Abstract


Conservation agriculture comes with a set of principles to implementation and development of sustainable
technologies with the aim of retaining sufficient quantities of vegetal remains on the soil surface for soil protection against
erosion, water evaporation and surface leakage, for better use of rainfall and improve the physical, chemical and biological
soil properties associated with long-term stable yeld. The research was aimed at determining the influence of new foliar
fertilizers and soil tillage systems on assimilation .The research method used for assimilation and the physiological
parameters determination of Turda 332 maize hybrid was non-destructive (the leaves have not been detached from the
plant) and was based on the use of a CIRAS-3 leaf gas analyzer which simultaneously determines several physiological
and environmental indicators. The highest values of assimilation were recorded in conservative tillage systems being
between 37.9 şi 42.9 μmolm

Conservation agriculture comes with a set of

sustainable technologies with the aim of retaining
sufficient quantities of vegetal remains on the soil
surface for soil protection against erosion, water
evaporation and surface leakage, for better use of
rainfall and improve the physical, chemical and
biological soil properties associated with long-term
stable yeld [5, 7, 11].
