THE INTERACTION OF THE TECHNOLOGICAL FACTORS ON THE PRODUCTION OF THE DROPIA AUTUMN WHEAT CULTIVAR PUBLISHEDMariana Popovici, Eva Bucurean
The study of the interaction of several factors, in the case of wheat yield technology, lead to the elaboration of various and more precise conclusions, than in the case of a single factor experiences. Due to the previously mentioned information, I have analyzed the interaction of the technological factors used in the yield process of the Dropia autumn wheat cultivar seeds, in order to deal with a more precise interpretation of the overall effects of these factors. In order to obtain a bigger and constant production per hectare, efficient under the economical aspect, the appliance of the nitrogen fertilizers must take into account the necessities of the wheat implied for this element and the level of supplies present in the soil. Due to this fact, the appliance of the chemical nitrogen fertilizers becomes necessary and compulsory in order to ensure the continuous nourishment of the plants with this element, essential for their natural evolution. To emphasize the favorable effect of the use of the nitrogen fertilizers, the interaction between the fertilization level with nitrogen and the sowing period, the interaction between the fertilization level and the sowing density were analysed. The interaction between the sowing period and the sowing density was analysed too.
