Evaluation of disease reaction, yield attributes and yield of chickpea germplasm

Paper ID- AMA-24-04-2023-12214

Chickpea is an important Rabi food legume grown throughout the world. India is the largest producer and contributes 2/3rd of total production of global chickpea. Productivity of chickpea in India is lesser than some other countries due to various factors. Cultivation of chickpea crop is adversely affected by both biotic and abiotic stresses. Among biotic stresses collar rot is an important limiting factor for the production of chickpea. Collar rot incited by Sclerotium rolfsii is an economical disease of chickpea and causes 10-30 per cent yield loss annually. The disease appears moderate form every year in chickpea growing areas. It causes heavy losses in chickpea sown after harvesting of rice having stubbles in cultivated fields. Keeping in view of the serious and economical losses caused by the pathogen, the present study on assessment and identification of germplasm for resistance source and better yield performing genotypes have been conducted during Rabi 2021-22 at Bihar Agricultural University, Sabour, Bhagalpur, India. In the present investigation, two hundred fifty three germplasm were evaluated for their yield and resistance against collar rot under natural sick plot field conditions. Due to continuous growing of breeding material in same field for the last many years, it has high inoculum load. Among evaluated germplasm none of them were found resistant against collar rot disease. However, two hundred fourteen germplasm lines exhibited moderately resistant, twenty two moderately susceptible, eleven susceptible and six genotypes identified as highly susceptible. All germplasm were also assessed for their yield and yield attributing traits in which ICCV 94954 (2937.50 kg/ha), GL-15209 (2845.84 kg/ha), GL-15131(266.66 kg/ha), CSJ 1065 (2645.84 kg/ha), IPC 2011-141 (2595.84 kg/ha), GNG2475 (2591.66 kg/ha) and RSGD 1174 (2562.50 kg/ha) showed moderately resistant reaction as well as better yield performing genotypes which may be utilized for breeding programme for the development promising entries against collar rot disease.

Determining mower’s double cutter-bar basic parameters

Paper ID- AMA-24-04-2023-12213

In the field of agriculture, machines are very important tools to increase the productivity of good quality products. Therefore, it is necessary to develop such technological machines, constantly updating the working mechanism. The mower is one of those machines that cutting mechanism is a very important working device, which must been continuously improved. Therefore, a new mower’s double cutter-bar is designing to improve the technological and mechanical performance of the mower. This paper concerns basic parameters of mower’s double cutter-bar mechanism. A kinematic study concerning the double cutter bar mechanism using the method of closed contours, therefore analytical equations are developed, describing the trajectory of the knives, the speed and the acceleration, while also determining the necessary driving power as well as the device power supply and pinch, thus justifying the basic parameters of this mechanism. To validate these mathematical expressions experimentally, a prototype of this mechanism is made within the Kazakh Institute for Scientific Research on Mechanization and Electrification of Agriculture allowing to adjust and improve several design and technology parameters. The correctness of the theoretical premises is confirmed by testing the developed prototype mechanism in agricultural fields.

Acute Toxicity Evaluation of Aqueous Extract from Hertia cheirifolia in Swiss Albino Mice

Paper ID- AMA-24-04-2023-12212

Hertia cheirifolia L. is a medicinal plant belonging to Asteraceae family. It is traditionally used to treat gastrointestinal ailments, infections, and spasms. The aim of this study is to evaluate the oral acute toxicity of aqueous extract from Hertia cheirifolia on female Albino wistar mice. Animals were divided into three groups, the first group received distilled water and was used as control; Mice of the second and third groups received the plant extract at doses of 2g/kg and 5g/kg body weight of animals, respectively. The mice were monitored for 14 days for their general behavior, adverse effects and mortality. The results showed that no death or toxic signs were observed, no changes were seen in food consumption, body weight and organ weight in the treated animals compared to the controls. However, an increase in AST and ALT levels was recorded in mice treated with the extract.

Research on Path Tracking of Intelligent Tractor Based on Variable Universe Fuzzy Adaptive Model Predictive Control

Paper ID- AMA-21-04-2023-12210

Since the operating speed and tracking path of intelligent tractors are constantly changing, the model predictive control based on fixed parameters cannot achieve ideal results. This paper proposes a variable universe fuzzy adaptive weight MPC tracking control algorithm considering automatic steering system. Firstly, the tractor dynamics model, tire mechanics model and automatic steering system model are constructed. Secondly, a linear tracking error model is constructed based on the tractor dynamics model and the automatic steering system model. Again, a path-following control algorithm based on MPC is designed. Then, in order to improve the control precision and self-adaptability of MPC, a fuzzy self-adaptive weight regulator with variable universe is designed. Finally, the co-simulation of pear-shaped and semi-circular operating conditions is designed. The simulation results show that the model predictive controller considering the automatic steering system solves the problem of excessive tracking error caused by the delay, overshoot and oscillation of the automatic steering system in the tracking process; the variable domain fuzzy adaptive weight regulator realizes the adaptive weight Adjustment, so that the tracking control effect can meet the operation requirements under different operating speeds, and the speed robustness of the tracking control is improved.

Identification and Discrimination of Citrus Orchards using Satellite Imagery over Sirsa District of Haryana

Paper ID- AMA-21-04-2023-12208

In the recent era mapping of particular crop becomes an interdisciplinary nature in which agricultural and geo-informatics sectors comes together and monitoring the particular crop. In order to analyze the potential of remote sensing based technology for the mapping of crops in horticulture field, the present study was initiated for the discrimination and classification of citrus orchards with the help of multi-temporal satellite data. To achieve the objectives of the study Multi-date Sentinel-2 images covering the study area were acquired. The major challenge was to discriminate the Citrus plantation from agriculture and other plantation cover. After analyzing the multi-temporal data the optimum dates depicting the clear differentiation between the citrus plantation and associated other agricultural and horticultural crops were selected. The NDVI of the selected optimum multi-date data was layer stacked. The supervised classification based approach wa performed with the help of ground truth points for the identification and discrimination of Citrus orchards. This study provides the potential of using high-resolution NDVI imagery of Sentinel-2 for the identification, discrimination and demarcation of citrus orchards.
