Researchers around the world have focused on autonomous agriculture with systems encompassing greenhouse, orchard, field, and other applications. Research has shown the potential and ability of the technology to allow a vehicle or selection of vehicles to follow a specified task. In this study, one aspect of the problem, that of operating a tractor−cart combination in conjunction with a small−g...

Various plants and resources such as orchards are vulnerable to the detrimental effects of successful invasions by alien animal or plant species. To outline an appropriate policy response, we first use renewal theory to construct a stochastic model of optimal orchard management in the presence of a deleterious alien species. Next, we derive the orchard manager’s long run expected cost of orchar...

Abstract. Researchers around the world have focused on autonomous agriculture, with systems encompassing greenhouse, orchard, field and other applications. Research has shown the potential and ability of the technology to allow a vehicle or selection of vehicles to follow a specified task. In this study, one aspect of the problem, that of operating a tractor-cart combination in conjunction with...

Nowadays in agriculture the labour work is very important. This paper is proposed to reduce the labour work in fruit picking by using the image clustering algorithm in a machine vision system. For plucking fruits such as citrus, apple, jujube, etc., so many different classification techniques were proposed. This paper focus on the automatic detection of the pomegranate fruits in an orchard. The...

this study was conducted to investigate the impact of land use change on some of carbon components in safashahr area, fars province. four land uses (destroyed rangeland, agricultural land, new and old apple orchard) were selected. sampling was done randomly from two depths (0-20 and 20-50 cm) of each land use. particulate organic matter (pom) and extractable carbohydrate by hot water were measu...

In this paper we present an approach to tree recognition and localisation in orchard environments for tree-crop applications. The method builds on the natural structure of the orchard by first segmenting the data into individual trees using a Hidden Semi-Markov Model. Second, a descriptor for representing the characteristics of the trees is introduced, allowing a Hidden Markov Model based match...

This paper addresses the refactoring of an agricultural vehicle localization system and its deployment and field-testing in apple orchards. The system enables affordable precision agriculture in tree fruit production by providing the vehicle’s position in the orchard without the use of expensive differential GPS. The localization methodology depends only on the wheel and steering encoders and t...

Both the Vogel Spindle and Spanish Bush systems will allow for the development of a “pedestrian orchard”. A pedestrian orchard is defined as an orchard where two-thirds of the crop can be harvested from the ground, without the use of tall ladders (Fig. 1). Harvesting fruit from the ground greatly enhances worker productivity. In a study that I conducted in The Dalles, Oregon pickers were able t...

The precise management of orchards cannot do without the support of various orchard field data, and the orchard field data server is an effective solution thereto. The orchard field data server consists of data acquisition unit, data communication unit, data analysis unit and such diversified server sockets of user terminal as supportive personal computer (PC), notebook computer, mobile phone a...

The measurement and control of soil moisture are the key technologies of precision agriculture. In order to real-time detect soil moisture content faster and more accurately, a portable soil moisture sensor based on NIR spectroscopy was developed. With the sixty soil samples collected from a winter jujube orchard, a linear regression model was established. The determination coefficients of the ...
