The location information of strip roads in thinnings and the numerical variables are one aspect timber harvest quality information. ideal automatic management for mechanized logging is that calculated reported based on data collected by forest machines. At present, means laborious, manual, field-based, post-harvest measurements. aim this study was to develop an method compute harvested stands a...

In view of the problem plant entanglement threshing roller in process mechanized flax harvesting, a comb-brush air-suction composite capsule harvesting test stand was designed based on method capsules independently and then breaking to thresh them. The following four parameters were selected as experimental factors: shape comb tooth cross-section, rotational speed roller, relative machine trave...

this study investigated the status of mechanized power and self-propelled rice cultivation machinery in guilan province in northern iran. the raw data was obtained from 2013 statistics of the agricultural jihad organization of guilan province. power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

Mechanized timber harvesting is cost efficient and highly productive. However, mechanized operations are often associated with several environmental problems, including soil compaction disturbance. Soil impedes air circulation between the atmosphere, which in turn results increased concentrations of CO2 within pores. In this study, we investigated impact forest machine traffic on conditions to ...

quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. this study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in gorgan city. cross-section survey data were gathered...

katoul is a new soybeam cultivar originated from a genotype named d.p.x.3589 imported from the united states of american in 1990. this genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in gorgan and other research stations during 1999-2002. the mean seed yield of d.p.x.3589 in all these experiments was 3333 kgha-1 ...
