Agrovoc Terms :

moisture content; berberis; physical properties

Abstract :

In order to enhance the mechanization level of harvest and post-harvest operations of Berberis fruit, as one of the major and local crops of south Khorasan province, some of its physical properties were investigated. Different dimensions, geometrical mean diameter, sphericity, surface area, mass of thousand fruit, true density, bulk density, porosity, static coefficient of friction and the rep ...

Agrovoc Terms :

measurement; harvesting; corn; combine losses

Abstract :

Corn harvesting involves some losses. These losses result in decreased benefits. It is almost impossible to lower losses to zero percent but it can be controlled in an acceptable level. As a result of this research, appropriate methods are introduced to decrease losses and reduce waste. In this project, losses in different part of combine were measured and evaluated according to the available ...

Agrovoc Terms :

soil inversion; tillage; clod mean weight diameter; failure modes and effects analysis

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. Anticipating these failure modes, being the central step in the analysis, needs to be ca ...

Agrovoc Terms :

electrical conductivity; ec map; soil salinity; regression mode

Abstract :

The issue of soil salinity is one of the snags for increasing agricultural productivity, which must be inhibited by appropriate devise and scientific management. One way to identify salty areas of farm lands is to prepare salinity maps. In this study, a prototype soil apparent electrical conductivity measuring and mapping device, was designed and built. This device employs direct contact metho ...

Agrovoc Terms :

rototiller; soil tillage; soil crushing rate

Abstract :

In recent years using rototillers in orchards and small fields especially in northern areas of Iran has been increased. In this study, a multi-function rototiller was developed and its performance was analyzed and evaluated in the field conditions. The specifications of this machine were determined according to the standard and operational situation. The calculations were performed for determi ...

Agrovoc Terms :

tractor test; weighting; agricultural mechanization; topsis

Abstract :

Agricultural mechanization goal is to maximize the utility. Establishment of subsidies systemization and Iran incorporation with World Target Organization (WTO), choosing an appropriate technology will be more important. Agricultural development is due to correct mechanization and choosing an appropriate tractor is one of mechanization implementation bases. In the paper, criteria involved in c ...

Agrovoc Terms :

small farms; agricultural mechanization

Abstract :

The major part of agriculture in Iran and especially in Khorasan province is yeoman farmers, and often the parts are less than one hectare. To evaluate the status of small farm mechanization (less than two hectares) in Khorasan Razavi province, three agricultural sub-regions that running small farms were identified. This research was carried out in 2009. The questionnaire was prepared for gath ...

Agrovoc Terms :

three-point hitch, draft measurement; tillage; dynamometer; design & construction

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 hitch dynamometer with a draft capacity of 25 kN was designed and built which is made up ...

Abstract :

In this study evaluation and comparison of various interpolation approaches for estimation un-sampled values of soil Organic Matter Content (OMC) and soil texture is presented. The main objective is to develop a precision method for generation of management maps for variable rate application of herbicide that eventuate to save herbicide application and to reduce adverse impact on the environme ...

Agrovoc Terms :

spatial distribution; classification; site-specific management; neural network

Abstract :

With the rise of new powerful statistical techniques and neural networks models, the development of predictive species distribution models has rapidly increased in ecology. In this research, a learning vector quantization (LVQ) and multi layer perceptron (MLP) neural network models have been employed to predict, classify and map the spatial distribution of A. repens L. density. This method was ...
