Abstract To simulate the bending behaviour of paddy straw at varied moisture contents after crop harvesting, we created a flexible specimen model based on Hertz–Mindlin with parallel contact bonding using discrete element (DEM) approach. The research presented in this study aims to investigate new approach called Definitive Screening Design (DSD) for parameterizing and screening most significant parameters DEM model. This investigation will specifically focus three-point test as means...

Cumin (Cuminum cyminum L.) is an important seed spice crop, having good medicinal properties and grown predominately in arid semi-arid region of the world. India leading country with share 70% world production cumin. Two states (Rajasthan Gujarat) cover nearly 80% total area under cumin cultivation. The current scenario status area, productivity has been reviewed to identify various factors affecting productivity. Apart from these major constraints related climate, soil, agronomical, crop...

Abstract The geometric features and operational parameters of rotary blades on tillers significantly impact their performance characteristics. sweepback angle is a feature the 'L'-shaped blade that has remained unexplored in previous studies. This study aimed to analyze effect geometrical dynamics blade. investigation was conducted using discrete element method (DEM) further validated through experiments soil bin. simulation experiment by dividing particle bed into horizontal zones....

A portable MSTD (mini solar tunnel dryer) was developed and evaluated in terms of drying rate, MR (moisture ratio) efficiency for pomegranate seeds. The characteristic curves were also determined OSD (open sun drying). In order to study the behaviour seeds MSTD, seven different models fitted. best prediction model estimate kinetics as criteria evaluating goodness-of-fit based on R2, SSE RMSE. Approximation Diffusion adequate describe with R2 value 0.99189 0.9943, respectively. 7% more...

Abstract Plant phenotyping is the science to quantify quality, photosynthesis, development, growth, and biomass productivity of different crop plants. In past, plant employed methods such as grid count regression models. However, method proved be labor‐intensive time‐consuming, while model lacked accuracy in calculating leaf area. To address these challenges, a portable automatic platform was developed for precise ground‐based imaging field plots. This consisted frame, an RGB camera, stepper...

Tractor wheel slip affects the traction of a tractor, fuel efficiency and tyres adversely, along with compaction soil. operators cannot sense unless it continues for some significant time. In present study, low-cost measuring device an indicator were developed at ICAR-IARI, New Delhi (2018) installed on tractor dashboard operator’s information. It warns operator about both by visual auditory signals to adjust driving accordingly. this four different sensors (Inductive proximity sensor, IR...

Higher risks involved in excess fertilizer application require precise placement of adequate amount the root zone crop. The drawbacks current techniques (band placement, pellet application, and ring basin method) include over-fertilization, soil acidity, nutritional imbalances, structure damage an increase bulk density. Development a spot applicator with metering was planned to address problem. physical mechanical properties di-ammonium phosphate were determined. A new grooved belt type...

Knowledge of rice straw bunch in respect cutting energy is the important factor for optimization elements chopping system. A micro controller-based pendulum impact cutter was developed during 2019–21 at ICAR-Central Institute Agricultural Engineering, Bhopal, Madhya Pradesh. The system integrated with load cell, adjustable arm and shear approach angle (0–30 degree) experiment. In this study, lowest point Node 3 examined which just above ground surface. Three type blades SMS serrated, bar...

A healthy orchard necessitates well-balanced nutrition. In order to achieve a high yield, fertilizer application in the proper amount and position is important. Existing methods (band placement, pellet application, ring basin method) have limitations such as excessive soil acidity, nutrient imbalance, structure damage, bulk density rise, more. spot applicator that can dispense of at right site reduce waste, lowering pollution input costs. As result, novel grooved belt type metering system...

In many Indian regions, paddy wheat is the main crop rotation and facing problem of straw incorporation for seed bed preparation in short period. The handling combine harvested fields a significant issue rotation. order to solve this issue, efforts were carried out cut into small pieces by newly proposed counter-rotating blades, followed simultaneous rotary tiller soil. Therefore, tractor operated chopping cum tilling mixing machine was developed. study, three different blades (straw...

In this study, mechanical properties of paddy straw such as bending strength, shear strength and Young's modulus were determined through force-deformation curve using textural analyzer with 50 kg load cell. The at three moisture contents, i.e., 18.4% (M1), 13.5% (M2) 10.8% (M3), node positions, N1, N2 N3 loading rates, 25, 30 35 mm min-1, respectively. results revealed that content rate different positions significantly (p&lt;0.01) affected the straw, whose values varied from 5.35 to 17.34...

Limiting factors of general weed control methods create the situation for design-development new approaches based on robotics, automation, and sensor techniques.Several studies have documented yield loss associated with competition discrimination, identification, mechanisms.The automatic distinction between crop has importance in applications.Sensor-based approaches, machine vision systems, RTK GPS-based some other techniques are effective help improving yield.Robotic technology could...

Rotational speed is one of the most important parameters in performance any system. It becomes more vital when rotational measurement required on real-time basis. Measurement has a crucial role automation agricultural machineries for various purposes. The existing systems are susceptible to varying working environment. Therefore, it was necessary study available sensor. In this four different sensors (inductive proximity, Infrared (IR), Hall effect and optical proximity sensors) were tested...
