The Influence of Technological Elements on some Production Components for the Spring Wheat

The production level is determined by the interaction between the biological limits of the plants and the influence of the applied technological elements. The research has been carried out in the year 2010 in the USAMV experimental field in Jucu. Three varieties of spring wheat have been used in the study, respectively: Pădureni, GK Március and GK Tavasz. The one thousand grains weight (TGW) is an incontestably important productivity element with implications on quality, as the embryo dimension and the quantity of reserve substances for germination and sprout depend on it. TGW is in close connection to production, as big grain varieties can have a larger production capacity. The mass/weight of 1000 grains is firstly influenced by the genetic factor, respectively by the variety (F= 151.905***, according to the Fisher sample), followed by the interaction variety x density (F = 13.156***), and then by density and less by fertilisation. The Pădureni and GK Március varieties have similar TGW values, and GK Tavasz has the weight of 1000 grains 4.39 g smaller than Pădureni, respectively 32.88 g, the largest TGW values being recorder for a density of 250 wg/m2. The average weight of grains/ear was 1.62 g for the Pădureni variety, the other varieties having quite similar values for this aspect. Out of the researched factors, the variety has the largest influence on the number of grains on the ear (F = 73.850***), and then fertilisation, the interaction V x D and the density factor. The average number of grains/ear was 42.63 with Pădureni, 39.57 with GK Március and 47.14 with GK Tavasz.
