These effects on tree growth, which may persist for several decades (Hatchell et al. 1970, Butt 1987, Miller et al. 1996), may lead to shortand long-term reductions in tree growth and forest productivity. The level of soil disturbance will vary with soil texture, forest floor thickness, and soil water content at time of harvest (Miller and Sirois 1986, Corns 1988). In addition, machine type, si...

rice is one of the most important staple cereals‏ ‏in iran and has a main role in providing ‎the food ‎security. harvesting by hand postpone the rice harvesting stage, and facing late season ‎rainfall, and increase of yield losses during harvesting. to determine the most suitable ‎harvesting method in gilan, three different harvesting methods (by hand, harvester and ‎combine) were considered as...

the main purpose of this study is measuring and comparing of peanut harvesting loss in manual and mechanical methods in addition to economic analysis of them. hence, a field was selected in astaneh-ashrafiyeh and divided to three different plots. two plots were applied to measure mechanical harvesting loss and third one was applied for manual harvesting loss. according to test results, the lowe...

Continuing progress in machine learning (ML) has led to significant advancements agricultural tasks. Due its strong ability extract high-dimensional features from fruit images, deep (DL) is widely used detection and automatic harvesting. Convolutional neural networks (CNN) particular have demonstrated the attain accuracy speed levels comparable those of humans some harvesting fields. This paper...

Around the globe, various types of forest machinery are employed to conduct fully mechanized ground-based timber harvesting. In Pacific Northwest, whole-tree harvesting method remains dominant. While machine-integrated sensors provide accurate productivity information in cut-to-length method, is more complicated determine This literature review compiles and analyses existing evidence on studies...

Automation continues to play a greater role in agricultural production with commercial systems now available for machine vision identification of weeds and other pests, autonomous weed control, robotic harvesters fruits vegetables. The growing availability machines agriculture indicates that there are opportunities increase automation cotton production. This article considers how current future...
