Volume 10, Issue 2 , 2020, , Pages 155-167

https://doi.org/10.22067/jam.v10i2.82853

Abstract
  IntroductionStereo vision is an approach to 3D information from multiple 2D views of a scene. The 3D information can be extracted from a pair image, as known stereo pair by estimating the relative depth of points in the scene.Soil aggregate size distribution is one of the most important issues in the ...  Read More

Influence of Conservation Tillage on some Soil Physical Properties and Crop Yield in Vetch-Wheat Rotation in Dryland Cold Region

I. Eskandari; V. Feiziasl

Volume 7, Issue 2 , 2017, , Pages 451-467

https://doi.org/10.22067/jam.v7i2.50933

Abstract
  Introduction Winter wheat is an important, well-adapted grain crop under dryland condition of the northwest of Iran. Soil water is the most limiting resource for crop growth in dryland areas. Therefore, farmers need to use crop residues and minimum tillage to control the soil erosion and effectively ...  Read More

Volume 7, Issue 2 , 2017, , Pages 480-490

https://doi.org/10.22067/jam.v7i2.53445

Abstract
  Introduction Improving the efficiency of all agricultural operations has always been important for farmers and engineers. It is well known that the force required for cutting a soil using narrow blades is a function of soil and environmental physical properties, tool shape geometry and the tool’s ...  Read More

Effect of blade vibration on mulch tillage performance under silt clay loam soil

B. Goudarzi; M. A. Asoodar; N. Kazemi

Volume 5, Issue 2 , 2015, , Pages 357-367

https://doi.org/10.22067/jam.v5i2.28510

Abstract
  Introduction: Mulch tillage system is an intermediate system which covers some of disadvantages of no tillage and conventional tillage systems. In farms in which tillage is done with a chisel plow, runoff and soil erosion have a less important relation to moldboard and disk plow and naturally absorption ...  Read More

Introducing a Strategy for Selection of Plowing Systems Using Hybrid SWOT-AHP Method (Khodabandeh, Zanjan)

K. Afsahi; A. Akram; R. Alimardani; M. Azizi

Volume 5, Issue 1 , 2015, , Pages 52-62

https://doi.org/10.22067/jam.v5i1.26308

Abstract
  For improvement or change in a plowing system, it is crucial that all important parameters to be taken in account. Recommendation of a tillage system should receive supports from research data as well as from skilled farmers in order to find a resolution to problems of that system. In this study, strengths, ...  Read More

Prediction of Soil Fragmentation During Tillage Operation Using Adaptive Neuro Fuzzy Inference System (ANFIS)

R. Sedghi; Y. Abbaspour Gilandeh

Volume 4, Issue 2 , 2014, , Pages 387-398

https://doi.org/10.22067/jam.v4i2.40425

Abstract
  Suitable soil structure is important for crop growth. One of the main characteristics of soil structure is the size of soil aggregates. There are several ways of showing the stability of soil aggregates, among which the determination of the median weight diameter of soil aggregates is the most common ...  Read More

Effects of Tillage Practices on Soil Penetration Resistance, Technical Parameters and Wheat Yield

S. M. J. Afzali; E. Javaheri

Volume 3, Issue 1 , 2013, , Pages 24-31

https://doi.org/10.22067/jam.v3i1.19711

Abstract
  This study was carried out to evaluate the effects of tillage practices (with different depths) on soil penetration resistance, technical parameters and grain yield of wheat crop. The experiment was conducted as a randomized complete block design with three replications for two years. Treatments included: ...  Read More

Design and Construction
Design, Construction and Test of a Three-point Hitch Dynamometer

M. Askari; M. H. Komarizade; N. Nobakht

Volume 1, Issue 2 , 2011

https://doi.org/10.22067/jam.v1i2.11353

Abstract
  For measuring the draft forces exerted by implements into tractor, we use the dynamometers that are divided into pull type or three-point hitch type. For measuring the forces between the tractor and the mounted implements, three-point hitch dynamometers are used. In this research, an adjustable three-point ...  Read More

Using Failure Mode and Effect Analysis (FMEA) for Performing Good Ploughing with Mouldboard

M. Namdari; Sh. Rafiee; A. Jafari

Volume 1, Issue 1 , 2011

https://doi.org/10.22067/jam.v1i1.10074

Abstract
  Farm management needs creative methods to success. FMEA (Failure Modes and Effects Analysis) is a new method to analyze potential reliability problems in the development cycle of the project, making it easier to take actions to overcome such issues, thus enhancing the reliability through design or process. ...  Read More
