are based on three year old coffee plantations planted in 2017-2018. The results revealed the maximum under storied plant height in Chandragiri Dwarf (1.86 m) which was at par with CxR (1.82 m) and San Ramon (1.71 m) whereas CxR recorded the maximum diameter at breast height (3.72) and number of branches plant-1 (45.15). With regard to the upper storied crop agro ecosystem, silver oak recorded the maximum plant height (7.84 m) in S-8 intercropped line while the diameter at breast height in silver oak was the highest in CxR (5.58 m) intercropped lines which was at par with the intercropped lines of S-8 (5.40 m). Chandragiri Dwarf recorded the maximum under storied biomass from above ground biomass (118.41 Mg ha–1) and below ground biomass (29.60 Mg ha–1) as well as carbon sequestration recording 217.28 and 54.32 Mg ha-1 respectively from above and below ground zone. However the total carbon stock including the under storied as well as upper storied agro ecosystem was the highest in S-8 (230.43 and 57.61 Mg ha-1 respectively) followed by CxR (209.96 and 52.49 Mg ha-1 respectively).

Time Optimization when External Grinding Grey Cast Iron

Paper ID- AMA-25-10-2021-10811

This paper presents an optimization study to determine the optimum replaced grinding wheel diameter to achieve the minimum machining time when external grinding grey cast iron. In this study, several main input process parameters including the initial grinding wheel diameter, the grinding wheel width, radial grinding wheel wear per dress, the total depth of dressing cut, and the wheel life were investigated. The influence of these parameters on the optimum replaced grinding wheel diameter was analyzed by using Minitab software. In addition, a regression formula to determine the optimum replaced grinding wheel diameter when grinding grey cast iron has been introduced.

Lightweight design of a chassis frame for a rice combine harvester

Paper ID- AMA-23-10-2021-10810

Taking a crawler joint harvester chassis frame as the research object, a 3D frame model was built, importing the model into Ansys Workbench to establish a finite element model, and conducting modal analysis and taking the wall thickness of the frame as the design variable, the frame thickness as the research variable, frame multi-objective optimization was carried out. Under the premise of meeting the performance parameters, calculate the best frame wall thickness, improve the accuracy and efficiency of optimization, genetic algorithm was used to optimize multi-objective optimization of beam thickness. The results showed that under the verification of the stiffness, strength and modal characteristics of the chassis frame, the high-strength steel composite frame reduces the 36.1Kg, weight reduction effect by 11.1% compared with the original frame quality, and the lightweight effect is significant.

Effect of Input Parameters on Electrode Wear Rate when PMEDM 90CrSi Steel with Graphite Electrodes

Paper ID- AMA-22-10-2021-10809

This paper introduces the results of research on optimization of powder mixture electrical discharge machining (PMEDM) process when processing cylindrically shaped parts with graphite electrodes. In this study, 90CrSi tool steel was chosen as the workpiece material. Besides, the electrode wear rate (EWR) is selected as the objective function of the optimization problem. To solve this problem, an experiment with the Taguchi design was performed. Also, the Minitab R19 software was used to design experiments and analyze the results. The influence of the input process parameters, including the powder concentration, the pulse on time, the pulse off time, the servo current, and the servo voltage on EWR was investigated. In addition, optimal process parameters for minimum EWR were given.

Rooting and Adaptation of Solanum tuberosum L. under Ex Vitro Conditions after Exposure to Different Sucrose Concentrations in the In Vitro Nutrient Medium

Paper ID- AMA-21-10-2021-10808

The composition of nutrient media intended for the formation of morphogenic callus in tissue culture is a key element of the intermediate link in the production of plants in vitro. The six potato varieties of the Ukrainian breeding of different ripeness groups early-ripening, mediumearly, medium-ripening were used as the research object. Fragments of the apical meristem of plant organs were selected for the introduction of in vitro in the culture. Parts of stems with axillary buds were used to produce callus tissue. The Murashige and Skoog media (Murashige and Skoog, 1962) with sucrose content modifications of 30 and 60% were used to induce callus genesis and growth of the resulting callus. The control version of the medium contained 10% sucrose. The resulting material was planted in the open ground on the experimental plots of Sumy National Agrarian University. The results of the studies indicate a generally positive, but uneven effect on the rooting nature of test tube plants of the varieties used. Individual variants of potato cultivars of different ripeness groups grown on a medium of both 10 and 30% and 60% sucrose content are considered to be promising for further reproduction and use in the breeding process.
