The article presents the results that can be a prerequisite for the introduction of a pre-sowing electrotreatment of winter rape seeds into the production process. The results of photon emission by rape seeds after electrical stimulation are highly correlated with the data obtained during determination of its sowing qualities and field germination. Absorption and transformation of the energy of the...
This paper investigates the possibility of improving the vibration isolation of a tractor cab by changing the stiffness of its rubber-metal supports. A spectral analysis of the vibration isolation properties of these supports is presented. The research was conducted on a BELARUS 1221 tractor at idling, at the maximum engine speed, with no load. The cab was mounted on rubber-metal vibration absorbers...
Majority of past research on agricultural product production is related with irrigated areas. Thus, the purpose of this study was to evaluate the energy use pattern in wheat production planted as dry farming in Northwest of Iran. Initial data were collected by means of questionnaires from farmers and agricultural experts in the area. Energy use efficiency indices, net energy, specific energy, energy...
