RESULTS REGARDING THE INFLUENCE OF GENETIC AND TECHNOLOGICAL FACTORS ON YIELD COMPONENTS AT SPRIG WHEAT PUBLISHEDS. BRĂILEANU, I. RACZ, M. DUDA, ROZALIA KADAR
The aim of our experience is to improve the cultivation technology of spring wheat through the accumulation of new knowledge that contributes to the scientific and practice basis by using the best spring varieties, which correlated by the number of sowing seed at square meter and rational fertilizing lead to increasing qualitative and quantitative production, within the limits of economic efficiency and protecting environment. In order to achieve the proposed objectives, it was organized a three factorial experience, 3A ( variety ) x 3B ( number of sowing seeds ) x 3C ( doze of fertilizers ) being taken into study three factors with 3 replications. The tested varieties were: Pădureni (from Romania), GK Marcius and GK Tavasz (from Hungary). Number of sowing seeds were: 250 g.s./m 2 , 375 g.s/m 2 and 500g.s./m 2 . They were used the following doze of fertilizers: N 70 P 70 K 0 , N 100 P 100 +foliar, N 120 P 120 K 0 . The paper presents the yields components on spring wheat: number of fertile tillers/plant, number of fertile spikelets/spike, number of grain /spike, thousand kernel weight (TKW). This study allow to us putting out of the phenomena that takes place during growing season and different influences of research factors on yield.
