An analytical study of the ride performance of an agricultural truck with two types of hydro-pneumatic suspension struts

Paper ID- AMA-05-08-2021-10520

This proposal study is to analyze the performance of two different types of hydro-pneumatic suspension struts for an agricultural truck. The nonlinear dynamical models of two different types of hydro-pneumatic suspension struts with two oil chambers and one gas chamber (Model 1) and with three oil chambers and one gas chamber (Model 2) are set up to determine their nonlinear forces in the vertical direction. A quarter–vehicle mathematical model of an agricultural truck is set up for the analysis of the nonlinear forces of two proposed Models under random road surface excitation which is implemented in MATLAB/Simulink platform. The obtained results indicate that the value of the root mean square (RMS) of the vertical acceleration response of vehicle body with Model 2 reduce by 5.11% in comparison with Model 1 when vehicle moves on ISO class D road surface at vehicle speed of 40 km/h and full load. Finally, both two hydro-pneumatic suspension struts are verified their ride comfort performances under various vehicle operating conditions and the obtained results also indicate that the performance with Model 2 significantly improved vehicle ride comfort in comparison with Model 1.

Simulation analysis of hydraulic brake drive for an earth moving equipment using elastic model

Paper ID- AMA-05-08-2021-10519

Nonlinear properties of fluids and hydraulic brake drive system (HBDs) components have a great effect on the braking performance. The purpose of this study is to consider their effects on the braking performance. Firstly, the theoretical basis of the elastic model of the hydraulic brake system is proposed based on the nonlinear properties of the fluids and the system compositions. And then a nonlinear mathematical model of HBDs of full power hydraulic brake system with the wet multi disc brakes for an earth- moving equipment is set up for simulation and analysis which uses Matlab/Simulink software to simulate and analyze with the set of parameters of fluid and HBDs. The simulation results show that the system responses change in accordance with the elastic properties of the fluid in the brake drive system. Finally, the fluid properties and structural parameters of HBDs are investigated their effects on the system response time and the pressure fluctuations. The obtained results show that the survey parameters of fluid and HBDs have a significant effect on the system response times and the pressure fluctuations.

Multivariate analysis of Oat (Avena sativa L.) genotypes under multi-cut regimes to delineate genetic variation

Paper ID- AMA-05-08-2021-10518

In the present investigation 92 Avena genotypes were evaluated for multi-cut nature in randomized block design with three replications at the Research Farm area of forage Section, Department of Genetics and Plant Breeding, CCS HAU, Hisar during rabi season. Highly significant differences observed by analysis of variance showed presence of high amount of variability for single cut and multi-cut. Correlation analysis indicated positive and significant correlations of green fodder yield with dry matter yield, plant height and number of tillers. Genotypes collected from different geographical areas had a role in the clustering pattern and cluster with highest inter-cluster distances were considered for hybridization as potential parents for obtaining high heterotic response. In single cut, the principal component analysis found three components with eigen values more than one and altogether explained 67.95% of the total accumulated variability. The first principal component explained 26.24% followed by second (21.84%) and third (19.87%). of the total variance while principal factor-3 (PF-3) showed regarded as fodder yield factors. In second cut, seven principal components had eigen values more than one and altogether explained 73.34% of the total accumulated variability. The first principal component explained 15.31 % of the total variation, followed by second, third, fourth, fifth, sixth and seventh principal components explained 11.94, 11.79, 10.54, 10.40, 7.38 and 5.97 % of the total variance, respectively, while PF-2 and PF-4 regarded as fodder yield factors for second cut of multi-cut oat.

Sustainable management of brinjal shoot and fruit borer- a review

Paper ID- AMA-05-08-2021-10517

Brinjal, Solanum melongena Linnaeus belongs to family solanaceae also known Eggplant or Baingan and it is the most important widely grown vegetable both for raw and cooked purpose and attack by the major and serious pest known asbrinjal shoot and fruit borer [Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae)] which is responsible for causing up to 37-100% damage as well as quality and quantity loss in brinjal. In order to manage this problem, farmers still depends on the pesticides, but excessive use of pesticides has resulted residues in the food chain, phytotoxicity, pesticide resistance, pest resurgence, bioaccumulation and secondary pest outbreak, in addition to causing harmful effect on the environment and non-targeted beneficial organisms. Here, we reviewed the sustainable approaches to reduce the incidence of brinjal shoot andfruit borer toachieve sustainability in brinjalproduction technology through the implementation of integrated approaches. We found that following major points have been reported to reduce the survival and damage of shoot and fruit borer: (1) use of resistant varieties (2) implementing a number of cultural practices, such as sowing time,plant density, inter/mixed/relay crops (coriander, clustrebean fennel, chilly, redhuni, radish, mint, onion, clover, fenugreek, maizeand African marigold), avoid ratooning of crop, collection and destruction of dried shoot tips and damaged fruits, mechanical practices as barriers and installing bird perches(3) monitoringthrough the pheromone traps(4) spraying repellent made up of neem seed kernel (NSK). Hence, integration of all these approaches in a unified manner has exposed more good results for sustainable management of shoot and fruit borer. This review highlights examples of successful management approaches from the past studies that were implemented in experimental trials and farmers’ fields. We concluded that an integrated approach is the most effective for long-term sustainable and eco-friendly management programs for shoot and fruit borer.

Automatic seed cum fertilizer drill: Modification and performance evaluation for intercropping

Paper ID- AMA-05-08-2021-10516

The plastic roller cup feeding and weighing mechanism of the automatic sowing and fertilizing drill was improved for sowing between wheat chickpea (2: 1) and wheat mustard (3: 1). Weighing rollers were selected based on seed shape and size and the number of cells in the periphery. Different types of seed flow from each cup feeding roller were achieved by splitting the seed hopper in separate compartments. For the selection of weighing mechanism, calibration was performed among the seven available cup feeding weighing rollers with different combinations of seed box exposure lengths. The improved intercropping seed drill was calibrated in the laboratory for the required seed rate. The seed rate for wheat-chickpea intercropping is 75 kg / ha for wheat with 4 rollers and 25 kg / ha for chickpeas with 5 rollers on a seed box exposure scale of 7. I found out. The required seed rate for wheat-mustard cropping is 75 kg / ha for wheat with 4 rollers and 6 kg / ha for mustard with 7 rollers on the seed box exposure scale. It turned out. The effective field capacity of the sowing and fertilizing drill for chickpeas was 0.42 ha / h, and that for the mustard mustard intercropping was 0.47 ha / h. As a result of agricultural studies, wheat-chickpea (2: 1) intercropping was performed better than wheat-mustard (3: 1) intercropping and single crops.
