Cut-to-length (CTL) timber harvesting technology currently accounts for approximately 90% of Caspian forests. The technology involves felling, branching, cross-cutting, and then the skidder carries the logs to a landing, where the timber is temporarily stored, sorted and assembled for transportation to the mill.

The application of different modern logging systems depends on the silvicultural aims and methodologies. Depending upon these specifications the appropriate technique must be selected. This is the basic condition, which leads to a specific logging system in Central European and especially in German forestry. In the following an overview is to be given upon the different applications of full-mec...
Mechanized harvesting technologies with shaking systems for fruit industry have been widely investigated and significantly developed over the past several decades which were presented by a large amount of literature. This paper reviews research development progress mechanized fruits systematically focus on theoretical study, crop variety, system categories, abscission chemical agents, their act...
A brief overview of the state research on selection new constant biotechnological lines – donors glyphosate resistance and prospects creating hybrids sugar beet are presented. Experimental data nature inheritance in different genotypes (mmSxxzz, mmNxxzz, MMTOp, etc.) were obtained. For first time, separate joint fruit lines-donors with 90-100% In competitive environmental tests, glyphosate-tole...
