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-2s-1 CO2 and the fertilized variant of the Haifa foliar product 40.74 μmolm-2s-1 CO2.
