[Tillage energetical efficiency in wheat]
1995
Nedeff, V. (Statiunea de Cercetari Agricole, Secuieni-Neamt (Romania))
Reduced tillage technologies in wheat, having as an aim to obtain yields almost constant on variants, decreased the fuel consumption until 55 percent, increased energetical efficiency until 316 kWh/ha and increased energetical output until 0.38 percent. The weight of expenses needed for one passage tillage, from the whole direct active energy, was great (35 percent), but if it refered to the whole of the energy consumption (4828 - 5418 kWh/ha) and the high values of indirect active energy (3965 kWh/ha), this decrease until 5 percent.
