Abstract
Research was conducted using Andrada winter wheat variety created at the Agricultural Research and Development Station Turda. The crop was treated with two types of foliar fertilizers, Folimax Gold and MicrofertU which were applied in two tillage systems: conventional and no-tillage. The main purpose of this paper is to assess the influence of foliar fertilization in the two systems of conventional tillage and conservative systems with no-tillage. Various growth stages of the wheat crop, in achieving high yields and quality indices were assessed. The promotion and identification of physiological mechanisms in wheat are useful in assessing biological development, correlated with the productivity elements of winter wheat. Measurements of assimilation of the physiological parameters and chlorophyll concentration were performed on the standard flag leaf five days from the last treatment, using foliar fertilizers considering the duration of adaptation of tissues in flag leaf. Measurements were performed five times per plant and five plants per variant, with three repetitions in June. Technology used in wheat cultivation showed that the net assimilation, physiological parameters, and production were higher, registering higher values for the conventional system (tilling), ranging between 27-30 μmolm-2 s-1, and an increase of production, of over 700 kg ha-1. The values were statistically confirmed, as being significantly positive, compared to those from the conservative no-tillage system, in the conditions of the Transylvanian Plain. Physiological parameters taken into study had higher values for the conventional system in the variants treated with foliar fertilizers, compared to the no-tillage system, leaf to air vapor pressure deficit (VPD) being inversely proportional. Foliar fertilization applied to the Andrada wheat variety has beneficially influenced the quality indices in the two tillage systems, the percentage of protein obtained being between 12.1-13.8%, gluten between 23.5-27.3%, Zeleny index between 35-48%, and the mass of one thousand grains (MTG) was between 50-53.1 g.
