EFFECT OF FERTILIZERS ON YIELD COMPONENT ATTRIBUTES, YIELD AND QUALITY IN SOYBEAN CROP

The paper aimed to present the effects of different types of fertilizers on several soybean quantitative traits (plantheight, first pod height, number of pods per plant, number of grain per plant, grain yield per plant, 1000-grain weightand grain yield) and seeds’ composition (dry matter, protein content, ash content, oil content, total carbohydrates, totalflavonoids, total phenols and total carotenoids content). The experiment was conducted in 2019, in the experimentalfield of Soybean Breeding Laboratory from the Agricultural Research and Development Station Turda (ARDS Turda),and included 15 fertilization trials. An early maturing soybean variety (Caro TD) obtained at ARDS Turda was used forthe experiment. The results showed that increases in yield were obtained with various combinations of the commercialfertilizer. The application of N20P20K0 combined with seed treatment and foliar Bio-fertilizer with 80% amino acids,significantly increased the values for all quantitative traits and also grain yield, while with respect to seed compositionthe best ranked type of treatment was T7(ecological products).
