Abstract:
Considering that vegetal production is related to the use of fertilizers or land works, this paper investigates the correlation between plant production in Romania and fertilizers in 1990-2015, but also checks on the efficiency of minimum tillage system. At macroeconomic level, there was a long and short bidirectional relationship between cereals’ production in Romania and the quantity of natural fertilizers in the period 1990-2015. The statistical results on experimental data indicated that there are not significant differences between conventional systems and minimum tillage systems for the three plants in terms of production, power balance efficiency and energy utilization at 5% level of significance.
