INFLUENCE OF TECHNOLOGICAL FACTORS ON QUALITY AND SOME YIELD ELEMENTS OF ANDRADA WINTER WHEAT VARIETY, CULTIVATED IN TRANSLILVANIA PLAIN CONDITIONS

Abstract

For evaluating the influence of tillage system, fertilization and phytosanitary treatment on wheat seed quality, an experiment was conducted at Research and Development Station for Agriculture (RDSA) Turda. Seeds of Andrada winter wheat variety were analysed for: Ash [%], G, Gluten [%], HlWeight [kg/hl], L [mm], Moisture [%], P [mm], P/L, Protein [%], Protein_DM [%], W [Jx10E-4], Zeleny [ml]. Generally, quality was influenced by fertilization and phytosanitary treatment, small variation depending on tillage system being identified. In the no-tillage version, when the mineral fertilizer N₁₃₄P₄₈K₄₈ and when seed treatment and two foliar treatments were applied maximum values wwre obtained for: prorein content (11.69%), gluten content (22.4%), Zeleny index (33 ml). In terms of hectoliter weight, the highest value of 77.75 kg/hl was obtained in the classical crop system, when fertilization with complex fertilizer N₈₈P₄₈K₄₈ together with seed treatment and one foliar treatment were applied. In terms of yield elements, the negative relationship between quality and yield is highlighted, namely if in the „no tillage system” good results for quality were obtained, in classic system, high values for plant height, numebr of grains/spike, grain weight/spike and for spike lenght compared to „minimum” or „no tillage” were identified.
