Abstract


The paper presents the results of the researches carried out during the period 2017-2019, under the conditions of the Târnavelor Vineyard, in the Jidvei-Alba area, regarding the influence of some technological factors on the level of grape production. The factors considered in the study were: Factor A - irrigation regime, with graduations a1 - non-irrigated, a2 - irrigated at 50% IUA; Factor B - fertilization, with graduations b1 - basic fertilization, b2 - basic fertilization + chemical fertilization; b3 - organic fertilization; Factor C, biological material, with graduations c1 - Muscat Ottonel variety, c2 - Feteasca Regala variety, c3 - Sauvignon Blanc variety. The production results recorded during the three years of experimentation highlighted in particular the favorable effect of irrigation on the production of grapes, in all three varieties, regardless of the applied fertilization level.
